"undefined" with setTimeout

304 100+
hi,
I am posting below my javascript code,
function displaynames(name)
{
var names = name.split(",");
var t = setTimeout("shownames('" + names + "')",5000);
}

function shownames(names)
{
var i=0;
while(i<names.length)
{
alert(names[i]);
i=i+1;
}

Initially displaynames gets called, then after the split, it calls the shownames function. But when i try to display the values through the while loop i get "undefined" instead of the real values.

Am able to display the values in the displaynames function.

any idea as to whats going wrong here?

SetTimeout evaluates its first argument to a string,
so the array is joined before it is passed to shownames.

Pass the string to displaynames and do the split in shownames:

Expand|Select|Wrap|Line Numbers
  1. function displaynames(name){
  2.     var t = setTimeout("shownames('" + name + "')",5000);
  3. }
  4.  
  5. function shownames(name){
  6.     var names = name.split(",");
  7.     var i=0, L=names.length;
  8.     while(i<L){
  9.         alert(names[i++]);        
  10.     }
  11. }
