Question

我是科尔多瓦的新手。我已经完成了Cordova 3.5.0的安装过程，你好世界计划对我来说很好。但是，当我尝试使用一些Cordova API之类的Alert时，它会在logcat中给出以下错误：

07-18 03:42:07.060: D/CordovaActivity(1183): onMessage(onPageStarted,file:///android_asset/www/index1.html)
07-18 03:42:08.170: D/CordovaWebViewClient(1183): onPageFinished(file:///android_asset/www/index1.html)
07-18 03:42:08.170: D/CordovaActivity(1183): onMessage(onPageFinished,file:///android_asset/www/index1.html)
07-18 03:42:08.410: D/CordovaActivity(1183): onMessage(spinner,stop)
07-18 03:42:10.180: D/CordovaActivity(1183): onMessage(spinner,stop)
07-18 03:42:12.740: D/CordovaLog(1183): file:///android_asset/www/index1.html: Line 28 : Uncaught TypeError: Cannot call method 'alert' of undefined

这是我的HelloWorld.java

package com.example.hello;

import org.apache.cordova.CordovaActivity;

import android.os.Bundle;

public class HelloWorld extends CordovaActivity 
{
    @SuppressWarnings("deprecation")
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        //super.init();
        // Set by <content src="index.html" /> in config.xml
        //super.loadUrl(Config.getStartUrl());
        //super.loadUrl("file:///android_asset/www/index.html");



        super.setIntegerProperty("splashscreen", R.drawable.splash);
        super.loadUrl("file:///android_asset/www/index1.html", 5000);
    }
}

这是我的index1.html：

<!DOCTYPE html>
<html>
  <head>
    <title>Notification Example</title>

    <script type="text/javascript" charset="utf-8" src="cordova.js"></script>

    <script type="text/javascript" charset="utf-8">

    // Wait for device API libraries to load
    //
    document.addEventListener("deviceready", onDeviceReady, false);

    // device APIs are available
    //
    function onDeviceReady() {
        // Empty
    }

    // alert dialog dismissed
        function alertDismissed() {
            // do something
        }

    // Show a custom alertDismissed
    //
    function showAlert() {
        navigator.notification.alert(
            'You are the winner!',  // message
            alertDismissed,         // callback
            'Game Over',            // title
            'Done'                  // buttonName
        );
    }

    </script>
  </head>
  <body>
    <p><a href="#" onclick="showAlert(); return false;">Show Alert</a></p>
  </body>
</html>

您需要先添加对话框插件。您可以使用以下命令添加它。

cordova plugin add org.apache.cordova.dialogs
