Question

我有一张这样的地图

company = [no:[01, 02], name:[abc, def]]

如何在html上的选择框中显示这些信息？这意味着每个选项都有值：

option1: 01: abc
option2: 02: def

我试过

<select>
   <g:each in="${grailsApplication.config.Companies}" var="company">
      <option>${company}</option>
   </g:each>
</select>

但它只显示选项1：否：[01,02] 选项2：名称：[abc，def]] 请帮忙，谢谢！

注意：$ {grailsApplication.config.Companies} =上面的阵列公司

Answer 1

尝试像这样实现它

<select>
   <g:each in="${grailsApplication.config.Companies[no]}" var="company" status="index">
     <option value="${grailsApplication.config.Companies['no'][index]}">${grailsApplication.config.Companies['name'][index]}</option>
   </g:each>
</select>

从映射到html选择框的groovy解析值
