// The xajaxResponse class is used to created responses to be sent back to your
|
||
|
|
// webpage. A response contains one or more command messages for updating your page.
|
||
|
|
// Currently xajax supports 17 kinds of command messages, including some common ones such as:
|
||
|
|
// * Assign - sets the specified attribute of an element in your page
|
||
|
|
// * Append - appends data to the end of the specified attribute of an element in your page
|
||
|
|
// * Prepend - prepends data to the beginning of the specified attribute of an element in your page
|
||
|
|
// * Replace - searches for and replaces data in the specified attribute of an element in your page
|
||
|
|
// * Script - runs the supplied JavaScript code
|
||
|
|
// * Alert - shows an alert box with the supplied message text
|
||
|
|
//
|
||
|
|
// *Note: elements are identified by their HTML id, so if you don't see your browser HTML display changing from the request, make sure you're using the right id names in your response.
