當(dāng)輸入值為空時，我嘗試 setCustomValidity，它正在工作，但問題是錯誤彈出窗口不斷顯示消息（當(dāng)輸入處于焦點時）...function chec() { inn = document.getElementById('num'); if (inn.value == "") { inn.setCustomValidity("Empty"); } else { inn.setCustomValidity(""); }}<form><input type="number" id="num" min="20" max="50" required><input type="submit" onclick="chec()"></form>
setCustomValidity“空”
