Kendo UI for jQuery
Captchas are a common spam-fighting element for web forms, but they can be tedious to create. The jQuery Captcha makes implementing it a set-and-forget task. This component requests the user to input information from a distorted image, representing letters and numbers. It also provides audio reproduction of the image as an additional option for stronger security.
The jQuery Captcha performs validation for you. Once the user types the required values, the component can check validation on the server (more secure than client-side validation) and display the result.
In order to be easily accessible and used by all users, the Captcha component’s distorted image can be read out loud using the NATO phonetic alphabet. An audio button is rendered next to the Captcha by default and if the user activates the audio, a slider will appear to let the user adjust the volume.
The jQuery Captcha supports any globalization or localization scenarios. You can also enable RTL mode to display the control’s text and UI elements from left to right.
Improve accessibility and productivity with keyboard-only navigation. This component supports keyboard navigation to help navigate and interact with items.
See the jQuery Captcha Keyboard Navigation demo.
The jQuery Captcha is compliant with Section 508 standards, is AA rated with WCAG 2.0 and follows WAI-ARIA standards.
