layui div 新增 加select 带输入模糊匹配录入

1:效果图

带删除功能,需要操作节点,节点  select 有id  新建时 id 命名后边加1

用了两个模版 一个是新增行模版,一个是带删除的模版,各负其责, 

1>模版

<script id="J_AddHtmlCreditor" type="text/html">
  {{each ModelDemo as value index}}
     {{if index==0}}
     <div class="layui-form-item" id="CreditorDiv" >
    {{else}}
    <div class="layui-form-item">
    {{/if}}
    <label class="layui-form-label"> {{if index==0}}选择框{{/if}}</label>
    <div class="layui-input-inline">
      <select name="Creditor{{index}}"  id="Creditor{{index}}" lay-search>
        <option value="" hidden>请选择</option>
        {{each value.CreditorList as va j}}
        {{if va==value.Creditor}}
        <option value="{{va}}" selected>{{va}}</option>
        {{else}}
        <option value="{{va}}">{{va}}</option>
        {{/if}}
        {{/each}}
      </select>
    </div>
    <div>
      <div class="layui-form-mid layui-word-aux">
        {{if index==0}}
        <button type="button" class="layui-btn" id="AddCreditor">
          <i class="layui-icon">&#xe608;</i> 新增
        </button>
        {{else}}
        <button type="button" class="layui-btn" onclick="javascript:delCreditorAction(this,'Creditor{{index}}')">
          <i class="layui-icon">&#xe640;</i> 删除
        </button>
        {{/if}}
      </div>
    </div>
  </div>
 {{/each}}
</script>
<script id="J_AddHtmlCreditorAdd" type="text/html">
  <div class="layui-form-item" >
    <label class="layui-form-label"></label>
    <div class="layui-input-inline" >
      <select name="{{ModelDemo.Creditor}}"   id="{{ModelDemo.Creditor}}" lay-search>
        <option value="" hidden>请选择</option>
        {{each ModelDemo.CreditorList as value index}}
        <option value="{{value}}" >{{value}}</option>
        {{/each}}
      </select>
    </div>
    <div class="layui-form-mid layui-word-aux">
      <button type="button" class="layui-btn"  onclick="javascript:delCreditorAction(this,'{{ModelDemo.Creditor}}')">
        <i class="layui-icon">&#xe640;</i> 删除
      </button>
    </div>
  </div>
</script>

2:模版需要挂在哪个位置 ,这个位置是同级的 div id  可以通过 先前设置好这个div id得到

3:后台写模版需要的数据.

4:js 获取到数据后赋值给模版, 然后把模版html 挂在提前设置好的id里边

这里新增时 怎么计算新增的id的,有个方法
