新浪的财金频道一直感觉做得很好。但由于最近网速慢的缘故，查看股票信息时网页老是打不开。这几天一直在研究ajax，于是用jquery自己做了一个自动读取新浪股票实时数据的页面。

习惯用prototype的，把脚本部分的代码替换一下即可。
复制代码 代码如下:

<script type="text/javascript" src="prototype.js"></script> 
<script type="text/javascript">... 
function ajaxRequest()...{ 
var myAjax = new Ajax.Request(

...{ 
method: &#39;get&#39;, 
onComplete: setData 
} 
); 
} 
function setData(response) ...{ 
var contents = response.responseText; 
var stocks = contents.split(&#39;;&#39;); 
for(var i=0; i<stocks.length-1; i++)...{ 
var content = stocks[i]; 
var temp1 = content.split(&#39;=&#39;)[0]; 
var temp2 = content.split(&#39;=&#39;)[1]; 
var code = temp1.substr(temp1.length - 6, 6); 
var temp3 = temp2.replace(&#39;"&#39;, &#39;&#39;); 
var name = temp3.split(&#39;,&#39;)[0]; 
var tday_f = temp3.split(&#39;,&#39;)[1]; 
var yest_f = temp3.split(&#39;,&#39;)[2]; 
var curr_f = temp3.split(&#39;,&#39;)[3]; 
var temp_f = curr_f - yest_f; 
$(&#39;a&#39;+i).innerHTML = code;

} else ...{

} 
} 
function pageInit() ...{ 
window.setInterval("ajaxRequest()",3000); 
} 
</script>
