A jQuery & SVG based triangle picker that enables the user to select a point within the triangle and returns an object containing Top Middle, Bottom Left, and Bottom Right positions after selections.

How to use it:

1. Include jQuery library and the jQuery Picker.js plugin's file on the html page.

<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" 
        integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" 
        crossorigin="anonymous">
</script>
<script src="picker.js"></script>
<link rel="stylesheet" href="style.css">

2. Create a container element for the triangle picker.

<div id="picker"></div>

3. Initialize the triangle picker.

$('#picker').trianglePicker();

4. Get the Top Middle, Bottom Left, and Bottom Right positions with the onChange callback.

// trianglePicker(el, options, onChange)
$('#picker').trianglePicker(null, function(name, values) {
  console.log(values)
});

5. Default plugin options.
