I have a combo that allows user to get the not, now i would like to populate another combo with the scaletype after selecting the note,

tried something simple to get going by showing value in paragraph but its not working.

if i select "C" then return scaletypes for C is the objective

<!DOCTYPE html>
<html>
<body>
    <input type="file" id="fileinput" />
 
<pre id="file"></pre>
    <p>Select The Tonic from the list.</p>

    <select id="mySelect" onchange="myFunction()">
        <option value="A">A</option>
        <option value="B">B</option>
        <option value="C">C</option>
        <option value="D">D</option>
        <option value="E">E</option>
        <option value="F">F</option>
        <option value="G">G</option>
        <option value="Ab">Ab</option>
        <option value="Bb">Bb</option>
        <option value="Db">Db</option>
        <option value="Eb">Eb</option>
        <option value="Gb">Gb</option>
    </select>

There are many ways to do this.

First way - as you have it using JQuery.
HTML
    <select id="mySelect">
        <option value="A">A</option>
        <option value="B">B</option>
        <option value="C">C</option>
        <option value="D">D</option>
        <option value="E">E</option>
        <option value="F">F</option>
        <option value="G">G</option>
        <option value="Ab">Ab</option>
        <option value="Bb">Bb</option>
        <option value="Db">Db</option>
        <option value="Eb">Eb</option>
        <option value="Gb">Gb</option>
    </select>
  <select id="scaletype">
  </select>

Open in new window

JQuery
<script src="http://code.jquery.com/jquery.js"></script>  
<script src="js\scales.js"></script>
<script>
$(function() {
  $('#mySelect').change(function() {
    var sel = $(this).val();
    $('#scaletype').empty();
    $.each(Scales, function(i,e) {
      if (e.Tonic == sel) {
        $('#scaletype').append(
          $('<option/>').html(e.ScaleType).val(e.ScaleType)
        );
      }
    });
  });
});
</script>

In the above code there are a few things to note
1. I have moved the data off into a separate JS file
2. I have included the JQuery library
Working sample here
In the next post I will show a different method using restructured data.
EDIT - Adding Scales.js
var Scales = [{ "Tonic": "C", "ScaleType": "Whole Tone" },
 { "Tonic": "C", "ScaleType": "Minor Blues" },
 { "Tonic": "C", "ScaleType": "Minor Pentatonic" },

Option 2 is based on restructuring the data - if this is not possible then it does not really matter as the data set is small, I am providing this for interest

The main difference between this version and the previous one is that we can index into the array based on the first selection - we then have access to all the options for that selection without having to iterate through the entire set of options.

this is why searching online doesnt help, that is really thorough I will practice each way. the small dataset is in sqlserver but I dont want to access it that way, all i did was convert it xml in sqlserver then i used a find and replace to create the text file.

this gets me over that hurdle.
how do i close off do i just pick the last one as best  as to me they are all best.

the path is relative to the parent file - so for that line to work you would need a subfolder off the folder that the main html file is in called js

In other words
<root>
   index.html
   <js>
       scales.js

Open in new window

You can play with the paths to suit you - it does not have to be structured like that - you could put the js file in the same folder as the main html file and then just do

<script src="scales.js"></script>
