angularjs ng-class学习笔记

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}"
