Javascript - htc behavior has no effect on newly created elements
I'm trying to identify objects in javascript. My problem is, that msie DOM nodes are not instances of any Object descendant, so I cannot set or get property on such an instance. I'm trying to make a workaround for that with htc behaviors (only nodes with style can have behavior, so this is a half solution, but better than nothing):
identity.htc:
<PUBLIC:COMPONENT>
<script type="text/javascript">
for(property in Object.prototype)
{
element[property]=Object.prototype[property];
}
</script>
</PUBLIC:COMPONENT>
test.html:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<title>javascript identity workaround</title>
<!--[if IE]>
<style type="text/css">
*{behavior:url(identity.htc)}
</style>
<![endif]-->
<script type="text/javascript">
(function ()
{
var i=0;
var table={};
Object.prototype.identity=function ()
{
if (!this.__hashcode__)
{
this.__hashcode__=++i;
table[i]=this;
}
return this.__hashcode__;
};
Object.identify=function (i)
{
return table[i];
};
})();
window.onload=function ()
{
var body=document.getElementsByTagNa开发者_开发问答me("body")[0];
var existingElement=document.getElementById("existingElement");
var newElement=document.createElement("div");
newElement.addBehavior("identity.htc");
alert(body.identity()); //1
alert(existingElement.identity()); //2
alert(newElement.identity()); // expected: 3, real: method not supported
};
</script>
</head>
<body>
<div id="existingElement"></div>
</body>
</html>
My problem is, that I cannot use the identity method on the newly created elements. I tried to add the behavior with the addBehavior method, but it didn't help. Has somebody a solution for this?
I got the solution:
<PUBLIC:COMPONENT lightWeight="true">
