QuerySelector in Lua?

Help and Feedback Scripting Support
#1

Hello everyone, just a quick question:

For those who know javascript, you might use .querySelector or .querySelectorAll; so is there a way to implement that in Roblox Lua. For who doesn’t what the query selector does - it gets the object’s name regardless of what their parent is in. For example: if parent1 has a child named child and parent2 has a child named child, by using querySelector, you can get te child of both parents without writing childOne = parent1.child and childTwo = parent2.child.

could you not just recursively :GetChildren() and filter by the name?

#3

Yeah, you can traverse the DOM tree recursively with

workspace:FindFirstChild("name", true)

The second argument makes it recursive throughout the entire hierarchy just like the querySelector.

@MrNicNac, are you saying that workspace:FindFirstChild("name", true) will search through all of the parents and find the children with that name?

#5

It will only return the first child found with the specified name.

#6

It will only look through all the descendants in Workspace. If you really wanted to you could do it from game to look everywhere.

wow, I never thought of that, thanks for the replies, I’ll keep this post going to see what other people can think of.

Yes, this is actually possible. I have successfully created a way to do the following in Lua:

local S = require('path/to/QuerySelector.lua')
S('model.model .frame#someID .textbutton')

I will be open-sourcing this soon as part of a bigger module.
