Is there any way to make a javascript array and leave out the commas between each thing in the array so it looks like 123 instead of 1,2,3,

the commas are how the array gets delimited so you really can't get rid of them. you can try setting the items one at a time like this:

var myArray = new Array();

myArray[ 0 ] = "item one";
myArray[ 1 ] = "item two";

Do you mean a comma while you make the array show up on screen or a comme while putting them in. For showing it up on screen a script could easily be written to avoid the commas and probably already has.
