bProcessing API?

scullytr

Hello,

I was wondering if there was some sort of api for the "Processing..." message. Perhaps a way to pass custom messages to that div and fire it off for user-feedback.

I can, of course, hack something together myself, but I wanted to know if there was anything more clean and built-in. No sense in reinventing things. :-)

Thank you!

-Tim.

You can use the sProcessing language option to change what is shown, but there is no current API to change the message on-the-fly (a plug-in could be created if you need it). There is a plug-in to control the show / hide of the indicator: http://datatables.net/plug-ins/api#fnProcessingIndicator .

Thank you Allan. That helps a lot.

From what I read in other posts, there isn't a way to change the value of sProcessing after dataTable init, so what I did (after using the above method) is directly changed the innerHTML of the div, displayed the custom message, hid the message, and changed it back to "Processing...", like so:

Plugin:
[code]
$.fn.dataTableExt.oApi.fnProcessingIndicator = function ( oSettings, onoff )
{
if( typeof(onoff) == 'undefined' )
{
onoff=true;
}
this.oApi._fnProcessingDisplay( oSettings, onoff );
};
[/code]

Custom message method:
[code]
function notify(msg){
var msgSpot = $('.dataTables_processing');

// Default value if none is specified
msg = typeof(msg) == 'undefined' ? 'Processing...' : msg;

// Replace the text in the nofication area with the specified text, and make it visible
$(msgSpot).html(msg);
oTable.fnProcessingIndicator();

// After 2 seconds, hide the notice, and put it back the way we found it
setTimeout(function(){
oTable.fnProcessingIndicator(false);
$(msgSpot).html('Processing...');
}, 2000);
}
[/code]
