How to find object with property having specified value?
This code doesn't work

function findPropertyByValue(needle, fObj)
{
	var i;
	for(i in fObj){
		if(fObj==needle) return i;
	}

	var success;
	if(fObj.firstChild!=null){
		success=findPropertyByValue(needle, fObj.firstChild);
		if(success!=null) return "->"+success;
	}
	while(fObj.nextSibling!=null){
		success=findPropertyByValue(needle, fObj=fObj.nextSibling);
		if(success!=null) return "->"+success;
	}
	return null;
}


function CTRL21_7::OnClick(eventObj)
{
	var dest=findPropertyByValue("something", XDocument.DOM);
	if(dest!=null) 	XDocument.UI.Alert(dest);
}

There is error on row "for(i in fObj){" (object doesn't support command)
What's wrong? How to do it?

Hi TTS welcome to the Forums,

We don't have syntax like "for(i in fObj)". We need to use "foreach(i in fObj)" otherwise you can use directly for loop.
If you want to get more information on loops go through this link,

Thanks, but it's js, not c# script
Did I posted this in wrong forum?

Hi TTS,

I am sorry. In C#, we will used to 'foreach' loop but in JScript your syntax is correct. Can you check once 'fObj' object is get the value or not. And one more is what about 'needle' value?

You can get the more information on 'for' and 'for in' loops

Hi,
XDocument.DOM in var dest=findPropertyByValue("something", XDocument.DOM); is just one node, its not an enumerator to loop through it.
Probably you want to loop through the children of "XDocument.DOM".

Of course I want loop through the chidren, but that's not the explanation.
I found that for...in works fine with objects made by script itself such as
obj={"a" : "Athens" , "b" : "Belgrade", "c" : "Cairo"}
but not with
XDocument, XDocument.DOM.firstChild, eventObj and so on.
It's a pity.
