Question

我正在使用cordova-plugin-contacts插件创建一个IONIC ANDROID APP来读取联系人并将其显示在离子列表中。

        <button class="button" ng-click="showcontact()">Add New Contact</button>
      </ion-header-bar>
      <ion-content>
      <h3 id="Data">Welcome to my app created by Ionic Cortova !! Yeh !!! Hello</h3>

        <ion-list >
            <ion-item ng-repeat="item in CListItems">
            {{item.displayName}}
            </ion-item>
        </ion-list>

      </ion-content>

    </ion-pane>
    <script>
    </script>
  </body>
</html>

app.js

// 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'
angular.module('starter', ['ionic','starter.controllers'])

.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();
    }
  });
})

controllers.js

angular.module('starter.controllers', [])
    .controller('CListControl', function ($scope) {

        $scope.CListItems=[{displayName: 'Mohit'}];
        document.getElementById("Data").innerHTML="Undone";

        //funtion to add items to the existing list
        $scope.showcontact = function() {
            console.log("before event");
            document.getElementById("Data").innerHTML="Done";
        document.addEventListener("deviceready", init, false);

        function init() {
            console.log("init");
            var options      = new ContactFindOptions();
        options.multiple= true;
        options.hasPhoneNumber = true;
        var fields       = [navigator.contacts.fieldType.displayName,navigator.contacts.fieldType.phoneNumbers];
        navigator.contacts.find(fields, gotContacts, errorHandler, options);
        console.log("init end");
        }


        //Error Alerting
        function errorHandler(e) {
        alert("errorHandler: "+e);
        }

        //Script to remove all the contacts without phonenumber.

        function gotContacts(c) {

        var i=0;
        len=c.length;
        while (i<len)
        {
            if (c[i].phoneNumbers==null)
            {
                c.splice(i,1);
                if (i!=0)   {i-=1;}
                len-=1;
            }
            else
            {
                $scope.CListItems.push(c[i]);
            }
            i+=1;

        }
        alert("Found:"+$scope.CListItems.length+" Contacts");

        }

        }
});

我的输出： -

应用程序启动正常，点击添加新联系人按钮，一段时间后我收到一条警告，显示我没有联系人。但离子列表中只有1个项目正在显示，即＆＃39; Mohit＆＃39; 。

但是当我再次点击添加新联系人按钮时，所有联系人都会填充在离子列表中。

我的问题： -

正如我解释的那样，我认为应用程序正在点击一下。任何想法都会造成这种情况。

我是离子框架和javascript的新手，所以如果它是一个简单的错误，请指出我。

谢谢。

Answer 1

答案非常简单，在我更改了mutate(moving.avg = rollapply(data = val, FUN = mean, width = 16, by = 16, align = "right", fill = NA))所观察到的变量值之后，我只需要使用$scope.$apply()。在这种情况下更新<ion-list>

之后

用联系人填充离子列表
