Hi,
Can any body please help me getting my problem solved. I am making a sign up form, and i want to show "id not available" or "available", while user looses focus from a text box , without submitting the form. same as it happen in twitter while signing up.
Can any one please let me know how is it possible using JavaScript or Ajax or dojo?
Many thanks in advance :-)
Yes this is possible.
You will need a server side script to take the name the user wants, queries your database and outputs either yes or no.
You will need to use JavaScript (BTW, Ajax is JavaScript) to send a request to the server side script with the users name and get the response.
Take a look on Google, there are many tutorials and examples already available.
