我对混合应用程序开发的概念很陌生，并且不习惯任何脚本语言(例如 javascript)。
我正在尝试通过 cordova 联系人选择器插件访问设备电话簿，但我没有收到任何错误，也没有实现所需的功能。
这是我调用插件 api 的 View 部分。

<body ng-app="emergency">
<ion-view title="My Profile - Emergency" ng-controller="SmsCtrl">
<ion-content overflow-scroll="true" padding="true" class="has-header">

<div class="spacer" style="width: 285px; height: 34px;"></div>

<div id="contactFetched"></div>
</ion-content>
</ion-view>
</body>
</html>
我编写的两个js文件是emergency.js和services.js
这是我的emergency.js，它由调用联系人选择器服务的 Controller 组成:-
// Ionic Starter App
// angular.module is a global place for creating, registering and retrieving Angular modules
// 'starter' is the name of this angular module example (also set in a <body> attribute in index.html)
// the 2nd parameter is an array of 'requires'
var finalContacts="";
var contactCount=0;
angular.module('emergency', ['ionic','ngCordova','NameService'])
.run(function($ionicPlatform) {
$ionicPlatform.ready(function() {
// Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
// for form inputs)
if(window.cordova && window.cordova.plugins.Keyboard) {
cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
}
if(window.StatusBar) {
StatusBar.styleDefault();
}
});
})
.controller('SmsCtrl', ['$scope','$ionicPlatform','$cordovaSms','ContactPicker', function ($scope, $ionicPlatform, $cordovaSms, ContactPicker) {
console.log('enetered in ctrl');
$scope.form={}
$scope.counter=contactCount;
/*
calling the contact picker service : ContactPicker which returns the merged contact details of the contacts picked
*/
$scope.doContactPicker=function() {
console.log(ContactPicker);
$scope.answer='answer';
$scope.answer =ContactPicker.pickedContact();
$scope.$watch('answer', function() {
document.getElementById("contactFetched").innerHTML =$scope.answer;
alert('sample alert displayed');
});
};
/*
function to add contact data to the array of items
gentrating new div items on button click
*/
$scope.users = [];
$scope.add = function () {
$scope.users.push({
firstName: "",
email: "",
mobile: ""
});
};
/*
function to send sms using cordova message plugin api
input : form.number and form.message
*/
$scope.sendSms = function(){
console.log($scope.form.number);
console.log($scope.form.message);
var options = {
replaceLineBreaks: false, // true to replace \n by a new line, false by default
android: {
intent: '' // send SMS with the native android SMS messaging
//intent: '' // send SMS without open any other app
}
};
$ionicPlatform.ready(function(){
$cordovaSms
.send($scope.form.number, $scope.form.message, options)
.then(function(result) {
console.log(result);
}, function(error) {
console.log(error);
})
})
}
}]);
最后是services.js文件
var finalContacts="";
var nameService=angular.module('NameService',[]);
nameService.service('getName',function() {
console.log("service created");
this.nameFetched=function getUserName(c) {
console.log("inside picked contact");
var name =c;
return name;
}
});
nameService.service('ContactPicker',function() {
console.log("service created");
this.pickedContact=function() {
console.log("inside picked contact");
//alert("inside");
navigator.contacts.pickContact(function(contact){
//alert("inside");
// console.log('The following contact has been selected:' + JSON.stringify(contact));
//alert(JSON.stringify(contact));
//Build a simple string to display the Contact - would be better in Handlebars
var s = "";
//s += "<h2>"+getName.nameFetched('yatin data')+"</h2>";
if(contact.emails && contact.emails.length) {
s+= "Email: "+contact.emails[0].value+"<br/>";
}
if(contact.phoneNumbers && contact.phoneNumbers.length) {
s+= "Phone: "+contact.phoneNumbers[0].value+"<br/>";
}
if(contact.photos && contact.photos.length) {
s+= "<p><img src='"+contact.photos[0].value+"'></p>";
}
finalContacts+=s;
//$("#selectedContact").html("hello world");
},function(err){
alert('Error: ' + err);
console.log('Error: ' + err);
});
return finalContacts;
}
});
控件在此函数调用时中断 navigator.contacts.pickContact(function(contact){
使用 ionic 服务，我在浏览器上测试了它，但由于所选的联系功能可以在设备本身上运行，因此我在浏览器中收到以下错误:-
TypeError: Cannot read property 'pickContact' of undefined
但是使用设备调试选项，我无法到达 navigator.contacts.pickContact(function(contact){ 内部，即不显示其中的警报。 请帮我解决这个问题。 谢谢
最佳答案
首先，cordova.js 的引用在哪里？即:
<script src="cordova.js"></script>
那么，你是否正确安装了 cordova-plugin-contacts ？
Cordova 插件仅在设备上可用，而不在浏览器中可用，因此您必须在设备上安装构建的应用程序，将其连接到计算机并通过 USB 进行调试(具体方式取决于特定平台 iOS/Android/...)。
关于javascript - 联系人插件 cordova 没有获取联系人也没有给出任何错误？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34721079/
