Extract Keywords From Text Using jQuery - Keywords Extractor

Many developers and bloggers need the ability to take some text and extract keywords from it. For example to find keywords for SEO you can use this action.

This is a simple jQuery based Keywords Extractor that extracts keywords from any given text string by checking if words meet min/max lengths, not numbers, not duplicates, and are not in an exclude array.

How to use it:

1. Code the HTML for the keyword extracter. We're using Bootstrap framework in this example to style the text field and keyword list.

<form action="#">
  <div class="row mb-4">
    <div class="col-md-6 col-sm-12 border border-dark p-5">
      <h5 for="comment" class="fw-bold">Your Text</h5>
      <textarea class="form-control keywords-title" rows="5" id="comment" name="text"></textarea>
    </div>
    <div class="col-md-6 col-sm-12 border border-dark p-5">
      <h5 for="comment" class="fw-bold">Results</h5>
      <table class="table">
        <thead>
          <tr>
          <th>Tag</th>
          <th>Value</th>
          <th>Copy</th>
          </tr>
        </thead>
      </table>
      <div class="fixed-content">
      <table class="table">
        <tbody id="keywords-table-data">
          <tr id="default-data">
            <td>--</td>
            <td>--</td>
            <td>--</td> 
          </tr>
        </tbody>
      </table>
      </div>
    </div>
  </div>
</form>

2. Load the Keywords Extractor's JavaScript after jQuery.

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

3. Set the min/max length of words which will be considered as keywords. Default: 4/20.

var min_lenght = 4;
var max_lenght = 20;

4. Override & extend the exclude array.

var exclude_array = ['a','about','all','also','and','as','at','be','because','but','by','can','come','could','day','do','even','find','first','for','from','get','give','go','have','he','her','here','him','his','how','I','if','in','into','it','its','just','know','like','look','make','man','many','me','more','my','new','no','not','now','of','on','one','only','or','other','our','out','people','say','see','she','so','some','take','tell','than','that','the','their','them','then','there','these','they','thing','think','this','those','time','to','two','up','use','very','want','way','we','well','what','when','which','who','will','with','would','year','you','your','has','was','why'];

5. Enable the 'Copy To Clipboard' feature.

<script src="https://cdnjs.cloudflare.com/ajax/libs/clipboard.js/2.0.8/clipboard.min.js"></script>

var clipboard = new ClipboardJS('.copy-btn');
