Munculin Otomatis Simbol ribuan di Input Box Form

Biar kolom atau kotak inputan di form menampilkan angka ribuan yang muncuin tanda koma secara otomatis ini skripnya

Tahapannya sebagai berikut:

1. Menyiapkan file JS “numberku.js” ini skripnya
2. Panggil Js itu di skrip html
3. selesai

//isi di file js numberku.js


//start script

function tandaPemisahTitik(b){
var _minus = false;
if (b<0) _minus = true;
b = b.toString();
b=b.replace(".","");
b=b.replace("-","");
c = "";
panjang = b.length;
j = 0;
for (i = panjang; i > 0; i--){
j = j + 1;
if (((j % 3) == 1) && (j != 1)){
c = b.substr(i-1,1) + "." + c;
} else {
c = b.substr(i-1,1) + c;
}
}
if (_minus) c = "-" + c ;
return c;
}

function numbersonly(ini, e){
if (e.keyCode>=49){
if(e.keyCode<=57){
a = ini.value.toString().replace(".","");
b = a.replace(/[^\d]/g,"");
b = (b=="0")?String.fromCharCode(e.keyCode):b + String.fromCharCode(e.keyCode);
ini.value = tandaPemisahTitik(b);
return false;
}
else if(e.keyCode<=105){
if(e.keyCode>=96){
//e.keycode = e.keycode - 47;
a = ini.value.toString().replace(".","");
b = a.replace(/[^\d]/g,"");
b = (b=="0")?String.fromCharCode(e.keyCode-48):b + String.fromCharCode(e.keyCode-48);
ini.value = tandaPemisahTitik(b);
//alert(e.keycode);
return false;
}
else {return false;}
}
else {
return false; }
}else if (e.keyCode==48){
a = ini.value.replace(".","") + String.fromCharCode(e.keyCode);
b = a.replace(/[^\d]/g,"");
if (parseFloat(b)!=0){
ini.value = tandaPemisahTitik(b);
return false;
} else {
return false;
}
}else if (e.keyCode==95){
a = ini.value.replace(".","") + String.fromCharCode(e.keyCode-48);
b = a.replace(/[^\d]/g,"");
if (parseFloat(b)!=0){
ini.value = tandaPemisahTitik(b);
return false;
} else {
return false;
}
}else if (e.keyCode==8 || e.keycode==46){
a = ini.value.replace(".","");
b = a.replace(/[^\d]/g,"");
b = b.substr(0,b.length -1);
if (tandaPemisahTitik(b)!=""){
ini.value = tandaPemisahTitik(b);
} else {
ini.value = "";
}

return false;
} else if (e.keyCode==9){
return true;
} else if (e.keyCode==17){
return true;
} else {
//alert (e.keyCode);
return false;
}

}


//end script



            

Kode Html untuk formnya sebagai berikut

<!--number--->
<script type="text/javascript" src="js/numberku.js"></script>
 <div class="form-group row">
<label class="col-sm-2 col-sm-2 control-label">Angka</label>
 <div class="col-sm-10">
<input type="text" placeholder="Rp. / bulan" name="b51a" class="form-control" id="inputku" onkeydown="return numbersonly(this, event);" onkeyup="javascript:tandaPemisahTitik(this);" value="<?=$row['b51a']?>">      
</div>
</div>
