Can I use a Regular Expression within jQuery.inArray()

Question

I would like the following if statement to alert \'yes\' if \'featured\' is in array, regardless of whether it is uppercase or lowercase.

I\'m also not

Answer 1

You can use $.grep to filter the array and then check the length:

 if ( $.grep( myArray, function (e, i ){ return /featured/i.test(e); }).length > 0 )
    alert( "YES!" );
