Question

iframe嵌套frameset的页面，结构如图，点击顶部导航中左侧的正方形icon，切换left显示隐藏，JS要怎么写？

一级页面<nav class="nav-fixed-top"></nav><iframe src="二级页面" name="iframepage" id="iframepage" ></iframe><nav class="nav-fixed-top"></nav>二级页面<frameset rows="*" cols="220,*" id="frame"> <frame src="left.html" name="leftFrame" noresize="noresize" marginwidth="0" marginheight="0" frameborder="0" scrolling="auto" /> <frame src="main.html" name="main" marginwidth="0" marginheight="0" frameborder="0" scrolling="yes" /></frameset>

Answer 1

onClick=document.getElementById("iframepage").frame.cols="0,*";

要切换显示和隐藏，不仅仅是隐藏左侧菜单
