问如何在javascript中使用子字符串值找到数组的索引并替换为新的字符串？

["1-2","10-4","2-3","3-1","4-4","5-2","6-4","7-3","8-1","9-2"]

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

function GetOption(event, event1) {
   debugger;

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

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

   var getValue = event + "-" + event1;

   if (getValue == "undefined-undefined") {
      getName.push("");
   } else {
      getName.push(getValue);
      getName.sort();
      alert(getName);
   }

   $("#resultHidden").val(getName);
}
