  • 0

I my previous question I asked how to implement the chat feature using client side technology especially using jquery mobile. I had also put up the question in the jquery mobile forums too but I was disappointed.
Finally I was able to set-up a chat feature on my local machine by referring this blog

I am running jsJac client side chat but now I am implement the same thing using jquery mobile frame work I googled and try to figure out how it can be done, but could not find any examples as such. If any suggestions and ideas on how to do and get the things done, kindly help to achieve this.

Thank you.

    The people at pub nub have kindly incorporated my code in into the samples on their
    web site if the code below dosen’t work
    goto http://www.pubnub.com/blog/easy-mobile-chat-html5-jquery-mobile

    This html will work straight out of the box in the browser (you don’t need a server – useful for mobile web apps)

    eg. Create a file with the below html on your c: drive c:\temp\chat.html . Then point your chrome browser to
    file:///C:/temp/chat.html. Alternatively upload the html to a host. Then point the iphone or android or PC broswer to the url and let your jaw drop. mobile – to mobile to pc chat! This runs purely in the js client u don’t need your own server

    Note, this is a open demo chat channel, goto pub nub for more details http://www.pubnub.com

    Enjoy
