jQuery Quiz

Change the text of a div element using an AJAX POST request:

$("input").keyup(function(){
txt=$("input").val();
$.post("demo_ajax_gethint.asp",{suggest:txt},function(result){
$("span").html(result);
});
});

The post() method is used to perform an AJAX HTTP POST request.

$(selector).post(url,data,success(response,status,xhr),dataType)
