Rows and lines defining

Question

I'm trying to highlight the rows and lines of each number when it's pressed. But some of the numbers highlight the wrong lines/rows. How can I fix it?

UPDATE: fixed it by searching by the index of the html element instead of searching by the numbers (due to repeating numbers/values).

Answer 1

You can store the element index as a user defined data on the tr dom element. Retrive it to access the array getting line and row that way.

Answer 2

One last issue would be picking the row or line element as the blue is changed to red. You may or may not want this behavor.

Answer 3

Part of your issue is you start with line on 27 & finish with row on 29 and reverse it for 31 & 33. Both usages in the pair should be the same. The rest of your issue is duplicate table values. Your search for the value will find the wrong one.
