Array Problems

[Lizo]

Hi,

How would I go about removing an element from an array. The element to be removed can be at any index, so I cant use pop().

Any ideas??

Thanks, Lizo.

I don't think you want to use pop,because it will remove the last element from the array.
You want to use
array.splice(indexOfElmentToBeRemoved,1);
the above example will remove the element at the provided array index and will return the removed element.

I don't know about why, but I've had some problems using splice(). I forget the details, but in one of the scripts I used I used this instead:
function RemoveElementFromArray(element, array){
result = new Array();
for (i=0;i<array.length;i++){
if (i != element) result[result.length++] = array[i];
}
return result;
}Do you know if any major browsers do not support splice()? Or am I simply wasting my time (as usual)?

Thanks Khalid, Ive got it working now, you did it again hehe.

Adam, my code looks like this


function deleteColor(i)
{
colors.splice(i,1);
colorNames.splice(i,1);
colorHEXValues.splice(i,1);
colorRGBValues.splice(i,1);
}


and the values I pass to it are taken from the selections made in a select box. Im not sure if this helps you, just thought Id show you how I did it.
