本文实例讲述了angular.fromJson与toJson方法用法。分享给大家供大家参考，具体如下：
AngularJS的angular.fromJson()方法可以把一个Json字符串中解析成一个对象，或对象数组：
<!DOCTYPE html>
<html ng-app="App">
<head>
<meta charset="UTF-8">
<title></title>
<script src="../js/angular.js"></script>
<script type="text/javascript">
angular.module("App", [])
.controller("parseController", function($scope)
{
$scope.parse = function()
{
var json = '{"name":"liSi", "password":"321"}';
var jsonArr = '[{"name":"zhangSan", "password":"123"},{"name":"liSi", "password":"321"}]';
var obj = angular.fromJson(json);
console.log(obj.name);
var objArr = angular.fromJson(jsonArr);
console.log(objArr[0].name);
console.log(objArr[1].password);
}
});
</script>
</head>
<body>
<div ng-controller="parseController">
<button ng-click="parse()">点击我！</button>
</div>
</body>
</html>
控制台打印的结果如下：
liSi zhangSan 321
相应地，能够从Json到对象，就能够从对象到Json:
var obj =
{
name:"liSi", password:"321"
}
var str = angular.toJson(obj, true);
console.log(str);
打印结果如下：
{
"name": "liSi",
"password": "321"
}
