If an element’s value is greater than its max attribute then rangeOverflow property returns true. For example, the below form submission throws an error if the value is more than 100,
1 2 | <input id="age" type="number" max="100"> <button onclick="myOverflowFunction()">OK</button> |
1 2 3 4 5 | function myOverflowFunction() { if (document.getElementById("age").validity.rangeOverflow) { alert("The mentioned age is not allowed"); } } |
