I have a problem with the following code in an ASPX page:
<script type="text/javascript">
$(document).ready(function() {
$('.test').click(function() {
alert("click")
})
});
</script>
<asp:CheckBox runat="server" Text="Checkbox XYZ" CssClass="test" ID="cb1" />
In the browser (FF3.5 / IE8) I have the following problem:
I guess this has to do with the way the checkbox is rendered to HTML, which is like this:
<span class="test">
<input id="ctl00_c1_cb1" type="checkbox" name="ctl00$c1$cb1" checked="checked"/>
<label for="ctl00_c1_cb1">Checkbox XYZ</label>
</span>
How do I correctly setup the click event handler to prevent it from being called twice?
I have just experienced the same thing, but am not sure that event bubbling is causing my issue. I have a custom tree control, and when an item is opened, I use $(id).click()
to attach a handler to all elements of a certain kind.
I suspect that this means that existing items elsewhere that already have the event, may then have it added again. I found that unbinding everything then re-binding solved my problem, thus:
$('img.load_expand').unbind("click").click(function()
{
// handler
});
