Masih berhubungan dengan postingan sebelumnya tentang Error Handling (Input Number Only), nah disini gue bakal gunain teknik yang biasa gua gunain buat nutupin bug supaya nggak bisa nginputin angka di form untuk perhitungan. Kalau dipostingan sebelumnya kita ngomongin C++, disini kita bakal ngomongin tentang jquery.
Ini dia baris kode buat ngedisable keyboard key selain angka, backspace, dan arah atas,bawah,kanan,kiri yang gua buat di salah satu project akhir salah satu mata kuliah gue disemester ini.
function disableKey(x){
$(“#”+x).keydown(function(event) {
if (event.which==8 ||event.which==9|| event.which==46 || event.which>=37 && event.which<=40){
return true;
}
else if(event.which>=48&&event.which<=57){
return true;
}
else{
return false;
}
});}
