How to Limit the Words Input In Quill.js?

You can limit the number of words input in Quill.js by setting up a custom validation function. This function can count the number of words in the editor and prevent the user from entering more words once the limit is reached. You can also display a message to let the user know that they have exceeded the word limit. To implement this, you would need to listen for the 'text-change' event in Quill.js and call your validation function to check the number of words. If the limit is exceeded, you can use Quill's methods to delete or prevent further input. This approach allows you to restrict the number of words input in Quill.js effectively.

What is the code snippet to limit word input in quill.js?

To limit word input in Quill.js, you can use the following code snippet:

 1
 2
 3
 4
 5

 8
 9
10
11

var quill = new Quill('#editor', {
  modules: {
    toolbar: '#toolbar'
  },
  theme: 'snow'
});

quill.on('text-change', function(delta, oldDelta, source) {
  var text = quill.getText();
  var words = text.split(/\s+/);
  if (words.length > 10) { // Change 10 to the desired word limit
    words.splice(10, words.length);
    quill.setText(words.join(' '));
  }
});

This code snippet creates a Quill editor instance and listens for text changes. It then calculates the number of words in the text and limits it to a specified number. In this example, the word limit is set to 10, but you can change it to any desired limit. If the limit is exceeded, the excess words are removed.

How to customize the word limit message in quill.js?

To customize the word limit message in Quill.js, you can use the Quill editor's built-in event listeners and methods to display a custom message when the word limit is reached. Here's a step-by-step guide on how to do this:

1. Set the word limit for the Quill editor by using the Quill editor's maxLength module. You can specify the maximum number of words allowed in the editor by adding the maxLength option when initializing the Quill editor:

1
2
3
4
5
6
7
8

var quill = new Quill('#editor', {
  modules: {
    maxLength: {
      maxLength: 100 // specify the maximum number of words allowed
    }
  },
  theme: 'snow'
});

1. Add an event listener to listen for changes in the editor's content and check if the word limit has been reached. You can use the editor's text-change event to monitor changes in the editor's content:

1
2
3
4
5
6
7
8
9

quill.on('text-change', function() {
  var text = quill.getText();
  var words = text.split(/\s+/).length - 1;

  if (words > 100) {
    // Display a custom message when the word limit is reached
    alert('Word limit exceeded. Please remove some words.');
  }
});

1. Customize the custom message to display a different message or style using HTML, CSS, or other JavaScript methods:

 1

10
11
12

quill.on('text-change', function() {
  var text = quill.getText();
  var words = text.split(/\s+/).length - 1;

  if (words > 100) {
    // Display a custom message when the word limit is reached
    document.getElementById('word-limit-message').innerText = 'Sorry, you have exceeded the word limit. Please remove some words.';
    document.getElementById('word-limit-message').style.color = 'red'; // Customize the style of the message
  } else {
    document.getElementById('word-limit-message').innerText = ''; // Clear the custom message if the word limit is not exceeded
  }
});

By following these steps, you can customize the word limit message in Quill.js to display a custom message when the word limit is reached and style it according to your preferences.

How do I set a dynamic word limit in quill.js?

To set a dynamic word limit in Quill.js, you can use the TextChange event to track the number of words in the editor and then enforce the desired word limit. Here's an example implementation:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15

var quill = new Quill('#editor', {
  theme: 'snow'
});

var wordLimit = 100;

quill.on('text-change', function(delta, oldDelta, source) {
  var text = quill.getText();
  var words = text.trim().split(/\s+/);

  if (words.length > wordLimit) {
    // Remove excess words
    var excessWords = words.slice(wordLimit).join(' ');
    var startIndex = text.indexOf(excessWords);
    quill.deleteText(startIndex, excessWords.length);
  }
});

In this code snippet, we first create a Quill instance and define the word limit (100 in this case). We then listen for the text-change event and calculate the number of words in the editor. If the number of words exceeds the word limit, we use the deleteText method to remove the excess words from the editor.

You can modify the wordLimit variable to set your desired word limit. This approach enforces the word limit dynamically as the user types in the editor.
