Hack or clean my hacked Javascript

Hiya all

I have hacked this code together to get the path of the current URL and add it to a new url and made the browser request the new URL.

I was wondering if you code ninjas could do this more simply or clean er :)

<script>
var getLocation = function(href) {
    var l = document.createElement("a");
    l.href = href;
    return l;
};
var l = getLocation(window.location.href);
console.debug(l.pathname)

var img = document.createElement("img");
img.onload = function(e) {
	var container = document.getElementById("imageContainer");
	container.appendChild(e.target);
}
var imgurl = "http://site.comr?r=@page_" + l.pathname
img.setAttribute("src",imgurl);

document.write(l.pathname);

</script>
<div id="imageContainer"></div>

Open in new window

What do you mean?

It will request the URL from the server and load it into the browser. Since you do not seem to need to display the actual image, that is all the code does. Requests the URL from server (or cache if loaded before)

What exactly are you trying to accomplish?

( for starters, get rif of the first function, it's redundant )

<script>
var l = window.location;
console.debug(l.pathname)

var img = document.createElement("img");
img.onload = function(e) {
	var container = document.getElementById("imageContainer");
	container.appendChild(e.target);
}
var imgurl = "http://site.comr?r=@page_" + l.pathname
img.setAttribute("src",imgurl);

document.write(l.pathname);
</script>

Hiya kozaiwaniec

I want to run the code on a page ( site.com/dir/page.html )

Extract the directory for the URL ( /dir/page.html )

Then call an image with a variable ( othersite.com/imagename.png?r=/dir/page.html )

Does that explain it?

really i just have to request the image. I put it in the div so that i could confirm that the image was requested. :)

OK.

Then I think your script is good to go without that first function like I posted above.

that's me 2 cents :)

This would do it

<script>
var l = window.location;
var img = new Image().src= "http://site.comr?r=@page_" + l.pathname;
</script>

If you want debugging:


<script>
var l = window.location;
var img = new Image();
img.onload=function() { console.log(this.src+' was loaded'); }
img.onerror=function() { console.log(this.src+' was not loaded') };
img.src= "http://site.comr?r=@page_" + l.pathname;
</script>

Hello mplungjan

Thank you for the code. Will this code actually request the constructed url from the browser?
