For example:
<input id="#me" type="button" callme="doAction()"/>
<script>
var result = callFunction( $("#me").attr('callme') ); /// ?????????

What do your callFunction does? Are you expecting to pass a string?fcalderan– fcalderan2010-10-11 13:05:38 +00:00Commented Oct 11, 2010 at 13:05

Try this:
<script>
var callMe = $("#me").attr("callme");
var result = eval(callMe);
</script>

A better solution would be to not include the function in your HTML markup. It is almost always better to separate your markup from your scripting.
Instead consider adding it to your dom object using
$('#me').data('callme', function(){...});
or
$('#me').data('callme', doAction);
and calling it using
$('#me').data('callme')()
or a little safer
($('#me').data('callme')||jQuery.noop)()
See the jQuery documentation for more details on the data function.

I get this error: (f||jQuery.noop)(); f is not a function ?? the function exists...
Mottie
jQuery.noop() is in jQuery version 1.4+
tKe
jQuery.noop can be replaced with function(){} if you need to or you could assign it yourself somewhere with jQuery.noop = function(){};If the attribute callme is the name (identifier) of a function just use
<input id="#me" type="button" callme="doAction"/>
(window[$("#me").attr('callme')] || function() {})();
so you can avoid using an expensive eval().

I like this but, I get this error: (f)(); f is not a function ?? the function exists...
I think maybe this is the solution:
<script>
setTimeout( $("#me").attr('callme'), 0 );
</script>
But how to get the returned value??
