[enhancement]: allow to specify an effect attribute prefix

[monolith]

Hi, I will keep this short.
This is a simple feature, but I think it would be essential to prevent conflict with each user's code.

data-speed & data-lag might already be used in the DOM for other things than scrollsmoother; which might break some integrations.

 

What I'm suggesting is a new option for effects, EX:

let smoother = ScrollSmoother.create({
  wrapper: '#wrapper',
  content: '#content',
  smooth: 2,
  effects: true,
  prefix: 'my-prefix' // -> [data-my-prefix-(speed/lag)]
})

Passing a string to a prefix option would allow for more specific attributes to be used to trigger effects (without the need to play around with string or array scopes).

 

The above would output these:

• data-my-prefix-speed
• data-my-prefix-lag

It's a very reasonable request but I wonder if it's really necessary given the fact that you can just as easily do it with JavaScript: 

let smoother = ScrollSmoother.create({
  wrapper: '#wrapper',
  content: '#content',
  smooth: 2
})
smoother.effects("[data-my-prefix-speed], [data-my-prefix-lag]", {
  speed: el => el.getAttribute("data-my-prefix-speed") || 1,
  lag: el => el.getAttribute("data-my-prefix-lag") || 0
});

Did you know that?

Yeah that works!

But I do think that a "prefix" option would be very useful for a lot of people.

 

In any case, I think that this use case should be added to the docs. (either as the prefix options, or your snippet above)

Yeah, we'll likely add an effectsPrefix feature in the next release to accommodate this and ensure that the values are recorded in those spots properly too. 👍
