AngularJS复选框NG-重复和选择的对象？ [英] AngularJS checkbox ng-repeat and selected objects?

问题描述

我想痛苦少做以适当的方式，但我无法弄清楚如何处理NG-模型并将其绑定到选中的列表等，此外我需要填充的稍晚时间列表，保持选定的对象了。

 类别= [{名：运动，ID：50d5ad}，{名：常规，ID：678ffr} ]    ＆LT;跨度NG重复=类别中的类别＆GT;
      ＆LT;标签类=复选框为={{category.id}}＆GT;
        ＆LT;输入类型=复选框VALUE ={{category.id}}NG模型=?? NG-点击=?? NAME =组ID ={{category.id}}/＆GT;
        {{category.name}}
      ＆LT; /标签＆gt;
    ＆LT; / SPAN＆GT;
 

我有每个列表中填充，因为它将从一个服务器拉出时间重写的类别。

所以我想我需要有数组，第二个将举行选定的对象？

如果我是正确的，我怎么preSELECT复选框？

我是否需要NG-点击为了调用自定义函数存储另一个阵列中选定的对象？

我是否需要NG-模型复选框，什么？

什么是正确的路痛苦少？

解决方案

  

我每次列表中填充覆盖类
  因为这将是拉出形式的服务器。所以我quess我需要有
  阵列，第二个将举行选定的对象？

是的，因为它是一个列表，您可以/应该使用数组。有关所选项目/对象的信息应存放在你的范围模型（下面的例子）。

  

如果我是正确的，我怎么preselected复选框？

保存ID在模型上选定的选项/复选框的，让 NG-模型做休息。

  

我是否需要为了调用自定义函数NG-点击存储选定
  其他阵列中的对象？

没有，你不需要它， NG-模型就足够了。

  

我是否需要在复选框NG-模式？干嘛？

是的，你需要它。在 NG-模型负责存储你的模型所选的选项及其制造（'pre - '）。选择自动

I am trying to do it in proper way with less pain, but i can't figure out how to deal with ng-model and binding it to the selected list etc and moreover i need to populate that list in later time and keep selected objects in it.

categories = [ { "name": "Sport", "id": "50d5ad" } , {"name": "General", "id": "678ffr" } ]

    <span ng-repeat="category in categories">
      <label class="checkbox" for="{{category.id}}">
        <input type="checkbox" value="{{category.id}}" ng-model="??" ng-click="??" name="group" id="{{category.id}}" />
        {{category.name}}
      </label>
    </span>

I have to override the categories each time the list is populated since it will be pulled out from a server.

So I guess I need to have arrays and the second one will hold the selected objects?

If I am right, how do I preselect checkboxes?

Do I need ng-click in order call custom function to store the selected object in the other array?

Do I need ng-model in checkbox And what for?

What is the proper-way with less pain?

Yes, since it is a list you can/should use arrays. The information about the selected items/objects should be stored on your scope model (example below).

If I am right, how do I preselected checkboxes?

Save the ID's of the selected options/checkboxes on your model and let the ng-model do the rest.

Do I need ng-click in order call custom function to store the selected object in the other array?

No, you don't need it, ng-model is enough.

Do i need ng-model in check box? And what for?

Yes, you need it. The ng-model is responsible for storing the selected options on your model and for making the ('pre-')selection automatic.
