Question

如何获得request.setAttribute中的值

Answer 1

试试下面代码：

Html代码
<script type="JavaScript">
var list = [
<%
List list = (List) (request.getAttribute("promotionlist"));
for (Iterator it = list.iterator; it.hasNext();) {
out.print("\"" + it.next() + "\"");
if (it.hasNext()) out.println(", ");
}
%>
];
document.getElementById("iframeContent").promotionList = list;
</script>

然后到iframe页面，从iframe中取值

Javascript代码
var list = window.top.frames["promotionlist"].promotionList;
