Hi

i have a element in a array form_links called "motor"

in brief,

I have the below code.

linkN = "motor"

form_links.splice(linkN,1,"removed");

This doeswork though... it's adding a new element at a new location in array

Why is this. I simply wish to either completely remove the element or replace with "removed"

cheers

Well. it seems logical to mee that this adds a new element, given the reference I've got:

Changes the content of an array, adding new elements while removing old elements

If you want to remove an element, you cannot that easily.
You need to parse your array, and recopy a new one, excluding the parts you don't want.

But, you can more easily replace the value of your array with removed.
Use this (javascript function.I do hope the formatting stay....):

PHP Code:

/**
 *Return the specified array with every occurence who have _lookup as value replaced by _replace
 * @param     Array          _array               The array to parse
 * @param     String         _lookup             The string to look up for
 * @param     String         _replace            The string to replace _lookup with
 * @return      Array        
 */
function replaceVal(_array,_lookup,_replace){
  for(var i=0;i<_array.length;i++){
        if(_array[i]==_lookup){
            _array[i]=_replace;
        }
  }
    return _array;
} 


Then calling replaceVal( form_links,linkN,'removed');
will replace every occurences of linkN in the array with the text removed.
