如何在表单提交中实现线程

Question

大家好，我的前端有一个“ HTML”表单，后端有一个“龙卷风”表单。我的情况是，当用户单击“提交”按钮时，将在后端调用一个函数，这需要很长时间才能完成，所以我我打算保留一个进度条，以显示功能执行是否完成，并使用户能够提交另一种形式，该形式也与线程BY使用相同的功能，这意味着必须启动第二种形式，但处于等待状态。我这样做请建议我...谢谢

Before HTML5 you would not use threads but do this asychronically using callbacks. To implement this simply perform ajax requests, the callbacks can run in "parallel".

In order to get real parallel behavior you neef to use web workers wgich is not supported in all browsers since it is a relatively new HTML5 featute.
