Answer 1

var Arrayvalue = ["a","b","c"];
var matchstring = "v";
if (Arrayvalue .indexOf(matchstring) > -1) {
  // if it is matches the array it comes to this condition
} else {
  // if it is matches the array it comes to this condition
}

The indexOf() method searches the your array for the specified item, and returns its position.
