目标号码输入变化

Question

我有一个数字输入字段，我想在使用向上/向下按钮增加或减少数字或用户输入价格时显示我的价格的实时更新。这是我到目前为止所拥有的。它怎么能有针对性地做到这一点？ HTML

<table>
  <tr>  
    <td>QUANTITY: <input type="number" style="width: 50px "ng-model="quant" ng-init="quant = 1"/></td>
    <td>TOTAL:{{total}}</td>
    <td><button ng-click="goPrice(quant)">PRICE</button></td>
  </tr>
</table>

控制器

$scope.goPrice = function(quant){
    $scope.total= quant * 9.99
    console.log($scope.total)
}

Answer 1

也许这对你有帮助

<input
  ng-model="string"
  [name="string"]
  [required="string"]
  [ng-required="boolean"]
  [ng-minlength="number"]
  [ng-maxlength="number"]
  [ng-pattern="string"]
  [ng-change="expression"]
  [ng-trim="boolean"]>
...
</input>

特别是这个

[ng-change="expression"]
ng-change="change()"
