我試圖顯示一個日誌消息,當用戶點擊按鈕。而是這個錯誤顯示出來:
TypeError: $scope.scanBarcode is not a function
at new <anonymous> (controllers.js:8)
at Object.instantiate (ionic.bundle.js:18015)
at $controller (ionic.bundle.js:23417)
at Object.self.appendViewElement (ionic.bundle.js:59908)
at Object.render (ionic.bundle.js:57901)
at Object.init (ionic.bundle.js:57821)

at updateView (ionic.bundle.js:65400)
at ionic.bundle.js:65377
(anonymous) @ ionic.bundle.js:26799
這裏是我的controller.js代碼:
angular.module('app.controllers', [])
.controller('page4Ctrl', ['$scope', '$stateParams', function ($scope, $stateParams) {
$scope.scanBarcode() = function()
{
console.log("hello");
};
}])
,這裏是我的html代碼:
<ion-view title="Page1" id="page18">
<ion-content padding="true" class="has-header">
<button id="page4-button4" class="button button-positive button-block" ng-click="scanBarcode()">Scan</button>
<button id="page4-button5" class="button button-positive button-block">Display Scanned Data</button>
可能是什麼問題?
你應該定義'離子content'內的控制器。我認爲。 '' –
謝謝,錯誤仍然顯示出來。 –
