Question

我已经通过一个新对象传递了AJAX参数，然后我将这个对象传递给了jQuery的$.ajax()。我遇到的问题是试图完全重置我的对象。我的意思是我知道有一种简单优雅的方式，我只是没有看到它。事实上，我认为现在，我根本无法完成它。有人可以通过一些帮助吗？

这是我正在做的事情的片段。

    var app{};

    var async = {};

    app.resetAjax = function(){
            app.async = {
                url: 'this/path/',
                dataType = 'JSON';
                type = 'GET';
            return app.async; //important, because i want to return it, this way. 
        }   
    };  

    //Then, come in later and set it up in another file
    async = app.resetAjax();
    async.type = 'POST';
    async.dataType = 'XML';
    async.headers : { ///defaults
        "SomethingWayWierd" : "hopeless", 
    };
    async.data = app.someOtherProp;
    async.timeout= 3000; //maybe one more tweak

    //then run the call somewhere
    $.ajax(async); //Now, this call MUST be XML, and the POST, not the default 'JSON' and 'GET'

所以，请注意，我重置的函数resetAjax();。这是我的问题。我将如何正确地重置它（即去除我的重置功能并用建议的东西替换它，更简单）。可能是像

这样简单的事情

app.async = new $.ajax();

或者

app.async = $.ajax();

这些对我来说不起作用，它们失败了，就像我最初在原始函数中所做的那样。

那么确保以前没有设置传递到我的自定义变量var中的正确方法是正确的方法，在下一轮，在SPA中？

我甚至试过这个：

    app.async = {
        accepts: null,  //default: depends on DataType) Type: PlainObject
        async: true, //boolean, true by default, set to false if you want to send synchronously
        beforeSend: null, //Type: Function( jqXHR jqXHR, PlainObject settings )
        cache: null, // (default: true, false for dataType 'script' and 'jsonp')
        complete: null, //Type: Function( jqXHR jqXHR, String textStatus )
        contents: null,  //Type: PlainObject
        contentType: null, // (default: 'application/x-www-form-urlencoded; charset=UTF-8')
        context: null, //Type: PlainObject
        converters: null, // (default: {"* text": window.String, "text html": true, "text json": jQuery.parseJSON, "text xml": jQuery.parseXML})
        crossDomain: null, //(default: false for same-domain requests, true for cross-domain requests)   Type: Boolean
        data: null, //{} //object, string ,array
        dataFilter: null, //Type: Function( String data, String type ) => Anything
        dataType: null, //'json', //'json', // string, what type of data do we want the server to send back?  there is no default on this, we can add one here if we need. JSON BROKE IT< DONT USE JSON AS DEFAULT
        error: null, //Type: Function( jqXHR jqXHR, String textStatus, String errorThrown ),  DEFINED in app.router. rsvpAjax
        global: true, //boolean, defaults to true, set to false for prevent global handlers like ike ajaxStart or ajaxStop from being triggeredl
        headers: null, //(default: {}) Type: PlainObject
        ifModified: false, //boolean, defaults to false, if set to true then allow request to be successful only if the response has changed since last request
        isLocal: null, //(default: depends on current location protocol)  Type: Boolean
        jsonp: null, //Type: String
        jsonpCallback: null, //Type: String or Function()
        method: null,  //  (default: 'GET') Type: String
        mimeType: null,  //Type: String, A mime type to override the XHR mime type.
        password: null,  //Type: String
        processData: null,  //  (default: true) Type: Boolean //set to false if you want to send the form as a dom element
        scriptCharset: null,  //Type: String, Sets the charset attribute on the script tag, only applies when the "script" transport is used (e.g., cross-domain requests with "jsonp" or "script" dataType and "GET" type).
        statusCode: null,  // (default: {})  Type: PlainObject
        success: null,  // Type: Function( Anything data, String textStatus, jqXHR jqXHR ), DEFINED in app.router. rsvpAjax
        timeout : 10000, //10000 is 10 seconds //number,  app.router.ajax.timeout = null; //number,
        traditional: null,  // Type: Boolean, Set this to true if you wish to use the traditional style of param serialization.
        type: 'GET', // (default: 'GET') Type: string,  the type of request to make
        url: null, //  (default: The current page)  Type: String
        username: null,  //Type: String
        xhr: null,   //(default: ActiveXObject when available (IE), the XMLHttpRequest otherwise) Type: Function().  This is the callback for creating the XMLHttpRequest object.
        xhrFields: null  //Type: PlainObject, An object of fieldName-fieldValue pairs to set on the native XHR object. For example, you can use it to set withCredentials to true for cross-domain requests if needed.
    };

并且可能会继续得到一个涓涓细流的错误效果，它开始说“接受：＆＃39;在我得到正确拨打的所有设置并且考虑到我不想维护的设置之前，我就不会“无效”。所以，我觉得我需要ajax.reset()或其他什么。

在代码中存在一个悬挂问题，以及一个全局问题。如果async是app的属性，则缩小范围。稍后，使用它作为属性，重置它，然后微调它，然后调用你的ajax。

<?php 

var app{};
app.async = {};

//add your defaults here
app.resetAjax = function(){
        app.async = {
            url: 'default/path',
            dataType = 'JSON',
            type = 'GET', 
            contentType: 'application/x-www-form-urlencoded; charset=UTF-8';
    }   
};  

//in your module adjust it when needed, then call it
app.resetAjax();
app.async.type = 'POST';
app.async.dataType = 'XML';
app.async.headers : { ///defaults
    "SomeWierdHeader" : "its value", 
};
app.async.data = app.someOtherProp;
app.async.timeout= 3000; //maybe one more tweak

//run it
$.ajax(app.async);

如何完全重置自定义AJAX对象？
