update value in the ui via node programming

[elemich]

hi, i modified an existing node and in the "required" field i inserted a value (the one that you can change with the arrows in the ui). how can i update in the ui this value after having changed it for some reason in the code?

See this

thank you for your response.
i alredy seen this but i don't understand how it works,cause i have already a lot of return values.
in my case i have a
required "DirectoryIndex": ("INT", {"default": -1, "min": -1, "max": 0xffffffffffffffff})
and RETURN_TYPES = ("INT","INT","STRING","STRING","STRING","INT","INT","STRING","STRING","STRING","STRING")
(none of return types has noting to do with DirectoryIndex)
how to adapt your example to my case?

also can you point me to some sites where there is a comfy programming manual with a function reference?

i only found docs.comfy.org but it is very poor in content.

i have a lot of question on this comfyui and it would be unkind to bother you with them

{
   "ui": {"DirectoryIndex": <a value that updates the widget>}, 
   "result": <a tuple containing output values>
}

i wrote:

def function(self,DirectoryIndex)
DirectoryIndex+=1
return {
"ui":{"DirectoryIndex": DirectoryIndex}, (but i also tried with a literal, for example 20)
"result":(return types 1,return type 2, etc...)
}

and it gives me an error:

ui = {k: [y for x in uis for y in x[k]] for k in uis[0].keys()}
TypeError: 'int' object is not subscriptable

ok, solution is putting [] around the parameter, "ui":{"DirectoryIndex": [DirectoryIndex]}.
this make error not appear anymore,but the value of the widget remains the same.

[ltdrdata]

Oh, I provided the wrong guide.
In this case, the node is ultimately handled in JavaScript.
Since there are limitations to the data that can be passed through the "ui" in the return statement, I recommend using my approach.

i created a js\common.js and putted inside the event handler like that in your repo, after i added in the init.py the js stuff so now it looks like this:

from .WAS_Node_Suite import NODE_CLASS_MAPPINGS

all = ['NODE_CLASS_MAPPINGS']

WEB_DIRECTORY = "./js"
all = ["NODE_CLASS_MAPPINGS", "NODE_DISPLAY_NAME_MAPPINGS", "WEB_DIRECTORY"]

i putted a console.log("@mic nodeFeedbackHandler") but nothing appear in the console

how to register the event handler? (comfyui lacks a programming manual)

[ltdrdata]

This is the event handler registering code.

I have to correct this and apologize a lot,the code works, i expecting the log in the cmd console,but it were in the browser stuff... I'm not used to javascript

for half a day can't understand while "DirectoryIndex"!="DiretoryIndex"
