The slider text is not getting updated when onclick() is triggered

My project involves a map with a slider that adjusts the display of points as you slide from year 1 to year 10.

Some of these points are filtered based on certain parameters linked to 4 buttons.

The issue I'm facing is that when sliding the slider and then clicking on one of the buttons, the text showing the number of points on the map does not update. The update only occurs after moving the slider again, not when clicking the button.

I need to ensure that once a button is clicked, both the map and the text reflecting the point count update simultaneously.

Despite trying various solutions, none seem to resolve this issue. I'm unsure where to focus my troubleshooting efforts.

No error messages have been reported thus far.

Answer №1

An unconventional but effective solution would be to simply substitute the filterData() function call within the buttonClick function with the logic used in the slider callback --

document.getElementById("slidertext").innerHTML = "Achieved Goals:  " + filterData() + "   ";
. It's surprising that this approach wasn't considered earlier. It may be beneficial to refactor this into a separate method to eliminate redundancy.
