如何将Ajax中的值分配给数组?

My code is supposed to pass 'seventythree' to php where it will be sent to a MYSQL database and a calculation will be made to calculate efficiency according to the values retrieved from the table seventythree. Afterwards, it's supposed to run again and get the values from seventy four. I used a for loop for this but the result just sends the same value for both the positions 0 and 1 in the array.

function calculateEfficiency(){
    for (x =0; x < 2; x++){
        var y = x+1;
        switch(y){
            case 1:
                mod = "seventythree";
                break;
            case 2:
                mod = "seventyfour";
                break;
        }
        $.ajax({
            type: 'post',
            url: 'efficiency.php',
            dataType: 'json',
            data: {'mod' : mod},
            error: function(){alert("fail");}
        }).done(function(data){
            efficiency = data.efficiency;
            refresh = data.refresh;
        }); 

        efficiencyArray[x] = efficiency;

        if (refresh){

        document.getElementById("efficiency1").innerHTML = efficiencyArray[0];
        document.getElementById("efficiency2").innerHTML = efficiencyArray[1];

        }
    }
}

What do I do?

    What @barmar is saying is that you need to place this:

    efficiencyArray[x] = efficiency;
    
        if (refresh){
    
        document.getElementById("efficiency1").innerHTML = efficiencyArray[0];
        document.getElementById("efficiency2").innerHTML = efficiencyArray[1];
    
        }
    

    Inside of this:

    .done(function(data){
    //inside here
    });
