跳转到基于条件的不同开关案例，如goto(Jump to a different switch case based on conditon, like a goto)

我需要根据病情从一种病例转移到另一种病例。 例如，这是我的代码：

switch (req.method) { case 'GET': alert('GET METHOD'); break; case 'POST': alert('POST METHOD'); break; case 'PUT': alert('PUT METHOD'); break; default: res.end(); }

在上面的代码中，在POST情况下，我需要检查，例如， if(A === B) ，然后去像这样的PUT情况。 这个怎么做？

I need to move from one case to another case based on the condition. For example, this is my code:

switch (req.method) { case 'GET': alert('GET METHOD'); break; case 'POST': alert('POST METHOD'); break; case 'PUT': alert('PUT METHOD'); break; default: res.end(); }

In the above code, in the POST case I need to check, for example if(A === B), then go to the PUT case like that. How to do this?

进行条件递归

function checkMethod(method) { switch (method) { case 'GET': alert('GET METHOD'); break; case 'POST': alert('POST METHOD'); checkMethod('PUT'); // here stand the pros of a function break; case 'PUT': alert('PUT METHOD'); break; default: res.end(); } }

Make a conditional recursive

function checkMethod(method) { switch (method) { case 'GET': alert('GET METHOD'); break; case 'POST': alert('POST METHOD'); checkMethod('PUT'); // here stand the pros of a function break; case 'PUT': alert('PUT METHOD'); break; default: res.end(); } }
