My first angular!
<html ng-app>
<head>
<meta charset="utf-8">
<script src="angular.js"></script>
<script src="controllers.js"></script>
<style>
.selected {
background-color: lightgreen;
}
</style>
</head>
<body>
<div ng-controller=‘HelloController‘>
<input ng-model=‘greeting.text‘ />
<p>{{greeting.text}}, World</p>
</div>
<div ng-controller="CartController">
<div ng-repeat=‘item in items‘>
<span>{{item.title}}</span>
<input ng-model=‘item.quantity‘>
<span>{{item.price | currency}}</span>
<span>{{item.price * item.quantity | currency}}</span>
<button ng-click="remove($index)">Remove</button>
</div>
</div>
<form ng-controller="fundingController">
Starting: <input ng-change="computeNeeded()"
ng-model="funding.startingEstimate">
Recommendation: {{needed}}
<input ng-model="funding.me">
</form>
ng-change ng-submit 就像事件处理函数一样
<form ng-submit="requestFunding()" ng-controller="StartUpController">
Starting:
<input ng-change="computeNeeded()" ng-model="startingEstimate">Recommendation: {{needed}}
<button>Fund my startup!</button>
<button ng-click="reset()">Reset</button>
</form>
<div ng-controller=‘DeathrayMenuController‘>
<button ng-click=‘toggleMenu()‘>Toggle Menu</button>
<ul ng-show=‘menuState.show‘>
<li ng-click=‘stun()‘>Stun</li>
<li ng-click=‘disintegrate()‘>Disintegrate</li>
<li ng-click=‘erase()‘>Erase from history</li>
</ul>
<div/>
ng-showW为false相当于display none
<table ng-controller=‘RestaurantTableController‘>
<tr ng-repeat=‘restaurant in directory‘ ng-click=‘selectRestaurant($index)‘ ng-class=‘{selected: $index==selectedRow}‘>
<td>{{restaurant.name}}</td>
<td>{{restaurant.cuisine}}</td>
</tr>
</table>
</body>
</html>
