var getName = new Array();
var temp = new Array();

function GetOption(event, event1) {

      var x = getName.indexOf(event);
      getName.splice(x - 1, 1);
      getName.includes(event);
   }

   this.event1 = event1;
   temp.push(event);

   var getValue = event + "-" + event1;

var items = ["1-2","10-4","2-3","3-1","4-4","5-2","6-4","7-3","8-1","9-2"];
var searchItems = "1-2";
var newItems = "2-1";
for (var i = 0; i < items.length; i++) {
    if (items[i].startsWith(searchItems)) {
        items[i] = newItems;
    }
}
