angularjs-scope

问题 First of all, I have read so much info you all share about communication between controllers, that I'm now so confused about the BEST way to do it. I understand I should use service, but don't really know what it means from the examples you all wrote. Here is my scenario: Left side of my page I have a side bar with a simple folder/files tree. I have used angular Tree Component and it works great for me: http://jimliu.github.io/angular-ui-tree/ On the right side of the page, I have a view that

问题 Having these two files: HTML: <form name="registrationForm" ng-submit="registerUser()"> ... </form> JS (inside the Angular controller): $scope.registrationForm.confirmPassword.$setValidity("PasswordsMatch", $scope.validation.doPasswordsMatch); I get the error that Cannot read property 'confirmPassword' of undefined This leads me to believe that I have no access to the form registrationForm in the controller. Based on this (https://docs.angularjs.org/api/ng/type/ngModel.NgModelController) I

问题 if i get the column data like this with no space in between $scope.gridOptions.data = [{"name":"rasheedsyedabdulhameed"}]; and this is my gridoptions $scope.gridOptions = { columnDefs: [ { field: 'name' }, { field: 'name' }, { field: 'name' } ], enableGridMenu: true, enableSelectAll: true, exporterCsvFilename: 'myFile.csv', exporterPdfDefaultStyle: {fontSize: 9}, exporterPdfTableStyle: {margin: [30, 30, 30, 30]}, exporterPdfTableHeaderStyle: {fontSize: 10, bold: true, italics: true, color:

问题 I'm not able to send the complete form data using ng-submit.I'm able to send the data containing even name, event status, trigger event and relay state. The data of the appended div is being sent as undefined.Thankyou var app = angular.module('demo', []); app.controller("ruleCtrl", ['$scope', '$http', function($scope, $http) { jQuery(document).ready(function() { jQuery("#condition").click(function(e) { e.preventDefault(); jQuery('#shw').append(jQuery('.hiddenRule').clone().removeClass(

问题 What is the best way to share some data across all controllers and scopes of my Single page application ? Let say i have a small set of data I want to be able to access everywhere, and I don't want to query the database every time I need it. 回答1: Shared data services seems to be the best aproach for your case. There is $rootScope as a global scope, but, $rootScope shoudn't be used for such thing due to performance issues. $rootscope is part of angular digest cycle, so when you add something

问题 I just started with angularJS and I have a question: How can I access a variable defined with $rootScope in a templateUrl function? Here is my code: myApp.config(['$routeProvider', function($routeProvider, $rootScope) { $routeProvider. when( '/', { templateUrl: 'partials/login.html', controller: 'loginCtrl' }). when( '/home', { templateUrl: function($rootScope){ console.log($rootScope.utilisateur.user.role_id); if ($rootScope.utilisateur.user.role_id==2){ return 'partials/home.html'; } else

问题 One of the things that different Angular learning materials seem to be doing differently is passing variables. What is the difference between using $scope or the "someCtrl as some" syntax? What are the advantages? Should I stick with always using one of them or there are certain scenarios when using one of them is better than the other? 回答1: Todd Motto has some very good articles on this! Digging into Angular’s “Controller as” syntax A better way to $scope, angular.extend, no more “vm = this”

问题 I'm working with the Soundcloud JS SDK to bring my Soundcloud favorites into a simple Angular app. I wasn't able to get the user favorites to import in correctly until I used $scope.$apply . function TopListCtrl($scope, $http, $modal) { $scope.getData = function(sc_user) { SC.get('/users/'+ sc_user +'/favorites', {limit: 200}, function(tracks){ $scope.$apply(function() { if (Object.getOwnPropertyNames(tracks).length > 1) { $scope.likes = tracks; $scope.sortField = 'like.favoritings_count';

问题 I created a plugin for my phonegap app, which calls a native android "DatePicker" controll. The DatePicker is invoked in this way: There is a checkbox on the view. When the user check's the checkbox, I invoke the DatePicker. After selecting a date and pressing confirm, an event is fired an I get the date selected. The problem is, inside this event, I don't have the $scope. Even though I try to set it and it does not get updated. I imagine that this happen because the $scope is not in the

问题 This is the directive that I wanna build: module.directive('templater', function () { return { restrict: 'A', replace: true, templateUrl: function (element, attrs) { return attrs.templater; } }; }); but, as you may know, in this HTML: <div ng-repeat="item in items" templater="item.template"> </div> accessing attrs.templater simply gives item.template instead of the actual template url string. How do you access the data inside attrs.templater without going inside the linking function? I want
