使用ng-repeat我想使用ng-model和ng-show主观地选择要扩展的区域以更新宠物,地点或点。现在,它显示了ng-repeat中所有p中的p,但我只希望它显示单击的单个p的更新按钮。如果您再次单击更新按钮可以告诉我如何关闭它,请加分。这是我的Angularjs指令的HTML:
<table>
<thead>
<tr>
<th colspan="1" class="text-center">
Pets, Places and Points
</th>
<th colspan="1" class="text-center">
Update
</th>
<tr>
<thead>
<tbody filter-list="search"ng-repeat="p in Pets">
<tr>
<td class="col-xs-6 col-sm-6 col-md-6 col-xl-6 merchant">
{{p.pet}}, {{p.place}} and {{p.points}}
</td>
<td class="col-xs-4 col-sm-4 col-md-4 col-xl-4 update">
<button ng-click="show()">Update</button>
<br>
<div ng-show="showing">
<input placeholder= "Pets" ng-model="Pets"/>
<br>
<input placeholder= "Places" ng-model="Places"/>
<br>
<input placeholder= "Points" ng-model="Points"/>
<br>
<button ng-click="Update(Pets, Places, Points)">Enter</button>
</div>
</td>
</tr>
</tbody>
</table>
show();功能
$scope.show = function() {
console.log("show")
$scope.showing = true;
}
答案 0 :(得分:3)
有时候,回归基础是最好的。由于我们知道ng-repeat
中的每次迭代都会创建一个新的范围,为了避免使用继承的show
函数,一个简单的showing != showing
应该可以工作(即使它{{1}默认情况下,它很好,因为这是一个假值,但你也可以随时初始化它)。
在此处查看:
undefined
&#13;
angular.module('app', [])
.controller('Ctrl', function($scope) {
$scope.Pets = [
{pet: 1, place: 1, points: 1},
{pet: 2, place: 2, points: 2},
{pet: 3, place: 3, points: 3}
];
})
&#13;
如果你不喜欢这种方法,并且想要使用一个常用功能(有理由你这样做,但我在你的例子中没有看到它们),你可以使用{ {1}}索引,然后执行以下操作:
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="Ctrl">
<table>
<thead>
<tr>
<th colspan="1" class="text-center">
Pets, Places and Points
</th>
<th colspan="1" class="text-center">
Update
</th>
<tr>
<thead>
<tbody ng-repeat="p in Pets">
<tr>
<td class="col-xs-6 col-sm-6 col-md-6 col-xl-6 merchant">
{{p.pet}}, {{p.place}} and {{p.points}}
</td>
<td class="col-xs-4 col-sm-4 col-md-4 col-xl-4 update">
<button ng-click="showing = !showing">Update</button>
<br>
<div ng-show="showing">
<input placeholder="Pets" ng-model="Pets" />
<br>
<input placeholder="Places" ng-model="Places" />
<br>
<input placeholder="Points" ng-model="Points" />
<br>
<button ng-click="Update(Pets, Places, Points)">Enter</button>
</div>
</td>
</tr>
</tbody>
</table>
</div>
只需像这样调用它:
ng-repeat
并像这样控制可见性:
$scope.show = function(i) {
console.log("showing " + i)
$scope.showing[i] = true;
}
在此处查看:
<button ng-click="show($index)">Update</button>
&#13;
<div ng-show="showing[$index]">
&#13;
