Maximum Length in EJ2 JavaScript TextArea Control

25 Mar 20243 minutes to read

You can enforce a maximum length limit for the text input in the TextArea using the maxLength property. This property allows to define the maximum number of characters that users can input into the TextArea.

  • By setting the maxLength property, you can control the length of text input, preventing users from exceeding a specified character limit.
// Initialize the TextArea control.
var textareaObj = new ej.inputs.TextArea({
    placeholder: 'Enter your comments',
    maxLength: 20
});
// Render initialized TextArea.
textareaObj.appendTo('#default');

When the user reaches the specified limit, the TextArea prevents further input, ensuring compliance with the defined character limit. This feature helps maintain data integrity and provides users with clear feedback on the allowed input length.
