problem removing item from an array

[lisaad]

I'm having trouble removing an element from an array. my array is filename, and i want to randomly select one item, then remove it so it isn't selected again.

here's my code:

selectRandom = function(){
    filename =  ["p1_1.swf", "p1_2.swf", "p1_3.swf", "p1_4.swf", "p1_5.swf", "p1_6.swf"];
    path =  "http://a.parsons.edu/~lisa/spring05/interactivity/final/swfs/";
    i =  filename.length;   
    k =  Math.floor(Math.random()*i);   
    randomFile = filename[k];
    filename.splice(k,1);   
    return(randomFile);    
    return(path);      
}

is there something I'm missing?

The problem is that everytime you call selectRandom() you're assigning filename all of your clips again. You need to move the lines filename = and path = somewhere outside of your function. This might be more of what you're looking for:

filename =  ["p1_1.swf", "p1_2.swf", "p1_3.swf", "p1_4.swf", "p1_5.swf", "p1_6.swf"];
    path =  "http://a.parsons.edu/~lisa/spring05/interactivity/final/swfs/";
    
    selectRandom = function(){
            k = random(filename.length-1);
            randomFile = filename[k];
            filename.splice(k,1);
            return(randomFile);
    }

Then you could use it somewhere like:

filePath = path + selectRandom();

Hope it helps some,
