Button and onchange in html form

Question

There is a rather simple html application.

Changing text field will cause a submit, follow by a redraw. Pressing button will cause a submit, too.

When changing a field and leave it by pressing a button, the browser run into a conflict. The browser starts one submit, aborts it and do the next submit. The result is unreliable.

Is there a simple solution to get one submit with button and field without switching to some AJAX approach (say GWT)?

Answer 1

You could cancel any other event handler when starting to submit the form. This is similar to disabling a submit after clicking it, to prevent the form being submitted twice by impatient users.
