URL catcher

Hello,

I'm new to JavaScripting and have a question that should be simple (I think).

I want a frame that stays constant and checks the URL of a second frame constantly. When ever the URL of frame2 changes frame one catches the new URL and saves it to a VAR.

I think that is should be possible and I think that Javascript would be a good way of doing this. Please let me know if this is possible or if Javascript would not be the best route.

Thanks

 

I don't think Javascript allows a frame to access the content of another frame, unless both are from the same domain.

This should work if they are from the same domain.

// Set this to false, if you want only unique URLs to be added to the var
var uniqueURL = true;

var arURL = new Array();
var lastURL = '', curURL = '';
function storeURL(){
	//In case this doesn't work, replace frames[1] with frames["second_frame_name"]
	curURL = window.parent.frames[1].location.href;
	if(curURL != lastURL){
		var isUnique = true;
		if(uniqueURL){
			for(var i in arURL){
				if(arURL[i] == curURL){
					isUnique = false;
					break;
				}
			}
		}
		if(isUnique){
			lastURL = curURL;
			arURL[arURL.length] = lastURL;
			alert(arURL);
		}
	}
	setTimeout('storeURL()', 1000);
}

PHP:

Call this function on the onload event of your first frame.
