Assistance with fnPageChange...

applaps

Hello,

What I am trying to do is have the datatable point the user to page one on each new search (i.e. each time the user clicks submit):

I tried to attach the fnPageChange to the onlick event, but cannot get it to work:

jsp:
[code]onclick="setDatalistPageOne()"[/code]


js:

[code]function setDatalistPageOne() {
var dataTable = $(#dataList).dataTable();
dataTable.fnPageChange('first', false);[/code]


My datatable gets initialised in the "$(document).ready(function() {" event. Eg:

[code]
$(document).ready(function() {
var dataTableInit = $("#dataListSearchSubject").dataTable( {
"bAutoWidth": true,
"bProcessing": true,
"bServerSide": true,
"bStateSave": true,
etc. etc etc. ,
"fnServerData": function ( sSource, aoData, fnCallback ) {
*some code in here*
}
});
} );
[/code]

Should i be calling fnChangePage in a similar way to the "fnServerData" - should it be outside the initialisation but still in the document.ready or should it be in an onclick like I have, but I am doing it wrong? I am a beginner to DataTables and this is some existing (working) code I have to maintain...

NOTE: I do need bStateSave to be true; so setting that to false won't solve my issue..

Thanks heaps

Ok, so I tried just adding the function in the onload and that doesnt work...

"dataTableInit.fnPageChange('first',false);"

behaviour is as follows:

1. Search for a people with name 'BOB'
2. returns several pages of people containing Bob in their name
3. Go to page 2 of results
4. Search for a specific Bob (should only return one result)
5. Page is set as 1, however a note is displayed saying no search results found (which is incorrect cause I know this person exists)
6. If I then just click search again, the search is performed and the correct record is displayed on page 1

not sure why, ill keep investigating and hope someone posts :(

I have also tried setting iDisplayStart to 0 on initialisation of the datatable, but that also hasn't worked:

[code]"iDisplayStart" : 0,[/code]

Why are you passing false as the second parameter? That will cause the table to not redraw and thus the page won't appear to have changed.

"I am a beginner to DataTables and this is some existing (working) code I have to maintain..."

Passing true did the the trick...

I assumed the initialisation was doing a draw, so I didn't think I would want to redraw it.. (i.e. perform two draws for one search)

Got it. Good to hear the change worked :-)
