title: Why isn't the submit button included in the post when submitting a form with jquery
body: <p>When a form is submitted with a button click or by pressing enter, the submit button is included in the posted fields. However if the form is submitted with jquery(<code>$('#some_form').submit();</code>), the submit button isn't included. If a click event is triggered on the button, it's included in the posted fields.<br>
  Is this behavior normal? Is there a way to include the button in the submitted fields by using the submit method? </p>
  
  <p>**EDIT: ** As @Pointy stated in the comments: </p>
  
  <blockquote>
    <p>An "Enter" from an input field can cause a submit; the rules for that are somewhat complicated. Usually it has to do with how many input fields there are (like, just one, or more than one).</p>

  <p>So apparently not every time when enter is pressed the form is submitted, but I couldn't find any info about it. Could someone post a link, or explain these rules about what triggers the form submission and which form fields are included?</p>
