check uncheck checkbox using angularjs using attribute

Question

I want to add checked and unchecked attribute to the checkbox which is in a table I tried to using it via jquery in angularjs

$('#chksitecolumn_' + item.Id).attr('checked', true)

Here item.Id is the id which I am iterating and binding it on ng-model.

and also tried it using angularjs

var element = angular.element('#chksitecolumn_' + item.Id);
element.attr('checked', 'checked');

but it is not working

Here is my checkbox

<input type="checkbox" class="test"  id="chksitecolumn_{{item.Id}}"
       ng-model="selected[item.Id]"/>

I am passing an ID as a key using ng-model I want to know that can we check uncheck checkbox except using ng-model?

Answer 1

To check/uncheck you can use ng-checked directive (documentation) :

<input type="checkbox" class="test" id="chksitecolumn_{{item.Id}}"
       ng-checked="checked[item.Id]" />

Note that you should not use ng-checked with ng-model together:

Note that this directive should not be used together with ngModel, as this can lead to unexpected behavior.
