var myArray = [1, 2, 3, 4, 5];
var searchValue = 3;

if ($.inArray(searchValue, myArray) !== -1) {
    console.log("Value exists in array");
} else {
    console.log("Value does not exist in array");
}

var myArray = [1, 2, 3, 4, 5];
var searchValue = 3;

if (myArray.indexOf(searchValue) !== -1) {
    console.log("Value exists in array");
