Answer 1

Your question is all over the place - the question / HTML / JavaScript dont match up .... below is a way to update the href and text of an anchor (not a div) on the click of a button

#msdhoni

JavaScript :

$('#Button1').click(function() {
    $('#Link1').attr('href',"http://search.twitter.com/search?q=#" + $('#Text1').val());
    $('#Link1').text("#" + $('#Text1').val());
});

Note: You need to add an ID to the anchor to make this code work
