Is it possible to make input act like a link (Chrome) - javascript

I want an input type="button" act like a link to the browser (so, it is possible to right click on the input and see context menu for the links(open link in a new tab, open link in a new window etc).
I have a form with a submit button:
<input type="submit" value="Run Query"/>
In order to create a link and have this context-menu, I replaced input with:
Run Query
But this way "open link in a new tab" opens the same page(due to the href attribute).
I know that you can just ctrl+click on the <input type="submit"/> to open it in a new tab, but if the input tag is present, there is no context menu for it in Chrome.
Is it possible to create an input that would have the same context menu as a link? Or any trick to tell the browser to add this functionality to the input tag?

If I understand your problem correctly, you want to submit the form to a new tab?
Then you could use target="_blank" on the form element.
<form action="" method="POST" target="_blank" >
<input type="submit" />
</form>

This will use the query string to pass the value of each input field to a new window or tab and submit it. It won't work if you're posting files (a workaround would be to immediately upload the file when selected, give it an id and store that in a hidden field, so the file id is the one being posted).
Note that this is an example and you should use something better for dealing with query strings and browser compatibility (it's only tested on Chrome). You should test it thoroughly in other browsers before shipping this! I also have no clue how it's going to work in browsers for iOS/Android/Windows Phones etc. What I'm trying to say is that you probably shouldn't use this.
<body>
<form action="http://google.com">
<input type="text" name="stuff" value="" />
<input type="text" name="q" value="" />
Submit
</form>
<script>
!function () {
var form = document.querySelector("form")
var submitButton = document.querySelector("a")
var queryString = location.search.slice(1).split("&").reduce(function (seed, str) {
var pair = str.split("=")
seed[pair[0]] = decodeURIComponent(pair[1])
return seed
}, {})
Object.keys(queryString).forEach(function (qsKey) {
var formEl = form.querySelector("[name='" + qsKey + "']")
if(formEl)
formEl.value = queryString[qsKey]
})
if(queryString.submit)
form.submit()
submitButton.addEventListener("contextmenu", updateHref) // Update on right click
submitButton.addEventListener("click", function (e) {
if(e.altKey || e.ctrlKey || e.shiftKey || e.which === 2 /* middle mouse button */) {
updateHref()
} else {
e.preventDefault()
form.submit()
}
})
function updateHref() {
var values = [].slice.call(form.elements).map(function (el) {
return el.name + "=" + encodeURIComponent(el.value)
})
submitButton.href = location.pathname + "?submit=1&" + values.join("&")
}
}()
</script>
</body>

How to pass clicked button value to javascript on form submit [duplicate]

