How to check if array contains specific element?
You can use jQuery’s inArray function. Ie, to check if array myArray contains number 10 in it, you can use next code: if ($.inArray( myArray, 10) !== -1) { alert(“Yes, array myArray contains number 10 as one of it’s elements!”); } else { alert(“Nope, array myArray doesn’t contains number 10!”); }
