javascript - jQuery.ajax: TypeError: Property 'xhr' of object #

Question

I have a jquery.ajax object in which I want to substitute xhr. However executing the following code gives me an error:

TypeError: Property 'xhr' of object #<Object> is not a function

The relevant code is:

    var req = jQuery.ajaxSettings.xhr();
    req.upload.addEventListener('progress', calendar.check_progress, false);

    $.ajax({
        url: script_root + '_save_file/'+id+'/'+timestamp,
        type: 'POST',
        processData: false,
        contentType: false,
        data: fd,
        xhr: req,
        success: function(data){
            do_something();
        },
        error: function(data){
            console.log(data);
            do_something_else();
        }
    });

xhr以其他方式使用。请参阅文档：http ://api.jquery.com/jQuery.ajax/

xhr: 函数

默认值：ActiveXObject 可用时 (IE)，否则为 XMLHttpRequest

创建 XMLHttpRequest 对象的回调。可用时默认为 ActiveXObject (IE)，否则为 XMLHttpRequest。重写以提供您自己的 XMLHttpRequest 实现或对工厂的增强。

可能是你正在寻找类似的东西

xhr: function() {
    var xhr = $.ajaxSettings.xhr();
    xhr.upload.addEventListener('progress', calendar.check_progress, false);
    return myXhr;
},
