HOW DO I REMOVE AN ELEMENT FROM AN ARRAY AND THEN RE INDEX THAT ARRAY SO I DONT GET "undefined" IN MY OUTPUT OF THE ARRAY.

IE

3 ARRAY elements defined

item_links[0] = "one"
item_links[1] = "two"
item_links[2] = "three"

outputing the above correctly shows

one
two
three


HOWEVER if I

item_links.splice(0,1); /* remove element 0 */

the output is then

undefined
two
three



cheers

Use 2 arrays to provide a simple swap between the arrays.

var item_links=new Array();
var temp_array=new Array();

item_links[0] = "one"
item_links[1] = "two"
item_links[2] = "three"

for(i=0;i<item_links.length;i++){
  document.write(i + " " + item_links[i] + "<br />");
}

document.write("<hr />");

temp_array=item_links.splice((0,1));
item_links=temp_array;

for(i=0;i<item_links.length;i++){
  document.write(i + " " + item_links[i] + "<br />");
}

Output:
0 one
1 two
2 three
----------------------------------------------------------------------------------------
0 two
1 three

Thanks Ibo.
Much appreciated.
Trying out now

Well i found some serious problems with it. I thought my browser has gone daft.

It now works in mine without the need to use a temp array(although its good practice to do so). Initially i replicated your code and I too got undefined. Now its rolling back fine and I'm baffled by this behaviour.

Anyway the 2 arrays is a sound programming technique and It works for all sorts of programming tasks.

Even if thsi one is a little wierd.

Try this method

<script type="text/javascript">
for( index in item_links ) {
    document.write( index + " " + item_links[index] + "<br />" );
}
</script>

to iterate through your arrays.
