1,通过src显示frame
url: webroot/iframe/1/main.jsp
</script>
<body >
<frame>
<div>
<iframe name="query" src="iframe/1/query.jsp?id=12"></iframe>
<iframe name="list"></iframe>
</div>
<div>
<iframe name="theName"></iframe>
</div>
</frame>
</body>
url:webroot/iframe/1/query.jsp
<body>
<form action="iframe/1/list.jsp" method="post" target="list">
<%=request.getParameter("id") %>
<input type="text" name="theName">
<input type="submit" value="Submit"/>
</form>
</body>
url:webroot/iframe/1/list.jsp
<body>
<%=request.getParameter("theName") %>
</body>
2,通过设置frame.window.location显示frame
<script type="text/javascript">
function loadQuery() {
query1.window.location = "query.jsp?id=12";
}
</script>
<body οnlοad="loadQuery();">
<frame>
<div>
<iframe name="query1" ></iframe>
<iframe name="list"></iframe>
</div>
<div>
<iframe name="theName"></iframe>
</div>
</frame>
</body>
3关于相对路径
query1.window.location 相对于当前目录
<iframe name="query" src="iframe/1/query.jsp?id=12"></iframe>
iframe的src 相对于项目根目录
