我想使用javascript实现客户端可下载文件,并使用数据URI在客户端使用以下方式动态创建文件:
<a href="data:application/csv;charset=utf-8,Col1%2CCol2%2CCol3%0AVal1%2CVal2%2CVal3%0AVal11%2CVal22%2CVal33%0AVal111%2CVal222%2CVal333">Download CSV</a>但是,下载的文件没有名称。我在stackoverflow上看到了一些解决方案,其中可以使用“download”属性,但我需要支持旧浏览器,所以我不能使用它。

您可以很容易地根据您的需要修改这段代码:
//Generate a file name
var fileName = "List_";
//this will remove the blank-spaces from the title and replace it with an underscore
fileName += ReportTitle.replace(/ /g,"_");
//Initialize file format you want csv or xls
var uri = 'data:text/csv;charset=utf-8,' + escape(CSV);
// Now the little tricky part.
// you can use either>> window.open(uri);
// but this will not work in some browsers
// or you will not get the correct file extension
//this trick will generate a temp <a /> tag
var link = document.createElement("a");
link.href = uri;
//set the visibility hidden so it will not effect on your web-layout
link.style = "visibility:hidden";
link.download = fileName + ".csv";
//this part will append the anchor tag and remove it after automatic click
document.body.appendChild(link);
link.click();
document.body.removeChild(link);发布于 2016-01-06 17:03:09
a标记的download属性现在指定下载文件的名称:

看看下面的链接。它似乎允许您下载客户端生成的数据并指定文件名。
