What is the best way to separate text entered by the user into its individual characters?

Question

What is the best way to separate text entered by the user into its individual characters?

Is there a way to allow users to drag each character they type on the screen individually?

I'm trying to figure out how to access and manipulate each character the user enters.

In the example below, I can manipulate each character of the word "placemark." How can I do this for user-inputted text?

HTML

<!doctype html>
<html>
  <head>

Answer №1

It seems like the solution you provided should work. Simply enter some text in the box and click the button to test it

Here is a breakdown of the process:

Collect the user's input and separate it into individual characters
Combine the characters in a way that encapsulates each one in a specific element (such as a span or div)
Insert these elements into the document object model (DOM)
Apply the draggable functionality to the added elements

function initializeDraggable($elements) {
  $elements.draggable();
}
initializeDraggable($('.character'));

$(function(){
    $('#make-word').click(function() {
      var $this = $(this);
      var letters = $('#my-word').val().split('');
      letters = '<div class="character">'+letters.join('</div><div class="character">')+'</div>';
      initializeDraggable($('#word-container').html(letters).find('.character'));
    });
});

.character {
  width: 10px;
  height: 15px;
  font-size: 50px;
  display: inline;
  cursor: drag;
}

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js">
</script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.9/jquery-ui.min.js"></script>

<div id="word-container">
  <div class="character">P</div>
  <div class="character">l</div>
  <div class="character">a</div>
  <div class="character">c</div>
  <div class="character">e</div>
  <div class="character">m</div>
  <div class="character">a</div>
  <div class="character">r</div>
  <div class="character">k</div>
</div>
<br>

<form action="demo_form">
  Word:
  <input type="text" id="my-word" name="fname">
  <br>
  <button type="button" id="make-word">Make word</button>
</form>

If you want to treat each character separately, you'll need to get a bit creative. One way to achieve this is by using the .keypress() trigger in jQuery.

Another option is to utilize the <button> element to create draggable elements, such as <div class="character">.

Alternatively, you can see an example below that demonstrates how to turn the last character you typed into a draggable element:

$('input[type="text"]').keypress(function() {
    var lastCharacter = $(this).val().slice(-1);
    $('body').append('<div class="draggable">'+lastCharacter +'</div>');
    //make element draggable
    $('.draggable').draggable();
});
