| [ASK] saya mencoba membuat aplikasi perhitungan m... Sep 18th 2013, 17:54, by Andrew Chandra Raniello | | [ASK]
saya mencoba membuat aplikasi perhitungan menggunakan event keyup jquery menggunakan "jquery-1.8.3.min.js",dimana fungsi dari event keyup disini apabila ada respon menggunakan keyboard maka fungsi yang ada didalamnya akan di laksanakan.
saya bingung ketika mencoba menampilkan secara otomatis pd text total knp ga da nilainya yah??, brikut codenya
<script src="jquery-1.8.3.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function(){
function hitung() {
var harga = $("#harga").val();
var jumlah = $("#jumlah").val();
var trip = $("#trip").val();
var hrg_tiket = $("#hrg_tiket").val();
if(harga>0 && jumlah>0 && trip>0 && hrg_tiket>0){
var total = parseInt(harga)*parseInt(jumlah)*parseInt(trip)+parseInt(hrg_tiket);
$("#total").val(total);
diskon();
bonus();
}else{
$("#total").val('');
$("#diskon").val('');
$("#bonus").val('');
}
}
function diskon(){
var total = $("#total").val();
if(total>=500000){
var diskon = parseInt(total)*20/100;
$("#diskon").val(diskon);
}else if(total>=200000){
var diskon = parseInt(total)*15/100;
$("#diskon").val(diskon);
}else if(total>=100000){
var diskon = parseInt(total)*10/100;
$("#diskon").val(diskon);
}else if(total>=50000){
var diskon = parseInt(total)*5/100;
$("#diskon").val(diskon);
}else{
$("#diskon").val(0);
}
}
function bonus(){
var total = $("#total").val();
if(total>=500000){
var bonus = 'Tas Pinggang';
$("#bonus").val(bonus);
}else if(total>=200000){
var bonus = 'Payung';
$("#bonus").val(bonus);
}else if(total>=100000){
var bonus = 'Kaos';
$("#bonus").val(bonus);
}else if(total>=50000){
var bonus = 'Cangkir';
$("#bonus").val(bonus);
}else{
$("#bonus").val('Tidak Ada');
}
}
$("#harga").keyup(function(){
hitung();
});
$("#jumlah").keyup(function(){
hitung();
});
$("#trip").keyup(function(){
hitung();
});
$("#hrg_tiket").keyup(function(){
hitung();
});
});
</script>
