Can't get dynamic reloading to work...

michael.griffith

Following the example for reloading the dataset dynamically, I have a button that a user clicks to display the DataTable -- which pulls data from the server based on what the user clicked on. The server side code is never being invoked, so I am not sure what I am doing wrong. Using DataTables 1.6.2 with Struts 2.
[code]
partsData=$('#parts_table').dataTable( {
"bProcessing" : true,
"bServerSide": true,
"sAjaxSource": "./partlist-data.do",
"fnServerData": function ( sSource, aoData, fnCallback ) {
/* Add some extra data to the sender */
aoData.push( { "name": "engineId", "value": "1" } );
$.getJSON( sSource, aoData, function (json) {
/* Do whatever additional processing you want on the callback, then tell DataTables */
fnCallback(json)
});
}
});
[/code]

In the test above, the struts action is not invoked each time I display/hide the table. I have hard coded the value I want to pass but it would be pulled from a hidden form field value using $("#engineId").val();

I tried calling the redraw function before the div that the table is in is shown, but I get an oSettings = null error when doing so...
[code]
partsData.fnClearTable(0);
partsData.fnDraw();
[/code]

This produces oSettings is null

Concept seems simple... what could I be doing wrong?

Any/all replies are appreciated.

Bump? Can no one tell me what is wrong with the example I posted above?

I don't really see anything wrong with the code you've posted (although you don't need to call fnClearTable - fnDraw basically done that anyway with server-side processing). Are you sure the code is being invoked? Any JS errors in the console?

Thanks for your reply Allan. No JS errors are reported in FireBug. The call to fnClearTable was a desperate attempt to make it work, so I'll remove it. The server side code is never being invoked -- which is what my question/problem pertains to...

So if you put in an alert() just before the call to $.getJSON - does that occur?

If not - then an alert() just before the $().dataTable() call?
