Question

I have a bunch of links that are used to filter information, see: https://i.stack.imgur.com/JHxPL.png

When you click on a link, I add it to an array. For example:

Venue>All = venue-0, Venue>Home = venue-1, Venue>Away = venue-2, 
Vs>All = vs-0, Vs>Lefties = vs-1, Vs>Righties = vs-2
 etc, etc, etc.

If the user clicks “All” in any category, I want to search through the array and remove any items that contain that category. For example: myArray['venue-1','venue-2','vs-1']…click Venue>all, remove 'venue-1' and 'venue-2' leaving myArray['vs-1'].

Can I do this using a regular expression like: /^venue/ and changing the word depending on which “All” you click?

I know I need to do a combination of $.inArray or indexOf() and splice() but I can’t get it working.

You can do this simply with the $.grep utility:

var someArray = [1, 2, 3];

var numbersGreaterThanOne = $.grep(someArray, function(item)
{
    return item > 1;
});

This is just a sample, but you can perform whatever callback to filter elements that you like.
