如何升级javascript以利用phonegap 2.3自定义插件?
我构建了一个名为tcpipcomplugin的定制插件,它使用Phonegap/Cordova 1.6.1。一切都很好,回调/插件结果也很好。但是我需要升级到Cordova 2.3。原因是我们现在正在Win8和iOS/Android上启动dev 除此之外,我还有以下javascript代码如何升级javascript以利用phonegap 2.3自定义插件?,java,javascript,android,cordova,Java,Javascript,Android,Cordova,我构建了一个名为tcpipcomplugin的定制插件,它使用Phonegap/Cordova 1.6.1。一切都很好,回调/插件结果也很好。但是我需要升级到Cordova 2.3。原因是我们现在正在Win8和iOS/Android上启动dev 除此之外,我还有以下javascript代码 var TCPComm = function() { }; TCPComm.prototype.Open = function(Cmd,successCallback, failureCallback) {
var TCPComm = function() {
};
TCPComm.prototype.Open = function(Cmd,successCallback, failureCallback) {
return PhoneGap.exec( successCallback, //Success callback from the plugin
failureCallback, //Error callback from the plugin
'TCPIPCommPlugin', //Tell PhoneGap to run "DirectoryListingPlugin" Plugin
'Open', //Tell plugin, which action we want to perform
[Cmd]); //Passing list of args to the plugin
};
这段代码将继续对插件进行大约10-12个不同的函数调用,然后以
PhoneGap.addConstructor(function() {
PhoneGap.addPlugin("TCPComm", new TCPComm());
});
在javascript本身中,实际的函数调用如下所示
window.plugins.TCPComm.Open(g_IpAddr, OpenOK,OpenFail);
此外,下面是JAVA插件的外观
@Override
public PluginResult execute(String action, JSONArray data, String callbackId) {
PluginResult result = null;
try {
Actions currentAction = Actions.valueOf(action.toUpperCase());
JSONObject Resp = new JSONObject();
String RespStr;
switch(currentAction){
case OPEN:
{
//do work
}catch (JSONException jsonEx) {
System.out.println(jsonEx.toString());
result = new PluginResult(Status.JSON_EXCEPTION);
}
return result;}
这对Cordova 1.6.1非常有效。然而,Cordova 2.x.x的情况并非如此。现在说了这么多,做了这么多,我仔细阅读了web,试图找到一种转换JAVA的方法。我得出了以下结论
公共布尔执行(字符串操作、JSONArray数据、CallbackContext CallbackContext){
这似乎与更新后的代码相匹配。我没有找到一种方法来更新JAVASCRIPT调用,使这个插件与更新后的CORDOVA一起工作
如有任何方向正确的帮助/建议,将不胜感激
我使用了以下文档,但没有成功。
更新
感谢Simon的回复。在此期间,我用以下内容替换了我的javascript。我需要将其恢复到之前的状态吗
cordova.define("cordova/plugin/TCPIPCommPlugin", function(require, exports, module){
var exec = require('cordova/exec');
var TCPComm = function() {};
// var TCPCommError = function(code, message) {
// this.code = code || null;
// this.message = message || '';
// };
TCPComm.prototype.Open = function(success,fail) {
return cordova.exec( successCallback, //Success callback from the plugin
failureCallback, //Error callback from the plugin
'TCPIPCommPlugin', //Tell PhoneGap to run "DirectoryListingPlugin" Plugin
'Open', //Tell plugin, which action we want to perform
[Cmd]);
};
var TCPIPCommPlugin = new TCPComm();
module.exports = TCPIPCommPlugin;
});
更新#2-修复了一些错误
我回到了旧的javascript并将其全部替换,所以现在看起来是这样的
var TCPComm = function() {};
TCPComm.prototype.Open = function(Cmd, successCallback,failureCallback) {
return cordova.exec( successCallback, //Success callback from the plugin
failureCallback, //Error callback from the plugin
'TCPIPCommPlugin', //Tell PhoneGap to run "DirectoryListingPlugin" Plugin
'Open', //Tell plugin, which action we want to perform
[Cmd]);
};
我还将构造函数替换为
if(!window.plugins) {
window.plugins = {};
}
if (!window.plugins.TCPComm) {
window.plugins.TCPComm = new TCPComm();
}
现在,当我在Chrome(UI调试)中运行它时,我可以看到插件内置了函数中所有正确的函数
Java很好,我忘了在论坛代码中包含返回值。哎呀
现在我像往常一样尝试调用函数,得到一个对象#在第一次JAVASCRIPT调用Close/Open时没有方法'exec'
window.plugins.TCPComm.Close("", Dummy, Dummy);
window.plugins.TCPComm.Open(g_IpAddr, OpenOK,OpenFail);
我在执行时在Java中设置了断点,让我知道插件何时成功调用Java,但仍然没有成功
还有其他想法吗?再次感谢您的见解。用以下代码替换PhoneGap.exec:
var TCPComm = function() {
};
TCPComm.prototype.Open = function(Cmd,successCallback, failureCallback) {
return cordova.exec( successCallback, //Success callback from the plugin
failureCallback, //Error callback from the plugin
'TCPIPCommPlugin', //Tell PhoneGap to run "DirectoryListingPlugin" Plugin
'Open', //Tell plugin, which action we want to perform
[Cmd]); //Passing list of args to the plugin
};
不推荐使用add constructor方法,请执行以下操作:
if(!window.plugins) {
window.plugins = {};
}
if (!window.plugins.videoPlayer) {
window.plugins.TCPComm = new TCPComm();
}
对于Java代码,您已经完成了大部分工作,但需要返回结果:
public boolean execute(String action, JSONArray data, CallbackContext callbackContext) {
PluginResult result = null;
try {
Actions currentAction = Actions.valueOf(action.toUpperCase());
JSONObject Resp = new JSONObject();
String RespStr;
switch(currentAction){
case OPEN:
//do work
this.callbackContext.sendPluginResult(
new PluginResult(PluginResult.Status.OK, results));
} catch (JSONException jsonEx) {
System.out.println(jsonEx.toString());
result = new PluginResult(Status.JSON_EXCEPTION);
}
return true;
}
那会让你升级的
public boolean execute(String action, JSONArray data, CallbackContext callbackContext) {
PluginResult result = null;
try {
Actions currentAction = Actions.valueOf(action.toUpperCase());
JSONObject Resp = new JSONObject();
String RespStr;
switch(currentAction){
case OPEN:
//do work
this.callbackContext.sendPluginResult(
new PluginResult(PluginResult.Status.OK, results));
} catch (JSONException jsonEx) {
System.out.println(jsonEx.toString());
result = new PluginResult(Status.JSON_EXCEPTION);
}
return true;
}
