Should jQuery s form submit not trigger onSubmit within the form tag

Question

I have the following    lt script type  text javascript  gt  function CancelFormButton button          button form  submit       lt  script gt    lt form onsubmit  alert  here     gt   lt input type  button  value  Cancel  onClick  CancelFormButton this      gt   lt  form gt    When I click the  Cancel  button  the onsubmit from the form tag is not triggered   This line instead submits the form successfully    button form  submit    but skips the alert  here    within the onsubmit in the form tag   Is this correct or am I doing something wrong   By the way  in this case  I want this functionality  but I m just wondering if I m going to run into a problem in a browser where the onsubmit is triggered

This work around will fix the issue found by  Cletus   function submitForm form          get the form element s document to create the input control with        this way will work across windows in IE8      var button   form ownerDocument createElement  input          make sure it can t be seen disrupts layout  even momentarily      button style display    none         make it such that it will invoke submit if clicked     button type    submit         append it and click it     form appendChild button  click          if it was prevented  make sure we don t get a build up of buttons     form removeChild button       Will work on all modern browsers Will work across tabs spawned child windows  yes  even in IE lt 9  And is in vanilla   Just pass it a DOM reference to a form element and it ll make sure all the attached listeners  the onsubmit  and  if its not prevented by then  finally  submit the form

I suppose it s reasonable to want this behavior in some cases  but I would argue that code not triggering a form submission should  always  be the default behavior  Suppose you want to catch a form s submission with      form   submit function e       e preventDefault          and then do some validation on the input  If code could trigger submit handlers  you could never include     form   submit     inside this handler because it would result in an infinite loop  the SAME handler would be called  prevent the submission  validate  and resubmit   You need to be able to manually submit a form inside a submit handler without triggering the same handler   I realize this doesn t ANSWER the question directly  but there are lots of other answers on this page about how this functionality can be hacked  and I felt that this needed to be pointed out  and it s too long for a comment

Sorry  misunderstood your question  According to Javascript - capturing onsubmit when calling form submit     I was recently asked   quot Why doesn t the form onsubmit event get fired when I submit my form using javascript  quot  The answer  Current browsers do not adhere to this part of the html specification   The event only fires when it is activated by a user - and does not fire when activated by code    emphasis added   Note   quot activated by a user quot  also includes hitting submit buttons  probably including default submit behaviour from the enter key but I haven t tried this    Nor  I believe  does it get triggered if you  with code  click a submit button
