以角度 2 更新对象的值答案

【问题标题】：Updating value of the object in angular 2以角度 2 更新对象的值
【发布时间】：2018-12-11 16:33:03
【问题描述】：

我必须在特定索引处更新我的对象的值名称属性。我有索引号和数组。这是我的代码，

this.menus.forEach(x => {
      let temp = this.menus.findIndex(function (item) {
                           return item.name == 'Cost Center';
                           });
     // this.menus.values[temp].name=this.newCC;
     this.menus[temp].name=this.newCC;
        console.log("menu temp",temp);

这是我的数组结构，数组(11)

0:{_id: "5acc9e6320a7d71ab8372120", name: "DashBoard", link:        "dashboard", icon: "fa fa-list", key: "dashboard", …}

2:{sequence: null, key: "my-saved-jobs", icon: "fa fa-file-text-o", link: "my-saved-jobs", name: "My Saved Jobs", …}

7:{sequence: null, key: "my-saved-files", icon: "fa fa-floppy-o", link: "my-saved-files", name: "My Saved Files", …}

8:{sequence: null, key: "product-list", icon: "fa fa-list", link: "product-list", name: "Product List", …}

9:{_id: "5acc9e6320a7d71ab8372119", name: "Deal Code", link: "deal- code", icon: "fa fa-university", key: "deal-code", …}

实际上我在编写代码时犯了一个错误，这段代码应该写在我们从后端获得响应的地方，即在成功响应的范围内。这是我的新代码，

this.httpService.save(UrlDetails.$getPaymentSetting, client)
            .subscribe(response => {
                 if (response.responseCode == 200) {
                      let paymentSetting = response.responseData;
                      console.log("client PAYMENT RESPONSE ",paymentSetting);
                       if( paymentSetting.paymentOption.customPayment.length != 0){
                           <------Some Code----->
                                      .
                                      .
                           this.menus.forEach(x => {
                               let temp1 = this.menus.findIndex(function (item) {
                               return item.name == 'Cost Center';
                               });

                               let temp2 = this.menus.findIndex(function (item) {
                               return item.name == 'Deal Code';
                               });
                        this.menus[temp1].name= this.newCC;
                        this.menus[temp2].name= this.newDC;

             });
                     }
            })
