jquery prohibits carriage return from triggering form submission_jquery

Copy code The code is as follows:

                                                                                                                                                                                 Query
                                           

The carriage return event of the test text box will trigger the submission of the above form. This is the default behavior of the browser. To disable automatic submission, cancel the default event in the text box.

Copy code The code is as follows:

$('.a').keypress(function(e){
                 if(e.keyCode==13){
                   e.preventDefault();
            }

Tested IE10 FF29 and it works fine
