remove characters in string after specific occurrence

Hoping you guys can help me out.

I have a dynamic url and I need some javascript to basically trim the string after the specific occurrence of a character.

EXAMPLE:

I have this url

Assessment/testdir2/TestDIR3/lecture slides 1as.pdf

and I need to remove everything after the 2nd slash and including the 2nd slash.

How would I do this?

A very basic JS solution:

function removeAfterSlash(word, numberOfElements) {
    var splitWord = word.split('/');
    var newWord = '';
    for(var i = 0; i < numberOfElements; i++) {
        if(i != (numberOfElements - 1)) {
            newWord += splitWord[i] + '/';
        } else {
            newWord += splitWord[i];
        }   
    }
    document.write(newWord);
}
removeAfterSlash('Assessment/testdir2/TestDIR3/lecture slides 1as.pdf', 1);

Simply split's the word into an array by looking for a / and then you can join the elements you need back together. The function takes the word and how many 'segments' you want to join back together.

See it on jsfiddle.

Try this:

var url= "Assessment/testdir2/TestDIR3/lecture slides 1as.pdf"
var locs = myString.split('/');
var newUrl = "";
for (var i = 2; i < locs.length; i ++) {
    newUrl += "/" + locs[i];
}

This method will then ignore the first two folders and will work regardless of how many other folders you have in the url.
