安裝cordova掃碼插件

cordova plugin add https://github.com/phonegap/phonegap-plugin-barcodescanner.git

然后在要頁面上添加調(diào)用的按鈕

<div ng-controller="erweimaCtrl">
    <button ng-click="erweima()">掃描二維碼</button>
</div>

然后在控制器里面寫調(diào)用的方法

angular.module('app').controller('erweimaCtrl', erweimaCtrl);
    erweimaCtrl.$inject = ['$scope'];
    function erweimaCtrl($scope) {
        //二維碼
        $scope.erweima = ()=> {
            cordova.plugins.barcodeScanner.scan(
                function(result) {
                    //掃碼成功后執(zhí)行的回調(diào)函數(shù)
                    alert("收到一個二維碼\n" +
                        "掃碼文字結(jié)果: " + result.text + "\n" +
                        "格式: " + result.format + "\n" +
                        "是否在掃碼頁面取消掃碼: " + result.cancelled);
                },
                function(error) {
                    //掃碼失敗執(zhí)行的回調(diào)函數(shù)
                    alert("Scanning failed: " + error);
                }, {
                    preferFrontCamera: true, // iOS and Android 設(shè)置前置攝像頭
                    showFlipCameraButton: true, // iOS and Android 顯示旋轉(zhuǎn)攝像頭按鈕
                    showTorchButton: true, // iOS and Android 顯示打開閃光燈按鈕
                    torchOn: false, // Android, launch with the torch switched on (if available)打開手電筒
                    prompt: "在掃描區(qū)域內(nèi)放置二維碼", // Android提示語
                    resultDisplayDuration: 500, // Android, display scanned text for X ms. 
                                            //0 suppresses it entirely, default 1500 設(shè)置掃碼時間的參數(shù)
                    formats: "QR_CODE", // 二維碼格式可設(shè)置多種類型
                    orientation: "portrait", // Android only (portrait|landscape), 
                                             //default unset so it rotates with the device在安卓上 landscape 是橫屏狀態(tài)   
                    disableAnimations: true, // iOS     是否禁止動畫
                    disableSuccessBeep: false // iOS      禁止成功后提示聲音 “滴”
                }
            );
        }
    }
