如何在CordedWebApps中使用Cordova InAppBrowser?

我有一个网站,其中显示了2个与Cordova一起显示的移动应用程序,它们的运行效果非常好。但是我有一个问题:

当用户触发外部链接时,他退出了应用程序,没有任何机会回到应用程序... (关闭并重新打开)。 / p>

我已经根据inappbrowser安装了to this tutorial。听起来很简单,但不起作用...

控制台:

cordova plugin add cordova-plugin-inappbrowser

链接(应该触发InAppBrowser-不起作用):

 <a href="#" onclick="window.open('http://www.google.com', '_blank', 'location=yes', 'toolbar=yes'); return false;">www.google.com</a>

我刚刚记得,我的应用程序是通过名为Hosted Web App的技术来显示的。也许这是InAppBrowser无法正常工作的原因:我们已经在浏览器中了?!

我将剪裁下面的配置和js代码here's the tutorial of Microsoft who helped me on the App setting

目标:找到一个使用InAppBrowser的方法,因为我们网站上有很多外部链接。

有什么想法吗? 非常感谢 !

这是代码:

Index.js

var app = {
    // Application Constructor
    initialize: function() {
    this.bindEvents();
    },
    bindEvents: function() {
        document.addEventListener('deviceready', this.onDeviceReady, false);
    },
    onDeviceReady: function() {
        app.receivedEvent('deviceready');

        // Here, we redirect to the web site.
        var targetUrl = "https://www.website.test/";
        var bkpLink = document.getElementById("bkpLink");
        bkpLink.setAttribute("href", targetUrl);
        bkpLink.text = targetUrl;
        window.location.replace(targetUrl);
},
    // Note: This code is taken from the Cordova CLI template.
    receivedEvent: function(id) {
        var parentElement = document.getElementById(id);
        var listeningElement = parentElement.querySelector('.listening');
        var receivedElement = parentElement.querySelector('.received');

        listeningElement.setAttribute('style', 'display:none;');
        receivedElement.setAttribute('style', 'display:block;');

        console.log('Received Event: ' + id);
    }
};

app.initialize();

App.js

/*global app, $on */
(function () {
  'use strict';

  /**
   * Sets up a brand new Todo list.
   *
   * @param {string} name The name of your new to do list.
   */
  function Todo(name) {
    this.storage = new app.Store(name);
    this.model = new app.Model(this.storage);
    this.template = new app.Template();
    this.view = new app.View(this.template);
    this.controller = new app.Controller(this.model, this.view);
  }

  var todo = new Todo('todos-vanillajs');

  function setView() {
    todo.controller.setView(document.location.hash);
  }
  $on(window, 'load', setView);
  $on(window, 'hashchange', setView);

    var onSuccess = function(position) {
        var geotext = document.getElementById('geotext');
        geotext.textContent = 'Latitude: ' + position.coords.latitude + '\n' +
          'Longitude: ' + position.coords.longitude;
    };

    var onError = function onError(error) {
    alert('code: '    + error.code    + '\n' +
          'message: ' + error.message + '\n');
    }

    var button = document.getElementById('geo');
    button.addEventListener("click", function(){
                          navigator.geolocation.getCurrentPosition(onSuccess, onError);
                          });


    function myOnDeviceReady() {
        if (navigator.connection.type == Connection.NONE) {
            navigator.notification.alert('An internet connection is required to continue');
        } else {
            window.location="https://www.website.test/";
        }
    }
    document.addEventListener("deviceready", myOnDeviceReady, false);

})();

根据您的问题和后续情况,我假设您正在将yourwebsite.com加载到您的移动应用中,然后在yourwebsite.com上要打开外部链接,但将otherwebsite.com保留在您的应用中。如果我的理解正确,则可以通过将postMessage()发送回带有外部链接的移动应用程序,来在移动应用程序中加载yourwebsite.com并使用inAppBrowser打开外部链接。

首先,在移动应用上的<iframe>内加载到yourwebsite.com:

<iframe src="https://www.yourwebsite.com">

在yourwebsite.com上,单击外部链接时(在我的示例中,这是. external_url类的任何内容,您很可能必须使用querySelectorAll来代替多个链接),将其捕获JS并通过postMessage()将href值发送回移动应用:

document.querySelector('.external_url').addEventListener('click', function(event) {
  event.preventDefault(); // stops the user from loading this link
  var data = {'external_url': event.target.href};
  window.parent.postMessage(data, '*');
});

回到您的移动应用程序,您需要收听传入的postMesssage()。并触发inAppBrowser打开从yourwebsite.com返回的外部URL。

window.addEventListener('message', function(event) {
  if (event.data.external_url) {
    window.cordova.InAppBrowser.open(event.data.external_url, '_blank', 'location=no');
  }
}, true);

我尚未测试此代码,但是应该通过一些更改使您指向正确的方向。
