1、页面引用ifram
<iframe src="URL" id="iframe" name="iframe" frameborder="0" marginwidth="0" align="left" height="550px" width="100%" scrolling="auto" marginheight="0"
onload="setIframeHeight()">
</iframe>
2、高度自适应,避免出现滚动条
/** iframe高度自适应 **/ function setIframeHeight() { var iframe = document.getElementById("iframe"); if (iframe) { var iframeWin = iframe.contentWindow || iframe.contentDocument.parentWindow; if (iframeWin.document.body) { iframe.height = iframeWin.document.documentElement.scrollHeight || iframeWin.document.body.scrollHeight; } } } /** 改变页面大小是触发 **/ window.onresize=function(){ setIframeHeight(); }
3、父页面获取iframe对象
var iframe = window.frames["iframe"];
var xxx = iframe.document.getElementById("xxx").value;
4、ifame获取父页面对象
var parWin = parent.window;
