<my-dir myindex="$index" title="t1"></my-dir> app.directive('myDir', function () { return { restrict: 'E', scope: { myindex: '=', title: '@' }, template:'<div>{{myindex}}</div>', link: function(scope, element, attrs){ console.log('test', scope.myindex) } };})
参数绑定根据须要,提供如下几种功能:css

@

可使用ng-class命令,判断逻辑条件来动态的绑定css class给tag,基础语法为:code
option 1: function ctr($scope){ $scope.test =“classname”; } <div class=”{{test}}”></div> option 2: function Ctr($scope) { $scope.isActive = true; } <div ng-class="{true: 'active', false: 'inactive'}[isActive]"></div> option 3: function Ctr($scope) { } <div ng-class = "{option.selected == 'active' ? 'active' : 'inactive'}"></div>
也能够用angular.element (jqLite)来实现此功能:orm
var ele = document.getElementById(scope.subPhaseId); angular.element(ele).addClass('active');
angular.element接受String参数或DOM元素。也可直接用.css("k:v")绑定css style。element
