大家好我想获取从输入值Buyer_name到Copied Buyer_name输入field.i尝试过很多方法，但无法找到解决办法，如果有人知道的解决方案，请帮助我....我普拉克

控制器：-

$('#supname').change(function() {
$('#supnamecopy').val($(this).val());

});

HTML：

 <label for="quantity">Quantity</label>
      <input type="text" ng-model="state.quantity" id="quantity" typeahead="state as state.quantity for state in states | filter: $viewValue">

 <label for="quantity">Buyer_name</label>
      <input type="text" id="supname" ng-model="state.quantity" typeahead="state.buyer_name  for state in states | filter: $viewValue">

 <label for="quantitycopy">Copied Buyer_name</label>
      <input type="text" name="supnamecopy" id="supnamecopy" ng-model="copied">

我的数据：

    $scope.states = [{
"_id": "5744009c2f0f2bef0ca707ef",

HTML-保持原样

JS-将jQuery更改为角度功能。

目前设置ng模型的方式将$ scope.state.quantity分配为选定状态，而不是该状态的数量值。

$scope.$watch('state.quantity', function() {
    if($scope.state && $scope.state.quantity && $scope.state.quantity.buyer_name) {
        $scope.copied = angular.copy($scope.state.quantity.buyer_name);
    } else {
        $scope.copied = null;
    }
});
