Question

我有一个指令，用于监听点击事件并获取参数值，但所有3个值都在调试器中显示为param 1的值，其中param 2＆amp; 3未定义。

HTML

<div my-directive data-ng-click="(vm.id, vm.title, vm.name)"></div>

指令：

.directive('myDirective', ['config', function (config) {
    // ...
    link: function (scope, elem, attrs) {
      // ...
      // click event
      elem.bind('click', function () {
        attrs.$observe('onClick', function (param1, param2, param3) {
        // ...

html中的ng-click参数值应如何为指令单独拾取的值编写？

            var result2 = attrs.param2;
            var result3 = attrs.param3;
              .....
            if (result1 != undefined && result2 != undefined && result3 != undefined) {
                switch (result1) {
                 case "SampleA":
                  // call parent controller on directive's html page
                   scope.vm.MyCtrl1Function(result1, result2, result3);
                   break;
                       .................
                  }
              };
          });
      }]);
