Native.js虽然强大和开放,但很多web开发者因为不熟悉原生API而难以独立完成。

这篇帖子的目的就是汇总各种写好的NJS代码,方便web开发者。

众人拾柴火焰高,有能力的开发者多多提交NJS代码,大家都会给你点赞的,

Android平台

在桌面创建和删除App快捷方式

见Hello H5+里Native.js部分演示及源码。
或在这里搜索“快捷方式”,http://ask.dcloud.net.cn/docs/ ... le/88调用Android本地分享

数据读取 
打开网络设置 
调用系统控件播放视频 
 
调用讯飞的文字转语音功能(TTS)

例说明如何使用Native.js进行BroadcastReceiver广播http://ask.dcloud.net.cn/question/7661常驻Android通知栏,不用个推实现本地消息推送(Local Notification)
 
开启个推推送功能
var pushManager = plus.android.importClass("com.igexin.sdk.PushManager");
var context = plus.android.runtimeMainActivity();
function enable() {
    pushManager.getInstance().turnOnPush(context);
}
function disable() {
    pushManager.getInstance().turnOffPush(context);
}

var bundle = NSBundle.mainBundle();
console.log(bundle.bundleIdentifier());
plus.ios.deleteObject(bundle);
获取设备名

var scrollView = webview.plusGetAttribute("scrollView");
scrollView.plusSetAttribute("decelerationRate:",0.99);
打开ios的Wifi设置页面 
http://ask.dcloud.net.cn/article/188ios获取系统的时区id
var NSTimeZone = plus.ios.importClass("NSTimeZone");
var sys = NSTimeZone.systemTimeZone();
console.log(sys.plusGetAttribute("name"));
状态栏显示网络请求雪花
var UIApplication = plus.ios.import("UIApplication");
var sharedApplication = UIApplication.sharedApplication();
sharedApplication.setNetworkActivityIndicatorVisible(true);
plus.ios.deleteObject(sharedApplication);
获取GPS授权状态
var CLLocationManager = plus.ios.import("CLLocationManager");
var authorizationStatus = CLLocationManager.authorizationStatus();
switch(authorizationStatus) {
      case 0:
      /// User has not yet made a choice with regards to this application
      break;
      case 1:
      // This application is not authorized to use location services.  Due
    // to active restrictions on location services, the user cannot change
    // this status, and may not have personally denied authorization
      break;
      case 2:
        // User has explicitly denied authorization for this application, or
    // location services are disabled in Settings.
      break;
      case 3:
        // User has granted authorization to use their location at any time,
    // including monitoring for regions, visits, or significant location changes.
      break;
      case 4:
       // User has granted authorization to use their location only when your app
    // is visible to them (it will be made visible to them if you continue to
    // receive location updates while in the background).  Authorization to use
    // launch APIs has not been granted.
      break;
      case 5:
     // This value is deprecated, but was equivalent to the new -Always value.
      break;
      defalut:
      break;
}
获取手机存储空间
var BundleClass = plus.ios.importClass("NSBundle");
var BundleObj = BundleClass.mainBundle();
var filenamagerobj = plus.ios.newObject("NSFileManager");
var FileAttr = plus.ios.invoke(filenamagerobj,"attributesOfFileSystemForPath:error:",BundleObj.bundlePath(),null);
// NSFileSystemFreeSize 参数获取剩余空间
// NSFileSystemSize  获取手机总存储空间
var freeSpace = plus.ios.invoke(FileAttr,"objectForKey:","NSFileSystemFreeSize");
var numberFormatterObj = plus.ios.newObject("NSNumberFormatter");
var FreeSpaceStr = plus.ios.invoke(numberFormatterObj,"stringFromNumber:",freeSpace);
var freeSpace = FreeSpaceStr / 1024/1024/1024;
看完这些例子,是不是觉得JS特别强大?
赶快拿去用起来吧!
