jQuery Click event on asp:button - asp.net

Question

I have a server side button as
<asp:Button ID="btnSummary" runat="server" OnClick="btnSummary_Click" Text="Next" />
I want to attach the jQuery Click event using its ID and NOT using the alternative class attribute way.
I tried to attach the click event as:
$("#btnSummary").click(function()
{
alert("1");
});
But, its click event is not fired. Also, I have also tried $("id[$btnSummary]").
Is there any way to attach the click event on asp:button using jQuery without the class attribute on the button?

Answer 1

Some of the options you have can be found here
How to stop ASP.NET from changing ids in order to use jQuery
EDIT:
After reading your comments on other answers, it sounds like you need to bind the onclick event handler inside of ASP.NET AJAX's pageLoad, so that it is bound on every postback, including asynchronous postbacks. On the other hand, $(document).ready() binds only once on initial page load
function pageLoad(sender, args)
{
$("#<%=btnSummary.ClientID %>").click(function()
{
alert("1");
});
}
Dave Ward wrote a nice article on the difference between pageLoad and $(document).ready().

Answer 2

Add ClientIDMode="Static" to your asp:button, something like this:
<asp:Button ID="Button1" runat="server" ClientIDMode="Static" Text="Button" />
This will make the ID remain the same. It disables the autogenerated names for this control.
Here is the reference for this: http://msdn.microsoft.com/en-us/library/system.web.ui.control.clientid.aspx

Answer 3

Check if the id attribute is in the html source when you run the site.
Do you have the click function inside a document ready function ?
-
$(document).ready(function() {
// put all your jQuery goodness in here.
});
EDIT:
Since its a server side control and the ID changes, you will need to dynamically update the javascript on every page load with the variable.

Answer 4

ASP.NET generates a UniqueID for client-side stuff, you can use that to bind the event. That ID is generated based on the position of that Control inside a ControlCollection and different INamingContainers, it's ugly and you can't guess it...
Add this kind of code somewhere on your page to hook up that button.
<script type="text/javascript">
$(function() { $("#<%=btnSummary.ClientID%>") }).click(function(){/*...*/});
</script>

Answer 5

I'm little confused here now.
Let me explain:
1. I added a button on the page:
<form id="form1" runat="server">
<div>
<asp:Button ID="Button1" runat="server" Text="Button" />
<div>
2. Then I added a JavaScript and jQuery:
<script type="text/javascript">
$(document).ready(function() {
$("#Button1").click(function() {
alert("Hello world!");
});
});
</script>
3. The generated html is this:
<div>
<input type="submit" name="Button1" value="Button" id="Button1" />
<div>
Now, I don't see ASP.NET (asp.net 3.5) changing the ids. Why do I see
different behavior?
Btw. This does work when I hit the button!
Thanks.

Answer 6

Assigning the selector to the class worked for me.
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="My Button" CssClass="myButton"/>
<script>
jQuery(".myButton").click(function () {
alert("clicked");
});
</script>

Answer 7

Please use the following syntax : $("[id*=Button1]") to reference any asp control

Answer 8

use pageLoad when using updatepanels because document.ready only runs once on initialization of the page and loses its binding on partial postbacks.
PageLoad gets run everytime so will rebind every partial postback.

Answer 9

I had the same problem, this works for me
<asp:Button ID="Button1" runat="server" Text="ASP Button" OnClientClick="return false;" />
Its the addition of return false that seems to make the difference. Hope this helps.

Answer 10

ASP.NET adds to you id (example: id "selectButton" becomes
"ctl00_middleContent_gvPeople_ctl04_selectButton");
Use the jquery syntax to search for the part of the id that doesn't change.
$("[id='_selectButton']")

Answer 11

Please try below:
document.getElementById("<%=button1.ClientID %>").click();

Answer 12

Wrap this <asp:Button/> inside a html <div> container.
<div id="testG">
<asp:Button ID="btn1" runat="server" Text="TestButton" />
</div>
$(document).ready(function () {
$("#testG").click(function () {
alert("1");
//your code
});
});

Answer 13

You have reached there. There are two ways i guess,
Either inspect the control from Browser and See the Control ID, looks like ct1000_ btnSummary. use this ID on Click event of jQuery.
replace code
$("#ctl00_contentplcedholder_btnSummary").click(function()
{
alert("1");
});
Next one is quite easy just add an attribute ClientIdMode="static" to your control and use your actual Jquery click event it will fire.
