Uncaught ReferenceError: angular is not defined - AngularJS not working

由 两盒软妹~` 提交于 2019-12-28 05:35:10
问题 I'm attempting to learn angular and I am struggling with a simple button click. I followed an example which has an identical code to the one below. The result I am looking for is for the button click to cause an alert. However, there is no response to the button click. Does anybody have any ideas? <html lang="en" ng-app="myApp" > <head> <meta charset="utf-8"> <title>My AngularJS App</title> <link rel="stylesheet" href="css/app.css"/> </head> <body> <div > <button my-directive>Click Me!<

How to detect browser using angularjs?

由 这一生的挚爱 提交于 2019-12-28 03:30:13
问题 I am new to angularjs. How can I detect userAgent in angularjs. Is it possible to use that in controller? Tried something like below but no luck! var browserVersion = int((/msie (\d+)/.exec(lowercase(navigator.userAgent)) || [])[1]); I need to detect IE9 specifically! 回答1: Like Eliran Malka asked, why do you need to check for IE 9? Detecting browser make and version is generally a bad smell. This generally means that you there is a bigger problem with the code if you need JavaScript to detect

How to understand the `terminal` of directive?

由 耗尽温柔 提交于 2019-12-27 16:40:29
问题 In this page: http://docs.angularjs.org/guide/directive Directive Definition Object terminal If set to true then the current priority will be the last set of directives which will execute (any directives at the current priority will still execute as the order of execution on same priority is undefined). I don't understand it well. What does current priority mean? If there are such directives: directive1 with { priority: 1, terminal: false} directive2 with { priority: 10, terminal: false}

Angularjs loading screen on ajax request

由 老子叫甜甜 提交于 2019-12-27 11:37:07
问题 Using Angularjs , I need to show a loading screen (a simple spinner) until ajax request is complete. Please suggest any idea with a code snippet. 回答1: Instead of setting up a scope variable to indicate data loading status, it is better to have a directive does everything for you: angular.module('directive.loading', []) .directive('loading', ['$http' ,function ($http) { return { restrict: 'A', link: function (scope, elm, attrs) { scope.isLoading = function () { return $http.pendingRequests
