다음은 JavaScript의 텍스트 영역에서 화살표 키를 비활성화하는 코드입니다 -

<h1>Disabling arrow keys in a text area</h1>
<textarea class="AreaText">
Hello world this is some sample text inside the text area element
</textarea>
<div class="result"></div>
<button class="Btn" style="margin: 15px;">Disable arrows</button>
<h3>Click on the above button to disable scrolling using arrows in the above textArea</h3>
<script>
let BtnEle = document.querySelector(".Btn");
let resEle = document.querySelector(".result");
BtnEle.addEventListener("click", () => {
window.addEventListener(
"keydown",
(event) => {
if ([32, 37, 38, 39, 40].indexOf(event.keyCode) > -1) {
event.preventDefault();
}
},
false
);
resEle.innerHTML = "Scrolling using arrow keys is disabled";
});
</script>
</body>
</html> 출력
