Javascript - Loop

atomic · January 1, 2015

Salam tahun baru untuk semua..

saya nak bertanya logik pasal loop javascript nih, dah pening pikir...

boleh test script kat sinih : http://www.w3schools.com/js/tryit.asp?filename=tryjs_alert

saya sertakan contoh :

HTML:

<!DOCTYPE html>
<html>
<body>
<form id="myform" name="myform">
<table>
    <tr>
        <td valign="top">
            1.<input type="textbox" name="txtnama" value="Abu">
        </td>
        <td>
          <input type="radio" name="rbostatus1" value="Hadir">Hadir
          <input type="radio" name="rbostatus1" value="Tidak Hadir">Tidak Hadir
        </td>
    </tr>
     <tr>
        <td valign="top">
            2.<input type="textbox" name="txtnama" value="Ali">
        </td>
        <td>
          <input type="radio" name="rbostatus2" value="Hadir">Hadir
          <input type="radio" name="rbostatus2" value="Tidak Hadir">Tidak Hadir
        </td>
    </tr>
 <tr>
        <td valign="top">
             3.<input type="textbox" name="txtnama" value="Amin">
        </td>
        <td>
          <input type="radio" name="rbostatus3" value="Hadir">Hadir
          <input type="radio" name="rbostatus3" value="Tidak Hadir">Tidak Hadir
        </td>
    </tr>
</table>
</form>
                <button type="button" onclick="getRadioValue()">test</button>
</body>
</html>

SCRIPT :

<script>
    function getRadioValue() {
        var abc = '';
        
        var MyElements = document.myform.elements;
        for (var x = 0; x < MyElements.length; x++) {
            if (MyElements[x].name === "txtnama") {
                abc +="\r\n" + "<nama>" + MyElements[x].value + "</nama>";
            }
            if (MyElements[x].type === "radio") {
                if (MyElements[x].checked) {
                    abc +="\r\n" + "<kehadiran>" + MyElements[x].value + "</kehadiran>";
                } 
                else {
                    abc += "\r\n" + "<kehadiran></kehadiran>";
                }
            }
        }
        alert(abc);
    }
</script>

Result sekarang :

<nama>Abu</nama>
<kehadiran>Hadir</kehadiran>
<kehadiran></kehadiran>
<nama>Ali</nama>
<kehadiran></kehadiran>
<kehadiran>Tidak Hadir</kehadiran>
<nama>Amin</nama>
<kehadiran>Hadir</kehadiran>
<kehadiran></kehadiran>

Result sepatutnya :

<nama>Abu</nama>
<kehadiran>Hadir</kehadiran>
<nama>Ali</nama>
<kehadiran>Tidak Hadir</kehadiran>
<nama>Amin</nama>
<kehadiran>Hadir</kehadiran>

atau

<nama>Abu</nama>
<kehadiran>Hadir</kehadiran>
<nama>Ali</nama>
<kehadiran>Tidak Hadir</kehadiran>
<nama>Amin</nama>
<kehadiran></kehadiran> * kosong sebab tak tick

saya harap ada yang sudi bantu..

<script>
    function getRadioValue() {
        var strA = '';
        var strB = '';

        var myElements = document.myform.elements;
        for (var x = 0; x < myElements.length; x++) {
            if (myElements[x].name=== "name") {
                if (strA === '') {
                    strA = myElements[x].value;
                } else {
                    strA += "$" + myElements[x].value;
                }
            }
            if (myElements[x].type === "radio") {
                if (myElements[x].checked) {
                    if (strB === '') {
                        strB = "$" + myElements[x].value;
                    } else {
                        strB += "$" + myElements[x].value;
                    }
                }
            }
        }

        var test = '';

        var strFirst = strA.split('$');
        var strSecond = strB.split('$');
alert(strB);
alert(strSecond[0]);
alert(strSecond[1]);
//alert(strSecond[2]);
        for (var i = 0; i < strFirst.length; i++) {
//alert(strSecond[i]);
            if ((strSecond[i]=== '') || (typeof strSecond[i] === 'undefined')) {
//alert(strSecond[i]);
//alert('masuk1');
                test += "\r<nama>" + strFirst[i] + "</nama><kehadiran></kehadiran>";
            } else {
//alert(strSecond[i]);
//alert('masuk2');
                test += "\r<nama>" + strFirst[i] + "</nama></kehadiran>" + strSecond[i] + "</kehadiran>";
            }
        }
        alert(test);
    }
</script>

Alhamdulillah..akhirnya selesai...

ni code dia :

<script>
function getRadioValue() {
    var e = document.myform.elements;
    var t = "";
    var n = "";
    var r = 0;
    var i = "";
    for (var s = 0; s < e.length; s++) {
        if (e[s].type !== "radio") {
            t += "\r\n" + "<Nama>" + e[s].value + "</Nama>"
        } else {
            r = n != e[s].name ? 1 : 2;
            if (e[s].checked) {
                i = "\r\n" + "<Kehadiran>" + e[s].value + "</Kehadiran>"
            } else {
                if (r == 1) i = "\r\n" + "<Kehadiran></Kehadiran>"
            }
            if (r == 2) {
                t += i;
                i = ""
            }
            n = e[s].name
        }
    }
    alert(t)
}
</script>
