Captcha Generator using JavaScript

By Sai Baba Kotha

Generation of random Captcha using JavaScript and its functions. Captcha is basically a mixture of random combinations of letters and numbers in a very random way.

Generation of Captcha is performed by using a combination of numbers and letters both uppercase and lowercase. The generated Captcha is the random combination of letters and numbers generated in a random way.

A refresh button is specified to regenerate the captcha. We can regenerate it any number of times we want. A Submit button is specified to submit the captcha and the submit button also checks the entered captcha and the generated captcha. This function allows it to be an interactive website.
