你好,科尔多瓦
您应该能够使用和PhoneGap.exec()
方法完成此操作
在c#中创建一个继承自BaseCommand的类(还必须使用此特定命名空间):
从Javascript调用此方法:
var args = {"message":"whatever"};
PhoneGap.exec(null, null, "MyCommand", "DoThis", args);
您可以将Notify方法与ScriptNotify事件处理程序结合使用,如以下博文所述:-
不要将Java与Javascript混淆:)嗨,约翰逊,谢谢你,我尝试了上面的代码,但它产生了类似“phonegap未定义”的错误,我应该做些什么更改吗?我尝试这段代码时出错了,你能解释一下上面的代码吗?我出错了?提前谢谢你使用了确切的名称空间吗?耶,即使出现错误。我是否需要进行任何外部更改?谢谢。那么在调用该方法之前,您可能还没有定义args。这是基本的东西。我已经更新了我的答案。
var args = {"message":"whatever"};
PhoneGap.exec(null, null, "MyCommand", "DoThis", args);
