如何使用 ExtJS JSONReader 读取不可迭代参数

发布于 2024-11-29 01:26:21 字数 636 浏览 2 评论 0原文

我发送以下 JSON 结构：

{ "header": "Staff Name",
  "result":[
    {"firstname":"Leo","id":1,"lastname":"name"},
{"firstname":"Robert","id":2,"lastname":"name"}],
  "totalCount":4,
  "success":true}

在我的 JS 文件中，我定义 JSONReader 如下：

var resultReader = new Ext.data.JsonReader({
    root:'result',
    totalProperty: 'totalCount'                 
}, Ext.data.Record.create([                           
    {name: 'id'} ,
    {name: 'firstname'},
    {name: 'lastname'}
]));

这有效，我能够迭代结果数组。然而，我想要实现的是能够以某种方式读取在结构开头找到的参数“header”。

我应该如何定义 JSONReader 来存储这个参数，以及以后如何加载这个参数？

I am sending over the following JSON structure:

{ "header": "Staff Name",
  "result":[
    {"firstname":"Leo","id":1,"lastname":"name"},
{"firstname":"Robert","id":2,"lastname":"name"}],
  "totalCount":4,
  "success":true}

In my JS file I define the JSONReader as follows:

var resultReader = new Ext.data.JsonReader({
    root:'result',
    totalProperty: 'totalCount'                 
}, Ext.data.Record.create([                           
    {name: 'id'} ,
    {name: 'firstname'},
    {name: 'lastname'}
]));

This works and I am able to iterate over the result-array. However what I want to achieve is to somehow be able to read the parameter "header" found in the beginning of the structure.

How should I define the JSONReader to store this parameter, and how can I later load this parameter?
