解决ifream自适应问题

用js实现ifream自适应

获取ifream的window对象-contentWindow

    function autoHeight(iframe) {        if (iframe) {            var iframeWin = iframe.contentWindow;            if (iframeWin.document.body) {                iframe.height = iframeWin.document.documentElement.scrollHeight;                iframe.width = document.documentElement.clientWidth;            }        }    }    function changeFrame() {        var f = document.getElementById("myiframe");        autoHeight(f);    }    window.onresize = function () {        changeFrame();    }

        <iframe  id="myiframe" scrolling="no"  style="border: 0px;" width = "100%" onload = "changeFrame()" src = "path"/>        </iframe>
