javascript - jQuery Ajax文件上传(jQuery Ajax File Upload)

Question

Can I use the following jQuery code to perform file upload using POST method of an ajax request ?

(我可以使用以下jQuery代码使用ajax请求的POST方法执行文件上传吗？)

$.ajax({
    type: "POST",
    timeout: 50000,
    url: url,
    data: dataString,
    success: function (data) {
        alert('success');
        return false;
    }
});

If it is possible, do I need to fill data part?
