g：每个在一个表格中 [英] g:each in a table

问题描述

你好我正在使用groovy& Grails的。试图在表中循环。每次开始时都会出现错误

 < table class ='display'> 
< tr> 
< th> ID< / th> 
< th> NAME< / th> 
 IATA< / th> 
 STATE< / th> 
< th> COUNTRY< / th> 
 
< / tr> 
 
< g：每个in =$ {airportsInstanceList}var =book> 
< tr> 
< td> $ {airports.id}< / td> 
< td> $ {fieldValue（bean：airports，field：name）}< / td> 
< td> $ {airports.iata}< / td> 
< td> $ {airports.state}< / td> 
< td> $ {airports.country}< / td> 
<！ - < td>< g：link action =showid =$ {airports.id}>详情< / g：link>< / td>  - > ; 
 
< / tr> 
< / g：每个> 
< / table> 
  

解决方案

var 属性是迭代变量的名称。将它从 book 更改为 airports 。更改机场到机场也会更有意义，不过这只是一个风格问题。

Hi i'm using groovy & grails. trying to loop in a table. Getting error at start of g each

<table class='display'>
  <tr>
    <th>ID</th>
    <th>NAME</th>
    <th>IATA</th>
    <th>STATE</th>
    <th>COUNTRY</th>

  </tr>

  <g:each in="${airportsInstanceList}" var="book">
    <tr>
      <td>${airports.id}</td>
      <td>${fieldValue(bean: airports, field: "name")}</td>
      <td>${airports.iata}</td>
      <td>${airports.state}</td>
      <td>${airports.country}</td>
<!--      <td><g:link action="show" id="${airports.id}">details</g:link></td>-->

    </tr>
  </g:each>
</table>

解决方案

The var attribute is the name of the iteration variable. Change that from book to airports. Changing airports to airport would make more sense, too, although that's just an issue of style.
