如何访问struts标签中的迭代器变量? [英] How to access iterator variable in struts tag?

问题描述

我正在遍历列表，并希望访问该值以创建文本输入字段.不幸的是，我无法访问<s:textfield>标记内的循环变量

I'm looping over a list and want to access the value to create a text input field. Unfortunatley I'm failing to access the loop variable inside the <s:textfield> tag

这是我尝试过的:

  <s:iterator var="tag" value="searchTagList">
    <s:property value="#tag"/>
    <s:textfield key="searchResults.#tag" name="#tag" value="#tag" />
  </s:iterator>

<s:property value="#tag"/>被正确评估并显示循环变量.但是，永远不会评估<s:textfield>中的#tag.我还尝试将<s:property value="#tag"/>代替#tag而不成功.

The <s:property value="#tag"/> is evaluated correctly and shows the loop variable. But the #tag in the <s:textfield> is never evaluated. I also tried to put <s:property value="#tag"/> instead of #tag without success.

推荐答案

使用了标签的key属性，而不是三个name，value，label.到目前为止，您已经定义了其中两个，就可以更改

The tag's key attribute used instead of three ones name,value,label. As far as two of them you have already defined, you can change

<s:textfield label="%{getText('searchResults.'+#tag)}" name="%{#tag}" />

该值由name属性检索.您应该为在name属性中评估的名称提供一个吸气剂.请注意，如果您的操作扩展了ActionSupport，则getText()可用.而且，您必须在名称标签中强制进行名称评估.

The value is retrieved by the name attribute. You should provide a getter for the name evaluated in the name attribute. Note, getText() is available if your action extends ActionSupport. And you have to force name evaluation in the name tag.
