Can I use 2 different functions on the same route? Node.js

Question

I have 2 different methods that I want to be called when a specific form is filled. I know that I can't have a form with 2 actions so I am just wondering can I call 2 different methods on the same route in Node.js?

I need something like this

router.post('/webmark/addcollection', webmarks.addCollection);
router.post('/webmark/addcollection', webmarks.uploadPicture);

so basically when the button in the form is pressed, the action would redirect to the specific route and the 2 methods would be called.

Answer 1

No, if do it that way, then you will be overwriting the first.

A better approach to that is like below:

router.post('/webmark/addcollection', webmarks.addCollection, webmarks.uploadPicture);

And make sure you make the call to next middleware function here uploadPicture from addCollection handler by adding next() in addCollection middleware on the successful operation.

exports.addCollection = function(req, res, next){
  // You logic goes here
  // On success operation call next middleware

  next();
}

exports.uploadPicture = function(req, res){
  // You logic for uploadPicture
}

Answer 2

您的第一个函数接收3个输入(request, response, next) ，在此函数的结尾，调用next() 。

Answer 3

您只需将uploadPicture放在uploadPicture内， addCollection根据需要运行。
