set focus() on textbox on form onload - javascript

I am trying to set focus on a textbox in a form that's a part of jQuery tree. Here is my code
$(document).ready(function() {
$("#search").focus();
});
HTML:
<div>
<form action="search" method="post" name="frmSearch>
<label for="search">Search:</label>
<input type="text" name="search" id="search" />
<input type="submit" name="button" value="Search" />
</form>
</div>
When I click on Search tab in the tree, it won't set focus on the textbox. Can someone let me know what's wrong in the code?

You're focusing the textbox on page load, however as soon as you click anywhere else on the page (such as a tab), the focus will be removed from the textbox and given to whatever you just clicked.
Instead of focusing on page load, attach a click listener to your tab so that when it is clicked the search textbox gets focus. Since I haven't seen all your markup, I'm using #mySearchTab as a placeholder for the ID of your search tab:
$(document).ready(function() {
$("#mySearchTab").on('click', function() {
$('#search').focus();
});
});
Also, don't forget to close your functions with a ).
I'm not sure what your tree looks like but here's a working demo using jQuery tabs.

try following:
$(function(){
$("input:first:text").focus();
});
working fiddle here: http://jsfiddle.net/8CTqN/2/
tested on chrome

I made some modification in your js codes
http://jsfiddle.net/8CTqN/5
$(document).ready(function(){
$(function(){
$("#search2").focus();
});
});

how do i trigger a button with the enter key in java script?/ how to give text box and search button an ID?

Sorry i know this question has been asked and answered before but i can't seem to implement it into my code. very new to programming and struggling quite a bit.
Pretty simple stuff here i have a search bar and a search button. What i am trying to do is instead of having to physically click the search button to search for what i want, i would like to have the ability to be able to click the enter key which could search as well. Here is the code for the search bar and button.
Easy stuff.
<div class="ui-widget"> <!-- only for css purposes-->
<input id="search"> <!-- for the search box-->
<button type="button" onclick="searchresult()">Search</button> <!-- search button-->
</div>
So at the moment when you click the search button it will activate the javascript function i have which is:
function searchresult() {
//find the result
}
which in turn will find the result you want. deadly stuff.
I haven't included the code which is inside the javascript function as we don't need it for this question and its quite lengthy.
so basically i want the enter key to be able to activate the searchresult javascript function the same way the search button does.
I am aware that you can use jQuery keypress() Method to do this. and here is the code which can be used to do what i am wondering but i just don't know how to implement it into what i have:
$("#id_of_textbox").keyup(function(event){
if(event.keyCode == 13){
$("#id_of_button").click();
}
});
I am aware of the id attribute which is used in HTML coding as well but i don't know how i would go about correctly assigning the search button and text box an id each which then i could use in the code i have just above which then in turn would allow me to use the enter key as search as well.
So if anyone could just show me how i could use the jQuery code i found to solve my question that would be brilliant. Completely open to any other suggestions about how i would go about it either.
Thank you everyone for your time and attention!
Use the following code (explanation below):
function searchresult() {
console.log('searching');
//find the result
}
$("#search").keyup(function(event) {
if (event.keyCode == 13) {
$("#searchButton").click();
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="ui-widget">
<input id="search">
<button type="button" id="searchButton" onclick="searchresult()">Search</button>
</div>
What this does is it will hook up an event to the input box with the id search and whenver it receives a keyup (key release) event, it will check if it is the Enter key and, if so, fire the click event of the button with id searchButton (I added that id as an example). Your search button's click event is hooked up to the searchResult() function, which is in turn called from that.
If you need more information on how event handling works in jQuery, check out jQuery's Handling Events page.
You really should consider using a form.
function search_function(search_terms){
// Do your search action here
alert(search_terms);
};
$(function(){
$("#search").on("submit", function(e){
search_function($("#search_terms").val());
e.preventDefault(); // Prevents submitting in most browsers
return false; // Prevents submitting in some other browsers
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id='search'>
<input type='text' id='search_terms' placeholder='Search' />
<button>Search</button>
</form>
Or here is an example in pure JS
function search_function(search_terms){
// Do your search action here
alert(search_terms);
};
document.addEventListener("DOMContentLoaded", function(){
document.getElementById("search")
.addEventListener("submit", function(e){
search_function(document.getElementById("search_terms").value);
e.preventDefault(); // Prevents submitting in most browsers
return false; // Prevents submitting in some other browsers
});
}, false);
<form id='search'>
<input type='text' id='search_terms' placeholder='Search' />
<button>Search</button>
</form>
You can assign the id to your search button :
<button type="button" onclick="searchresult()" id="search_key">Search</button>
Then you can trigger the click action on button using jQuery#trigger
JS :
$("#id_of_textbox").keyup(function(event) {
if (event.keyCode == 13) {
$("#search_key").trigger('click');
}
})
$('#search").change(function() {
searchResult();
});
Don't even bother with looking for the "enter" key; just watch for the input value to change (which would happen upon pressing enter, or blurring the field).
You can use a form and it's onsubmit event since you want enter key and submit click to do the same thing.
<form action="" method="" onsubmit="searchresult(this);">
<input type="text" name="query" />
<input type="submit" value="Search" />
</form>
But don't forget to use event.preventDefault() or return false.

