iframe根据子页面自动调整大小
function IFrameReSize(iframename) {
var pTar = document.getElementById(iframename);
if (pTar) { //ff
if (pTar.contentDocument && pTar.contentDocument.body.offsetHeight) {
pTar.height = pTar.contentDocument.body.offsetHeight;
} //ie
else if (pTar.Document && pTar.Document.body.scrollHeight) {
pTar.height = pTar.Document.body.scrollHeight;
}
}
}
//iframe宽度自适应
function IFrameReSizeWidth(iframename) {
var pTar = document.getElementById(iframename);
if (pTar) { //ff
if (pTar.contentDocument && pTar.contentDocument.body.offsetWidth) {
pTar.width = pTar.contentDocument.body.offsetWidth;
} //ie
else if (pTar.Document && pTar.Document.body.scrollWidth) {
pTar.width = pTar.Document.body.scrollWidth;
}
}
}
使用方法如下：
<iframe src="Main.aspx" scrolling="no" frameborder="0" height="100%" id="mainFrame" width="100%" onload='IFrameReSize("mainFrame");IFrameReSizeWidth("mainFrame");'></iframe>
