When a jQuery set attribute is set to “readonly”, the attribute’s value cannot be changed. This can be useful when you want to prevent users from changing the value of an attribute, or when you need to ensure that the attribute’s value is always the same.
This code line is using the jQuery attr() method to set the readonly attribute of an element with the id of “input” to “readonly”. This will make the element read only so that users cannot edit it.

To create a radio button, you use the $(“input[type=’radio’]”) object.
To create a file input, you use the $(“input[type=’file’]”) object.
