Flyport Wi-Fi and Ethernet Programmer's guide framework 2.3 (rev 1.0) www.openpicus.com

This function processes every POST request from the pages.

*****************************************************************************/

HTTP_IO_RESULT HTTPExecutePost(void)

{

return HTTP_IO_DONE;

}

#endif

void HTTPPrint_string_serial(void)

{

TCPPutString(sktHTTP,(BYTE*) string_serial);

}

#endif

As can be seen, there are two main operations in this file, and they are the declaration of

extern char string_serial[];

and the function

void HTTPPrint_string_serial(void)

that executes a TCP write to communicate the value of string_serial at the client

QUESTION: Is there a way to update values without the need of refreshing the whole page?

The answer lies in the using of AJAX.

AJAX in Action

AJAX is used to automatically update values in webpages without the need of continual refreshes of

the overall HTML page.

Using AJAX the request for data from the Flyport will be prompted directly by the webpage, and the

browser does not have to refresh the entire page. With AJAX, the data are truly dynamic, with

automatic refreshes of only the data that need to be updated.

Here is an example of a serial to webpage string using AJAX scripts. In this example, files in addition

to index.htm are used. The folder structure is:

• index.htm

• status.xml

• leds.cgi

• mchp.js

• header.inc

• footer.inc

• style.css

• images/openpicus_logo_blog.png

• images/arrow.gif

• images/bar.gif

• images/baractive.gif
