The setting is easy; I want to be able to add a class to (in this case) a button when onClick-event is fired. My problem is that I haven't found a way to pass the button itself as the parameter to the function. I'd like to do something like:
<asp:Button ID="Button" runat="server" onclick="addClassByClick(this)"/>
And then a javaScript function something like this:
function addClassByClick(button){
button.addClass("active")
}
I know I've got a lot of errors here, but that's why I'm posting. I've tried different scenarios with jQuery and without jQuery but I always end up with a broken solution (clicks suddenly stop coming through, class not added etc etc) so I decided to ask the pro's.
Any suggestion to what I can try? Thanks for reading editand all the help!
This question is related to
javascript
asp.net
jquery
It needs to be a jQuery element to use .addClass(), so it needs to be wrapped in $() like this:
function addClassByClick(button){
$(button).addClass("active")
}
A better overall solution would be unobtrusive script, for example:
<asp:Button ID="Button" runat="server" class="clickable"/>
Then in jquery:
$(function() { //run when the DOM is ready
$(".clickable").click(function() { //use a class, since your ID gets mangled
$(this).addClass("active"); //add the class to the clicked element
});
});
$(document).ready(function() {
$('#Button').click(function() {
$(this).addClass('active');
});
});
should do the trick. unless you're loading the button with ajax. In which case you could do:
$('#Button').live('click', function() {...
Also remember not to use the same id more than once in your html code.
Try to make your css more specific so that the new (green) style is more specific than the previous one, so that it worked for me!
For example, you might use in css:
button:active {/*your style here*/}
Instead of (probably not working):
.active {/*style*/} (.active is not a pseudo-class)
Hope it helps!
$('#button').click(function(){
$(this).addClass('active');
});
Using jQuery:
$('#Button').click(function(){
$(this).addClass("active");
});
This way, you don't have to pollute your HTML markup with onclick handlers.
