JSService 和 Weex 实例在 JS Runtime 中并行运行。Weex 实例的生命周期可调用 JSService 生命周期。目前提供创建、刷新、销毁生命周期。
重要提醒: JSService 使用不当会导致内存增高或全局污染!
[WXSDKEngine registerService:@"SERVICE_NAME" withScript: @"SERVICE_JS_CODE" withOptions: @{}]; // or [WXSDKEngine registerService:@"SERVICE_NAME" serviceScriptUrl: @"SERVICE_JS_URL" withOptions: @{}];
HashMap<String, String> 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)
params of
options
Could have { create, refresh, destroy } lifecycle methods. In create method it should return an object of what variables or classes would be injected into theWeex
instance.
<script src="SERVICE_JS_CODE_URL"></script>
service.register(SERVICE_NAME /* same string with native */, { /** * JSService lifecycle. JSService `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 }) } } } } }, /** * JSService lifecycle. JSService `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){ }, /** * JSService lifecycle. JSService `destroy` will before then each instance lifecycle `destroy`. You can deleted variable here. If you doesn't detete variable define in JSService. 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) { } })
Use JSService
<script> var _InstanceService = new InstanceService(weex) var _NormalService = new service.NormalService(weex) module.exports = { created: fucntion() { // called modal module to toast something _InstanceService.toast('Instance JSService') _NormalService.toast('Normal JSService') } } </script>
