Placeholder Polyfill

function hasPlaceHolder() {
  return 'placeholder' in document.createElement('input');
}

function html5forms() {
  var formPlaceholder = hasPlaceHolder();
  if (formPlaceholder === false) {
    $('input[type=text]').each(function() {
      if($(this).attr('placeholder')) {
        var placeholderText = $(this).attr('placeholder');
          $(this).attr('value',placeholderText);
        }
      });
    emptyTextBox();
  }
}
document.addEventListener('DOMContentReady', html5forms, false);
