Bootstrap validator - Place error message on placeholder

Question

How to place the Bootstrap validator error message inside the input placeholder?

I tried errorPlacement but it seems to get no effect.

jsFiddle

 $('.js-form').validator({
            disable: false,
            errorPlacement: function(error, element) {
                if(element.length) {
                    element.attr("placeholder", error.text());
                }
            }
        });

Answer 1

A possible solution is to save the placeholders and handle the submit button:

$(function () {
  // save placeolders....
  $('.js-form').find(':input').each(function(index, ele) {
    $(ele).attr('placeholderSaved', $(ele).attr('placeholder'));
  });
  
  $('.js-form').validator({disable: true}).on('submit', function (e) {
    $('.js-form').find('div.with-errors').each(function(index, element) {
      var cacheEle = $(element);
      var errMsg = cacheEle.find('li').text().trim();
      
      // on error change placeholder with error message
      if (errMsg.length > 0) {  
        cacheEle.hide().prev().attr('placeholder', errMsg);
      } else {
        // on success restore placeholder
        cacheEle.hide().prev().attr('placeholder', cacheEle.hide().prev().attr('placeholderSaved'));
      }
    });
  });
});
