Angular针对iCheck封装单选/复选框指令

1. 构造icheck指令

var app = angular.module('myApp', []);
app.directive('icheck', ['$timeout', '$parse', function($timeout, $parse) {
    return {
      restrict: 'A',
      require: '?ngModel',
      link: function(scope, element, attr, ngModel) {
        $timeout(function() {
          var value = attr.value;
        
          function update(checked) {
            if(attr.type==='radio') { 
              ngModel.$setViewValue(value);
            } else {
              ngModel.$setViewValue(checked);
            }
          }
          
          $(element).iCheck({
            checkboxClass: attr.checkboxClass || 'icheckbox_square-grey',
            radioClass: attr.radioClass || 'iradio_square-grey'
          }).on('ifChanged', function(e) {
            if ($(element).attr('type') === 'checkbox' && attr['ngModel']) {
                scope.$apply(function() {
                    return ngModel.$setViewValue(e.target.checked);
                });
            }
            if ($(element).attr('type') === 'radio' && attr['ngModel']) {
                return scope.$apply(function() {
                    return ngModel.$setViewValue(value);
                });
            }
          });
    
          scope.$watch(attr.ngChecked, function(checked) {
            if(typeof checked === 'undefined') checked = !!ngModel.$viewValue;
            update(checked)
          }, true);
    
          scope.$watch(attr.ngModel, function(model) {
            $(element).iCheck('update');
          }, true);
          
        })
      }
    }
}]);

2. 声明数据模型

angular.module('myApp').controller(function($scope){
    $scope.sexList = [
        {
            id : 0,
            label : '男'
        },
        {
            id : 1,
            label : '女'
        },
        {
            id : 2,
            label : '其他'
        }
    ];    
    
    $scope.ruleList = [
        {
            id: 0,
            name : '信控'
        },
        {
            id: 1,
            name: '风控'
        },
        {
            id: 2,
            name: '客户经理'
        }
    ];
    
    $scope.selectSex = 0;   //选中的性别
    $scope.selectRule = {}  //选中的角色
});

3. 使用指令

    性别
    

        

            
            

                
                    {{item.label}}
                
            
        
        {{selectSex}}
    
    角色
    

        

            

                
                    {{item.name}}
                
            
        
        {{selectRule}}
