復制代碼 代碼如下:

function AutoResize(iframe)
{
//firefox
if(iframe.contentWindow)
{
iframe.height = iframe.contentWindow.document.documentElement.scrollHeight;
iframe.width = iframe.contentWindow.document.documentElement.scrollWidth;

}
//IE
else if(iframe.contentDocument) {

iframe.height = iframe.contentDocument.width;
iframe.width = iframe.contentDocument.height;
}
}

復制代碼 代碼如下:

var tdObj = document.getElementById('ifrtd');
tdObj.innerHTML = ' QQ動態加載中 ... ';

var iframe = document.createElement("iframe");
iframe.src = 'http://www.zbphp.com/';

if (iframe.attachEvent){

//iframe.attachEvent("onload",AutoResize.call(iframe)); #報錯
iframe.attachEvent("onload", function(){
AutoResize(iframe);
});
} else {

//iframe.onload = AutoResize.call(iframe);#報錯不支持
iframe.onload = function(){
AutoResize(iframe);
};
}

tdObj.innerHTML = '';
tdObj.appendChild(iframe);
