  • AS3 - Can I know if a class implements an interface (or is a subclass of another class) ?

    - by lk
    With this code function someFunction(classParam:Class):Boolean { // how to know if classParam implements some interface? } i.e. Comparing classParam with IEventDispatcher interface: someFunction(EventDispatcher) // returns true someFunction(Object) // returns false I know it can't be done with is operator. But, is there a way to do it? Is there a way to know if a class implements some interface? (or is a subclass of another class?)

  • IE is doing strange things with JQuery

    - by Syncopated
    So ... The thing is, the code works in FireFox, no problems. But when I open the same page, it gives me the following error: "Undefined is null or not an object." But when I copy the code to a localhost page, it works fine. Also when I clear my cache in IE it works, but only once, if I refresh after that one load, it gives me the same error. Here is the code: <script type="text/javascript" src="datepicker/js/jquery-1.4.2.min.js"></script> <script type="text/javascript"> var count3 = 0; var count5 = 0; var count2 = 0; var count4 = 0; $(document).ready(function(){ $('#switch3').click(function(){ $('#switchDiv3').slideToggle(350); if(count3 == 0){ count3 = 1; document.getElementById('switchImage3').src = "images/ArrowDown.png"; return; } else { count3 = 0; document.getElementById('switchImage3').src = "images/ArrowRight.png"; return; } }); ... (this is the code for each item that is generated) </script> And the code that determines the div that should hide: <table width="100%" border="0" cellspacing="0" cellpadding="0" align="center"> <tr> <td width="20" align="center" valign="top" style="padding-right: 3px"> <a style="cursor: pointer;" id="switch3"><img width="20" height="20" src="images/ArrowRight.png" id="switchImage3" style="border-style: solid; border-width: 1px; border-color: black;"/></a> </td> <td> <div id="switchDiv3"> <div align="left"> (Contents of the div here) </div> </div> </td> </tr> </table> Any help is appreciated! Thanks in advance
