Check If Input Or Textarea Value Matches A String - jQuery Field Compare String

Field Compare String is a jQuery plugin that checks if a value you typed in an input field or textarea element matches a text string you specify.

Also provides success/error feedbacks if you typed a valid/invalid value.

How to use it:

1. Include the jFieldCompareString plugin's script after jQuery.

<script src="https://code.jquery.com/jquery-1.12.4.min.js" 
        integrity="sha384-nvAa0+6Qg9clwYCGGPpDQLVpLNn0fRaROjHqs13t4Ggj3Ez50XnGQqc/r8MhnRDZ" 
        crossorigin="anonymous">
</script>
<script src="js/jquery.jFieldCompareString.min.js"></script>

2. Specify the text string to which your text field should be compared:

<div class="jfcs-wrapper">

  <!-- Text string container -->
  <div class="jfcs-reference">
    <p>
      Text String Here
    </p>
  </div>

  <!-- Form field -->
  <div class="jfcs-field">
    <input type="text" id="example">
  </div>

</div>

3. Attch the plugin to the text field. That's it.

$('#example').jFieldCompareString();

4. Customize the feedback messages.

$('#example').jFieldCompareString({
  msg_notok: 'Your transcript has an error, please correct.',
  msg_incomplete: 'Your transcript is incomplete, please correct.',
  msg_ok: 'Your transcript is correct.'
});

5. Decide whether to disable the copy and paste events on the text field. Default: false.

$('#example').jFieldCompareString({
  field_protection: true
});

6. To enable the plugin on multiple text fields within the document:

<div class="demo-2">
  <p>
    Text String Here
  </p>
</div>

$('#example').jFieldCompareString({
  compare_to: '#demo-2'
});
