在添加页面实现一个checkbox的选择，然后在详情页面展示时，会自动选上之前被选中的。

2.添加页面

看官最好将这个代码复制过去看看效果。

<!DOCTYPE html><html><head><meta charset="utf-8"><script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script></head><body><div ng-app="myApp" ng-controller="myCtrl" >
    选择
    <div ng-repeat="item in list">
        <input type="checkbox" name="tagName" value="item.id" ng-click="select(item.id,$event)"> {{item.shortName}}
    </div>
    结果：{{result}}</div><script>    
    var app = angular.module('myApp', []);
    app.controller('myCtrl', function($scope) {
        //创建checkbox用的
        $scope.list=[{"id":1,"shortName":"张三"},{"id":2,"shortName":"李四"},{"id":3,"shortName":"王二"}];
        //存储已选
        $scope.result = [];
        //触发事件
        $scope.select = function(id,event){            
            console.log(event)//打印看看这是什么，有利于理解
            console.log(action)

            var action = event.target;
            if(action.checked){//选中，就添加
                if($scope.result.indexOf(id) == -1){//不存在就添加
                    $scope.result.push(id);
                }
            }else{//去除就删除result里
                var idx = $scope.result.indexOf(id);
                if( idx != -1){//不存在就添加
                    $scope.result.splice(idx,1);
                }
            }
        };
    });
</script></body></html>

3.详情展示

//假设添加页面的结果是：$scope.result = [3,2];

<!DOCTYPE html><html><head><meta charset="utf-8"><script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script></head><body>

<div ng-app="myApp" ng-controller="myCtrl" >
    回写时设置不可选，即设ng-disabled="true"
    <div ng-repeat="item in list">
        <input type="checkbox" name="tagName"  ng-checked="isSelected(item.id)" value="item.id" ng-disabled="true" > {{item.shortName}}
    </div>
    结果：{{result}}</div>

<script>    
    var app = angular.module('myApp', []);
    app.controller('myCtrl', function($scope) {
        //创建checkbox用的
        $scope.list=[{"id":1,"shortName":"张三"},{"id":2,"shortName":"李四"},{"id":3,"shortName":"王二"}];

        //在添加页面得到的结果
        //你会发现，顺序也不会影响结果
        $scope.result = [3,2];

        //被选中条件：ng-checked的结果为true
        $scope.isSelected = function(id){          
            return $scope.result.indexOf(id)!=-1; 
            //只要返回的结果为true，则对应的checkbox就会被选中，
            //所以我的思路是看存添加页面的结果里是否含有当前id即value值，
            //有就返回的true，没有就返回false
        };
    });
</script></body></html>

{"list":[{"content":"普通发票","type":1},{"content":"电子产品","type":2}]} 要传给后台的数据页面展示上面传type=1,下面增加的填type=2
