How to use regex match in string array?

Question

I want to this : When the entered value matches the value of the my array , write the matches value.

so this is my code :

//my array as the following :

var checkNames = (document.getElementById("KPIorCounterList").value.split("\n").map(element => element.trim())).filter(v=>v != "");

my another array : myarray= ["RAB Video call drop %",RAB PS R99 drop % ","RAB PS HSDPA drop %"]

For example ; when write RAB* to textare, I should to see, starting with "RAB"

I guess, My code should be as follows:

  for (var i = 0; i < checkNames.length; i++) {
                    for (var j = 0; j < myarray.length; j++) {
           // var str = myarray[j].split(" "); // I am not sure for his.

            I want to this for here : (pseudo code)
            for example checkName[i] == RAB*
            if (checkName[i].match("match condition") == myarray[j])
            alert(myarray[j]);
            //I should show output myarray[j] == RAB Video call drop %",RAB PS R99 drop % ","RAB PS HSDPA drop %"
       }
    }

How can I do ? Please..

Answer 1

function check(){
var checkNames = (document.getElementById("KPIorCounterList").value.split("\n").map(element => element.trim())).filter(v=>v != "");
var myarray = ["RAB Video call drop %", "RAB PS R99 drop % ", "RAB PS HSDPA drop %"]
for (var i = 0; i < checkNames.length; i++) {
  console.log("results for", checkNames[i])
  for (var j = 0; j < myarray.length; j++) {

      var matchString = myarray[j].match(new RegExp(checkNames[i].replace('*','.*')));
    if (matchString && myarray.indexOf(matchString[0])!==-1) {
      console.log(myarray[j]);
    }
    //I should show output myarray[j] == RAB Video call drop %",RAB PS R99 drop % ","RAB PS HSDPA drop %"
  }
}
  }
