angular中如何定义全局变量 如何使用Angular Js声明全局变量？

I want a variable that can be used in all the controllers but don't want to create a service for it .Is it possible in angular js?

解决方案

You can make use of constants or values.

Constants

var app = angular.module('myApp', []);

app.constant('appName', 'Application Name');

app.controller('TestCtrl', ['appName', function TestCtrl(appName) {

console.log(appName);

}]);

Values

var app = angular.module('myApp', []);

app.value('usersOnline', 0);

app.controller('TestCtrl', ['usersOnline', function TestCtrl(usersOnline) {

console.log(usersOnline);

usersOnline = 15;

console.log(usersOnline);

}]);
