问题描述

我正在使用javascript从url下载多个文件.

I am using the javascript to download multiple file from url.

它对于Firefox和谷歌浏览器都可以正常工作，但不适用于ie和edge

我使用了以下代码.

    var downloadUrl = report
    setTimeout(function() {
        var a = document.createElement('a');
        a.href = downloadUrl;
        a.target = '_parent';
        if ('download' in a) {
            a.download = downloadUrl;
        }

        (document.body || document.documentElement).appendChild(a);
        if (a.click) {
            a.click(); // The click method is supported by most browsers.
        } 
        a.parentNode.removeChild(a);
    }, 500);
});
