Ways to display values below the slider?

Ways to display values below the slider?

I'm currently working on a data visualization project and am facing an issue with adding values to a slider. The slider itself is functioning correctly, but I can't seem to display any values below it on the webpage. My goal is to show dates like 2021-12-15 beneath the slider. How can I achieve this? Below is the code I've been working on so far. Thank you in advance!

<div class="slidecontainer">
    <input type="range" min="1" max="12" value="12" class="slider" id="mySlider">
</div>

<script>
    var slider = document.getElementById("mySlider");
    var output = document.getElementById("demo");
    output.innerHTML = slider.value; // Display the default slider value

    // Update the current slider value (each time you drag the slider handle)
    slider.oninput = function() {
        output.innerHTML = this.value;
    }
</script>

function slider_Update(binNumber) {
    new_date = formatTime(new Date("2008-"+binNumber+"-01"));
      let checked_group = ".";
      let count = 1;
      // For each checkbox:
    d3.selectAll(".checkbox").each(function(d){
        const cb = d3.select(this);
        const grp = cb.property("value");
        
      if(cb.property("checked")){
        if(count===1){
          checked_group += grp;
          count++;
          
        }else{
          checked_group += ",."+grp;
          
        }
      }
    })
    
    update_Worldmap(checked_group);
    update_BarPlot();
  }

  
  d3.select("#mySlider").on("change", function(d){
    selectedValue = this.value
      slider_Update(selectedValue)
    
  })

Your HTML code is missing an element with the id demo. To rectify this issue, you can follow these steps:

var slider = document.getElementById("mySlider");
var output = document.getElementById("demo");
output.innerHTML = slider.value; // Display the default slider value

// Update the current slider value (each time you drag the slider handle)
slider.oninput = function() {
  output.innerHTML = this.value;
};

<div class="slidecontainer">
  <input type="range" min="1" max="12" value="12" class="slider" id="mySlider" />
  <div id="demo"></div>
</div>

Why don't we generate a new element and display the updated date in that element?

<div class="slidecontainer">
    <input type="range" min="1" max="12" value="12" class="slider" id="mySlider">
    <div id="slideDate"></div>
</div>

<script>
    var slider = document.getElementById("mySlider");
    var output = document.getElementById("demo");
    output.innerHTML = slider.value; // Display the default slider value

    // Update the current slider value (each time you drag the slider handle)
    slider.oninput = function() {
        output.innerHTML = this.value;
    }


function slider_Update(binNumber) {
    var new_date = formatTime(new Date("2008-"+binNumber+"-01"));
      let checked_group = ".";
      let count = 1;
      // For each checkbox:
    d3.selectAll(".checkbox").each(function(d){
        const cb = d3.select(this);
        const grp = cb.property("value");
        //console.log(cb.property("checked")+" "+cb.property("value"));
      // If the box is check, add to checked_group, else hide
      if(cb.property("checked")){
        if(count===1){
          checked_group += grp;
          count++;
          //console.log(checked_group+"  count: "+count);
        }else{
          checked_group += ",."+grp;
          //count++;
          //console.log(checked_group+"  count: "+count);
        }
      }
    })
    //change opacity for created group
    update_Worldmap(checked_group);
    update_BarPlot();
    $("#mySlider").html(new_date)
  }

  //Slider source

To extract the slider value, simply include a div element like so:

var slider = document.getElementById("mySlider");
var output = document.getElementById("slidertext");
output.innerHTML = slider.value; // Display the default slider value

console.log(output);

    // Update the current slider value (each time you drag the slider handle)
    slider.oninput = function() {
        output.innerHTML = this.value;
    }

function slider_Update(binNumber) {
    new_date = formatTime(new Date("2008-"+binNumber+"-01"));
      let checked_group = ".";
      let count = 1;
      // For each checkbox:
    d3.selectAll(".checkbox").each(function(d){
        const cb = d3.select(this);
        const grp = cb.property("value");
        //console.log(cb.property("checked")+" "+cb.property("value"));
      // If the box is check, add to checked_group, else hide
      if(cb.property("checked")){
        if(count===1){
          checked_group += grp;
          count++;
          //console.log(checked_group+"  count: "+count);
        }else{
          checked_group += ",."+grp;
          //count++;
          //console.log(checked_group+"  count: "+count);
        }
      }
    })
    //change opacity for created group
    update_Worldmap(checked_group);
    update_BarPlot();
  }

  //Slider source
  //https://www.d3-graph-gallery.com/graph/density_slider.html
  // Listen to the slider
  d3.select("#mySlider").on("change", function(d){
    selectedValue = this.value
      slider_Update(selectedValue)
    //console.log("from mySldier select: "+selectedValue)
  })

<div class="slidecontainer">
    <input type="range" min="1" max="12" value="12" class="slider" id="mySlider">
</div>
<div id = "slidertext"></div>

Please provide more details on the functionality required for the date aspect of the slider. Does it need to modify the entire date or just the months? Appreciate your input.
