6、filter过滤器

filter只匹配要过滤的value值

初始数据：

city : [
    {
        name:'上海',py:'shanghai'
    },{
        name:'北京',py:'beijing'
    },{
        name:'四川',py:'sichuan'
    }
]

使用：

<!-- 结果：[{"name":"上海","py":"shanghai"}] -->
<p>{{data.city | filter:'上海'}}</p>
<!-- 结果：[] -->
<p>{{data.city | filter:'name'}}</p>
<!-- 结果：[{"name":"上海","py":"shanghai"},{"name":"北京","py":"beijing"}] -->
<p>{{ data.city | filter : {py:'g'} }}</p>

7、OrderBy过滤器

<!-- 结果：[{"name":"北京","py":"beijing"},{"name":"上海",{"name":"四川","py":"sichuan"}] -->
<p>{{data.city | orderBy : 'py'}}</p>
<!-- 结果：[{"name":"四川","py":"sichuan"},"py":"beijing"}] -->
<p>{{data.city | orderBy : '-py'}}</p>

8、json过滤器

var jsonString = $filter('json')($scope.data)
console.log(jsonString)

结果：

{

"message": "aBcDeF",

"city": [

{

"name": "上海",

"py": "shanghai"

},

{

"name": "北京",

"py": "beijing"

},

{

"name": "四川",

"py": "sichuan"
