SO I have a form that look similar to
<form action="test.php" id="checksub" method="post">
<div>
<select name="mydropdown">
<option value="buy">buy</option>
<option value="sell">sell</option>
</select>
</div>
autocomplete text input that triggers "checksub"
<input type="submit" id="checksub" name="checksub" style="visibility:hidden">
<input type="submit" id="newsbutton" name="newsbutton">
</form>
<script type="text/javascript">
$('#newbutton').click(function() {
var newaction = "cantfinditems.php";
$("#checksub").prop("action", newaction);
$('#checksub').submit();
});
</script>
Now the submit button is hidden because the autocomplete triggers it anyway, but if the user cant find what they are looking for I want a button that says "cant find what your'e looking for?"
I want this button to have a different action to the form action, ie window.location = cantfinditems.php
but I also want to carry the POST data from the form ie "mydropdown".
Thank you
Ok, so you need a second button, which calls a JavaScript function. In this function, you do a number of things:
Set the action attribute of the form to your alternate action (e.g. cantfinditems.php)
var newaction = "cantfinditems.php";
$("#form_id").prop("action", newaction);
Submit the form
$('#form_id').submit();
So a full example would be:
<script type="text/javascript">
$('#yourbuttonid').click(function() {
var newaction = "cantfinditems.php";
$("#form_id").prop("action", newaction);
$('#form_id').submit();
});
</script>

My code
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<form>
<button id="test" value="123" name="test" >ok</button>
</form>
<script>
$(document).ready(function () {
$("#test").click(function() {
var combinedData = $("#test").serialize();
$.post(
"element_submit.php",
combinedData
).done(function(data) {
//alert("Successfully submitted!");
$("#result").html(data);
}).fail(function () {
//alert("Error submitting forms!");
})
});
});
</script>
<div id="result" ></div>
The element_submit.php file
<?php
//just to test it should output in the #result div
echo $_POST['test'];
?>
What I am trying to do is submit the with the value="attribute" so the data is serialized and send the post request, it's not like a submit when user insert a value and submit,What I need is to get the value attribute and submit to the php, this code is only for To simplify and illustrate what I am trying to do, because in this page I have the following buttons with ids #follow #unfollow so I need a way to get the button value to make the user follow and unfollow.
you need to serialize the form - not the elements within it .You can also have the triggering button outside the form which will prevent hte form from submitting on the button click.
<form id="testForm">
<input type="hidden" name="testInput" value="123"/>
</form>
<button name="test" id="testButton">submit</button>
...
<script>
$(document).ready(function () {
$("#testButton").click(function() {
var combinedData = $("#testForm").serialize();...
$(document).ready(function () {
$("#testButton").click(function() {
var combinedData = $("#testForm").serialize();
console.log(combinedData);
})
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="testForm">
<input type="hidden" value="123" name="testinput"/>
</form>
<button id="testButton">Click</button>
Straight JS might help you out. Include a function that sends the id and get the value of that id. Then just send a regular post of the value without serialize... easier.
<script>
function fetchButtonValue(theId){
var p = document.getElementById(theId).value;
alert (p);
}
</script>
<button id="myFormBtn" value ="woo"
onclick="fetchButtonValue(this.id)">My Button</button>
this works...
You could also put a class on the button let's say class="followBTN" then on a click you could just snag the value by $(this).val() I'd use this method if I had more than one button per page.
So I have a form that I am submitting and the valueof the input button is "View Insight." When I submit the form using Request, I get a nasty string in the URL like Insight=View+Insight.
What I want it to say in the URL is "Insight=Confirmed". I tried using jquery to change the value of the button and it worked but you see it changing the value in the user interface. How do I change the value of what I want without showing the user?
Here is what I have so far:
JQUERY
<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#savebtn").bind("click",function(){
$(this).val('confirmed');
});
});
</script>
HTML
<form action="confirm4.php" method="request">
<input type="submit" name="insights" id="savebtn" value="View Insights" />
</form>
You can change the input[type=submit] to button[type=submit] like so:
<form action="confirm4.php" method="request">
<input type="hidden" name="Insight" value="Confirmed">
<button type="submit" id="savebtn">View Insights</button>
</form>
First, .bind is deprecated and you should be using .on instead.
Second, what you are looking for is
$("#savebtn").on("click",function(e){
e.preventDefault(); //stop current submission
var $this = $(this);
$this.val('confirmed'); //change the value
$this.off("click"); //unbind the handler
$this.click(); //click the button again
});
I'm new to Javascript and HTML.
I have the following form in HTML:
<div id="form-select">
<form id="date_form" onsubmit="return myFunction();">
<datalist id="dates">
<option value="February 7">February 7</option>
<option value="February 14">February 14</option>
<option value="February 21">February 21</option>
<option value="February 28">February 28</option>
</datalist>
<input type="text" class="input" name="data" id="date" value="" list="dates" placeholder="pick a date"><br>
<input type="submit">
</form>
</div>
Here's the javascript in a file called script.js. The js file is linked in the header as <script type="text/javascript" src="script.js" />:
function myFunction(){
var input = document.getElementById("date").value;
if(input==="February 7"){
document.getElementById('w1').innerHTML = document.getElementById('w1').innerHTML + "<h2> HEADING </h2>";
}
return false;
};
When I fill out the form and hit submit, the javascript correctly executes the function and adds "HEADING." However, when I press submit again, it adds "HEADING" a second time under the first instance of it.
How do I make it so that the page "refreshes" each time submit is pressed?
Thanks!
You can Use
window.location.reload();
In your Submit event code..
use jQuery, bind('submit', function(e){ e.preventDefault; ....; })
$('#date_form').submit(function(e){
e.preventDefault();
var input = document.getElementById("date").value;
if(input==="February 7"){
document.getElementById('w1').innerHTML = "<h2> HEADING </h2>";
}
return false;
});
Found another way around the issue. I added the statement:
document.getElementById('week').innerHTML = "";
at the beginning of each call of the function. That way, every time the user clicks submit, the div is emptied out before it is repopulated.
My form will not submit through AJAX to show the return of the PHP page, 'myscript.php'.
This is the HTML I'm using:
<form name="myform" id="myform" method="post" action="#" enctype="multipart/form-data" accept-charset="utf-8" class="taxonomy-drilldown-dropdowns">
<ul>
<li>
<label>Destination:</label>
<select name="city" id="city">
<option class="level-0" value="atlanta">Atlanta</option>
<option class="level-0" value="miami">Miami</option>
</select>
</li>
</ul>
<input class="srch_btn" type="button" value="{{submit-text}}" />
</form>
Here is the javascript earlier in the page:
jQuery(document).ready(function($) {
$('#city').change(function() {
$(this).parents("form").submit();
});
$('#myform').submit(function() {
$.post(
'myscript.php',
$(this).serialize(),
function(data){
$("#mydiv").html(data)
}
);
return false;
});
});
Here is the myscript.php:
<?php
if ($_POST['city'] == "atlanta") {
echo "Div contents 1";
}
if ($_POST['city'] == "miami") {
echo "Div contents 2";
}
?>
The submit button won't respond at this point or make an attempt to access the 'myscript.php' file. Help is appreciated. Thanks in advance!
It is better to use .closest() rather than .parents() in this case.. As parents selector gets all the ancestors that match the selector.
$('#city').change(function() {
$(this).closest("form").submit();
});
And to stop the Default action use e.preventDefault instead of return false
$('#myform').submit(function(e) {
e.preventDefault();
// Your code here
});
In you HTML code, I think you should change input type=button to input type=submit
<input class="srch_btn" type="submit" value="{{submit-text}}" />
Then when you click that button, the form will be submitted to your php page.
Also, about select change event in your jQuery code, I think you can just try following selector, as you have the name/id attribute available in your HTML.
$('#city').change(function() {
$('#myform').submit();
});
One issue with your code is that it does not actually stop the form from being submitted. return false; does not exactly work in jQuery in the way that you think it does. Instead, to stop the default action, you would have to do something like this.
$('#myform').submit(function(event) {
event.preventDefault();
http://api.jquery.com/event.preventDefault/
On top of that, if you don't want the form submit to take place, and you want to replace it with your own AJAX submition, why are you calling form submit at all in this code? Why not just put the AJAX directly into your change code?
dqhendricks was right - why use form submit when you can just access ajax directly? In the below example, I added a div (#responder) below the form to show the output. Try it -- you'll see that it works perfectly.
You really don't need the button, although I left it there, because the data is sent/received the moment the drop-down is changed. You will see your messages appear in the div I included below the form.
REVISED HTML:

