Need javascript for my survey page

[JK28]

Hi,

I have a survey page, and i want people who has submit the survey CAN NOT access my survey page again. So, a person can only submit the form only once. Perhaps with a pop up window note saying "Ups Sorry,it seems that you have submit the survey, you are not allowed to do it again"

Any javascript for this? Thanks

JK

You can apply a IP based restriction for your survey page. But it is better if you consider a server-side tool like PHP rather than a client-side tool like JavaScript for the purpose.

thanks codeexploiter, im thinking perhaps a simple javascript that can recognize a cookies. btw do you have a sample/demo page or a tutorial for this IP based restriction?
