help in getting variable by URL

[Tezler]

how do i get the variable at the end of a URL so i can use it?

script.html?srcPic=001.jpg

HOW i get the 001.jpg?

so can use it as the src image?

I pass the variable to the end ok i think

THANKS,

Here's a relatively lame solution that only works if there's only one variable in the URL query string.

<SCRIPT LANGUAGE="JavaScript">
<!--
	var urlstring = location.href;
	alert(urlstring);
	var qrystring = urlstring.substring(urlstring.indexOf("=") + 1, urlstring.length);
	alert(qrystring);
	document.write("<IMG SRC='" + qrystring + "'>");

// -->
</SCRIPT>

Playing with indexOf() and substring would enable you to handle more than one variable.
Hope this helps,

or eval(this.location.href.split("?")[1])

here's a version that would work if there's multiple variables in the query string...

function getQuery(name){
	var query = self.location.search;
	if(query.length > 0){
		name = name+"=";
		var str = query.substring(1);
		var start = str.indexOf(name);
		if(start == -1) return null;
		start += name.length;
		var end = str.indexOf("&", start);
		if(end == -1) end = str.length;
		return unescape(str.substring(start,end));
	}else{
		return null;
	}
}

function getImageTag(src){
	return '<img src="'+src+'" />';
}

document.write(getImageTag(getQuery("srcPic")));
