两个html页面之间怎么传递参数值
展开全部
使用Cookie传递参数 ,a页面保存Cookie,b页面读取,代码如下:
a页面
<html>
<head>
<title>a</title>
<style type="text/css">
* {margin:0}
body {text-align:center;min-width:760px}
div {padding:3px 3px 3px 3px}
#main {width:720px;margin:0 auto;text-align:left;margin-top:30px}
#main div span {width:50px}
</style>
<script type="text/javascript">
/***
* @param {string} cookieName Cookie名称
* @param {string} cookieValue Cookie值
* @param {number} nDays Cookie过期天数
*/
function SetCookie(cookieName,cookieValue,nDays) {
/*当前日期*/
var today = new Date();
/*Cookie过期时间*/
var expire = new Date();
/*如果未设置nDays参数或者nDays为0,取默认值1*/
if(nDays == null || nDays == 0) nDays = 1;
/*计算Cookie过期时间*/
expire.setTime(today.getTime() + 3600000 * 24 * nDays);
/*设置Cookie值*/
document.cookie = cookieName + "=" + escape(cookieValue)
+ ";expires=" + expire.toGMTString();
}
function login() {
var username = $("user").value;
var password = $("pass").value;
/*是否选中7天内无需登录*/
var save = $("save").checked;
if(username=="abc" && password=="abc") {
if(save) SetCookie("username",username,7);
else SetCookie("username",username,1);
/*跳转到ex8.html页面*/
document.location = "b.htm";
} else {
alert("用户名或密码错误!");
}
}
function $(id) {
return document.getElementById(id);
}
</script>
</head>
<body>
<div id="main">
<div><span>用户名:</span><input type="text" id="user" /></div>
<div><span>密码:</span><input type="password" id="pass" /></div>
<div>
<input type="checkbox" id="save" />
7天内无需登录
<input type="button" onclick="login()" value="登录" />
</div>
</div>
</body>
</html>
b页面
<html>
<head>
<title>b</title>
<script type="text/javascript">
/***
*读取指定的Cookie值
*@param {string} cookieName Cookie名称
*/
function ReadCookie(cookieName) {
var theCookie = "" + document.cookie;
var ind = theCookie.indexOf(cookieName);
if(ind==-1 || cookieName=="") return "";
var ind1 = theCookie.indexOf(';',ind);
if(ind1==-1) ind1 = theCookie.length;
/*读取Cookie值*/
return unescape(theCookie.substring(ind+cookieName.length+1,ind1));
}
function $(id) {
return document.getElementById(id);
}
function init() {
var username = ReadCookie("username");
if(username && username.length>0) {
$("msg").innerHTML = "<h1>欢迎光临," + username + "!</h1>";
} else {
$("msg").innerHTML = "<a href='a.htm'>请登录</a>";
}
}
</script>
</head>
<body onload="init()">
<div id="msg"></div>
</body>
</html>
效果如下:

假设有a页面 a.html b页面 b.html
a页面向b页面传递参数
a.html
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>page a</title>
<script>
var params = function(args){
var p = [];
for(var n in args)
p.push( n + '=' + args[n]);
return encodeURI('?' + p.join('&'));
};
window.onload = function(){
document.getElementById('send').onclick = function(){
var data = {
name:'参数1',
value:'1'
};
//向b页面传递参数 name,value
location.href = 'b.html' + params(data);
};
};
</script>
</head>
<body>
<button id="send">send</button>
</body>
</html>
b.html
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>page a</title>
<script>
var args = function(params){
var a = {};
params = params || location.search;
if(!params) return {};
params = decodeURI(params);
params.replace(/(?:^\?|&)([^=&]+)(?:\=)([^=&]+)(?=&|$)/g,function(m,k,v){ a[k] = v; });
return a;
};
window.onload = function(){
var argsFromPageA = args();
// 打印a页面传递来的参数
console.log(argsFromPageA);
};
</script>
</head>
<body>
</body>
</html>
