问题 I am learning Angular. I am watching a 2 years old video, and I am trying to use route concept and using in view1.CShtml (Remember, its CShtml and not html, while in the video, he uses html). I also find it wierd that Views path starts as ~Views/View1.cshtml (Fair enough I have it in Views folder) on contrary to Partial/View1 where the video demonstrator has. Now, I do not understand what is this "~" for when I have similar directory structure like demonstrator. Also, sadly, the view1 is not

问题 I m working on module where I have check a condition for the visibility of a panel as if slected index of a dropdown is not equal to 0 or -1 than it will make visible to my panel else it will not. I am bit confused as how to get the selected index value of my dropdown using ng-select . I have shown my dropdown code below:- <div data-ng-app="CustomerNew" data-ng-controller="CreateCustomerCtrl as custom" ng-init= getFormData(); > <table> <tr> <td> <select id="accountselector" style="width: 100%

问题 I've created a directive for a select input to select a userId. The model binds from the directive to the rest of the view. However, when I set the id from the controller it doesn't seem to bind to select input in the directive. Controller: app.controller('MainCtrl', function($scope) { // set userId to willem's Id $scope.userId = 3; }); Directive: app.directive('selectUser', function() { return { restrict: 'E', scope: { ngModel: '=' }, controller: function($scope) { $scope.users = [{ "id": 1,

问题 I'm using the services directive in Angularjs not factory and I need to populate a json file to local variable; /* Contains projects on the town */ leMaireServicess.service('cityService', function($http) { // JSON regions and cities loader this.cities = []; // initCities this.initCities = function() { this.cities = $http.get('data/census/cities.js').success(function(data) { return data; }); return this.cities; }; // Get city info this.getCity = function() { return this.cities; }; }); And in

问题 I have an ng-repeat that loops over an array of objects. At each loop the value 'template' & 'values' is initialised. The following version works and uses ng-include to load the template but it happens to be very very slow: <tr class="tableRowsDocs" ng-repeat="dbo in rows track by $index"> <div ng-init="values = dbo.get4(attobj.key); key = attobj.key; template = attobj.template || getAttributeTemplate(dbo.clazz + attobj.key);"> <div class="content" ng-include="template"></div> </div> </td> <

问题 In the angular scope, I have a huge object scope.a, and somehow I have another scope.b reference to it. I know angularJS uses dirty checking, so we should reduce the stuff inside scope. My question is, since a and b are essentially the same obj(reference). Will it have noticeable performance improvement if I manage to get rid of b, keep only one reference? 回答1: Just having something in the scope does not have any performance implications on the $digest cycle (See Integration with the browser

问题 I have an ng-repeater with a nested ng-repeater contained within it. In the nested repeater I am trying to track the parents $index value, this works fine. However, when I introduce an ng-if in the same element that has a reference to $parent.$index, the parents index is set to the child's index. Any ideas on this? The code is running here. An example would be, I click on index 1 of parent 0 and get index 1 parent 1 as indexes. JavaScript var myApp = angular.module('myApp', []); myApp

问题 Hey guys so I am simply trying to load data when my app starts. However, the view loads faster than the http request(of course). I want to refresh my view once my data has been properly loaded because that data defines my view. I've tried $rootScope.apply from inside the factory where I do my http request, and I also tried directly doing the http request in my controller again with $scope.apply, and neither one worked as they both gave me "$digest already in progress" Any idea how can I set

问题 As far as I know that basically scope is an instance of a controller. Every time I declare a controller scope will be available for that controller. But then why directive has scope in link function ? I didn't declare any controller for the directive. Then why link function has scope ? Any Idea ? 回答1: From the doc: scope: The scope to be used by the directive for registering watches. You may also be interested to see the differences between $scope and scope. All directives have a scope
