How to dynamically change the onclick handler
|

More related to just web development in general, but sometimes you might need to change the onclick event handler of an element. This can be a little tricky, but I find the best way to do this is:br /br /blockquotebr /element.onclick = function() {this_is_my_function($param)}br //blockquotebr /br /The tricky part is that the value of the onclick is a span style="font-weight:bold;"reference/span to the function and not the function itself. So if you simply put:br /br /blockquoteelement.onclick = this_is_my_function($param)/blockquotebr /br /It would actually fail. You need to wrap this under another function, hence the original code where the function() calls the this_is_my_function().