Input text box focus on blur event

Actually I'm trying to set focus on text-box when focus is lost.The reason behind this is that there is requirement to forcefully set focus on text-box if some validation fails(like empty field validation) and validation is perform on blur event of that text box.
I have tried it on fiddle also but it seems like focus is there but cursor is not blinking.
Please refer link : http://jsfiddle.net/zHeJY/
Please let me know the reason behind this and solution for same.
Thanks in advance.
First: This is a bad idea to trap user inside an input unless validation passes! Users should be allowed to focus whatever they want. Ideally, you can prevent a form submission if validation fails.
Problem: (1) You don't have any other element in the fiddle you provided. (2) You are not validating anything, just doing an endless loop for blur-focus cycle!
Solution:
See this fiddle: http://jsfiddle.net/zHeJY/7/
With a proper validation routine in place (and another element available), it will work.
HTML:
<input id="setFocus"/>
<input id="other" />
JS:
$("#setFocus").on("blur", function(e) {
if (! validate(this)) {
$(this).focus();
}
});
<html>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.10.2.min.js">
</script>
<script type="text/javascript">
$( document ).ready(function() {
$(document).on('blur', "#setFocus", function (e) {
$(this).focus();
});
});
</script>
</head>
<body>
<input type="text" id="setFocus"/>
<input type="text" id="set"/>
</body>
</html>
try this
HTML
<div id="something">
<input type="text" id="setFocus"/>
<input type="text" id="setFocus1"/>
</div>
JS
$("#something").mouseup("blur",function(){
$(this).children(":first").focus();
})
you should have parent element for this on click of any where you will get the required result

