嘿伙计,所以我有以下代码,这是一个简单的求和函数,从html中获取3个值并添加它们,它在jsfiddle上运行得很好:
app.js
angular.module('calculator', [])
//=========================================================================
.controller('CalculatorCtrl', function ($scope) {
$scope.a = 1;
$scope.b = 1;
$scope.x = 1;
$scope.result = function () {
var answer = 0;
answer = $scope.a + $scope.b + $scope.x;
return answer;
}
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div id="calculator-div" ng-app="calculator" ng-controller="CalculatorCtrl">
<div class="row">
<div class="col" id="calculator-title">Calcular Y</div>
</div>
<div class="row">
<div class="col">
<label class="item item-input item-floating-label">
<input type="number" placeholder="{{a}}" ng-model="a">
</label>
</div>
<div class="col col-10 ion-arrow-right-b"></div>
<div class="col">
<label class="item item-input item-floating-label">
<input type="number" placeholder="{{x}}" ng-model="x">
</label>
</div>
</div>
<div class="row">
<div class="col">
<label class="item item-input item-floating-label">
<input type="number" placeholder="{{b}}" ng-model="b">
</label>
</div>
<div class="col col-10 ion-arrow-right-b"></div>
<div class="col">
<label class="item item-positive item-floating-label" id="result">
{{result()}}
</label>
</div>
</div>
</div>
这是我在Ionic中的代码: 的 HTML

</div>
</div>
</div>
<div class="row">
<div class="col">
<p>Si necesito {{x}} zanahorias para alimentar {{a}} conejos, ¿cuántas zanahorias necesito para

A= {{a}}
B= {{b}}
X= {{x}}
</div>
</div>
</ion-content>
</ion-pane>
</body>
</html>
这就是我的 app.js 的样子:
angular.module('calculator', ['ionic'])
.run(function ($ionicPlatform) {
$ionicPlatform.ready(function () {
// Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
// for form inputs)
if (window.cordova && window.cordova.plugins.Keyboard) {
cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
}
if (window.StatusBar) {
StatusBar.styleDefault();
}
});
})
//=========================================================================
.controller('CalculatorCtrl', function ($scope) {
$scope.a = 0;
$scope.b = 0;
$scope.x = 0;
$scope.result = function () {
var answer = 0;
answer = $scope.a + $scope.b + $scope.x;
return answer;
}
});
答案 0 :(得分:1)
将 ng-controller =&#34; CalculatorCtrl&#34; 移至ion-content指令,如下所示:
<ion-content ng-controller="CalculatorCtrl">
我已使用以下网址在浏览器和实时设备中对其进行了测试:
ionic serve
和
ionic run android -l -c -s
工作示例:http://plnkr.co/edit/cefQpR?p=preview
这是一个特定的离子框架问题。从技术上讲,如果要在ion-content指令中使用变量,则必须使用点表示法。所以不要使用原始变量,使用对象。此解决方案将与body标签中的控制器一起使用。
