fnfilter for each column ?

bzbz

HI.
i would like to use a filter for each column with checkbox.
For just one column it's ok but i don't know how use the script to add the same filter for others.
Thanks.

Not quite sure I understand I'm afraid. You are already using fnFilter to limit the column filter to a single column (the first, `0` , column in your example). Would you not just do the same again with the other column indexes?

Hi allan.
Yes i just want to do the same again with each columns indexes.
$('#example').dataTable().fnFilter(filter, 0, regexFilter, smartFilter);
$('#example').dataTable().fnFilter(filter, 1, regexFilter, smartFilter);
$('#example').dataTable().fnFilter(filter, 2, regexFilter, smartFilter);
.....
it may be simple, but I'm not familiar with the javascript language. I tested things without success...

Thanks.

You are passing in the same value of `filter` (etc) into the search for each column. Is that what you want to do?

no i don't want passing same value. I want a filter by column, but i don't know where write it.
Maybe you're understand with this ie (it not work...):

I'm afraid I don't really understand. You've got some code which works for filtering one column:

[code]

$(':checkbox[name="rendering_filter"]').click(function() {
var filter = '',
regexFilter = true,
smartFilter = false;

filter = $('[name="' + this.name + '"]:checked').map(function () {
return this.value;
}).toArray().join('|');

$('#example').dataTable().fnFilter(filter, 0, regexFilter, smartFilter);
});
[/code]

Why not duplicate it for the other columns?

Better yet would be to put it in a function and call it, passing in the column index you want to filter on, so you don't have large amounts of duplicate code.
