Look to the console: "as" is not defined (line 29 and 95), function in parameter "ta" not used inside function.

Why you do not use a switch? It would be more convenient here:

function kal(ta){
    var xy=ta,x1,x2,x3,x4;
    switch(xy){
        case 1: x1=0; x2=1; x3=1; x4=1; break;
        case 2: x1=1; x2=0; x3=1; x4=0; break;
        case 3: x1=0; x2=1; x3=0; x4=1; break;
        case 4: x1=1; x2=1; x3=1; x4=1; break;
        case 5: x1=0; x2=0; x3=1; x4=0; break;
        case 6: x1=0; x2=1; x3=1; x4=0; break;
        case 7: x1=1; x2=1; x3=1; x4=0; break;
        case 8: x1=1; x2=0; x3=1; x4=1; break;
        case 9: x1=1; x2=1; x3=0; x4=1; break;
        case 10: x1=0; x2=0; x3=1; x4=1; break;
        case 11: x1=1; x2=1; x3=0; x4=0; break;
        case 12: x1=0; x2=0; x3=0; x4=1; break;
        case 13: x1=0; x2=1; x3=0; x4=0; break;
        case 14: x1=1; x2=0; x3=0; x4=0; break;
        case 15: x1=1; x2=0; x3=0; x4=1; break;
        case 16: x1=0; x2=0; x3=0; x4=0; break;
    }
    this.xa = x1;
    this.xb = x2;
    this.xc = x3;
    this.xd = x4;
    return this;
}
