使用jQuery AJAX加载php内容

jQuery之类的东西！：

<form action="toload.php" method="post">Input: <input type="text" id="something" name="something" value="" /><br /><input type="submit" value="Submit!" onclick="submitme()" /><div id="something2"></div></form>

以及提交功能：

function submitme(){var tosend=document.getElementById("something").value;$.ajax({        type: 'POST',        url: 'toload.php',        data: 'something='+tosend,        success: function(msg){ if(msg){     document.getElementById("something2").innerHTML=msg; } else{     return; }        }    });}
