这是我们使用IFRAME导出excel文件的方式:

Here is the way we export an excel file using an IFRAME:

function download(src){
    var ifr = document.createElement('iframe');
    ifr.style.display = 'none';
    document.body.appendChild(ifr);
    ifr.src = src;
    ifr.onload = function(e){
        document.body.removeChild(ifr);
        ifr = null;
    };
}

它适用于所有浏览器，并且具有不弹出窗口的优点.

It works in all browsers, and has the advantage of not popping up a window.
