当ng-show处于活动状态时，禁用我的按钮

Question

我希望在list-of-items处于有效状态时ng-show停用我的按钮

HTML：

<div class="row" ng-show="platform">
    <div class="col-md-12">
        <div class="bg-light">
            <h3>BRIQUES APPLICATIVES COMMUNES</h3>
            <list-of-items items="application.units"
                           label="$item.name"
                           selected-item="unit"
                           selectable="true"
                           onedit="on_edit_unit($item)"
                           editable="false"
                           size="small">
            </list-of-items>
        </div>
    </div>
</div>
<div class="row" ng-show="unit">
..
</div>

JS：

 $scope.on_edit_unit = function (unit) {
...
}