Pressing Enter/Return key doesn't trigger button click in Safari

I have a structure of the following format , which I display in a Bootstrap modal.
<div>
<input type="text"/>
<input type="text"/>
<button class="jSomeButton" onclick="javascript: return false;"></button>
<!--Click event handled in Javascript code-->
</div>
$(function(){
$(".jSomeButton").on('click',function(){
//Called from Firefox, Chrome and IE
//Not called from Safari
});
});
In Firefox, Chrome and IE when I press Enter/Return key after filling the inputs, the button click is triggered.
But in Safari [v4.0.3] , it doesn't trigger the button click! Rather it seems to postback to the same page.
Is this a known issue in Safari?
If yes, any workaround?
If no, could someone please help me with figuring out the root problem?
P.S. :
1. I'm familiar with the Javascript code for triggering button click on Enter keypress event. Just curious as to why the above won't work only in Safari.
2.Just for clarification, pressing Enter key while I'm still on the input control and not by pressing tab to first focus on the button and then press Enter.
Add the input fields and buttons to a form.
try using this but i m not sure about this is the right way to do it.
in that case you better add two js listener functions to the input fields. as
`
<div>
<input id="one" type="text"/>
<input id="two" type="text"/>
<button class="jSomeButton" onclick="javascript: return false;"> </button>
<!--Click event handled in Javascript code-->
</div>
$('#one').keypress(function(e){
if(e.which == 13) {
//call your code
}
});
$('#two').keypress(function(e){
if(e.which == 13) {
///call your code
}
});
better you write three listeners one for button other two for two input files. hope this ill help you. i am not sure about this solution. please let me know after trying it.
Instead of class attribute use id attribute onclick event ,
<div>
<input type="text"/>
<input type="text"/>
<button class="jSomeButton" id="jSomeButton" onclick="javascript: return false;"></button>
<!--Click event handled in Javascript code-->
</div>
$(function(){
$("#jSomeButton").on('click',function(){
//Called from Firefox, Chrome and IE
//Not called from Safari
});
});
if you do not want to add ID you can delegate event to the document so event will work on DOM which has defined class.
Example
<script type="text/javascript">
$(function(){
$(document).on('click', ".jSomeButton" ,function(){
alert('works');
});
});
</script>
#Vandesh,
As posted in comments, I suggest you put up a form tag around your entire form.
Have a look at this JSFiddle for more idea.
http://jsfiddle.net/JUryD/
I tried this on Safari, Chrome, IE6+, Opera and Firefox 22+
Let me know if you face any other troubles.
Here is the code:
<div>
<form>
<input type="text"/>
<input type="text"/>
<button class="jSomeButton" onclick="javascript: return false;">Send</button>
</form>
</div>

How to select the content inside a textbox when loading the page?

I'm working on an application, and I want a text field to be selected when the page is loading so that when a user uses Ctrl + v it paste the content inside the textbox. Any one knows how to do that?
the text field is
<div>
<input wicket:id="email-address" type="text" id="textbox-email" />
</div>
Thanks!
3p3r answer is of course perfectly right. If you want this to be reusable and contolled via wicket, than please check the wicket wiki page.
You can use HTML5's autofocus attribute:
<input type="text" autofocus />
Works of course for just one field.
you should set focus to your input:
document.forms['your_form'].elements['your_textbox'].focus();
For your example above:
document.getElementById('textbox-email').focus()
After it gained focus, you should select it:
either add this onfocus attribute to your inputs (better)
<input type="text" onfocus="this.select()" />
Or use this jQuery snippet (best):
$(document).ready(function() {
$("#textbox-email").focus(function() { $(this).select(); } );
});
Pure Javascript:
var element = document.getElementById('textbox-email');
element.onfocus = function() {element.select();}
document.getElementById('textbox-email').focus();
Add the whole thing to window.onload or onload attribute of body tag.

when i click on this textbox it gets big but when i click away how do i make it go back to normal?

i'm basically mimicking the share button feature on facebook with jquery and what im trying to do is when i click on the textbox area the textbox gets larger by height. and when i click away it should get back to normal. with the last piece of jquery the code doesnt work at all. what are my options in getting this to work?
thanks.
ps:
i know most of this can be done with css but i'm experimenting with jquery to better learn it. :)
here is my jquery.
$(function() {
$('input[name=search]').click(function() {
$(this).addClass('txthover');
});
$('body').click(function() {
$('input[name=search]').removeClass('txthover');
});
});
the html
<div id="box">
<div id="search">
<input type="text" name="search" /><input type="button" name="btnsearch" value="search" />
</div>
</div>
The proper way to do it would be to use the focus and blur events of the element:
$('input[name=search]').focus(function() {
$(this).addClass('txthover');
}).blur(function() {
$(this).removeClass('txthover');
});
Here is a quick example.
