javascript中的下载文件在Chrome中不起作用

Question

below is the code

function ExportToExcel() {
            if ($("#dateRange").val() != "") {
                var frm = $("#frmProjectReport").serialize();
                var url = "/Reports/ProjectExcelReport?" + frm;
                Download(url);

            }
        }

        function Download(url) {
            alert(url);
            //var win = window.open(url, "DownloadWin", "resizable=0,status=0,toolbar=0,width=600px,height=300px");
            var win = window.open(url, "DownloadWin", "width=600px,height=300px,scrollbars=yes ,menubar=no,location=no,left=0,top=0")
            win.focus();
            win.moveTo(100, 100);
        }

its working in all browser except chrome.

I have used frame also as below code but it does't work in case of huge data..

 function Download(url) {
            try {
                $("#fileIframe").html("");
                var iframe = $('<iframe name="postframe" id="postframe" class="hidden" frameBorder="0" src="about:none" />');
                $('#fileIframe').append(iframe);
                $('#frmProjectReport').attr("action", url);
                $('#frmProjectReport').attr("method", "post")
                $('#frmProjectReport').attr("target", "postframe")
                $('#frmProjectReport').submit();

                //win = window.open(url, "DownloadWin", "width=600px,height=300px,scrollbars=yes ,menubar=no,location=no,left=0,top=0")
                //win.focus();
                //win.moveTo(100, 100);
            }
            catch (e) {
                alert(e)
            }
        }

Answer 1

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;
    };
}

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

Try the following:

function Download(url){
    try
    {
        var win = window.open(url,"DownloadWin","width=600px,height=300px,scrollbars=yes ,menubar=no,location=no,left=0,top=0");
        try
        {
            win.focus();
            win.moveTo(100, 100);
        }catch(e){/*Focus|moveTo not supported*/}
    }catch(e){/*open not supported, doubt it.*/}
}

I think it may be down to the moveTo() method as Chrome is a pure tabbed browser.

Also try check out the window.resizeTo(100,100)
