js的代码function savestorage(id){
var data = document.getelementbyid(id).value; var time = new date().gettime();
localstorage.setitem(time,data);
loadstorage('msg');
}function loadstorage(id){
var result = "<table border = '1'>"; for(var i = 0;i < loadstorage.length;i++){ var key = localstorage.key(i); var value = localstorage.getitem(key); var date = new date();
date.settime(key);
result += "<tr><td>"+value+"</td><td>"+date+"</td></tr>";
}
result += "</table>"; var target = document.getelementbyid(id);
target.innerhtml = result;
}function clearstorage(){
localstorage.clear();
loadstorage('msg');
}
