这是我的第一个有角度的应用......我必须说我很惊讶框架是多么棒。任务是建立一个价格计算器,在选择州后应用州税。这就是我在JS中的一些东西
function testApp($scope){
$scope.quantity = 1;
$scope.price = 10.99;
$scope.states = [
{stateName:'--'},
{stateName:'New York',stateId: 'NY', tax: 0.5},
{stateName:'Pennsylvania', stateId: 'PA', tax: 0.3},
{stateName:'California', stateId: 'CA', tax: 0.6}
];
}
我的标记看起来像这样
<div ng-app="" ng-controller="testApp">
Quantity: <input type="number" max="5" ng-model="quantity"/>
Price: <span class="price">{{price|currency}}</span>
State:
<select>
<option ng-repeat="x in states" id="{{x.stateId}}">
{{x.stateName}}
</option>
</select>
<h2 id="greeting">Total: {{quantity*price|currency}}</h2>
</div>
我无法理解如何读取状态对象和更改的tax属性并将其传递给总计。也许很简单,我无法从概念上理解
这是我的小提琴

查看data-ng-options。你不应该建立这样的选择。这是更新的html:
<select data-ng-model="selectedState" data-ng-options="state as state.stateName for state in states">
