View Full Version : How to find the field that has the focus once submit button is clicked?

11 Jun 2014, 1:19 PM

I am using ExtJs 4.2. I have a form which has some 15-20 fields which are text and combo boxes. Now when I click the submit button on this form, I need to check which field has the focus at the time of submitting the form. How do I know that?. Is there a way to know which field has focus during form submission?.

Focus event has an EventObject parameter, you could use EventObject's getRelatedTarget (http://docs.sencha.com/extjs/4.2.2/#!/api/Ext.EventObject-method-getRelatedTarget)() to find the field.

Try adding this listener to the Submit button:

listeners: {
focus : function(btn, The, eOpts){
console.log(' Field Ref > ', The.getRelatedTarget());
console.log(' name > ', The.getRelatedTarget().name);
