Question

我有一个数字输入字段，我想显示我的价格的实时更新，当使用向上/向下按钮增加或减少数字或用户输入价格时。这是我到目前为止所拥有的。它如何以此为目标？ 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>

CONTROLLER

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

也许这可以帮到你

<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()"

目标号码输入更改
