Use the onsearch attribute in HTML to execute a script when the user writes in a search field and press ENTER or x.
Example
You can try to run the following code to implement the onsearch attribute −
<!DOCTYPE html>
<html>
<body>
<p>Search something and press ENTER.</p>
<input type = "search" id="inputID" onsearch = "display()">
<p><strong>Note:</strong> It won' work in Internet Explorer and Firefox.</p>
<p id="test"></p>
<script>
function display() {
var a = document.getElementById("inputID");
document.getElementById("test").innerHTML = "Searched for - " + a.value;
}
</script>
</body>
</html>
