jQuery(\'#yourForm\').bind(\'submit\',function(e){

    //do your test
    //if fails 
    e.preventDefault();

});

$(document).ready(function(){
    $(\'#yourDiv\').click(function() {
        $(\'#yourForm\').submit();
    });
});

$(\'#form_element\').submit(function() {
    return false;  // do this if you don\'t want to submit the form
});

<div id=\"divElement\">
<input type=\"hidden\" name=\"buttonIsClicked\" value=\"0\" />
</div>

$(\"#divElement\").click( function() {
  $(this).children(\"input[name=buttonIsClicked]\").val(1);
});

$(this).parent().find(\"input[type=buttonIsClicked]\");

$(myFormElement).submit(function() {
  if($(this).find(\"input[name=buttonIsClicked]\").val() == 0)
    return false;
  //proceed here if the button div is clicked
}