I have a .submit() event set up for form submission. I also have multiple forms on the page, but just one here for this example. I'd like to know which submit button was clicked without applying a .click() event to each one.
Here's the setup:
<html>
<head>
<title>jQuery research: forms</title>
<script type='text/javascript' src='../jquery-1.5.2.min.js'></script>
<script type='text/javascript' language='javascript'>
$(document).ready(function(){
$('form[name="testform"]').submit( function(event){ process_form_submission(event); } );
});
function process_form_submission( event ) {
event.preventDefault();
//var target = $(event.target);
var me = event.currentTarget;
var data = me.data.value;
var which_button = '?'; // <-- this is what I want to know
alert( 'data: ' + data + ', button: ' + which_button );
}
</script>
</head>
<body>
<h2>Here's my form:</h2>
<form action='nothing' method='post' name='testform'>
<input type='hidden' name='data' value='blahdatayadda' />
<input type='submit' name='name1' value='value1' />
<input type='submit' name='name2' value='value2' />
</form>
</body>
</html>
Live example on jsfiddle
Besides applying a .click() event on each button, is there a way to determine which submit button was clicked?
I asked this same question: How can I get the button that caused the submit from the form submit event?
I ended up coming up with this solution and it worked pretty well:
$(document).ready(function() {
$("form").submit(function() {
var val = $("input[type=submit][clicked=true]").val();
// DO WORK
});
$("form input[type=submit]").click(function() {
$("input[type=submit]", $(this).parents("form")).removeAttr("clicked");
$(this).attr("clicked", "true");
});
});
In your case with multiple forms you may need to tweak this a bit but it should still apply
I found that this worked.
$(document).ready(function() {
$( "form" ).submit(function () {
// Get the submit button element
var btn = $(this).find("input[type=submit]:focus" );
});
}
This works for me:
$("form").submit(function() {
// Print the value of the button that was clicked
console.log($(document.activeElement).val());
}
When the form is submitted:
document.activeElement will give you the submit button that was clicked.
document.activeElement.getAttribute('value') will give you that button's value.
Note that if the form is submitted by hitting the Enter key, then document.activeElement will be whichever form input that was focused at the time. If this wasn't a submit button then in this case it may be that there is no "button that was clicked."
There is a native property, submitter, on the SubmitEvent interface.
Standard Web API:
var btnClicked = event.submitter;
jQuery:
var btnClicked = event.originalEvent.submitter;
Here's the approach that seems cleaner for my purposes.
First, for any and all forms:
$('form').click(function(event) {
$(this).data('clicked',$(event.target))
});
When this click event is fired for a form, it simply records the originating target (available in the event object) to be accessed later. This is a pretty broad stroke, as it will fire for any click anywhere on the form. Optimization comments are welcome, but I suspect it will never cause noticeable issues.
Then, in $('form').submit(), you can inquire what was last clicked, with something like
if ($(this).data('clicked').is('[name=no_ajax]')) xhr.abort();
Wow, some solutions can get complicated! If you don't mind using a simple global, just take advantage of the fact that the input button click event fires first. One could further filter the $('input') selector for one of many forms by using $('#myForm input').
$(document).ready(function(){
var clkBtn = "";
$('input[type="submit"]').click(function(evt) {
clkBtn = evt.target.id;
});
$("#myForm").submit(function(evt) {
var btnID = clkBtn;
alert("form submitted; button id=" + btnID);
});
});
I have found the best solution is
$(document.activeElement).attr('id')
This not only works on inputs, but it also works on button tags.
