Pass checkbox value to angular's ng-click

Is there a way to pass to angular directive ng-click the value of the associated input?

In other words, what should replace this.value in the following:

<input type="checkbox" id="cb1" ng-click="checkAll(this.value)" />

PS. I don't want a workaround to alternate values, I just wonder if is possible to pass a value of an input as argument to an angular function.

You can do the following things:

  • Use ng-model if you want to bind a html component to angular scope
  • Change ng-click to ng-change
  • If you have to bind some value upon checking and un-checking the checkbox use ng-true-value="someValue" and ng-false-value="someValue"

The order of execution of ng-click and ng-model is ambiguous since they do not define clear priorities. Instead you should use ng-change or a $watch on the $scope to ensure that you obtain the correct values of the model variable.
