Jquery中post 请求后无数据返回的问题、jquery遍历json

<script src="Scripts/jquery-1.4.1.js" type="text/javascript"></script>
<wbr><wbr><wbr> &lt;script type="text/javascript"&gt;<br><wbr><wbr><wbr><wbr><wbr><wbr><wbr> $(document).ready(function () { //ready-start<br><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr> $.post(//post-start<br><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr> "/test1.ashx", { <span style="color:#ff3c12">data1: new Date()</span> }, function (text) {<br><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr> $("#ttt").text(text);<br><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr> }<br><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr> ); //post-End<br><wbr><wbr><wbr><wbr><wbr><wbr><wbr> });<wbr><wbr> //ready-End<br><wbr><wbr><wbr> &lt;/script&gt;</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>

我一直搞了好久，反复的看了，没错，怎么会没返回 ？没头绪，想起了缓存，就使用不同的请求参数测试 ，果然是这个问题！<wbr></wbr>

<wbr>需要要请求数据之后，<span style="color:#fc3a11">另加一个动态的数据（如 new Date() 当前时间），</span>告诉服务器这是<span style="color:#fc3a11">新的请求</span>，服务器才会每次都返回数据！</wbr>
