使用angularJS在html中添加/删除框

Question

我想使用angularJS在HTML中创建/使用像this这样的添加删除框，其中左侧有一些对象的列表，您可以选择将它们放在下面列出的标题下的对象。对。知道我们称之为这样的表/列表，我可以创建/找到它们吗？

Answer 1

我不知道称它的准确标题是什么：）

但我试图实施一个＆＃39;添加/删除框＆＃39;用 AngularJS 来实现您想要的概念！

主要部分由三部分组成：

1. 左栏将会添加
2. 中间部分，其中包含按钮
3. 正确的部分将会删除

以下代码适用上述部分：

<div class="box leftBox">
    <div>
        <div id="{{left.name}}" ng-click="clicked($event, 0)" data-ng-repeat="left in lefts">{{left.name}}</div>
    </div>
</div>

<div class="box button_holder">
    <button ng-click="add()" class="button button-blue">ADD ></button>
    <button ng-click="remove()" class="button button-red">< REMOVE</button>
    <button ng-click="addAll()" class="button button-blue button-dark">ADD ALL >></button>
    <button ng-click="removeAll()" class="button button-red button-dark"><< REMOVE ALL</button>
    <button ng-click="deleteChoice()" class="button delete">X</button>
</div>

<div class="box rightBox">
    <div>
        <div ng-click="clicked($event, 1)" data-ng-repeat="right in rights">{{right.name}}</div>
    </div>
</div>

通过使用包含data-ng-repeat的angularjs指令，您可以控制添加或删除

的过程

  

here是已实施的概述。
