ng-change值未进入角度控制器

Question

In html

<input type="number" min="0" max="1000" class="form-control" ng-model="eachvalue.hours" ng-change="updateHour(eachvalue);" placeholder="Hours" required>

In Controller

 $scope.updateHour = function (val) {
    console.log(val);
  }

I m not getting the value of 10.100 on controller when changing the number text box , here i can only console the value of 10.1

Can anyone know how to resolve the issue ?????????

Answer 1

By using ng-model , the value is already (two-way-)bound to $scope.eachvalue.hours . It will always be up-to-date, no need to use ng-change and pass a value to it.

 $scope.updateHour = function () {
  console.log($scope.eachvalue.hours);
 }

Answer 2

you can change your HTML also instaed

ng-change="updateHour(eachvalue)

TO

ng-change="updateHour(eachvalue.hours)

Answer 3

您可以尝试像这样定义eachvalue.hours，以便将其绑定：

$scope.eachvalue = { hours: 0 };
