Adding Measurement Units to the Values in RoundSlider: A Step-by-Step Guide

I'm working on a roundslider widget and I want to display units with the values. If the value is between 0 and 999, it should show "Hz" next to it. For values between 1000 and 999999, "KHz" should be displayed, and so on.

Below is the original slider configuration:

$("#slider").roundSlider({
  sliderType: "min-range",
  radius: 150,
  handleSize: "+12",
  mouseScrollAction: true,
  min: 0,
  max: 100000000,
  value: 0, // default value on start

  change: function(event) {
   $.getJSON('/set_Frequency/' + event.value);
  }

});

Here is my attempt that is not functioning correctly:

$("#slider").roundSlider({
  sliderType: "min-range",
  radius: 150,
  handleSize: "+12",
  mouseScrollAction: true,
  min: 0,
  max: 100000000,
  value: 0, // default value at start

  change: function(event) {
    var value = event.value, content;
    if (value <= 999) content = "Hz";
    else if (value <= 999999) content = "KHz";
    else if (value >= 1000000) content = "MHz";
    else content = "GHz";
    $.getJSON('/set_Frequency/' + event.value + content);
  }

});

Any assistance would be appreciated. Thank you.

Answer №1

To customize the format, you have the option to utilize the tooltipFormat event. I presume you are interested in selecting a value ranging from Hz to GHz.

I have made adjustments to the demonstration to align with your specific requirements. Now, you can choose a value between 1 kHz and 100 MHz.

If you provide your actual usage scenario, I can offer more precise recommendations to meet your needs.
