Use the jQuery prop() method
You can use the jQuery prop() method in combination with the :input selector to disable all <input>, <textarea>, <select> and <button> elements inside an HTML form dynamically using jQuery. The prop() method require jQuery 1.6 and above.
Let's check out an example to understand how this method basically works:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>jQuery Disable All Form Elements</title>
<style>
label {
display: block;
margin-bottom: 5px;
}
label, input, textarea, select {
margin-bottom: 10px;
}
</style>
<script src="https://code.jquery.com/jquery-1.12.4.min.js"></script>
<script>
$(document).ready(function(){
$("#myForm :input").prop("disabled", true);
});
</script>
</head>
<body>
<form id="myForm">
<label>Name:</label>
<input type="text">
<label>Address:</label>
<textarea></textarea>
<label>Country:</label>
<select>
<option>select</option>
</select>
<br>
<button type="button">Submit</button>
<button type="button">Reset</button>
</form>
</body>
</html>
