angularjs – 如果选中复选框,则需要输入值

HTML：

<div style="width: 100%;">
<checkboxgroup-Wheelbase min-required="1">          
    <table style="width: 100%">                                
        <tr>
            <td>
                <table style="width: 97%;">
                    <tr>
                        <th style="width: 220px;" class="wheelbaseHeaderCell">Wheelbase<br /><span style="font-weight: 400;">(choose min of 1)</span></th>
                        <th class="wheelbaseHeaderCell">Payload<br />[ pounds ]</th>

要求至少一个复选框的指令：

.directive('checkboxgroupWheelbase',function() {
    return {
        restrict: 'E',controller: function($scope,$attrs) {
            var self = this;
            var ngModels = [];
            var minRequired;
            self.validate = function() {
                var checkedCount = 0;
                angular.forEach(ngModels,function(ngModel) {
                    if (ngModel.$modelValue) {
                        checkedCount++;
                    }
                });
                console.log('minRequired',minRequired);
                console.log('checkedCount',checkedCount);
                var minRequiredValidity = checkedCount >= minRequired;
                angular.forEach(ngModels,function(ngModel) {
                    ngModel.$setValidity('checkboxgroupWheelbase-minRequired',minRequiredValidity,self);
                });
            };

            self.register = function(ngModel) {
                ngModels.push(ngModel);
            };

            self.deregister = function(ngModel) {
                var index = this.ngModels.indexOf(ngModel);
                if (index != -1) {
                    this.ngModels.splice(index,1);
                }
            };

            $scope.$watch($attrs.minRequired,function(value) {
                minRequired = parseInt(value,10);
                self.validate();
            });
        }
    };
})

有没有一个简单，优雅的方式来要求检查这些复选框的输入字段是必需的？通过“规则”在JQuery中看起来很直观，但是我没有找到一种方法来通过AngularJs来实现。有人建议我使用子表格，但我不能设想它的含义。

如果我不清楚：

对于检查相应复选框的任何行，该行的所有输入都需要具有值。所以，如果检查说第1,3和5行的复选框，则行1,3和5的输入需要值。如果选中一行的复选框，同一行的输入需要一个值。如果该行的复选框未选中，则不需要输入。在清理它之后，它让我觉得一个明智的事情将是所有输入被禁用，直到他们各自的轴距复选框被选中。

更新：

我想感谢user2104976让我想起一个更好的用户体验，只要在不检查相应的轴距复选框时确保输入值不被添加，那么我实现了

**"ng-disabled="!wheelbase.checked"**

在每个相应的输入中。多谢，伙计！！现在怎么解决我原来的问题，LOL！
