如何使用ng-click将值传递给角度函数

Question

I'm trying to pass the value of the ng-model="alertThreshold.value" but when I click on <a class="spin-up" data-spin="up" ng-click = "getAlertThreshold(alertThreshold.value)"><i class="fa fa-caret-up"></i></a> or <a class="spin-down" data-spin="down ng-click = "getAlertThreshold(alertThreshold.value)"" ><i class="fa fa-caret-down"></i></a> it just call the function without updating the value, the value is always = 10.

<div class="input-group spinner" data-trigger="spinner">
                          <input type="text" class="form-control text-center" value="0" data-rule="quantity" ng-model="alertThreshold.value" min="0" max="50" ng-change ="getAlertThreshold(alertThreshold.value)">
                          <div class="input-group-addon">
                            <a  class="spin-up" data-spin="up" ng-click = "getAlertThreshold(alertThreshold.value)"><i class="fa fa-caret-up"></i></a>
                            <a  class="spin-down" data-spin="down" ng-click = "getAlertThreshold(alertThreshold.value)"><i class="fa fa-caret-down"></i></a>
                          </div>
                        </div>

and in my controller:

$scope.alertThreshold = {
        value: 10
    };

$scope.getAlertThreshold = function(value){
    console.log("value:",value)
    $scope.alertThreshold.value = value;
}

Answer 1

The value of $scope.alertThreshold.value is always the same because take the value of the input. It's like $scope.alertThreshold.value = $scope.alertThreshold.value every ng-click or ng-change

Answer 2

ng-click =“ getAlertThreshold（++ alertThreshold.value）” ng-click =“ getAlertThreshold（-alertThreshold.value）”可解决此问题。
