1 页面如下:

<%@ page contentType="text/html;charset=UTF-8" isErrorPage="true"%>

<html>

<head>

<title>

表单的测试

</title>

function getsubmit()

{

var username="username="+document.getElementById("username").value;//第一行的元素

var sexvalue = document.getElementsByName("usersex");

var turesexvalue;//因为sexvalue有多个值，所以需要更多的判断。

for(i=0;i<sexvalue.length;i++)

{

if(sexvalue[i].checked)//判断哪个值被选中

{

turesexvalue=sexvalue[i].value;//获得被选中的值

}

var usersex= "&usersex="+turesexvalue;//第二行的元素

var hobbyvalue=document.getElementsByName("hobby");

var checkhobby="";

for(i=0;i<hobbyvalue.length;i++)

{

if(hobbyvalue[i].checked)//判断哪个值被选中

{

checkhobby=checkhobby+hobbyvalue[i].value+"|";//获得被选中的值，并累加

}

var hobby="&hobby="+checkhobby;//第三行的元素

var nation = "&nation="+document.getElementById("nation").value;//第四行的元素

var descript="&descript="+document.getElementById("descript").value;

//把要提交的控件用字符串的形式拼在提交的方法

var urls = "getgo?"+username+usersex+hobby+nation+descript;

alert(urls);

window.location=urls;

}

</script>
