Question

我正在尝试学习PhoneGap并开始创建简单的演示。我刚刚编写了一个代码来显示页面上的警报。但它根本没有显示警报并显示Unable to open asset URL: file:///android_asset/www/cordova_plugins.json的错误。

我已经查看了与错误相关的SO的所有答案，并且尝试了但没有人帮助过我。

更新：

以下是我的错误：

这是我的html文件：

                        }

                        function init(){
                                document.addEventListener("deviceready", showMessageBox, true);     
                               navigator.notification.alert("Hello World of PhoneGap");

       <plugin name="NetworkStatus" value="org.apache.cordova.NetworkManager"/>
       <plugin name="Notification" value="org.apache.cordova.Notification"/>
</widget>

enter image description here

由于我在cordova_plugins.js文件夹中添加了asset/www/文件，上面对话框的错误消失了，但它已经停止再次向我显示警告对话框，并显示我已更新的不同错误我的错误日志。如果我删除该文件，它会显示警告消息以及错误对话框。

我只是不明白我哪里出错了。

请帮我解决这个问题。任何帮助将不胜感激。

谢谢你。

Answer 1

您添加了两个插件。你在cordova_plugins.js中声明了吗？

像这样的东西。

cordova.define('cordova/plugin_list', function(require, exports, module) {
    module.exports = [{
        "file": "plugins/org.apache.cordova.dialogs/www/notification.js",
        "id": "org.apache.cordova.dialogs.notification",
        "merges": ["navigator.notification"]
    }, {
        "file": "plugins/org.apache.cordova.network-information/www/network.js",
        "id": "org.apache.cordova.network-information.network",
        "clobbers": ["navigator.connection", "navigator.network.connection"]
    }];
    module.exports.metadata = // TOP OF METADATA 
    {
        "org.apache.cordova.device": "0.2.8",
        "org.apache.cordova.network-information": "0.2.7"
    }
});

请检查一下。 http://docs.phonegap.com/en/3.0.0/plugin_ref_spec.md.html

尝试这个

navigator.notification.alert('Your Alert Message', null, 'Alert', 'OK');

警报未显示在Phonegap中
