<SCRIPT language=JavaScript src="http://finance.sina.com.cn/realstock/js/new/sh/600296.js" id="script1">
</SCRIPT language=JavaScript >
<script>
var url="600296.js";
document.all.script1.src="http://finance.sina.com.cn/realstock/js/new/sh/"+url;
alert(document.all.script1.src);
</script>
<body>
</body>
