function includes in javascript

Question

I want to get the same value on string after split

If I have the numbers (as a string): 1,6,18,2 and I use .includes I get an output which looks like this: 1,2,6,8,18

How can I get same with that string -> 1,2,6,18

This is my code in js :

trHTML = '';    
total = 20; 
var antrian = $('#antrian').val(); // 1,6,18,2

for(i = 1; i <= total; i++){
   if(antrian.includes(i)){
     trHTML += <button style="background-color: gray;"> '+ i +'</button>';
   } else {
     trHTML += <button style="background-color: red;"> '+ i +'</button>';  
   }
}

From that code I got button output button with number, if I consol.log(trHTML) the output is 1,2,6,18 but output in HTML is gray button 1,2,6,8,18 and others is red button

How can I got grey button with number 1,2,6,18 or same with console.log(trHTML) ?

Can someone help me or give me an example?

The reason why 8 is included in 1,6,18,2 is that there is an 8 in the string. One option is make antrian an array using split()

var trHTML = '';    //Add var
var total = 20;     //Add var
var antrian = $('#antrian').val().split(","); //Add split() - this will return to [1,6,18,2]

for(var i = 1; i <= total; i++){ //Add var on i
   if(antrian.includes(i.toString())){
     trHTML += '<button style="background-color: gray;"> '+ i +'</button>';
   } else {
     trHTML += '<button style="background-color: red;"> '+ i +'</button>';  
   }
}
