demo like this: http://jsfiddle/qcNFF/ ?

Good read: http://api.jquery./prop/

code

$(function() {
    alert(' Before change => ' + $('#someinput').prop('placeholder'));
    $('#someinput').prop('placeholder', "text changed- hulk");
    alert(' After change => ' + $('#someinput').prop('placeholder'));
});​

here's a quick demo for you:

the fiddle code http://jsfiddle/nickadeemus2002/H7MG7/

just use jquery's .attr() method to changed the string.
