JQuery Scroll Limit to Span Text

July 9, 2022

Firstly please excuse my knowledge of JQuery im a total noob and struggline to get this code to work.
I did try a search but could not find a solution for my issue.

Ok so I have a little scroll bar which allows the user to select a tempo from 40 to 300 bpm
these are the limits I have set for the slider.

Under the slider is a text input box so people can just enter the bpm manually example: 121
If the number entered is lower or highr then the limites meantioned above, I need to set the Span text to the lower or higher limit (example 40 lower limit and 300 max limit)

I also need 2 outputs updating at the same time: one is the text input field and the other is a span

here is the code I have

$('#BPMRange')
  .on('input', function() {
    var value = $(this).val();
    $('#Test').text(value);
  })


$('#BPM')
  .keyup(function() {
    var value = $(this).val();
    $('#Test').text(value);
  })
  .keyup();


$('#BPM').on('change blur', function() {
  if ($(this).val().trim().length === 0) {
    $(this).val($default_BPM);
    var value = $(this).val();
  }

  if ($(this).val() < 40) {
    $('#Test').text('40');
  } else if ($(this).val() > 300) {
    $('#Test').text('300');
  }
})

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="BPM_Slide_Container">
  <input type="range" min="40" max="300" value="300" class="BPM_Slider" id="BPMRange">
  <br>
  <input name="BPM" type="text" id="BPM" value="300" class="TempoField">
</div>



<span id="Test"></span>

Thank you for any advice you can share – I do appreciate it

>Solution :

Just change the others’ text() or val() on change event.

var range = $('#BPMRange')
var input = $('#BPM')
var test = $("#Test");

range
  .on('input', function() {
    var value = $(this).val();
    test.text(value);
    input.val(value)
  })


input.on('change', function() {
  var value = $(this).val();
  value = Math.min(300, value);
  value = Math.max(40, value);
  range.val(value);
  test.text(value);
  input.val(value)
})

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="BPM_Slide_Container">
  <input type="range" min="40" max="300" value="300" class="BPM_Slider" id="BPMRange">
  <br>
  <input name="BPM" type="text" id="BPM" value="300" class="TempoField">
</div>

<span id="Test"></span>
