CSS animation triggers only first time

Time：10-09

I am making a witcher themed page as a side project and have come across a problem. I have made an alchemy page and have all ingredients listed, with all elements that can be extracted beside them. I have made a function that triggers animation with the following logic: Clicking an ingredient will trigger the animations for the according elements that can be extracted from said ingredient. For example: Fool's parsley can produce Rubedo and Vitriol, upon clicking fools parsley, rubedo shines red and vitriol blue. My problem is that once an animation is triggered once, it wont trigger again if needed for another ingredient. Example: Fools parsley makes rubedo and vitriol shine, Cadaverine makes rubedo and aether shine. If i click fools parsley, then Cadaverine, when cadaverine is clicked, only aether will shine because rubedo was already triggered once. This also makes clicking the same ingredient twice pointless, as the second time none of the elements will shine.

Here is the code:

Seems like a very basic JS problem but I'm stuck and cant seem to find a workaround. Thank you in advance!

CodePudding user response：

Admittedly this is not supposed to be a code restructuring discussion or problem but there is a way to solve this using the animationend event and with the associated callback remove the animation assigned with the click on the Herbal extract.

You'll note that the bulk of this is done with Javascript rather than masses of inline styles and function calls -it makes it easier (imo) to expand upon and maintain but others may be the judge of that.

The important piece that you could take from this would be the event listener assigned to each Herbal Extract li element - clearly identified below:

CodePudding user response：

On the first line of your for statement, try this:

this[elementList[i]].style.animation = "";

You need to remove the animation, and then add it again in order for it to start again.

CodePudding user response：

Try to set this.

animation-iteration-count: 1;
