Iframe automatically adjusts the size according to the subpage

Reprinted: http://wenwen.soso.com/z/q229512802.htm

// Iframe highly adaptive

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 adaptive width

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;

}

}

}

The usage is as follows:

<Iframe src = "Main. aspx "scrolling =" no "frameborder =" 0 "height =" 100% "id =" mainFrame "width =" 100% "onload = 'iframeresize (" mainFrame "); IFrameReSizeWidth ("mainFrame"); '> </iframe>