Also it gets the id of the button.
Another possible solution is to add a hidden field in your form:
<input type="hidden" id="btaction"/>
Then in the ready function add functions to record what key was pressed:
$('form#myForm #btnSubmit').click(function() {
$('form#myForm #btaction').val(0);
});
$('form#myForm #btnSubmitAndSend').click(function() {
$('form#myForm #btaction').val(1);
});
$('form#myForm #btnDelete').click(function() {
$('form#myForm #btaction').val(2);
});
Now in the form submition handler read the hidden variable and decide based on it:
var act = $('form#myForm #btaction').val();
Building on what Stan and yann-h did but this one defaults to the first button. The beauty of this overall approach is that it picks up both the click and the enter key (even if the focus was not on the button. If you need to allow enter in the form, then just respond to this when a button is focused (i.e. Stan's answer). In my case, I wanted to allow enter to submit the form even if the user's current focus was on the text box.
I was also using a 'name' attribute rather than 'id' but this is the same approach.
var pressedButtonName =
typeof $(":input[type=submit]:focus")[0] === "undefined" ?
$(":input[type=submit]:first")[0].name :
$(":input[type=submit]:focus")[0].name;
This one worked for me
$('#Form').submit(function(){
var btn= $(this).find("input[type=submit]:focus").val();
alert('you have clicked '+ btn);
}
Here is my solution:
$('#form').submit(function(e){
console.log($('#'+e.originalEvent.submitter.id));
e.preventDefault();
});
If what you mean by not adding a .click event is that you don't want to have separate handlers for those events, you could handle all clicks (submits) in one function:
$(document).ready(function(){
$('input[type="submit"]').click( function(event){ process_form_submission(event); } );
});
function process_form_submission( event ) {
event.preventDefault();
//var target = $(event.target);
var input = $(event.currentTarget);
var which_button = event.currentTarget.value;
var data = input.parents("form")[0].data.value;
// var which_button = '?'; // <-- this is what I want to know
alert( 'data: ' + data + ', button: ' + which_button );
}
As I can't comment on the accepted answer, I bring here a modified version that should take into account elements that are outside the form (ie: attached to the form using the form attribute). This is for modern browser: http://caniuse.com/#feat=form-attribute . The closest('form') is used as a fallback for unsupported form attribute
$(document).on('click', '[type=submit]', function() {
var form = $(this).prop('form') || $(this).closest('form')[0];
$(form.elements).filter('[type=submit]').removeAttr('clicked')
$(this).attr('clicked', true);
});
$('form').on('submit', function() {
var submitter = $(this.elements).filter('[clicked]');
})
You can simply get the event object when you submit the form. From that, get the submitter object. As below:
$(".review-form").submit(function (e) {
e.preventDefault(); // avoid to execute the actual submit of the form.
let submitter_btn = $(e.originalEvent.submitter);
console.log(submitter_btn.attr("name"));
}
In case you want to send this form to the backend, you can create a new form element by new FormData() and set the key-value pair for which button was pressed, then access it in the backend. Something like this -
$(".review-form").submit(function (e) {
e.preventDefault(); // avoid to execute the actual submit of the form.
let form = $(this);
let newForm = new FormData($(form)[0]);
let submitter_btn = $(e.originalEvent.submitter);
console.log(submitter_btn.attr("name"));
if (submitter_btn.attr("name") == "approve_btn") {
newForm.set("action_for", submitter_btn.attr("name"));
} else if (submitter_btn.attr("name") == "reject_btn") {
newForm.set("action_for", submitter_btn.attr("name"));
} else {
console.log("there is some error!");
return;
}
}
