  • [AngularJS]ng-repeat指令要点

       ng-repeat指令要点


      1,基本格式,这里不作过多说明,需要的话查看文档

    <div  ng-repeat="item in someCollection [| someFilter:arg1:arg2 ...]">
      <span>{{$index}}</span><span>{{item.someProperty}}</span><span>{{item.someFunction()}}</span>
    </div>

      其中someXXX代表需要相应替换内容。$index是ng-repeat 内置变量,这是唯一一个数值型的,其他还有5个bool类型的:$first,$middle,$last,$even,$odd

      2,遍历map(字典)

    $scope数据的定义:

    $scope.item = {
        content1: 'content1',
        key: 'content1'
       date:'2005-12-01 12:32' }

    HTML代码定义:

    <div ng-repeat='(id,value) in item'>
        <span>{{id}}</span>&nbsp;<span>{{value}}</span>
    </div>

     输出结果:

        content1 'content1',
        key  'content1'
      date '2005-12-01 12:32'

      3,遍历数组

    $scope中数据定义:

    $scope.itemList=[{id:201,name:'abc',amount:100},{id:100,name:'zdb',amount:100},
    {id:10,name:'xxx',amount:200},{id:80,name:'231',amount:1020},
    {id:50,name:'ppp',amount:20},{id:1,name:'hhh',amount:1100}];

    HTML代码:

    <div class="row" ng-repeat="item in itemList">
      <span>{{item.id}}-{{item.name}}-{{item.amount}}</span>
    </div>

      4,ng-repeat-start和ng-repeat-end

    angular会重复 包括start和end两个指令所在元素在内的所有html代码块

    $scope中数据定义:

    $scope.itemList=[{id:201,name:'abc',amount:100,details:[{id:0,model:'#2',amount:34},
                                    {id:0,model:'#2',amount:66}]},
    {id:100,name:'zdb',amount:100,details:[{id:0,model:'#200',amount:34},
                           {id:1,model:'#203',amount:66}]
    },
    {id:10,name:'xxx',amount:200,details:[{id:0,model:'#211',amount:34},
                            {id:1,model:'#132',amount:166}]
    },
    {id:80,name:'231',amount:1020,details:[{id:0,model:'#112',amount:360},
                            {id:1,model:'#234',amount:660}]
    },
    {id:50,name:'ppp',amount:20,details:[{id:0,model:'#223',amount:14},
                          {id:2,model:'#212',amount:6}]
    },
    {id:1,name:'hhh',amount:1100,details:[{id:0,model:'#452',amount:340},
                          {id:1,model:'#225',amount:760}]
    }];

    HTML代码:

    <div class="row" ng-repeat-start="item in itemList">  
    </div>
      <div ng-repeat="sub in item.details">
        <span>{{item.id}}-{{item.name}}-{{item.amount}}</span>
      </div>
    <div ng-repeat-end>
      <div class='summary'><span>{{item.id}}-{{item.name}}-{{item.amount}}</span></div>
    </div>
