$.fileDownload(url,{
    contentType: "text/csv",
    contentDisposition: 'attachment; filename=' +

即使我尝试使用javascript也不起作用

Even I tried with javascript it's not working

var a = document.createElement("a");
document.body.appendChild(a);
a.href = url;
fileName = url.split("/").pop();
a.download = fileName
a.click();
window.URL.revokeObjectURL(url);
a.remove();

推荐答案

您的JavaScript无法正常工作，可能是因为在添加href和download属性之前将a附加到了正文.

Your JavaScript does not work probably because you append a to body before you add href and download attributes.

在触发click

还要记住，这仅适用于具有相同来源URL的文件(

Also remember that this will only work on files with the same-origin URLs (Source).

此属性仅适用于相同来源的URL .

var a = document.createElement("a");
a.href = url;
fileName = url.split("/").pop();
a.download = fileName;
document.body.appendChild(a);
a.click();
window.URL.revokeObjectURL(url);
a.remove();
