本人用dephi想开发一个小工具读取实时的股票价格,该数据是由sina提供的如下:http://hq.sinajs.cn/list=sh601006在页面中显示没有问题
<head>
<title></title>
</head>
<body></body>
<script type="text/javascript" src="http://hq.sinajs.cn/list=sz000735" charset="gb2312"></script>
<script type="text/javascript">
var elements = hq_str_sz000735.split(",");
document.write("current price:" + elements[3]);
</script>
</html>请问如果用dephi如何得到该数据,不要求使用IE方式.
http://hq.sinajs.cn/list=sh601006返回的是一个字符串,如何获得这个字符串,如果非要使用IE,IE也最好隐藏,拜求了。
