Hi

I have a CGI page where i want to refresh only a <div> . Actually I need to show information from database which constantly gets updated. And I am not sure how to refresh only a specific part of page and query the database each time and show the updated content.

Can someone please let me know how to do it?

    There's a way to do this without JavaScript: turn the <div> into a <iframe>. The iframe loads another CGI, which outputs just the updated data.

    It's probably better to go the JavaScript route, though.

      Thanks that sounds interesting. Will look into it.

        While it can work (sort of, in certain ways), please note well this part of the post: It's probably better to go the JavaScript route, though.

        Iframes come with their own problems and Ajax is not that hard.

    You can do this easily with the jquery load function. This loads the url and puts the content into the div. Full details and examples can be found in the documentation. 

    $('#my_div').load('/my/url/to/load');
