使用Angularjs从JSON获取领域 [英] Getting fields from JSON using Angularjs

问题描述

这是一个很简单的问题，但我正在写的应该显示用户的信息的网页。将有姓名，ID，角色等领域我想写的，我从数据库中获得JSON setter和getter方法​​。例如，如果我得到一个JSON，我想获取和显示名称字段中，我如何写angularJS此getter方法​​从$资源服务得到JSON之后？

This is a very simple question but I'm writing a webpage that's supposed to display the user's information. There will be fields of name, id, role, etc. I want to write setter and getter methods for the JSON that I receive from the database. For example, if I get a JSON and I want to get and display the name field, how would I write this getter method in angularJS after getting the JSON from a $resource service?

这是的JSON会怎样看一个例子：

This is an example of how the JSON would look:

[{"name": "Jason"
  "date of birth": "february 23, 2985"
  ....
 }]

同样，我只是想知道如何写一个getter方法​​，如果我想获得的名称字段。

Again, I just want to know how to write a getter method if I wanted to get the name field.

推荐答案

应该是一样的JavaScript。

Should be just like javascript.

var result = [{"name": "Jason"
  "date of birth": "february 23, 2985"
  ....
 }];

var firstResultsName = result[0].name;

但我注意到，你给结果的问题。你需要一个逗号分隔每个属性之后。

But i noticed a problem with the result that you gave. You need a comma after each property.

[{"name": "Jason", <<-- this comma is necessary to work correctly.
"date of birth": "february 23, 2985",  <<-- and this one.

请确保您有逗号为所有，但最后一个属性。

make sure you have commas for all but the last property.
