Question

I need to call a jQuery function with EVAL (but I don’t know how to do it), then I solve with this solution, but I don’t think that this is the correct way…

<script>
jQuery.fn.customfunction = function (data) { alert( data ); }
</script>

<div id="eval_div"></div>
<form><input role="button" myFunction="customfunction"/></form>
<script>
$('[role=button]').click( function() {
var button = this;
$.post( "/action",
        $(form).serialize(),
        function (data) {
            $('#eval_div').html( "<script>" + $(button).attr('myFunction')  + "('" +  data   + "');</script>" );
        } );
});
</script>

customfunction is a general function for each form, each form has a different CUSTOMFUNCTION with different name, by this reason, the button has the name of the function.

If you just want to call the function… you can do it very simply:

function (data) {
    jQuery.fn[$(button).attr('myFunction')](data);
};