REVISED JAVASCRIPT/JQUERY:
$(document).ready(function() {

I would like to have a form that can submit to two different action pages based on a select box.
Meaning if I select in the select box Products, the action would be products.html, and if I select Users, the action would be users.html
I have found many examples that have two submit buttons, but I need only one submit button.
Any ideas on how to do it?
you can use jQuery for that ...
if selected value equals something
set form attribute action to the other thing not initial action
this is pseudo code of course ..
here is a working solution :
<html>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.4.2.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#selectList").change(function(){
if($('#selectList').val() == 1){
$("#yourform").attr("action","secondaryaction");
}
});
});
</script>
</head>
<body>
<select name="dummy" id="selectList">
<option value="0">foo</option>
<option value="1">bar</option>
</select>
<form id="yourform" action="primaryaction">
bla bla
</form>
</body>
</html>
Try something like this (assuming a form named "myForm"):
document.myForm.onsubmit = function() {
if (this.mySelector.value == 'products') {
this.action = 'products.html';
}
// the "else" isn't necessary: leave it at "users.html" as a default.
};
read about new attributes
Attributes for form submission that may be specified on submit buttons. The attributes are: formaction, formenctype, formmethod, formnovalidate, and formtarget
Works in IE >= 11
my example for will be demonstrated point :
<form action="1.php">
<input type="text" >
<button value="go"> GOOOOOOOOOOOO</button>
<button value="go" formaction="2.php"> DONNNNNNNNNNNNNNNNOOOO</button>
</form>
if(condition==products)
document.forms[0].action = 'products.html;
else
document.forms[0].action = 'users.html;
