手持设备本地存储

本地存储分localStorage和sessionStorage localStorage保存在用户设备中,不随关闭浏览器而消失 <!DOCTYPE html> <html> <head> <title>Untitled Page</title> <script type="text/jscript"> function a() { // 判断浏览器是否允许localStorage if (window.localStorage) { alert("localStorage"); } else { alert("no localStorage"); } // 判断浏览器是否允许sessionStorage if (window.sessionStorage) { alert("sessionStorage"); } else { alert("no sessionStorage"); } var userData = { name: "yxu1", sex: "male" }; localStorage.setItem("userData",JSON.stringify(userData)); var newUserData=JSON.parse(localStorage.getItem("userData")); alert(newUserData.name); userData.name = "yxu2"; localStorage.setItem("userData", JSON.stringify(userData)); alert(userData.name); // 删除 localStorage.removeItem("userData"); // 清空 localStorage.clear(); alert("close"); } </script> </head> <body> <input id="Button1" type="button" value="button" onclick="a();" /> </body> </html>
