我尝试在我的指令启动时在链接函数中添加点击事件,但是当我尝试获取元素时它给了我空元素。
var link = function(scope, elem, attrs, controller){
console.log('WidgetId:' + controller.widget);
//Not working,
angular.element(elem[0].querySelectorAll('.widget-btn')).on('click', function(){
console.log('click event with querySelector');
});
// Directive element DOM
console.log(elem);
// That call return empty array, the PROBLEM is here
console.log(elem[0].querySelectorAll('.widget-btn'));
elem.on('click', function(e){
// But when I click in the directive, it returns the elements that I want
console.log(angular.element(elem[0].querySelectorAll('.widget-btn')));
});
scope.$on(scope.widget, function(){
console.log('directive get the controller message');
});
var widgetId = controller.widget;
function socketInit(){
socket.forward(widgetId, scope);
scope.$on('socket:'+ widgetId, function(){
console.log('Get socket msg');
});
};
socketInit();
}
return {
restrict: 'EA',
controller: controller,
// Our controller $scope will change for vm
controllerAs: 'vm',
// We set our widget info in the datasource.
scope: {
// After the configuration our datasource is accesible in the vm.datasource
datasource: '=',
addchanneluser: '&',
widget: '@'
},
bindToController: true,
templateUrl: '/angular-js/views/dashboard/directives/small/small.template.html',
link: link,
}
console.log(elem),它给了我指令元素 DOM,所以我想做的是在那个 DOM 中找到所有具有通道类的元素。我用 querySelector 执行,它给了我空数组。
但是,当所有指令在浏览器中收费时,我在指令控制台调用中单击是带有内容的。
我的问题是,它可能是一些初始化问题,或者是在链接功能之后对 querySelector 收费。
谢谢
