在科尔多瓦应用中发射事件 [英] Firing events in Cordova applications

问题描述

我正在尝试从浏览器手动触发事件（backbutton，pause，resume等）（用于调试）。我以下列方式进行：

I am trying to trigger events (backbutton, pause, resume etc) in cordova manually from the browser (for debugging). I am doing it in the following way:

$(window).trigger('backbutton');

< backbutton'，handlerCode）;

backbutton事件被触发，但是当我们使用cordova文档中的语法注册它时

the backbutton event gets triggered, however when we register it using the syntax in the cordova documentation

document.addEventListener("backbutton", onBackKeyDown, false);

不触发事件处理程序。我注意到，当我使用 $（window）.trigger（'backbutton'）时，代码没有打到cordova.js文件。从浏览器调用cordova应用程序的正确方法是什么？

the event handler is not triggered. I noticed this when I used $(window).trigger('backbutton'), the code did not hit the cordova.js file. What would be the right way to invoke events in cordova application from the browser?

推荐答案

可以从浏览器中触发事件。为了触发事件，需要fireWindowEvent或fireDocumentEvent。

It is possible to fire the events from browser. In order to fire the events, it is required to either fireWindowEvent or fireDocumentEvent.

要启动暂停，恢复，在线，离线，后退按钮，menubutton，搜索按钮，startcallbutton， endcallbutton，volumeupbutton，volivedownbutton，使用fireDocumentEvent。例如，触发暂停事件： -

To fire the pause, resume, online, offline, backbutton, menubutton, searchbutton, startcallbutton, endcallbutton, volumeupbutton, volumedownbutton, use the fireDocumentEvent. eg, firing 'pause' event:-

cordova.fireDocumentEvent('pause',{});

为了触发与电池相关的事件，请使用fireWindowEvent。例如，发射电子政治事件： -

In order to fire events related to battery, use fireWindowEvent. eg, firing 'batterycritical' event:-

cordova.fireWindowEvent('batterycritical', {"level":"20","isPlugged":true});
