我只是尝试在带有 struts 提供的标签的 jsp 页面中包含一个文本框。但它表现得很典型。
在职的<html:text property="name" value=""></html:text>
不工作<html:text property="name"></html:text>所以，没有属性(property)'value' ，它不工作。
请帮帮我。
笔记:
使用 tomcat 6.0
bean，逻辑运行良好，在 html 中，它们中的大多数都在运行。 radio、textarea、text 是一些导致问题的原因。

最佳答案
<html:text>标签应该包含在 <html:form> 内标签，它定义了 Action ，从而定义了 <html:text> 的 ActionForm 实例。得到它的值(value)。
关于struts-1 - Struts html 标签不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/14083862/
