如何使用angularjs值替换css类值
How to replace css class value using angularjs values?
我现在有一个问题，无法使我的css值动态化。我有这种代码但不起作用
<style>
.panel-primary {
background-color:{{myColorPanel}}
}
</style>
我从这个链接看到了这篇文章
如何使用 AngularJS 动态创建 CSS 类
我不知道我在那里犯了什么错误，它没有奏效。
任何人都有解决我问题的替代方法。
我只想使引导面板以自定义颜色，我不想在我使用的每个面板中放置ng-class或ng-style，因为它太多了。
任何人有想法请告诉我。

我在下面提供了一个简单的示例，说明如何切换类，而不是直接修改类，但这不是一个非常典型的过程。
function MyCtrl($scope) {
$scope.myClass = 'blue'
}.blue { color: blue }
.red { color: red }<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app ng-controller="MyCtrl">
<h2 ng-class="myClass" ng-click="myClass = myClass == 'blue' ? 'red' : 'blue'">Click Me!</h2>
</div><html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.9/angular.min.js"></script>
<script>
angular.module("myApp",[]).controller("myController",function($scope){
$scope.name="sagar";
$scope.myColorPanel ="green";
$scope.colorChange=function(color){
$scope.myColorPanel =color;
}
});
</script>
</head>
<body ng-app="myApp" ng-controller="myController">

.panel-primary {

<button ng-click="colorChange('yellow')">Yellow</button>

</html>希望对您有所帮助..
现在我发现了真正的问题。我使用的angularjs版本不支持Angularjs的风格。由于它是一个现有的系统，所以使用的angularjs是旧版本。我以前使用的版本是1.2x然后我将其更新到较新版本(1.5x(，我使用的所有代码现在都可以工作。非常感谢你们的所有努力。我知道我的错没有意识到angularjs的版本，但非常感谢你。
解决方案正在从旧版本更改为新版本。
如果您希望它使用AngularJs工作，ng-class是最佳选择。您可以查看这篇文章。希望这能为您提供问题的解决方案。
我认为它应该有效。
可能还有其他地方正在设置.panel-primary的背景颜色。
您正在使用引导程序，对吗？确保你的自定义 CSS 是在引导程序的 CSS 之后加载的。
将样式标签放在控制器中，而不是放在 head 标签中，如下所示
<body ng-controller="MainCtrl">
Background of div is <input ng-model="name">
<style>
.p { background-color: {{name}}; }
</style>
<div class="p">dddd</div>
</body>
