我有三个按钮:
<button class="btn btn-success">Save</button>
<button class="btn btn-success">Send</button>
<button class="btn btn-success">Close</button>
我想知道如何隐藏条件按钮?
答案 0 :(得分:2)
<button ng-show="ShowSave" class="btn btn-success">Save</button>
<button ng-show="ShowSend" class="btn btn-success">Send</button>
<button ng-show="ShowClose" class="btn btn-success">Close</button>
这里ShowSave,ShowSend,ShowClose将是布尔值,它将在您的控制器中设置
$scope.ShowSave = true;
如果以上是真的,它会显示按钮,如果是假,它会隐藏你的按钮。
现在您可以将其视为条件,如
<button ng-show="ShowSave == true" class="btn btn-success">Save</button>
或者如果您要分配一些字符串值,例如&#39; display&#39;那就像
<button ng-show="ShowSave == 'display' ? true : false" class="btn btn-success">Save</button>

您可以使用ng-show
和ng-hide
甚至ng-if
。让我们看一下如何在您的情况下使用这些指令的示例。例如,我们要显示保存按钮&amp;仅在发送内容后删除发送按钮,如果用户点击关闭按钮,我们不想同时显示保存和发送按钮,下面是如何使用它们的示例代码。
在您的HTML中
<button class="btn btn-success" ng-if="showBtns" ng-show="showSave" ng-click="save()">Save</button>
<button class="btn btn-success" ng-if="showBtns" ng-hide="showSave "ng-click="send()">Send</button>
<button class="btn btn-success" ng-click="close()">Close</button>
在你的JS中
$scope.showSave = false;
$scope.showBtns = true;
$scope.send= function(){
$scope.showSave = true;
};
$scope.close = function(){
$scope.showBtns =false;
}
以下是article关于何时使用ng-show / ng-hide和ng-if.Hope这对你有帮助!
