如何使用java脚本将button的值获取到其他jsp中



我必须在jsp的其他页面上获得按钮值,并根据条件执行<div>标记,我的index.jsp代码是这个

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jstl/fmt" %>
<%@ taglib prefix="sql" uri="http://java.sun.com/jstl/sql" %>
<%@ taglib prefix="x" uri="http://java.sun.com/jstl/xml" %>
<html>
<head>
<script type="text/javascript">
function popuponclick()
{
my_window = window.open("file.jsp",
"mywindow","status=1,width=350,height=150");
}

</script>
</head>
<table>
<tr>
<td><button type="button" onclick="popuponclick()" value="1" name="name">GetAllEmployeeByID</button></td>
</tr>
<tr>
<td><button type="button" onclick="popuponclick()" value="2" name="name">GetEmployeeByName</button></td>
</tr>
</table>
</body>
</html>

我的second.jsp就是这个

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"%>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jstl/fmt"%>
<%@ taglib prefix="sql" uri="http://java.sun.com/jstl/sql"%>
<%@ taglib prefix="x" uri="http://java.sun.com/jstl/xml"%>
<%@page import="com.nousinfo.tutorial.employee.service.model.bo.EmployeeBO" %>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
<script>
function myfuntion(String name)
{ 
location.
document.getElementById("div1");
}
</script>
</head>
<body>
<form action="/EmployeeWeb/GetEmployee">
<div id="div1" style="display: block;">
<table>
<tr>
<td width="29">Find_Employee_By_Name:</td>
<td><input type="text" name="findbyname" /></td>

</tr>
<tr>
<td><input type="submit" name="submit" value="find"></td>
</tr>
</table>
</div>
<div id="div2" style="display: none;">
<table>
<tr>
<td width="29">Find_Employee_By_Name:</td>
<td><input type="text" name="findbyname" /></td>
</tr>
<tr>
<td><input type="submit" name="submit" value="find"></td>
</tr>
</table>
</div> 
</form>
<button onclick="myfunction()"></button>
</body>
</html>

我将如何在第二个jsp中获得按钮值,以便根据条件运行<div>标记部分

在index.jsp页面中试试这个:

function popuponclick()
{
var my_window = window.open("file.jsp", "mywindow","status=1,width=350,height=150");
// Gets the two divs
var div1 = my_window.document.getElementById('div1');
var div2 = my_window.document.getElementById('div2');
// Hides the two divs
div1.style.display = 'none';
div2.style.display = 'none';
// Check what the value of the button pressed and displays the correct div
if(this.value = '1')
div1.style.display = 'block';
else
div2.style.display = 'block';
}

如果我答对了你的问题,试试这样的方法。您需要在按钮中添加一些ID,以便轻松选择它们。

用按钮id替换(用斜杠)\button id here\,并将some value替换为要匹配的值(例如-2)。

if(document.getElementById('\button id\').value=\some value){

}其他{

}

顺便说一句,在第二个jsp中,您得到了这样的构造:位置.dococument.getElementById

在"location"对象中没有"document"属性,请在不使用"location"的情况下使用它。
