Display Data After Submit, but ....

If I put this code, if(ds="rut|")return; with =
the submit button don't work, so alert(ds); don't give me any result.

If I use this code, if(ds=="rut|")return; with "=="
the submit button work, and alert(ds); show me a pop with this rut%7C%7C (when search box is empty), if I put an id the alert code show me a pop up windows with the di, like this rut%7C98765432-1%7C. (id 98765432-2)

You're a genius!. Now works as I wish.

Another question this applies to this format in particular. Now I've only one grid.

What happens if I set another grid and I need another column to filtrate?.
I would have to put another line in the grid.js?


thanks.
