We can use .val() method to set the value of a textArea or a input field on a HTML page. Below example demonstrates how we can set the values of both the elements using jQuery. In the example, we are setting the input field value to current system DateTime using Javascript Date() and browser information again using Javascript navigator object.
Syntax:
$('#idOfTheElement').val('value');
Suppose the field name is txtArea1 and value we need to set is “Sample text”, final code to set its value would be:
$('#txtArea1').val('Sample text');
Example:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/css/bootstrap.min.css">
</head>
<body style="padding:10px;background-color:#f5f5f5">
<table class="table table-striped">
<tr>
<td>System DateTime: </td>
<td><input id="txtDate" value="" class="form-control"/></td>
</tr>
<tr>
<td>Browser Info:</td>
<td><textarea id="txtBrowserInfo" class="form-control"></textarea></td>
</tr>
</table>
<script>
$('#txtDate').val(new Date().toLocaleString());
$('#txtBrowserInfo').val(navigator.appName + " Version:" + navigator.appVersion);
</script>
</body>
</html>
