前提：我们可以改动两个域下面的页面代码。...域A域B...比如我们想实现，域A上通过iframe显示域B的页面内容，同时让域A的页面自适应域B的页面高度。...1、在域A的页面，iframe域B的页面<iframe height='200px' id='iframeA' src="http://域B/B.html"></iframe>  ...2、域B的页面B.html写一个窗口加载事件： window.onload = function(){}...  -1、创建一个iframe，设置其高宽为0px（这是为了不占空间）；  -2、获取本页面的完整高度，  -3、设置iframe.src为：域A/set_DomainA_Height.html#接“完整高度”  -4、然后把iframe给append到本页面----document.body.appendChild(iframe)...3、在域A下创建set_DomainA_Height.html...因为本页面跟域A处于同一域，所以就不存在跨域了，可以直接设置域A的Iframe的高度，以此实现高度自适应。...  -1、获取域A的iframe parent.parent.document.getElementById("iframe1"); ...  -2、获取锚点参数--高度值window.location.hash.split("#"); ...  -3、设置域A的高度为得到的值...Done
