continue with this topic.
I wrote some scripts to try to loop all objects in the browser (say,
firefox), and made it below :
{{{
<script type="text/javascript">
function Hashtable()
{
this._hash = new Object();
this.add = function(key,value){
if(typeof(key)!= "undefined"){
if(this.contains(key)==false){
this._hash[key] = (typeof(value)=="undefined"?
null:value);
return true;
} else {
return false;
}
} else {
return false;
}
}
this.remove = function(key){delete this._hash[key];}
this.count = function(){var i=0;for(var k in this._hash){i++;}
return i;}
this.items = function(key){return this._hash[key];}
this.contains = function(key){return typeof(this._hash[key])!=
"undefined";}
this.clear = function(){for(var k in this._hash){delete this._hash
[k];}}
this.toString = function(){
var str = [];
for (var i in this._hash){ str.push(i.toString()); }
return str.join("<br />");
}
}
var vars = new Hashtable();
function takesnapshot()
{
list = function(obj)
{
if(obj.toString() == 'vars') return; // exclude vars self.
vars.add(obj.toString(), obj.toString());
for(var p in obj) list(p);
}
list(window);
// now, vars is a snapshot of window.
}
setTimeout(takesnapshot, 10);
setTimeout(function(){
alert("vars len = " + vars.count());
document.body.innerHTML = vars.toString();
}, 2000);
</script>
}}}
However, it didn't output what I wanted. Moreover, the output differed
between IE and firefox (or Chrome etc.)
Is it caused by the single threading implementations of javascript?
Thanks for any idea.
