which bit do you want, and will it always be the same part of the url?

**turpentyne** · Sep 7, 2011, 07:40 PM

all I want is the last part: "someone". I know what I wrote would pull more than that, but I'm just testing to get it to work.

The rest i don't need, but the folder names might change. Probably the same number of folders every time though.

<body>
<div id = "d"> </div>
</body>
<script>

function doit() {

myURL = "http://www.test.com/folder1/folder2/someone"

var parts = myURL.split('/');
var result = parts[parts.length-1];

alert(result);

}
doit()
</script>

always gives whatever is after last /

**xelawho** · Sep 7, 2011, 07:58 PM

this gets the last bit of the url, split by /

Code:

function splitUrl() {
	str="http://www.test.com/folder1/folder2/someone"
	bits=str.split("/");
	for (var a = 0; a < bits.length; a++) {
	result=bits[bits.length-1];	
		}
		alert(result);	
	}

I must be missing something...

that script alone works fine, but I wasn't giving you the whole picture because I didn't think it was necessary. Maybe it is, because when I incorporate it, I don't get any result. Here's the script in complete form, with your version of the split. I have an alert in there just before it that shows theURL is correct, but then the rest can't seem to take it and split it:

Code:

<script>

function doit() {


var theURL = null;

       var spans = document.getElementsByTagName("span");
       for ( var s = 0; s < spans.length; ++s )
       {
           // searching through spans for the class name:
           var span = spans[s];
           if ( span.className.indexOf("posted-by") >= 0 )
           {
               // here's the right one
               // getting href from inside that span:
               var useit = span.getElementsByTagName("a")[0];
               // and now the image link:
               theURL = useit;
               break; // just the one
           }
        }
        if ( theURL == null ) 
        {
            alert("failed!");
        } else {

               alert(theURL); // just an alert to see if it's working to here

               var parts = theURL.split('/');
var result = parts[parts.length-1];

alert(result); // this is the alert that isn't appearing for me.

}
}
</script>  testing<br /> <input onclick="javascript:doit();return false;" type="button" value="--" /> <br />

Code:

var theURL = null;

       var spans = document.getElementsByTagName("span");
       for ( var s = 0; s < spans.length; s++ )
       {
           // searching through spans for the class name:
           var span = spans[s];
           if ( span.className.indexOf("posted-by") >= 0 )
           {               
               var useit = span.getElementsByTagName("a")[0];              
               theURL = useit.href;
               break; // just the one
           }
        }
        if ( theURL == null ) 
        {
            alert("failed!");
        } else {



               alert(theURL); // just an alert to see if it's working to here

               var parts = theURL.split('/');
var result = parts[parts.length-1];

alert(result);

}
}
</script>  
testing<br /> <input onclick="javascript:doit();return false;" type="button" value="--" /> <br /><span class="posted-by"><a href="http://www.test.com/folder1/folder2/someone"></a></span>

Because eveything in javascript(well almost everything) is an object
and objects in native code usually have a tostring method
that is envoked whenever you use the object as a string
but not when refferencing a method , generally.
