在工作中，需要点击某个控件实现另外一个控件的效果（例如变色、是否显示等），在angularjs中，使用ng-class是个不错的选择。
下面是我写的例子，方便学习。
<!DOCTYPE html>
<html lang="zh-CN" ng-app="jiazhengApp">
<head>
<meta name="viewport" content="width=device-width,initial-scale=1,maximum-scale=1,user-scalable=no">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script src="../public/ionic/js/ionic.bundle.min.js"></script>
<script src="../public/js/jquery.min.js"></script>
<link rel="stylesheet" href="../public/ionic/css/ionic.css">
<title>tabs_ionic.html</title>
</head>
<style>
.color_red{
color:red;
}
.font_32px{
font-size: 32px;
}
</style>
<body ng-controller="myController">
<ion-toggle ng-model="colorClass" toggle-class="toggle-calm">Airplane Mode</ion-toggle>
<ion-toggle ng-model="fontClass" toggle-class="toggle-calm">Airplane Mode</ion-toggle>
<!--使用key - value的方式设置 -->
<div ng-class="{'color_red':colorClass,'font_32px':fontClass}">dsaf</div>
<br>
<!-- 通过对象数组 -->
<div ng-class="{true:'color_red font_32px',false:''}[colorClass]">456436</div>
<br>
<!-- 通过数据的双向绑定（不推荐） -->
<div class="{{myfont}} {{myColor}}">456436</div>
</body>
<script>
var app = angular.module("jiazhengApp",["ionic"],function() {
})
//默认控制器
.controller("myController",['$scope','$ionicPopover','$timeout',function($scope,$ionicPopover,$timeout){
$scope.isShow=true;
$scope.myfont = "font_32px";
$scope.myColor = "color_red";
}])
</script>
</html>
<ion-list show-delete="isEditor">
<ion-item ng-repeat="item in goodlists" >
<span class="float_left" addressID="{{item.id}}" roomID="{{item.rooms_id}}">{{item.residence_name}}{{item.blocks_name}}{{item.rooms_name}}</span>
<span class="float_right icon ion-ios-checkmark font_24" ng-class="{'color_3eb034':item.is_default==1}" ng-click="chooseItem($event,'{{item.id}}')"></span>
<span class="clear_both"></span>
<ion-delete-button class="ion-minus-circled" ng-click="onItemDelete(item,'{{item.id}}')"></ion-delete-button>
</ion-item>
</ion-list>
ng-class="{'color_3eb034':item.is_default==1}"
备注：判断item.is_default是否等于1，如果等于1就显示color_3eb034。
