带颜色的简单角度js示例 [英] Simple angular js example with colors
问题描述
我正在按照教程
Tryit Editor v3.1 [ ^ ]
我已将$ rootscope更改为第一个控制器的范围。但现在它不会列出颜色。
应该是：
蓝色
红色
红色，我做了更改后。
<！DOCTYPE html>
< html>
< script src =https://ajax.googleapis.com/ajax/libs/angularjs/1.4。 8 / angular.min.js>< / script>
< body ng-app =myApp>
< p> rootScope最喜欢的颜色：< / p>
< h1> {{color}}< / h1>
< div ng-controller =myCtrl>
< p>控制器最喜欢的颜色范围：< / p>
< h1> {{color}}< / h1>
< / div>
< p> Scope最喜欢的颜色是：< / p>
< h1> {{color}}< / h1>
< script>
var app = a ngular.module（'myApp'，[]）;
app.run（函数（$ scope）{
$ scope.color ='blue';
}）;
app.controller（'myCtrl'，函数（$ scope）{
$ scope.color =red;
}）;
< / script>
< p>请注意，控制器的颜色变量不会覆盖rootScope的颜色值。< / p>

Tryit Editor v3.1[^]
I have changed $rootscope to scope for the first controller . but now it wont list the colors.
Should it be:
Blue
Red
Red , after i made the changes.
<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<body ng-app="myApp">
<p>The rootScope's favorite color:</p>
<h1>{{color}}</h1>
<div ng-controller="myCtrl">
<p>The scope of the controller's favorite color:</p>
<h1>{{color}}</h1>
</div>
<p>The Scope's favorite color is :</p>
<h1>{{color}}</h1>
<script>
var app = angular.module('myApp', []);
app.run(function($scope) {
$scope.color = 'blue';
});
app.controller('myCtrl', function($scope) {
$scope.color = "red";
});
</script>
<p>Notice that controller's color variable does not overwrite the rootScope's color value.</p>
