[javascript] 숫자만 입력 받도록 처리

1. 자바스크립트 단

function onlyNumber(event){ event = event || window.event; var keyID = (event.which) ? event.which : event.keyCode; if ( (keyID >= 48 && keyID <= 57) || (keyID >= 96 && keyID <= 105) || keyID == 8 || keyID == 9 || keyID == 46 || keyID == 37 || keyID == 39 ) { return; } else { return false; } } function removeChar(event) { event = event || window.event; var keyID = (event.which) ? event.which : event.keyCode; if ( keyID == 8 || keyID == 9 || keyID == 46 || keyID == 37 || keyID == 39 ) { return; } else { event.target.value = event.target.value.replace(/[^0-9]/g, ""); } }

2. HTML 단

<input type="text" name="num" onkeydown="return onlyNumber(event);" onkeyup="removeChar(event);" style="ime-mode:disabled;" />
