Layui select 的动态添加

layui的select 若已经给了选项的数据，它还会动态生成另外一段代码 <dl class="layui-anim layui-anim-upbit"/>，若想自己添加动态的数据，则我们也需要添加 <dl class="layui-anim layui-anim-upbit"/>的选项数据，否则，select会失效。

添加两段选项的代码：

$("#GoodsModifyModel_GoodsCategorySel").next().children().eq(1)可找到动态生成的<dl>,用于添加<dd>

$("#GoodsModifyModel_GoodsCategorySel").next().children().eq(1).html(html1);//layui动态生成的<dl class="layui-anim layui-anim-upbit"/>的选项数据
$("#GoodsModifyModel_GoodsCategorySel").html(html2);//自己的select选项数据

前台 select代码：

<div class="layui-form-item">
       <label class="layui-form-label">类别</label>
       <div class="layui-input-inline">
             <select id="GoodsModifyModel_GoodsCategorySel" lay-verify="required" lay-search="">
            @*动态添加类别*@
            </select>
        </div>
</div>

layui select生成的完整代码：

<div class="layui-input-inline">
    <select id="GoodsAddModel_GoodsCategorySel">
        <option value="">直接选择或搜索选择</option>
        <option value="1">笔记本</option>
        <option value="2">台式电脑</option>
        <option value="3">鼠标</option>
        <option value="4">键盘</option>
    </select><div class="layui-unselect layui-form-select">
    <div class="layui-select-title">
        <input type="text" placeholder="直接选择或搜索选择" value="" readonly="" class="layui-input layui-unselect">
        <i class="layui-edge"></i>
    </div>
    <dl class="layui-anim layui-anim-upbit">
        <dd lay-value="" class="layui-select-tips">直接选择或搜索选择</dd>
        <dd lay-value="1" class="">笔记本</dd>
        <dd lay-value="2" class="">台式电脑</dd>
        <dd lay-value="3" class="">鼠标</dd>
        <dd lay-value="4" class="">键盘</dd>
    </dl>
    </div> 
 </div>

动态添加select 的代码如下所示:

@{
    Layout = null;
}
