Definition and Usage
The ng-checked
directive sets the checked attribute of a
checkbox or a radiobutton.
The checkbox, or radiobutton, will be checked if the expression inside the
ng-checked
attribute returns true.
The ng-checked
directive is necessary to be able to shift the
value between true
and false
. In HTML, you cannot set
the checked
attribute to false
(the presence of the
checked attribute makes the element checked, regardless of its value).
Syntax
<input type="checkbox|radio" ng-checked="expression"></input>
Supported by <input> elements of type checkbox or radio.
