I have 4 radiobutton r1,r2,r3,r4. And a date input "tanggal".

in my table i have data in row tanggal 11/15/2018, 11/15/2018, 11/15/2018 11/15/2018

row waktu09.00, 09.20, 09.40, and 10.00

with this query I just can disable one radio button r1 when I choose a date 11/15/2018 with value in my database

<script type="text/javascript">

$(document).ready(function(){

 $('#tanggal').change(function(){

  var tanggalfromfield = $('#tanggal').val();

  $.ajax({        // Memulai ajax

    method: "POST",      

    url: "ajaxtanggal.php",  

    data: {tanggal: tanggalfromfield}   

  })

  .done(function(hasilajax) {

        $('#nama').val(hasilajax);

        var tam=hasilajax;

        if(tam=='09.00WIB'){

            document.getElementById("r1").disabled = true;

        }

    });



 })

});

</script>

when i try to use if else statement nothing change and it's not work.

<script type="text/javascript">

$(document).ready(function(){

 $('#tanggal').change(function(){

  var tanggalfromfield = $('#tanggal').val();  // AMBIL isi dari fiel NPM masukkan variabel 'npmfromfield'

  $.ajax({        // Memulai ajax

    method: "POST",      

    url: "ajaxtanggal.php",    // file PHP yang akan merespon ajax

    data: {tanggal: tanggalfromfield}   // data POST yang akan dikirim

  })

  .done(function(hasilajax) {

        $('#nama').val(hasilajax);

        var tam=hasilajax;

        if(tam=='09.00WIB'){

            document.getElementById("r1").disabled = true;

        }else if(tam=='09.20WIB'){

            document.getElementById("r2").disabled = true;

        }else if(tam=='09.40WIB'){

            document.getElementById("r3").disabled = true;

        }

    });



 })

});

</script>

How to disable r2,r3,r4 when I choose date 11/15/2018?

You need to make standart debugging actions:

1) check tam=='09.00WIB - is this still works? According to code - must be.

2) use

$('#nama').val(hasilajax);

var tam=hasilajax;

console.log('tam:'); console.log(tam);

to see real value of tam. It can be surprisingly not what you expect.

3) add message in various statement to check if it is goes here:

    if(tam=='09.00WIB'){

        document.getElementById("r1").disabled = true;

        console.log('r1 - worked');

    }else if(tam=='09.20WIB'){

        document.getElementById("r2").disabled = true;

        console.log('r2 - worked');

    }else if(tam=='09.40WIB'){

        document.getElementById("r3").disabled = true;

        console.log('r3 - worked');

    } else {

        console.log('nothing of this');

    }

Only then you can understand where is error. Probably not in "if else if"
