问题 Like jQuery, How can I add dynamic rows to a table with form elements in a button click using angularjs and How to differentiate these form elements like array name in normal jquery submit. <tr> <td style="text-align:center">1</td> <td> <input type="text" class="form-control" required ng-model="newItem.assets"> </td> <td> <select ng-model="newItem.type" class="form-control"> <option value="Rent" ng-selected="'Rent'">Rent</option> <option value="Lease">Lease</option> </select> </td> <td>

问题 I have a need for inheriting scope from a parent controller in a directive. I don't necessarily want to leave scope: false. I also don't necessarily want to use an isolated scope, because it requires a lot of work to get the values I do care about linked properly (think lots of values in a parent controller). Does it make sense to use scope:true in my directive if I want to update parent scope? <div ng-controller="MyCtrl"> Hello, {{name}}! <my-directive></my-directive> </div> var myApp =

问题 This question already has answers here : What is the difference between '@' and '=' in directive scope in AngularJS? (18 answers) Closed 5 years ago . Creating an isolate scope inside a directive lets us map the outer scope to the inner scope . We have seen six different ways to map to attrbutes: =attr &attr @attr = & @ What do each of these scope mapping options do? 回答1: This can be confusing but hopefully a simple example will clarify it. First, let's separate model bindings from behaviors.

问题 var theApp = angular.module('theApp', []); var app = angular.module('theApp', ['ui.bootstrap']); app.controller('MenuSideController', ['$scope','SnazzyService','$modal','$log', function($scope, SnazzyService, $modal, $log) { $scope.user.zoomlvl = '2'; }]); I have the above controller and it sets a $scope which I can only ever access the values from inside. But I seen somewhere that using the below I would be able to access the $scope but when I console.log($scope) the $scope.user.zoomlvl it

问题 I have a $scope.myData object that contain a chunk of data. What i am trying to do is display the data but filter out the nulls and empty strings: $scope.myData = [ { "ID" : "001", "Message" : "test test test test" }, { "ID" : "002", "Message" : "test test test test" }, { "ID" : "003", "Message" : "test test test test" }, { "ID" : "004", "Message" : "test test test test" }, { "ID" : "005", "Message" : " " }, { "ID" : "006", "Message" : "test test test test" }, { "ID" : "007", "Message" :

问题 I'm using Typescript 2.1(developer version) to transpile async/await to ES5. I've noticed that after I change any property which is bound to view in my async function the view isn't updated with current value, so each time I have to call $scope.$apply() at the end of function. Example async code: async testAsync() { await this.$timeout(2000); this.text = "Changed"; //$scope.$apply(); <-- would like to omit this } And new text value isn't shown in view after this. Is there any workaround so I

问题 I'm trying to find out how I can stop a DOM element from binding data from the scope in angular. I know that you could do this with if statements and all, but is there a genuine & permanent way to stop binding a element in angular but keep the content that was added? So say i have this <div ng-bind=​"content" class=​"ng-binding">​Welcome​</div>​ And i change the model so that the div changes to this. <div ng-bind=​"content" class=​"ng-binding">​Welcome​ World</div>​ Then I click the button

问题 I am confused about when controllers get instantiated. Also, how do controllers gets instantiated when nesting states. I might be confused how scope gets attached to view and controller, that is, if every view gets its own controller and scope or do they share the same scope. Can someone please explain when controllers get instantiated? Under nested routes do all the views share one controller and scope? What happens when I switch states and go back to a state does another controller get

问题 Angular noob here. I am creating a directive to recursively display a tree of questions and sub questions. I am using a link in the template which calls a function within the scope.
