Placeholder attribute shown below works fine in firefox but if val() is called when the field is empty it returns the placeholder value instead of the actual value in the text.

<input id=tlt type=text placeholder=Enter Title />

JSCode

function placeHolderFallBack() {

   if (placeholder in document.createElement(input)) {

       return;

   }

   else {

       $('[placeholder]').focus(function () {

           var input = $(this);

           if (input.val() == input.attr('placeholder')) {

               input.val('');

               input.removeClass('placeholder');

           }

       }).blur(function () {

           var input = $(this);

           if (input.val() == '' || input.val() == input.attr('placeholder')) {

               input.addClass('placeholder');

               input.val(input.attr('placeholder'));

           }

       }).blur();

       $('[placeholder]').parents('form').submit(function () {

           $(this).find('[placeholder]').each(function () {

               var input = $(this);

               if (input.val() == input.attr('placeholder')) {

                   input.val('');

               }

           })

       });

   }
