Sometimes you need to disable or enable some elements in your document and jQuery makes this task easy. All you have to do is to set disabled attribute to “disabled”.

Example:

// To disable 
$('.someElement').attr('disabled', 'disabled');

In order to enable any disabled element you need to set the disabled attribute to empty string or remove it entirely like in the code below.

// To enable 
$('.someElement').removeAttr('disabled');

// OR you can set attr to "" 
$('.someElement').attr('disabled', '');
