       type: 'POST',
       data: somedata,
       success: function (msg) {
          if (!msg) {
             // I wanna to stop '#form1' submit here,how to do that? I can only modify the code in the ajax call.
          }
       }
    });
 });

  // Your AJAX call here
  // blah blah blah

  return false;  // Stop form submit
}
