How do I customize/format slider scale options?

https://www.qualtrics.com/community/discussion/comment/10359#Comment_10359Hi Mslreen, is there a way to add this to the popup numbers on the moving slider itself?

Hi qualfun ,
You can achieve the same(to prepend "$" in show value") using the below code by adding below code into Qualtrics JS API:

Qualtrics.SurveyEngine.addOnload(function()
{
/*Place your JavaScript here to run when the page loads*/

});

Qualtrics.SurveyEngine.addOnReady(function()
{
/*Place your JavaScript here to run when the page is fully displayed*/
// Select the node that will be observed for mutations
const targetNode = document.getElementsByClassName("sliderToolTipBox")[0];
let observer = new MutationObserver(function() {
targetNode.innerHTML ="$"+ Math.abs(targetNode.innerHTML);
observer.disconnect(); // turn observer off;
observer.observe(targetNode, {
 attributes: true,
 childList: true, // observe direct children
 subtree: true, // and lower descendants too
 characterDataOldValue: true // pass old data to callback
});// turn back on

});

// observe everything except attributes
observer.observe(targetNode, {
 attributes: true,
 childList: true, // observe direct children
 subtree: true, // and lower descendants too
 characterDataOldValue: true // pass old data to callback

});

});

Qualtrics.SurveyEngine.addOnUnload(function()
{
/*Place your JavaScript here to run when the page is unloaded*/

});
