尝试以下代码。不要忘记添加jQuery库：<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>复制并粘贴以下代码，然后运行：<%@page import="PresentationPkg.TestCls"%><%@page contentType="text/html" pageEncoding="UTF-8"%><!DOCTYPE html><html><head><script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>JSP页面</title></head><body><%String newTestResultCode = TestCls.getMaxTestResultID();%><form action="ex.jsp"><input type="text" id="resultCode" name="resultCode"><input id="myButton" type="button" name="viewValue" value="提交查看" /></form><script type="text/javascript">$(document).ready(function() {$('#myButton').click(function (){$("#resultCode").val("<%=newTestResultCode%>");});});</script></body></html>您还可以在您的项目中下载jQuery库并使用它。这个JavaScript函数将会将您的变量数据设置到输入框中。
英文:
Try Below Code. Do not forget to add jquery js
>< script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></ script>
Copy paste below code and run it.
<%@page import="PresentationPkg.TestCls"%><%@page contentType="text/html" pageEncoding="UTF-8"%><!DOCTYPE html><html><head><script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>JSP Page</title></head><body><%String newTestResultCode = TestCls.getMaxTestResultID();%><form action="ex.jsp"><input type="text" id="resultCode" name="resultCode"><input id="myButton" type="button" name="viewValue" value="Submit View" /></form><script type="text/javascript">$(document).ready(function() {$('#myButton').click(function (){$("#resultCode").val("<%=newTestResultCode%>");});});</script></body></html>
You can also download jquery js in your project and use it. The js function will set your variable data into input box.

这应该可以运行：
<input type="text" id="resultCode" name="resultCode" value=<%=newTestResultCode%>>
英文:
This should work:
<input type="text" id="resultCode" name="resultCode" value=<%=newTestResultCode%>>
