写在前面
最近在通过angularjs将数据绑定到前端，其中也涉及到很多新的东西，一些效果还是很有必要实现的。在使用中发现ng-class，ng-class-even、ng-class-odd的使用，对列表的操作非常方便，就在这里记录一下。

[Angularjs]ng-select和ng-options
一个例子
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" ng-app="myapp">
<head>
<title>class</title>
<script src="JS/angular.min.js"></script>
<script src="JS/angular-route.min.js"></script>
<script>
var app = angular.module('myapp', []);
app.controller('ColorController', function ($scope) {
$scope.users = [{ id: 1, name: 'wolfy', age: 20 }, { id: 2, name: 'wolfy2', age: 20 }, { id: 3, name: 'wolfy3', age: 20 }];
});
</script>
<style>
.main {
border: 1px solid #0094ff;
width: 100%;
} .list {
margin: 8px auto;
width: 90%;
text-align: center;
} .even {
background-color: lightgray;
} .odd {
background-color: lightgreen;
}
</style>
</head>
<body>
<div ng-class="'main'" ng-controller="ColorController">
<h2>示例一</h2>
<table ng-class="'list'" border="1" cellpadding="0" cellspacing="0">
<tr>
<th>ID</th>
<th>姓名</th>
<th>年龄</th>
</tr>
<tr ng-repeat="user in users" ng-class-even="'even'" ng-class-odd="'odd'" >
<td>{{user.id}}</td>
<td>{{user.name}}</td>
<td>{{user.age}}</td>
</tr>
</table>
<h2>示例二</h2>
<table ng-class="'list'" border="1" cellpadding="0" cellspacing="0">
<tr>
<th>ID</th>
<th>姓名</th>
<th>年龄</th>
</tr>
<tr ng-repeat="user in users" ng-class="($index+1)%2==0?'even':'odd'">
<td>{{user.id}}</td>
<td>{{user.name}}</td>
<td>{{user.age}}</td>
</tr>
</table>
</div>
</body>
</html>
总结
这里需要注意在使用ng-class,ng-class-even,ng-class-odd时，需为类样式加上单引号，不然不起作用。
