Question

我正在尝试传递ng-model="alertThreshold.value"的值，但是当我点击<a class="spin-up" data-spin="up" ng-click = "getAlertThreshold(alertThreshold.value)"><i class="fa fa-caret-up"></i></a>或<a class="spin-down" data-spin="down ng-click = "getAlertThreshold(alertThreshold.value)"" ><i class="fa fa-caret-down"></i></a>时它只是调用函数而不更新值，值总是= 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>

并在我的控制器中：

$scope.alertThreshold = {
        value: 10
    };

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

Answer 1

$scope.alertThreshold.value的值始终相同，因为获取输入的值。就像$scope.alertThreshold.value = $scope.alertThreshold.value每ng-click或ng-change

一样

Answer 2

ng-click =“getAlertThreshold（++ alertThreshold.value）”ng-click =“getAlertThreshold（ - alertThreshold.value）”可以解决问题。

如何使用ng-click将值传递给角度函数
