I want to use a two way binding for a checkbox, but if I use the [(ngModel)]
it is showing true or false instead of the value of the checked item. Does anybody know how this is done?
If i want to use a two way binding and set it to "expression.value" in my case how do i do that:
<input type="checkbox" type="checkbox"/> Option 1</a></li>
I would like to bind the value of the checkbox in this case: Option 1 into the expression class.
This is a known issue
There are different workarounds like using event.target.checked
instead of the value from the model.
You can use
<input type="checkbox"
(change)="expression && expression.Option1=$event.target.checked ? true : undefiend"
[ngModel]="expression?.Option1">
<input type="checkbox"
(change)="expression && expression.Option2=$event.target.checked ? true : undefiend"
[ngModel]="expression?.Option2">
