When I execute method `to`, method `from` fails, how do I fix it?

[dxcqcv 1 Likes (Newbie)]

I modified the official `splitText` example so that the text is not displayed by default, when the `show` button is clicked the text is displayed, when the `disappear` button is clicked the text disappears, then when I click the `show` button again the text is not displayed, I want to click the `disappear` button and then click the `show` button to display the text again, how should I modify it? Thanks

That's happening because your 'disappear' tween ends with an opacity of 0. Then you click the 'show' button which is a from tween, but it tweens from 0 to its current value which is also 0 so it appears nothing is happening. Probably best to use a fromtTo() tween if this is the way you want to wire this project.

Happy tweening.

thx for your response,

 

and I'm very confused  "because your 'disappear' tween ends with an opacity of 0",  because I already set the dom  opacity is 1 before `from` method, right? like 

 .set('#quote', {opacity: 1})

so I think `show` button will be set opacity of 1 every time before it does tween 

 

and I also try to change to `fromTo` method, but it's not work, I don't know why, 

the demo is

Hi,

 

There are a few issues with your GSAP config. You're setting the from values in the to object:

  tl
    .fromTo(chars, {
      opacity: 0,
    }, {
      duration: 0.8,
      opacity: 1,
      scale: 0,
      y: 80,
      rotationX: 180,
      transformOrigin: "0% 50% -50",
      ease: "back",
      stagger: 0.01
    }
    );
  };

You're basically telling GSAP animate the elements from opacity 0, to:

• opacity: 1,
• scale: 0
• y: 80
• rotationX: 180

So basically that scale 0 will mean that the elements will not be visible. Also your quote element still has an opacity of 0.

 

This seems to work:

document.getElementById("show").onclick = function () {
  gsap.set("#quote", { opacity: 1 });
  tl.fromTo(
    chars,
    {
      opacity: 0,
      scale: 0,
      y: 80,
      rotationX: 180,
    },
    {
      duration: 0.8,
      opacity: 1,
      scale: 1,
      y: 0,
      rotationX: 0,
      transformOrigin: "0% 50% -50",
      ease: "back",
      stagger: 0.01
    }
  );
};

Hopefully this helps.

Happy Tweening!

Yes - you set the #quote div to opacity:1, but you're animating the opacity of the characters which are all in their own div.  Think of the original #quote div as the parent and all the line,word and char divs as children created by SplitText. Hopefully that makes sense.

 

I think @Rodrigo's snippet above should get you all fixed up. Happy tweening.

Thanks to  @Rodrigo and @PointC for rescuing me from the mud puddle.
