Question

我安装了模块，但我无法确定我的worker.js文件应该在项目中的哪个位置。这是一个Alloy项目，我尝试将文件放在几个不同的地方。

我把我的工作人员放到了这个测试位置：

worker.addEventListener('message', function(event){
   worker.postMessage('complete');
});

我一直收到这个错误：

Answer 1

这是SDK 2.1+的问题，没有计划修复。 https://github.com/appcelerator-modules/ti.worker/issues/5

Answer 2

将它放在app/lib中，app/lib中的所有文件都将放在生成的Resources/目录的基础中，这样你就可以在任何控制器中访问这样的worker.js用于实例化worker：

var worker = require('ti.worker');

// create a worker thread instance
var task = worker.createWorker('worker.js');
task.postMessage({
   msg:'Hello'
});

此应该将消息发布到您的worker.js文件中。虽然没有测试过，祝你好运！

在哪里为ti.worker Titanium模块放置工人文件？
