js:

function iFrameHeight() { 
var ifm= document.getElementById("iframepage"); 
var subWeb = document.frames ? document.frames["iframepage"].document : ifm.contentDocument;
if(ifm != null && subWeb != null) { 
ifm.height = subWeb.body.scrollHeight; 

}

iframe:

 

下面的兼容性比较好:
/*兼容FF/IE9/IE8/IE7/IE6*/
function iframeResize(iframe) {
        try {
            //var iframe = document.getElementById("contentFrame"); //("contentFrame");
            var idocumentElement = iframe.contentWindow.document.documentElement;
            if (idocumentElement.scrollHeight > 560) {
                iframe.height -= 5;
                iframe.height = idocumentElement.scrollHeight;
            }
            else {
                iframe.height = 560;
            }
        }
        catch (e) {
            window.status = 'Error: ' e.number '; ' e.description;
        }
    }
