জাভা-স্ক্রিপ্ট দিয়ে আমরা খুব সহজে কি-বোর্ড বাটন প্রেস ধরতে পারি।
নিম্ন পদ্ধতিতে ঃ
$(document).ready(function () {
document.addEventListener("keydown", keyPress, false);
)
});
function keyPress(e) {
var keyCode = e.keyCode;
// এই কি কোড ভালু ধরে অ্যাকশান ধরা যায়।
if (keyCode === 13) {
alert("You Press Enter");
}
if (keyCode === 113) {
alert("You Press F2");
}
if (keyCode === 114) {
alert("You Press F3");
}
if (keyCode === 115) {
alert("You Press F4");
}
if (keyCode === 117) {
alert("You Press F6");
}
if (keyCode === 119) {
alert("You Press F8");
}
if (keyCode === 120) {
alert("You Press F9");