I was basically trying to have a form where user can either approve or disapprove/ reject a product for further processes in a task.
My HTML form is something like this -
<form method="POST" action="{% url 'tasks:review-task' taskid=product.task_id.id %}"
class="review-form">
{% csrf_token %}
<input type="hidden" name="product_id" value="{{product.product_id}}" />
<input type="hidden" name="task_id" value="{{product.task_id_id}}" />
<button type="submit" name="approve_btn" class="btn btn-link" id="approve-btn">
<i class="fa fa-check" style="color: rgb(63, 245, 63);"></i>
</button>
<button type="submit" name="reject_btn" class="btn btn-link" id="reject-btn">
<i class="fa fa-times" style="color: red;"></i>
</button>
</form>
Let me know if you have any doubts.
Try this:
$(document).ready(function(){
$('form[name="testform"]').submit( function(event){
// This is the ID of the clicked button
var clicked_button_id = event.originalEvent.submitter.id;
});
});
$("form input[type=submit]").click(function() {
$("<input />")
.attr('type', 'hidden')
.attr('name', $(this).attr('name'))
.attr('value', $(this).attr('value'))
.appendTo(this)
});
add hidden field
For me, the best solutions was this:
$(form).submit(function(e){
// Get the button that was clicked
var submit = $(this.id).context.activeElement;
// You can get its name like this
alert(submit.name)
// You can get its attributes like this too
alert($(submit).attr('class'))
});
Working with this excellent answer, you can check the active element (the button), append a hidden input to the form, and optionally remove it at the end of the submit handler.
$('form.form-js').submit(function(event){
var frm = $(this);
var btn = $(document.activeElement);
if(
btn.length &&
frm.has(btn) &&
btn.is('button[type="submit"], input[type="submit"], input[type="image"]') &&
btn.is('[name]')
){
frm.append('<input type="hidden" id="form-js-temp" name="' + btn.attr('name') + '" value="' + btn.val() + '">');
}
// Handle the form submit here
$('#form-js-temp').remove();
});
Side note: I personally add the class form-js on all forms that are submitted via JavaScript.
Similar to Stan answer but :
if you have more than one button, you have to get only the
first button => [0]
if the form can be submitted with the enter key, you have to manage a default => myDefaultButtonId
$(document).on('submit', function(event) {
event.preventDefault();
var pressedButtonId =
typeof $(":input[type=submit]:focus")[0] === "undefined" ?
"myDefaultButtonId" :
$(":input[type=submit]:focus")[0].id;
...
}
This is the solution used by me and work very well:
// prevent enter key on some elements to prevent to submit the form
function stopRKey(evt) {
evt = (evt) ? evt : ((event) ? event : null);
var node = (evt.target) ? evt.target : ((evt.srcElement) ? evt.srcElement : null);
var alloved_enter_on_type = ['textarea'];
if ((evt.keyCode == 13) && ((node.id == "") || ($.inArray(node.type, alloved_enter_on_type) < 0))) {
return false;
}
}
$(document).ready(function() {
document.onkeypress = stopRKey;
// catch the id of submit button and store-it to the form
$("form").each(function() {
var that = $(this);
// define context and reference
/* for each of the submit-inputs - in each of the forms on
the page - assign click and keypress event */
$("input:submit,button", that).bind("click keypress", function(e) {
// store the id of the submit-input on it's enclosing form
that.data("callerid", this.id);
});
});
$("#form1").submit(function(e) {
var origin_id = $(e.target).data("callerid");
alert(origin_id);
e.preventDefault();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<form id="form1" name="form1" action="" method="post">
<input type="text" name="text1" />
<input type="submit" id="button1" value="Submit1" name="button1" />
<button type="submit" id="button2" name="button2">
Submit2
</button>
<input type="submit" id="button3" value="Submit3" name="button3" />
</form>
This works for me to get the active button
var val = document.activeElement.textContent;

