HTML表单提交空值

这是我的JSP页面：HTML表单提交空值

<%@ page language="java" contentType="text/html; charset=utf-8" 
pageEncoding="ISO-8859-1"%> 
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> 
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 
    <html> 
    <head> 
    <meta http-equiv="Content-Type" 
    content="text/html;charset=utf-8" /> 
    <title>Entry Form</title> 
    <link href="../css_res/style.css" rel="stylesheet" type="text/css" media="screen" /> 
    </head> 
    <body> 
    <div id="MongoFORM"> 
     <h1>Add New Entries To Database</h1> 
     <form action='../restful-services/errorops/PUSH2DB' onsubmit='this.submit();this.reset();return false;' method="post"> 
      <fieldset> 
       <label for="ErrorName">Error Name:</label> 
       <input required type="text" name="ErName" id="ErrorName" placeholder="Enter the Error Name" /> 

       <label for="ErrorCause">Error Cause:</label> 
       <input required type="text" name="ErCause" id="ErrorCause" placeholder="Enter generic cause" /> 

       <label for="ErrorResolution">Error Resolution:</label> 
       <input required type="text" name="ErResolution" id="ErrorResolution" placeholder="Enter generic resolution" /> 

       <label for="TechnicalDat">Technical Data:</label> 
       <input required type="text" name="TlDat" id="TechnicalDat" placeholder="Enter error code base info (JSON)" /> 
       <br> 
       <br> 
       <input type="submit" class="large default" value="POST TO DB!" /> 
      </fieldset> 
     </form> 
    </div> 

    </body> 
    </html>

我的问题是，当我在POST点击到数据库！按钮，空值被提交。然而，当onsubmit ='this.submit（）; this.reset（）; return false;'选项已删除。任何人都可以请指导我解决问题吗？

onsubmit()在表单提交之前运行，所以表单在提交前重置
