Question

JSON：

$scope.results=[
    {
        id: 1,
        name: null,
        class: "First"
    },
    {
        id: 2,
        name: John,
        class: "First"
    },
    {
        id: 3,
        name: Mary,
        class: "Second"
    },
    {
        id: 4,
        name: null,
        class: "Third"
    }

]

HTML：

 <div class="col-md-6 form-group" data-ng-repeat="item in results| filter:{name:'!null'}">{{item.name}}</div>

我想过滤掉name值null的数据。我的代码出了什么问题？

Answer 1

通过添加这段代码来解决它：

 <div class="col-md-6 form-group" data-ng-repeat="item in results| filter:{name:'!!'}">{{item.name}}</div>

$scope.results=[
{
    id: 1,
    name: null,
    class: "First"
},
{
    id: 2,
    name: "John",
    class: "First"
},
{
    id: 3,
    name: "Mary",
    class: "Second"
},
{
    id: 4,
    name: null,
    class: "Third"
}
];

ng-repeat过滤器不过滤掉空值
