How do I disable/enable a form element?
Sometimes you need to enable or disable input elements or form elements in jQuery. In such cases, you can use jQuery prop[] method to disable or enable input elements/form elements dynamically using jQuery.
example

jQuery 1.5 and below
The jQuery .prop[] method doesn't exist jQuery 1.5 and below , in such cases you can use jQuery .attr[] method .
It is important to note that, you can always rely on the actual DOM object and is probably a little faster than the above two options if you are only dealing with one element:
JavaScript
In JavaScript you can use the following code to disable/enable an element.
The disabled property sets or returns whether a text field is disabled, or not.
This page describes how to perform these tasks
involving labels: Disabling a label results in a new disabled published revision based on the current published revision. If there's a draft revision, a new disabled draft revision is created based on the latest draft revision. Older draft revisions are deleted. For more information, see
Label lifecycle. Once disabled, users can still apply this label through the API. The label still appears where it's already been applied and in your search results. A disabled label can be deleted.Disable a label
To disable a published label, use the
disable
method on the labels
collection.
You also need to specify:
A Label resource which represents every label. It contains a resource
Name
andID
, which is a globally unique identifier for the label.useAdminAccess
istrue
to use the user's administrator credentials. The server verifies the user is an admin for the label before allowing access.
This example uses the ID
to disable the correct label.
Python
service.labels[].disable[
name='labels/ID',
body={
'use_admin_access': True
}].execute[]
Node.js
service.labels.disable[{
'resource': {
'use_admin_access': true
},
'name': 'labels/ID'
}, [err, res] => {
if [err] return console.error['The API returned an error: ' + err];
console.log[res];
}];
The label has the
State
of DISABLED
and the label's revision ID is incremented. Users can apply the label through the API. However, a disabled label is not shown in a UI unless the showInApply
property of the disabledPolicy
method is configured.
Enable a label
Enabling a disabled label restores it to its published state. It results in a new published revision based on the current disabled published revision. If there's an existing disabled draft revision, a new revision is created based on that draft and is enabled. For more information, see Label lifecycle.
To enable a disabled label, use the
enable
method.
You also need to specify:
A Label resource which represents every label. It contains a resource
Name
andID
, which is a globally unique identifier for the label.useAdminAccess
istrue
to use the user's administrator credentials. The server verifies the user is an admin for the label before allowing access.
This example uses the ID
to enable the correct label.
Python
service.labels[].enable[
name='labels/ID',
body={
'use_admin_access': True
}].execute[]
Node.js
service.labels.enable[{
'resource': {
'use_admin_access': true
},
'name': 'labels/ID'
}, [err, res] => {
if [err] return console.error['The API returned an error: ' + err];
console.log[res];
}];
The label has the State
of
PUBLISHED
and the label's revision ID is incremented. Users can view and apply the label to files through the API.
Delete a label
Only draft and disabled labels can be deleted. When a label is deleted, all instances where the label was previously applied, including any corresponding field values entered by users, are permanently deleted and removed from those Drive files.
To delete a label, you must
first disable it and then use the delete
method.
You also need to specify:
A Label resource which represents every label. It contains a resource
Name
andID
, which is a globally unique identifier for the label.useAdminAccess
istrue
to use the user's administrator credentials. The server verifies the user is an admin for the label before allowing access.
This example uses the ID
to delete the correct label.
Python
response = service.labels[].delete[
name='labels/ID',
useAdminAccess=True].execute[]
Node.js
service.labels.delete[{
'name': 'labels/ID',
'use_admin_access': true
}, [err, res] => {
if [err] return console.error['The API returned an error: ' + err];
console.log[res];
}];
The label has the
State
of DELETED
and the label's revision ID is incremented. The label cannot be applied and deleted labels are eventually purged. For more information, see Label lifecycle.
