Modules - Shaofa/AliOS-Things-Certification-Manual GitHub Wiki
BoneEngine@lite 支持模块操作
- module.exports
- exports
模块内容的获取有两种途径
-
从外部注册函数中获取
JSE中提供API函数bone_engine_loadmodule_register，注册一个回调函数func，当JSE语法分析到require时，若JSE缓存中没有该模块时，会调用该func通过模块名来获取该模块的JS内容 - JS API模块注入 在JS app中Modules.addCached(module_name, code)注入
var myModule = require('myModule');
var myModuleInstance = new myModule();
print(myModuleInstance.hello());
print(myModuleInstance.goodbye());
var link = require('linkModule').Link;
print(link.start());
print(require('linkModule').mac);向JSE添加模块，以后调用require相关模块名时，会使用该模块内容
- module_name 模块名称
- code 模块JS代码
Modules.addCached("a","module.exports.foo=1;");
var ta = require("a").foo;
count += ta;
print('ta=' + ta);
Modules.addCached("b","module.exports = {foo:1};");
var tb = require("b").foo;
count += tb;
print('tb=' + tb);
Modules.addCached("c","module.exports = 1;");
var tc = require("c");
count += tc;
print('tc=' + tc);
Modules.addCached("d","exports.foo = 1;");
var td = require("d").foo;
count += td;
print('td=' + td);
Modules.addCached("e","exports.foo = function(){ return 1;};");
var te = require("e").foo();
count += te;
print('te=' + td);
var myModule = "function myModule() {" +
" this.hello = function() {" +
" return 'hello!'; " +
" }; " +
" this.goodbye = function() {" +
" return 'goodbye!';" +
" }; " +
"}; " +
"module.exports = myModule; " ;
//print('myModule=' + myModule);
Modules.addCached("myModule", myModule);
myModule = require('myModule');
var myModuleInstance = new myModule();
print(myModuleInstance.hello());
print(myModuleInstance.goodbye());
var linkModule = " " +
"var mac = 'abc'; " +
"function Link() { " +
" this.uuid = '1234';" +
"};" +
"var mLink = new Link();" +
"mLink.start = function(){" +
" return this.uuid + ' start';" +
"};" +
"module.exports.Link = mLink;" +
"module.exports.mac = mac;";
Modules.addCached("linkModule", linkModule);
linkModule = undefined;
link = require('linkModule').Link;
print(link.start());
print(require('linkModule').mac);�
