如何访问 struts 标签中的迭代器变量?-尊龙凯时

问题描述

我正在遍历一个列表并希望访问该值以创建一个文本输入字段.不幸的是，我无法访问标签内的循环变量

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 tag

这是我尝试过的:

被正确评估并显示循环变量.但是中的 #tag 永远不会被评估.

the is evaluated correctly and shows the loop variable. but the #tag in the is never evaluated.

我也尝试用代替 #tag 没有成功.

i also tried to put instead of #tag without success.

推荐答案

使用标签的key属性代替三个name,value,标签.至于你已经定义的其中两个，你可以改变

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

该值由 name 属性检索.您应该为 name 属性中评估的名称提供一个 getter.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.
