如何动态生成带角度的多级下拉菜单? [英] How can I dynamically generate a multi-level dropdown menu with angular?

问题描述

我使用引导程序制作了一个带有多个复选框的下拉菜单(参见 http://jsfiddle.net/rxdazn/ryzJb/3/).此下拉菜单将介绍在同一图表 + 多个选项(对数刻度等)上绘制多个图形(度量")的可能性.

I have made a dropdown menu with multiple checkboxes using bootstrap (see http://jsfiddle.net/rxdazn/ryzJb/3/ ). This dropdown menu will introduce the possibility to plot multiple graphs ("measures") on the same chart + multiple options (log scale etc.).

值列表(对应于度量")将存储在 json 对象中.目前，我只使用一个选择(用户只能绘制 1 个图表，没有图表类型或选项):

A list of values (corresponding to "measures") will be stored in a json object. For now, I am just using a single select (users can only plot 1 chart, there are no graph type nor options):

<select ng-model="measure" ng-options="facet.path as facet.name for facet in station.facet_groups[0].facets"></select>

我怎样才能最好地处理每个度量类型都具有相同子菜单的事实?
我应该更改我的 HTML 吗?我应该为 id 属性动态生成值吗?

How can I best handle the fact that each measure type will have the same submenu?
Should I change my HTML? Should I dynamically generate values for <input> id attributes ?

<!-- graph type -->
<li class="dropdown-submenu"> <a href="#">Graph type</a>

    <ul class="dropdown-menu">
        <li>
            <input type="checkbox" id="line" name="graph" value="line">
            <label for="line">line</label>
        </li>
        <li>
            <input type="checkbox" id="dot" name="graph" value="dot">
            <label for="dot">dot</label>
        </li>
    </ul>

推荐答案

由于 id 在页面上必须是唯一的，你肯定应该动态生成它们；另外，您可能还想在 input 元素中生成 name 属性，但这完全取决于您的用例.根据您的小提琴，我认为您可以像这样生成菜单:

Since an id must be unique on a page, you definitely should dynamically generate them; plus, you might also want to generate the name attribute in input element, but this is totally up to your use case. Based on you fiddle, I think you can generate your menu like this:

<ul id="menu">
    <li class="dropdown-submenu" ng-repeat="facet in facets"> <a href="#">{{facet.name}}</a>

        <ul class="dropdown-menu">
            <li>
                <input type="checkbox" id="{{facet.name}}-line" name="{{facet.name}}-graph" value="line">
                <label for="line">line</label>
            </li>
            <li>
                <input type="checkbox" id="{{facet.name}}-dot" name="{{facet.name}}-graph" value="dot">
                <label for="dot">dot</label>
            </li>
        </ul>
    </li>
</ul>

我尝试根据 facet.name 生成 id 和 name，您可能需要更改它以满足您的需要.

I try to generate the id and name based on facet.name, you may want to change it to suit you needs.
