jQuery html() in Firefox (uses .innerHTML) ignores DOM changes

Firefox doesn't update the value attribute of a DOM object based on user input, just its valueproperty - pretty quick work around exists.

 DOM:

opened_dcf8ba67-46ab-42d4-923e-51f7c5ba3bb3" onclick="cnblogs_code_hide('dcf8ba67-46ab-42d4-923e-51f7c5ba3bb3',event)" style="display:none">

function DisplayTextBoxValue(){
  var element = document.getElementById('textbox');
  // set the attribute on the DOM Element by hand - will update the innerHTML
  element.setAttribute('value', element.value);
  alert(document.getElementById("container").innerHTML);             
  return false;
}

 

 

jQuery plugin that makes .formhtml() automatically do this:

 

(function($) {
  var oldHTML = $.fn.html;

  $.fn.formhtml = function() {
    if (arguments.length) return oldHTML.apply(this,arguments);
    $("input,textarea,button", this).each(function() {
      this.setAttribute('value',this.value);
    });
    $(":radio,:checkbox", this).each(function() {
      // im not really even sure you need to do this for "checked"
      // but what the heck, better safe than sorry
      if (this.checked) this.setAttribute('checked', 'checked');
      else this.removeAttribute('checked');
    });
    $("option", this).each(function() {
      // also not sure, but, better safe...
      if (this.selected) this.setAttribute('selected', 'selected');
      else this.removeAttribute('selected');
    });
    return oldHTML.apply(this);
  };

  //optional to override real .html() if you want
  // $.fn.html = $.fn.formhtml;
})(jQuery);
