javascript - Facebook Dom Placeholder on Password -

-

facebook has "dom placeholder" on password field when logging on. when click on input password, placeholder disappears , allows me type password "masked".

is javascript related , how go on replicating script?

yes, can done via javascript, browsers support natively. placeholder attribute html5 addition; browsers (such webkit-based browsers) support already.

example using jquery 1.4

<!-- work automatically browsers --> <input type="text" placeholder="enter text">   <!-- script browsers don't support natively --> <script type="text/javascript"> $.fn.placeholder = function(){    // quit if there's support html5 placeholder   if (this[0] && 'placeholder' in document.createelement('input')) return;     return     .live('focusin',function(){        if ($(this).val() === $(this).attr('placeholder')) {         $(this).val('');       }      }).live('focusout',function(){        if ($(this).val() === ''){         $(this).val( $(this).attr('placeholder') );       }_       }); }  $('input[placeholder]').placeholder(); </script>

note: code copied this pastie linked jquery 1.4 hawtness. haven't verified works across browsers. can find other javascript solutions on google if don't use jquery.
