要求:
我的代码:
var SessionManager = (function (my) {
function addUrl(urlHistory) {
if (!urlHistory) throw new TypeError('"urlHistory" is null or not defined');
if (!(urlHistory instanceof UrlHistory)) throw new TypeError('"urlHistory" is not an "UrlHistory" object');
$.ajax({
url: '/CollateralManagement/Session/AddUrl',
type: 'POST',
success: function (result) {
},
data: { __RequestVerificationToken: $('input[name=__RequestVerificationToken]').val(), model: urlHistory }
});
}
my.addUrl = addUrl;
return my;
})(SessionManager || {});
var UrlHistory = function (area, controller, view, params) {
if (params && !Array.isArray(params)) throw new TypeError('The variable "params" is not null and not an array');
var me = this;
me.Area = area;
me.Controller = controller;
me.View = view;
me.Params = Array.isArray(params) ? params : [];
};
UrlHistory.prototype.coucou = function () {
console.log(this);
};
UrlHistory.prototype.AddParam = function (key, value) {
this.Params.push({ "Key": key, "Value": value });
return this;
};
//I run the code with this exemple:
var uh = new UrlHistory("toto", "tata", "titi");
uh.AddParam("z", "z").AddParam("a", "a");
SessionManager.addUrl(uh);
我的对象看起来很棒: UrlHistory {Area:" toto",Controller:" tata",View:" titi",Params:Array [2]}
但是当我输入ajax方法时,我有这个错误:
未捕获的TypeError:无法读取属性' push'未定义的
我尝试过相同的调用ajax而不添加原型,而且一切正常。
当运行ajax函数时,我的2个方法被调用但是"这个"是" Window"而不是" UrlHistory"。

以下代码将调用函数something
var Test = function(){
this.name="Hello World";
}
Test.prototype.something = function(){
console.log(".... something has been called",this);
throw new Error("what is the stack?");
}
jQuery.post("",Object.create(new Test()))
这是因为jQuery代码中的following line检查对象成员是否是函数,如果是,它将调用该函数并使用结果值。
jQuery使用jQuery.param
将对象序列化为http post或获取参数,以便jQuery.param(new Test())
引发相同的错误。
您希望阻止jQuery调用该函数,但我在文档中找不到任何内容来覆盖序列化函数,但您可以在urlHistory类型中添加一个函数来转换为数据:
var urlHistory = function(){
this.name="Hello World";
}
urlHistory.prototype.something = function(){
console.log(".... something has been called",this);
throw new Error("what is the stack?");
};
urlHistory.prototype.toData = function(){
var ret = {};
//this works in your example but if nested objects have functions
// it may still fail
for ( prefix in this ) {
if(typeof this[ prefix ] !== "function" ){
ret[ prefix ] = this[ prefix ];
}
}
return ret;
}
console.log("..... working:",jQuery.param((new urlHistory()).toData()))
在您的情况下,您可以将toData
添加到urlHistory,然后在ajax调用中执行:model: urlHistory.getData()

我知道这个问题已经过时了,但这对我帮助很大,希望能帮到别人。
当通过ajax发送数据时,我只是编码并首先对其进行解码
var object //this is your object with a prototype
var send_data = $.parseJSON(JSON.stringify(object)); //this encodes and decodes
$.ajax({
url: '/someurl',
type: 'post',
data: send_data
})
