1.需求
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>
