JS service 和 Weex 实例在 JS runtime 中并行运行。Weex 实例的生命周期可调用 JS service 生命周期。目前提供创建、刷新、销毁生命周期。

重要提醒: JS Service 非常强大但也很危险，请小心使用！

注册 JS Service

iOS

[WeexSDKEngine registerService:@"SERVICE_NAME" withScript: @"SERVICE_JS_CODE" withOptions: @{}];复制代码

Android

HashMap
    
      options = new HashMap<>()options.put("k1", "v1")String SERVICE_NAME = "SERVICE_NAME"String SERVICE_JS_CODE = "SERVICE_JS_CODE"boolean result = WXSDKEngine.registerService(SERVICE_NAME, SERVICE_JS_CODE, options)复制代码

编写一个 JS service

// options: native inject options// options.serviceName is native options nameservice.register(options.serviceName, {  /**    * JS Service lifecycle. JS Service `create` will before then each instance lifecycle `create`. The return param `instance` is Weex protected param. This object will return to instance global. Other params will in the `services` at instance.    *    * @param  {String} id  instance id    * @param  {Object} env device environment    * @return {Object}    */  create: function(id, env, config) {    return {      instance: {        InstanceService: function(weex) {          var modal = weex.requireModule('modal')          return {            toast: function(title) {              modal.toast({ message: title })            }          }        }      },      NormalService: function(weex) {        var modal = weex.requireModule('modal')        return {          toast: function(title) {            modal.toast({ message: title })          }        }      }    }  },  /**    * JS Service lifecycle. JS Service `refresh` will before then each instance lifecycle `refresh`. If you want to reset variable or something on instance refresh.    *    * @param  {String} id  instance id    * @param  {Object} env device environment    */  refresh: function(id, env, config){  },  /**    * JS Service lifecycle. JS Service `destroy` will before then each instance lifecycle `destroy`. You can deleted variable here. If you doesn't detete variable define in JS Service. The variable will always in the js runtime. It's would be memory leak risk.    *    * @param  {String} id  instance id    * @param  {Object} env device environment    * @return {Object}    */  destroy: function(id, env) {  }})复制代码
