Fire An Event On Caret Position Change - jQuery Position Event

This is a jQuery solution to detect the current position (position, line, column) of the mouse pointer in a text field and fire an event each time the caret position changes while typing.

Supports both textarea and input field elements.

Install & Download:

# NPM
$ npm install jquery-position-event --save

How to use it:

1. Load the main JavaScript after loading the latest jQuery JavaScript library.

<script src="/path/to/cdn/jquery.min.js"></script>
<script src="/path/to/index.js"></script>

2. Attach the caret change event handler to a text field.

<input id="example" />
<!-- OR -->
<textarea id="example"></textarea>

var textField = $('example').on('position', function(e) {
    // do something
});

3. Trigger & remove the caret change handler.

// trigger
textField.trigger('position');

// remove
textField.off('position');

4. This will return an event object containing 3 properties as follows:

{

  // position index
  "position": 10,

  // column index
  "column": 10,

  // line index
  "line": 0
  
}
