struts客户端验证，为什么生成的javascript都变成直接显示的文本了？而且生成的函数名不对阿。

Question

你先生成<script language="javascript">这个呀out.println("<script language=\"javascript\">");

Answer 1

注意转义，生成的script应该是没有问题，只要你的格式正确

Answer 2

你是说我在validator-rules.xml中写的不对吗，能不能说明白点

Answer 3

怎么感觉有点文不对题呢，
这句out.println("<script language=\"javascript\">");
是在哪里面的？？？

Answer 4

struts-config.xml---------------
<form-bean name="testValidatorForm" type="org.apache.struts.validator.DynaValidatorForm">testValidator.jsp----------------
<html:javascript formName="testValidatorForm"/><html:form action="/testValidator" method="post" onsubmit="return validateTestValidatorForm(this);"><bean:message key="test.name"/>
<html:text property="userName"/><html:errors property="userName"/><br/>PS: onsubmit="return ???这个的form名一定要和你struts-config.xml中的form名一样还有大小写也要注意，首字母都得大写"
在就是validator.xml中的属性名要和资源文件还有你的FormBean（或动态from）<form-bean name="testValidatorForm" type="org.apache.struts.validator.DynaValidatorForm">
      <form-property name="sex" type="java.lang.String" />
      <form-property name="userName" type="java.lang.String" />
      <form-property name="age" type="java.lang.String" />
    </form-bean>中一样，我估计是哪名字不一样或大小写问题吧！
