如何获得request.setAttribute()中的值

Question

主页面中嵌套了iframe，想把请求的结果传入到iframe中。但我不想用session，有什么办法能够把request.setAttribute("info",info);的值传递给iframe么。感觉iframe是第二个页面一样，request只能将值传递给主页面

Answer 1

试试下面代码：

[code="HTML"]

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;

[/code]

然后到iframe页面，从iframe中取值
[code="JavaScript"]
var list = window.top.frames["promotionlist"].promotionList;
[/code]
