<script type="text/javascript">var UserData = {        userData : null,        //name : location.hostname,        //this.name = "css88.com";        init:function(){            if (!UserData.userData) {                try {                    UserData.userData = document.createElement('INPUT');                    UserData.userData.type = "hidden";                    UserData.userData.style.display = "none";                    UserData.userData.addBehavior ("#default#userData");                    document.body.appendChild(UserData.userData);                    var expires = new Date();                    expires.setDate(expires.getDate()+365);                    UserData.userData.expires = expires.toUTCString();                } catch(e) {                    return false;                }            }            return true;        },        setItem : function(key, value) {if(UserData.init()){UserData.userData.load(UserData.name);UserData.userData.setAttribute(key, value);UserData.userData.save(UserData.name);            }},getItem : function(key) {if(UserData.init()){UserData.userData.load(UserData.name);return UserData.userData.getAttribute(key)}        },        remove : function(key) {            if(UserData.init()){UserData.userData.load(UserData.name);UserData.userData.removeAttribute(key);UserData.userData.save(UserData.name);            }        }    };</script>

例子测试：

<script type="text/javascript">var fnLoadInput = function(){alert(UserData.getItem("a"));alert(UserData.getItem("b"));alert(UserData.getItem("c"));};var fnSaveInput = function(){UserData.setItem("a","aaaaaaaa");UserData.setItem("b","bbbbbbbb");UserData.setItem("c","cccccccc");};</script></head><body><form id="oPersistForm"><input class="userData" type="text" id="oPersistInput" /><input type="button" value="load" onclick="fnLoadInput()" /><input type="button" value="save" onclick="fnSaveInput()" /></form></body>
