Question

I have a form, with a button called add rows. I would like to disable this button after user clicks on it thrice.

Answer 1

You could set a click counter on the button, but seeing as it is called “add rows”, I suppose you might be able to just count the number of rows, and determine if it should be disabled that way.

bool disabled = true;
$('#add-rows').prop('disabled', disabled);

Replace true with your favourite means of calculating the number of rows.
