How to give focus() after an alert()?

Question

I have something like:

Answer 1

Your code seems to work as expected for me. See this fiddle. Are you seeing some other behavior? I see that I type a number in textbox1. Then when I tab over to textbox2 I get Invalid Part! error and focus stays on current textbox.

Updated - Since this only seems to play nice in Chrome you could keep track of whether an error exists. If so then handle it.

var error = null;
function checkForErrors() { 
   if (error) { error.focus(); error = null; }            
}

function validatePart(node) {
   if (badpart) { error = node; }
}

function saveOldQuantity(node) {
   checkForErrors();
}
