I have a button with an onclick callback that creates a closure and
uses Element.observe to clear the old callback and set the closure as
the new one. Here's the pseudo code:
<button onclick='original_handler.bind(this)(event)'>button</button>
function original_handler(event) {
//do some stuff on the first click
//now clear the original handler and set the new one
this.writeAttribute({onclick:null});
//create the newCallback
function newCallback(event) {
//do some new stuff when we click the second time
}
this.observe('click',newCallback);
}
Everything works fine in firefox and chrome but in IE8 when the new
callback
is set IE8 actually calls the function and messes everything up. So
instead of
click->call original_handler->set newCallback what I get is
click->call original_handler->set newCallback->call newCallback which
is not
what I want at all. Any advice on how to fix the situation.
