How to keep focus if input is invalid in dijit.form.NumberTextBox?

Question

I have a NumberTextBox in a grid cell. How do I keep focus if input is out of range or invalid? (such that user cannot click away from the cell)?

Thanks!

You can try something like this

function lockUserOnInput() {

  if( ! dijit.byId('NumberBox').validate()) {
     dijit.byId('NumberBox').focus();
     dijit.byId('NumberBox').inputNode.focus(); // make damn sure
  }

}

setInterval(lockUserOnInput, 250); // set the interval as intense as you need it to be :)
