关于循环下载附件的问题解决

循环下载的时候不可以用window open ,因为window open 只能打开一次网址，不能多次打开

所以我们采用iframe的方式

 

    var count = 0;

        var downloadURL = function downloadURL(url)

        {

            var hiddenIFrameID = 'hiddenDownloader' + count++;

            var iframe = document.createElement('iframe');

            iframe.id = hiddenIFrameID;

            iframe.style.display = 'none';

            document.body.appendChild(iframe);

            iframe.src = url;

        }

 

 

 for (var i = 0; i < ids.length; i++) {

/*                window.open(YZSoft.$url(me, 'D_AServices.ashx?method=Delete&id=' +ids[i]),i)*/

                   downloadURL( YZSoft.$url(me, 'D_AServices.ashx?method=Delete&id=' + ids[i])); //循环调用上面的iframe，实现循环下载附件

                    }

 

如果只下载一个或者只打开一次可以用windowopen

   window.open(YZSoft.$url(me, 'D_AServices.ashx?method=DownFile') )
