F.A.Q
CONSTRUCT simplejax(string uri, string callback [, object errorHandler])
Arguments :
- uri - URI associated to page for data retrieval
- callback - Callback function for successful data retrieval
- errorHandler - Callback function for error handler
Description:
Simplejax library for clean page requests. Supports both POST and GET.Example:
function fooCallBack(response)
{/* Handle response data */}
function barCallBack(error)
{/* Handle error */}
simplejax = new simplejax('foo.txt', fooCallback, barCallback);
PRIVATE object ^ bool construct()
Description:
Object creation method, privately accessed, handles both ActiveX and Netscape's proprietary objectPUBLIC void set(enum option, mixed value, [,string argument])
Arguments :
- option - set option
- value - Value for option
- argument - POST argument string
Description:
Set options, values are saved in reserved buffer variables and are accessed when invoke method is invoked.Available options:
string URL - Assign a new url
object CALLBACK - Assign a new callback function
mixed ARGUMENT - Provide the value to an argument in the callback
enum(GET,POST) METHOD - second parameter is the post arguments
bool XML - Return content type as XML
bool JSON - Parse as JSON and return object
Example:
// Changing the set URL
simplejax.set('URL', 'bar.txt');
// Changing the callback
function myCallBack(response)
{
alert(response.toUpperCase());
}
simplejax.set('CALLBACK', myCallBack);
// Set first parameter (after the response)
simplejax.set('ARGUMENT', 'foo');
// Change the method to post
simplejax.set('METHOD', 'POST', 'foo=bar&bar=bork');
// POST can now accept an array of post values [ new in Simplejax 1.4 ]
simplejax.set('METHOD', 'POST', new Array('foo=bar', 'bar=bork'));
// Set return type to XML
simplejax.set('XML', true);
// Set return type to JSON evaluated object
simplejax.set('JSON', true);
// Set a post parameter on the fly [ new in Simplejax 1.4 ]
simplejax.set('POSTPARAM', 'fieldname', 'value');
PUBLIC void ^bool invoke( [,mixed options])
Arguments :
- options - arguments to provide to callback
Description:
Invoke object creation and establish callback.Example:
<a href="javascript:void(0);" onclick="simplejax.invoke()">Invoke</a>
//Provide the callback arguments with values