Form submited only after submit button was clicked.

I was able to use jQuery originalEvent.submitter on Chrome with an ASP.Net Core web app:
My .cshtml form:
<div class="form-group" id="buttons_grp">
<button type="submit" name="submitButton" value="Approve" class="btn btn-success">Approve</button>
<button type="submit" name="submitButton" value="Reject" class="btn btn-danger">Reject</button>
<button type="submit" name="submitButton" value="Save" class="btn btn-primary">Save</button>
...
The jQuery submit handler:
#section Scripts {
#{await Html.RenderPartialAsync("_ValidationScriptsPartial");}
<script type="text/javascript">
$(document).ready(function() {
...
// Ensure that we log an explanatory comment if "Reject"
$('#update_task_form').on('submit', function (e) {
let text = e.originalEvent.submitter.textContent;
if (text == "Reject") {
// Do stuff...
}
});
...
The jQuery Microsoft bundled with my ASP.Net Core environment is v3.3.1.
Let's say I have these "submit" buttons:
<button type="submit" name="submitButton" id="update" value="UpdateRecord" class="btn btn-primary">Update Record</button>
<button type="submit" name="submitButton" id="review_info" value="ReviewInfo" class="btn btn-warning sme_only">Review Info</button>
<button type="submit" name="submitButton" id="need_more_info" value="NeedMoreInfo" class="btn btn-warning sme_only">Need More Info</button>
And this "submit" event handler:
$('#my_form').on('submit', function (e) {
let x1 = $(this).find("input[type=submit]:focus");
let x2 = e.originalEvent.submitter.textContent;
Either expression works. If I click the first button, both "x1" and "x2" return Update Record.
I also made a solution, and it works quite well:
It uses jQuery and CSS
First, I made a quick CSS class, this can be embedded or in a seperate file.
<style type='text/css'>
.Clicked {
/*No Attributes*/
}
</style>
Next, On the click event of a button within the form,add the CSS class to the button. If the button already has the CSS class, remove it. (We don't want two CSS classes [Just in case]).
// Adds a CSS Class to the Button That Has Been Clicked.
$("form :input[type='submit']").click(function ()
{
if ($(this).hasClass("Clicked"))
{
$(this).removeClass("Clicked");
}
$(this).addClass("Clicked");
});
Now, test the button to see it has the CSS class, if the tested button doesn't have the CSS, then the other button will.
// On Form Submit
$("form").submit(function ()
{
// Test Which Button Has the Class
if ($("input[name='name1']").hasClass("Clicked"))
{
// Button 'name1' has been clicked.
}
else
{
// Button 'name2' has been clicked.
}
});
Hope this helps!
Cheers!
You can create input type="hidden" as holder for a button id information.
<input type="hidden" name="button" id="button">
<input type="submit" onClick="document.form_name.button.value = 1;" value="Do something" name="do_something">
In this case form passes value "1" (id of your button) on submit. This works if onClick occurs before submit (?), what I am not sure if it is always true.
A simple way to distinguish which <button> or <input type="button"...> is pressed, is by checking their 'id':
$("button").click(function() {
var id = $(this).attr('id');
...
});
Here is a sample, that uses this.form to get the correct form the submit is into, and data fields to store the last clicked/focused element. I also wrapped submit code inside a timeout to be sure click events happen before it is executed (some users reported in comments that on Chrome sometimes a click event is fired after a submit).
Works when navigating both with keys and with mouse/fingers without counting on browsers to send a click event on RETURN key (doesn't hurt though), I added an event handler for focus events for buttons and fields.
You might add buttons of type="submit" to the items that save themselves when clicked.
In the demo I set a red border to show the selected item and an alert that shows name and value/label.
Here is the FIDDLE
And here is the (same) code:
Javascript:
$("form").submit(function(e) {
e.preventDefault();
// Use this for rare/buggy cases when click event is sent after submit
setTimeout(function() {
var $this=$(this);
var lastFocus = $this.data("lastFocus");
var $defaultSubmit=null;
if(lastFocus) $defaultSubmit=$(lastFocus);
if(!$defaultSubmit || !$defaultSubmit.is("input[type=submit]")) {
// If for some reason we don't have a submit, find one (the first)
$defaultSubmit=$(this).find("input[type=submit]").first();
}
if($defaultSubmit) {
var submitName=$defaultSubmit.attr("name");
var submitLabel=$defaultSubmit.val();
// Just a demo, set hilite and alert
doSomethingWith($defaultSubmit);
setTimeout(function() {alert("Submitted "+submitName+": '"+submitLabel+"'")},1000);
} else {
// There were no submit in the form
}
}.bind(this),0);
});
$("form input").focus(function() {
$(this.form).data("lastFocus", this);
});
$("form input").click(function() {
$(this.form).data("lastFocus", this);
});
// Just a demo, setting hilite
function doSomethingWith($aSelectedEl) {
$aSelectedEl.css({"border":"4px solid red"});
setTimeout(function() { $aSelectedEl.removeAttr("style"); },1000);
}
DUMMY HTML:
<form>
<input type="text" name="testtextortexttest" value="Whatever you write, sir."/>
<input type="text" name="moretesttextormoretexttest" value="Whatever you write, again, sir."/>
<input type="submit" name="test1" value="Action 1"/>
<input type="submit" name="test2" value="Action 2"/>
<input type="submit" name="test3" value="Action 3"/>
<input type="submit" name="test4" value="Action 4"/>
<input type="submit" name="test5" value="Action 5"/>
</form>
DUMB CSS:
input {display:block}
I write this function that helps me
var PupulateFormData= function (elem) {
var arr = {};
$(elem).find("input[name],select[name],button[name]:focus,input[type='submit']:focus").each(function () {
arr[$(this).attr("name")] = $(this).val();
});
return arr;
};
and then Use
var data= PupulateFormData($("form"));

