Angularjs切换网站配色模式简单示例2(切换body元素的class）

一个网站可以有多种配色方案，例如正常模式，夜间模式等。

简单示例一个通过点击toggle 按钮，切换body元素的class，达到切换配色模式的angularjs小app。

1. Live范例可以在以下Codepen网址查看： http://codepen.io/ChristyWang/pen/NPxNMx

2. Toggle button源代码由以下网站生成：https://proto.io/freebies/onoff/

3. 主要文件有两个：index.html和main.css。

index.html文件代码如下：

<!DOCTYPE html>
<html><head><link rel='stylesheet' type='text/css' href='main.css'><script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.10/angular.min.js"></script><script>var myApp = angular.module('App', []);myApp.controller('AppController',function($scope) {<span style="white-space:pre">	</span>//默认lightswitch关闭$scope.lightswitch = 'off';$scope.switchTheme = function() {var checkProperty = document.getElementById('myonoffswitch').checked;//如果toggle button被点击，body元素class设为“on”if (checkProperty) {$scope.lightswitch = 'on';} //如果toggle button再次被点击，body元素class设为“off”else {$scope.lightswitch = 'off';}}});</script>
</head><body ng-app='App' ng-controller='AppController' ng-class="lightswitch"><div class="onoffswitch"><input type="checkbox" name="onoffswitch" class="onoffswitch-checkbox" id="myonoffswitch" ng-click="switchTheme()"><label class="onoffswitch-label" for="myonoffswitch"> <span class="onoffswitch-inner"></span><span class="onoffswitch-switch"></span></label></div><p class='p1'>test line 1</p><p class='p2'>test line 2</p>
</body></html>

main.css文件代码如下：

 /*for light swtich*/.off p {color: red;
}body.on{background-color:grey;
}.on p {color: blue;
}/*for the toggle button*/
.onoffswitch {position: relative; width: 67px;-webkit-user-select:none; -moz-user-select:none; -ms-user-select: none;
}
.onoffswitch-checkbox {display: none;
}
.onoffswitch-label {display: block; overflow: hidden; cursor: pointer;border: 2px solid #999999; border-radius: 20px;
}
.onoffswitch-inner {display: block; width: 200%; margin-left: -100%;-moz-transition: margin 0.3s ease-in 0s; -webkit-transition: margin 0.3s ease-in 0s;-o-transition: margin 0.3s ease-in 0s; transition: margin 0.3s ease-in 0s;
}
.onoffswitch-inner:before, .onoffswitch-inner:after {display: block; float: left; width: 50%; height: 22px; padding: 0; line-height: 22px;font-size: 14px; color: white; font-family: Trebuchet, Arial, sans-serif; font-weight: bold;-moz-box-sizing: border-box; -webkit-box-sizing: border-box; box-sizing: border-box;
}
.onoffswitch-inner:before {content: "ON";padding-left: 10px;background-color: #0064D2; color: ;
}
.onoffswitch-inner:after {content: "OFF";padding-right: 10px;background-color: #F0F0F0; color: #999999;text-align: right;
}
.onoffswitch-switch {display: block; width: 18px; margin: 2px;background: #FFFFFF;border: 2px solid #999999; border-radius: 20px;position: absolute; top: 0; bottom: 0; right: 41px;-moz-transition: all 0.3s ease-in 0s; -webkit-transition: all 0.3s ease-in 0s;-o-transition: all 0.3s ease-in 0s; transition: all 0.3s ease-in 0s; 
}
.onoffswitch-checkbox:checked + .onoffswitch-label .onoffswitch-inner {margin-left: 0;
}
.onoffswitch-checkbox:checked + .onoffswitch-label .onoffswitch-switch {right: 0px; 
}
