最下面的一个id为"frameMap"的iframe无法自适应宽度，如果在外部div指定宽度为100%后，下面这个iframe就看不到了。
当把左边的div隐藏后这个iframe只是位置向左浮动了，宽度并没有自适应。请教

回复讨论(解决方案)

想iframe宽度自适应，最好用JS

js要怎么做？iframe不固定宽度看不到，固定宽度后不能拉伸，而且当浏览器变下后也看不到了

使用jquery方法，假设你的框架iframe的id为theFrame

function setSize(){
$('#theFrame').css("width",$(window).width());
}

//页面加载时设框架款宽度
$(document).ready(function (){
setSize();
});

//人工拖扯窗口大小时，重设框架款宽度
$(window).resize(function () {
setSize();
});