How can I make a text field for a JavaScript function?

I THINK i have managed to write a script. I just can not make a textfield in HMTL to enter the missing data. It it supposed to receive the keyword from a text field on submit click and navigate to the URL.
I have tried multiple ways of forms and everything. Should have installed VB.net and this would have been done in 5 min.
function urlMaker(keyword) {
var base = "https://www.example.com/list.php?q=";
var ending = "&dhd=1&hdd=low&dtt=list";
var url;
url = base + keyword + ending;
window.location.assign(url);
}
In short words:
I need to know how to create a HTML page with a textfield and a submit button. When I submit it takes the text from the field and run the function and feeds it with the keyword from the textfield. When function has ran it redirects browser.
I'm guessing you have a form like this.
Just attach a submit event-listener to it:
document.querySelector("#search").addEventListener("submit", urlMaker)
function urlMaker(event) {
let keyword = document.querySelector("#keyword").value;
let base = "https://www.example.com/list.php?q=";
let ending = "&dhd=1&hdd=low&dtt=list";
let url;
event.preventDefault();
url = base + keyword + ending;
window.location.href = url;
}
<form id="search">
<input type="text" id="keyword" />
<button type="submit">Search</button>
</form>

TextBox and Button JS Onclick

I have a textbox. I wanted to use a JS onclick to append the input in the textbox to the "btnGO" button as below but it's not working:
document.getElementById('btnGo').onclick = function() {
var search = document.getElementById('dlrNum').value;
window.location.url = "http://consumerlending/app/indirect/dealerComments.aspx?dlrNum=" + search;
}
<input id="dlrNum" type="text" name="dlrNum" autocompletetype="disabled" class="ui-autocomplete-input" autocomplete="off">
<input id="btnGo" type="submit" value="GO" name="GO" runat="server">
What could I be missing?
You had several problems there:
1. Your <input> elements are probably part of a form, so when you click on the submit button - the form will submit, unless you prevent it.
2. You need to use window.location.href (and not .url).
Here is the fix to your code:
document.getElementById('btnGo').onclick = function(e) {
e.preventDefault()
var search = document.getElementById('dlrNum').value;
window.location.href = "http://consumerlending/app/indirect/dealerComments.aspx?dlrNum=" + search;
}
Note the e element inside the function(e) - it's there so we can use the event object to prevent the default behavior of the form submission.
Update window.location.url to window.location:
window.location = "http://consumerlending/app/indirect/dealerComments.aspx?dlrNum=" + search;

HTML Form: How to remember text values of button click?

If you have a form, type some text into it, and press the Enter key, whenever revisiting that form you can double-click on the input box and see the past text submissions.
I have a site that when you press Enter OR click a button, it should take whatever is in the text box and use it for data processing.
This works totally fine when not surrounded by a form but when surrounded by a form an you press the Enter key, it does not act as an enter button push, I believe it's being overridden by the form.
My goal is to have the user be able to press the Enter key as well as click the button to submit the data, but to also remember the text values that were in the text box regardless of which way you submitted the data.
What I have:
<input type="text" id="username-field" class="form-control" placeholder="username">
<input class="btn btn-default" type="button" id="get-name" value="Get Name">
Javascript
$("#get-name").click(function() {
var name = $("#username-field").val();
// ... call other function with name ...
});
$("#get-name").keydown(function(e) {
if (e.which == 13) {
var name = $("#username-field").val();
// ... call other function with name ...
}
");
What I would like to use:
<form>
<input type="text" id="username-field" class="form-control" placeholder="username">
</form>
I tried doing e.preventDefault() when the Enter key is pressed, but this does not remember the text in the input field.
I also considered doing a small cache type thing but am unsure of how I'd go about this.
Any help would be much appreciated!
Thanks!
Doesn't use form at all. Just, why you added it, if you don't use it as intended?
You either mistyped provided code copy-paste, or have errors in yours script (the $("#get-name").val() mistake).
If you want to prevent form from submission, you should e.preventDefault()-it in submission handler, and return false from it:
$('#form-id').submit(function (e) {
e.preventDefault();
// do smth. else here
...
return false;
})
Saving/retriving data with localStorage for HTML5-supporting browsers:
$(function () {
$('form input[type=text]').doubleclick(function () {
var id = $(this).attr("id");
value = localStorage.getItem("form_xxx_" + id);
// do smth. with cached value, ie:
if (value != "")
$(this).val(value); // put in textfield
});
});
$('form').submit(function (e) {
$('form input[type=text]').each(function () {
var id = $(this).attr("id");
localStorage.setItem("form_xxx_" + id, $(this).val());
});
...
// all other work
});
Note: make sure you don't put some user's personal data in browser's local storage -_-

Pressing 'enter' on a input type="text", how?

