To set focus to an HTML form element, the focus() method of JavaScript can be used. To do so, call this method on an object of the element that is to be focused, as shown in the example.
Example 1: The focus() method is set to the input tag when user clicks on Focus button.
<!DOCTYPE html>
<html>
<head>
<title>
Set focus to HTML form element
</title>
</head>
<body>
<p>
Click on button to set focus
on input field
</p>
<form>
<input type="text" id="input1">
<br><br>
<button type="button" onclick="focusInput()">
Set Focus
</button>
</form>
<script>
function focusInput() {
document.getElementById("input1").focus();
}
</script>
</body>
</html>
|
Output:

}
</script>
