在开发项目过程中，用iframe嵌套，会发现一个问题，用iframe嵌套的html结构右边不会自动适应高度。
这时候找到了一个解决方法：
2、记住要引入iframe.js文件
下面是iframe.js的具体内容
-1 ? true : false;
var isFireFox = browserVersion.indexOf("FIREFOX") > -1 ? true : false;
var isChrome = browserVersion.indexOf("CHROME") > -1 ? true : false;
var isSafari = browserVersion.indexOf("SAFARI") > -1 ? true : false;
var isIE = (!!window.ActiveXObject || "ActiveXObject" in window);
var isIE9More = (! -[1,] == false);
function reinitIframe(iframeId,minHeight) {
try {
var iframe = document.getElementById(iframeId);
var bHeight = 0;
if (isChrome == false && isSafari == false)
bHeight = iframe.contentWindow.document.body.scrollHeight;
var dHeight = 0;
if (isFireFox == true)
dHeight = iframe.contentWindow.document.documentElement.offsetHeight + 2;
else if (isIE == false && isOpera == false)
dHeight = iframe.contentWindow.document.documentElement.scrollHeight;
else if (isIE == true && isIE9More) {//ie9+
var heightDeviation = bHeight - eval("window.IE9MoreRealHeight" + iframeId);
if (heightDeviation == 0) {
bHeight += 3;
} else if (heightDeviation != 3) {
eval("window.IE9MoreRealHeight" + iframeId + "=" + bHeight);
bHeight += 3;
}
}
else//ie[6-8]、OPERA
bHeight += 3;
var height = Math.max(bHeight,dHeight);
if (height < minHeight) height = minHeight;
iframe.style.height = height + "px";
} catch (ex) { }
}
function startInit(iframeId,minHeight) {
eval("window.IE9MoreRealHeight" + iframeId + "=0");
window.setInterval("reinitIframe('" + iframeId + "'," + minHeight + ")",100);
}
