I have created a <ul>
element and what I am trying to do is to highlight the list elements from a certain child and all the way up. However, because of the nested children, when I highlight a parent also all its children are highlighted (while I want to highlight only the text of the parents).
https://jsfiddle.net/zcfvuh6h/3/
In this example, I should get the nodes Four12, Four1 and Four highlighted.
Any suggestions? Thank you.
Okay, so after understanding what the actual problem you are trying to solve is, it took a bit of work, but I got a working solution.
A few things to note
1. All of your text in your <li>
need to be in a container of some sort, a <span>
is fine. You had some in spans and some not, so I put them all in spans for you.
2. This cannot be done with background-color
on the <li>
or <ul>
because it spans multiple lines if it has children. You have to use a css pseudo-element
in order to get the desired effect.
3. The demo I have posted also dynamically sets the background of the element and parents based on which element you click on. You must click on a list item in order for the backgrounds colors to show up.
4. Your d3 code that you included is all obsolete at this point. It can be done with 7 toal lines of jQuery.
5. Enjoy!