I am facing a problem I can not solve JQuery Javascript. Can you help me and help me understand.First here is my code :
(...)
<script type="text/javascript">
// Autocomplete suggestions
$(function () {
$("#autoCompInput").autocomplete({
source: "/Suggestions",
minLength: 3,
select: function (event, ui) {
if (ui.item) {
$("#autoCompInput").val(ui.item.value);

// Provide search results
$(function () {
$("#autoCompSearch").click(function () {
var searchParameters = $("#autoCompInput").val();
var jsonData = JSON.stringify(searchParameters, null, 2);
window.location = "/Search?criteria=" + searchParameters;
});
});

<input class="ui-autocomplete-input" id="autoCompInput" role="textbox" aria-haspopup="true" size="50" autocomplete="off" aria-autocomplete="list" value = "#ViewBag.SearchInfo"/>
<a id= "autoCompSearch" href = "#" ><img src="#Url.Content("~/Content/Menu/Images/magnifier.png")" alt="Search" /></a>

With this code I can't use the 'Enter' key to execute my search. When the user is in the input autoCompInput I would like to be able to detect if he press 'enter' and launch the submit. I read I must add a onkeyup="onKeyPressed(event)" event but I don't understand how to write the javascipt associated with the command. I tried but without success... Do you have a solution for me?
Thank you,
You should bind the keypress event to your input
$("#autoCompInput").bind("keypress", {}, keypressInBox);
function keypressInBox(e) {
var code = (e.keyCode ? e.keyCode : e.which);
if (code == 13) { //Enter keycode
e.preventDefault();
$("yourFormId").submit();
}
};
With similar HTML:
<input type="text" id="myTxt" />
<input type="submit" id="mySubmit" />
This script (which uses the latest jQuery 1.7.2) should do it:
$('#mySubmit').click(function() {
alert('Submitted!');
return false;
});
$('#myTxt').on('keyup', function(e) {
if (e.keyCode === 13) {
$('#mySubmit').click();
}
});
Here's a working example.
To assign a keyup event in jquery
$("#autoCompInput").keyup(function(event) {
if (event.keyCode==13) {
alert('enter key');
}
});
I think there is a better and more standard solution to this type of problem.
you can have a GET form around those inputs and whenever you press enter on any input inside that form, it will be submitted to whatever is in the action attribute of the form. This is how it would look like (I took your code but I am removing the bits irrelevant for my answer):
<form id="idForJqueryOnly" action="/Search" method="GET">
<input type="text" name="criteria" value="someuserinput"/>
<button type="submit"><img src="...")" alt="Search" /></button>
</form>
This is standard browser behaviour. So, what the form does? when submitted the browser creates a URL like this:
http://yourserverguesedfromthecurrenturl/Search?criteria=someuserinput
What happened is that the browser took all the inputs with name and value (and not disabled) from the form and serialized them into url form.
Now, the submit event can be triggered by pressing enter on any of the inputs inside, including buttons as long as the buttons don't have the attribute type="button".
If you wanted to do more things with the data with javascript before going to the search page, you can do this with jquery:
$("#idForJqueryOnly").submit(function(){
// here you can do stuff like serialize the form, or sanitize the input of tue user.
var data = $("#idForJqueryOnly").serialize();
$("[name=criteria]").val($("[name=criteria]").val().customSanitizeMethod());
// if you return false, the form will not submit, say, for validation errors:
return customValidator.isFormValid("#idForJqueryOnly");
})
