我的MVC没有收到Json返回值 [英] My MVC does not receive Json return value

问题描述

我有一个代码:

公共JsonResult getDetailsProduct(字符串ID)
       {
           返回this.Json(new {detPro ="trung"});
       } 

和Json函数:

function showPMuaHang(pid) {
    var url = ''/ShoppingCart/'' + pid + ''/getDetailsProduct'';
    $.ajax({ type: "POST", url: url,
        success: function (data) {
            document.getElementById("popup_muahang").innerHTML = data.detPro;
        }
    })

我使用href呼叫Json:

<a onclick="#" href="javascript:showPMuaHang(''70'')">Mua hàng</a>

如果我在本地.../索引页面中单击"a"，Json返回"trung"，但是如果我从本地.../ShoppingCart/调用它，Json返回"trung"，但它显示未定义".

我正在用MVC编码网站.

解决方案

.ajax({type:"POST"，url:url， 成功:功能(数据){ document.getElementById("popup_muahang").innerHTML = data.detPro; } })

<a onclick="#" href="javascript:showPMuaHang(''70'')">Mua hàng</a>

如果我在本地.../索引页面中单击"a"，Json返回"trung"，但是如果我从本地.../ShoppingCart/调用，Json返回"trung"，但它显示未定义".

请按如下所示修改您的JavaScript函数:

function showPMuaHang(pid) {
           var url = ''/ShoppingCart/getDetailsProduct/'' + pid;

.ajax({ type: "POST", url: url, success: function (data) { document.getElementById("popup_muahang").innerHTML = data.detPro; } }) }

问题出在url-您的路径如下-

/ShoppingCart/'' + pid + ''/getDetailsProduct''

哪里pid-70
但您的动作或方法没有70.在网址"

getDetailsProduct

"中被视为"ID"

以下是正确的格式-

/ShoppingCart/getDetailsProduct/'' + pid

是-

/ShoppingCart/getDetailsProduct/70

它将进入ShoppingCartController并为pid = 70

搜索

getDetailsProduct

I have a code:

public JsonResult getDetailsProduct(string id)
       {
           return this.Json(new { detPro = "trung" });
       }

and Json function:

function showPMuaHang(pid) {
    var url = ''/ShoppingCart/'' + pid + ''/getDetailsProduct'';
    $.ajax({ type: "POST", url: url,
        success: function (data) {
            document.getElementById("popup_muahang").innerHTML = data.detPro;
        }
    })

And i use a href to call Json:

<a onclick="#" href="javascript:showPMuaHang(''70'')">Mua hàng</a>

If i click "a" in local.../Index page, Json return "trung" but if i call it from local.../ShoppingCart/, Json return "trung" but i it show "undefined".

I''m coding a website in MVC.

Hi,

Please modify your javascript function as follows :

function showPMuaHang(pid) {
           var url = ''/ShoppingCart/getDetailsProduct/'' + pid;

.ajax({ type: "POST", url: url, success: function (data) { document.getElementById("popup_muahang").innerHTML = data.detPro; } }) }

problem is with url - your path is as follows -

/ShoppingCart/'' + pid + ''/getDetailsProduct''

where pid - 70
but you dont have 70 as your action or method.In URL ''

getDetailsProduct

'' is treated as " ID "

Following is the right format -

/ShoppingCart/getDetailsProduct/'' + pid

which is -

/ShoppingCart/getDetailsProduct/70

It will goto ShoppingCartController and will serach for

getDetailsProduct

for the pid = 70
