js携带参数页面跳转
方法一：跳转路径携带参数
第一个页面：
location.replace("user.html?username=" + username + "&userPsd=" + userPsd);
跳转后的页面
//获取路径携带的参数 var username =
(location.search).substring(((location.search).indexOf("=") + 1),
(location.search).indexOf("&")); //传递一个参数时，用下面的获取 var password =
(location.search).substring(((location.search).lastIndexOf("=") + 1),
(location.search).length);
缺点：跳转后的路径后面携带参数和值
.../html/user.html?username=aaa&userPwd=111
方法二： sessionStorage传递
sessionStorage属性允许在浏览器中存储 key/value 对的数据，但sessionStorage
用于临时保存同一窗口(或标签页)的数据，在关闭窗口或标签页之后将会删除这些数据。
页面一：
//获取输入框的值 var username = document.getElementById("username").value; var
userPsd = document.getElementById("password").value; //跳转路径
location.replace("user.html");
//设置sessionStorage：-----------主要代码-------------------------------
window.sessionStorage.setItem('username', username);
window.sessionStorage.setItem('password', userPsd);
可以在浏览器中查看：运行后浏览器右键-检查
页面二：
//在跳转后页面，通过getItem方法来获取 var username =
window.sessionStorage.getItem('username'); var password =
window.sessionStorage.getItem('password');
具体数据可根据实际要求更改
