什么是正确的JavaScript对象格式？
[英]What is the proper JavaScript object format?
I made an exercise about ng-repeat with AngularJS 1.x , everything goes well.
我用AngularJS 1.x做了关于ng-repeat的练习,一切顺利。
JavaScript:
var app = angular.module('myModule', []);
app.controller('myController', function() {
this.dishes = [
{
'name': 'CD',
'drink': 'wine',
'color': 'red'
},
{
name: 'vagetable',
drink: 'water',
color: 'blue'
},
{
'name': 'meat',
'drink': 'coffee',
'color': 'brown'
}
];
});
HTML:
<html lang="en" ng-app="myModule">
<head></head>
<body ng-controller="myController as myCtrl">
<div> {{myController.dishes}} </div>
<ul>
<li ng-repeat="dish in myCtrl.dishes">
<p> {{dish.name}} is my name.</p>
<p> {{dish.drink}} is something you can drink.</p>
<p> {{dish.color}} is the color I wear.</p>
<hr>
</li>
<p> {{myCtrl.theModelContent}}</p>
<input type='text' ng-model="myCtrl.theModelContent">
</ul>
</body>
</html>
I noticed that 'name': 'CD' works fine as well as name: 'vegetable'. What's the difference between these two?
我注意到'名字':'CD'和名字一样好:'蔬菜'。这两者有什么区别?

JSON is a wire format where everything is a string, thus the usual call of JSON.stringify for your JavaScript object literal. Whereas JavaScript object literals can have string or non-string keys. The short answer is having a string key in a JavaScript object literal is optional, while it is required in the JSON-formatted version of that object literal.
JSON是一种有线格式,其中所有内容都是字符串,因此通常调用JSON.stringify作为JavaScript对象文字。 JavaScript对象文字可以包含字符串或非字符串键。简短的回答是JavaScript对象文字中的字符串键是可选的,而在该对象文字的JSON格式版本中需要它。
