How can I use multiple checkbox filter?

How can I use multiple checkbox filter?

Right now, this filter is working when my single checkbox is checked:

$('#sportsNBA').on('change', function() {
    if( $(this).is(':checked') ) {
        table.columns(1).search('nba');
    }
    table.draw();
});

However, if I create another one, like so:

$('#sportsNFL').on('change', function() {
    if( $(this).is(':checked') ) {
        table.columns(1).search('nfl');
    }
    table.draw();
});

It only takes the second one in consideration.

What I'm basically looking for, is have many checkboxes with filters and allow the user to check as many as he wants and have it filter from the initial data in the table.

UPDATE: I've seen how to make it work with previous versions, but not the current one: http://plnkr.co/edit/b8cLVaVlbNKOQhDwI2mw

    Thats an interesting example. You need to look at the script.js to see how the search is being executed. The Conversion Guide from 1.9 to 1.10 will help you map to the current naming convention.

    fnFilter maps to search() and the search type is regex. The script is actually using column().search(). Using column().search() you can setup a similar function to perform a regex search using the checked items.

    But I've tried many things and can't get it to work.
    Some filters will be conducted on column 1, some others on column 2, etc...

    Answer ✓

    There are two problems with your code snippets:

    1. You aren't using regex searching
    2. The searches are executed individually, meaning clicking nba will only search for nba then when clicking nfl the search will only be for nfl.

    I took the code from the working example you posted and updated it for Datatables 1.10 naming convention:

    Great post!
    But what if i want the following:
    If i check single checkbox to filter the Datatable with values not (nba and nfl).
    e.g. show everything except nba and nfl.

    in this case,is this necessary??

                var offices = $('input:checkbox[name="ofc"]:checked').map(function() {
                 return this.value;
                }).get().join('|');
    

    thank you in advance.

    You still need to use regex searches and use | to separate the words to remove from the display. You will need a not type search. Something line this: ^((?!nba|nfl).*)$. I updated the above example to show this with the Position column. The Office column still filters the table showing what is checked.

    Note: The search looks like this search(positions ? '^((?!' + positions + ').*)$' : '', true, false, false). This is to use '' if positions is blank. Otherwise with no checkboxes checked the table will be blank.

    Thank you for the quick reply!

    I think i need something easier than that.

    I just want the first checkbox (eg. chk1) to remove 'Director' and 'Integration Specialist' (only these 2)
    and the second checkbox (eg. chk2) to remove 'New York' and 'San Francisco' (only these 2).

    In this case,do i need the following code??

                 var positions = $('input:checkbox[name="pos"]:checked').map(function() {
                 return this.value;
                 }).get().join('|');
    
                 table.column(1).search(positions ? '^((?!' + positions + ').*)$' : '', true, false,                         false).draw(false);

    Like I said you will need a regex search. This regex seems to work ^((?!nba|nfl).*)$. The | is an or operator for regex. If you want to search for or remove 'Director' or 'Integration Specialist' you will need to use an or search and use | between search terms. Is this answering your question?

    kthorngren considering your answer I follow the example here but in the second checkbox it doesnt filter

     $('input:checkbox').on('change', function () {
       //build a regex filter string with an or(|) condition
        var site = $('input:checkbox[name="site"]:checked').map(function() {
            return this.value === 'on' ? 'S' : 'N';
        }).get().join('|');        
    
        //filter in column 5, with an regex, no smart filtering, not case sensitive        
        table.column(5).search(site, true, false, false).draw(false);
        
        var boca = $('input:checkbox[name="boca"]:checked').map(function() {
            return this.value === 'on' ? 'S' : 'N';
        }).get().join('|');   
        
        console.log(boca);
    
        table.column(6).search(boca, true, false, false).draw(false);    
         
    
      });
    

    someone could help? note that i have 4 checkboxes, which one has the S or N value inside
