<form id="myForm">
Firstname: <input id="fname" type="text" value="Mickey" />
Lastname: <input id="lname" type="text" value="Mouse" />
<input id="sub" type="button" value="Submit" />

<p>Get the value of all the elements in the form:<br />
<script type="text/javascript">
var x=document.getElementById("myForm");
var len = x["length"];

alert(typeof(window.localStorage));

localStorage.a = 3;//设置a为"3"
localStorage["a"] = "sfsf";//设置a为"sfsf"，覆盖上面的值
localStorage.setItem("b","isaac");//设置b为"isaac"
var a1 = localStorage["a"];//获取a的值
var a2 = localStorage.a;//获取a的值
var b = localStorage.getItem("b");//获取b的值
localStorage.removeItem("c");//清除c的值

alert(window.localStorage.getItem("b"))
for (var i=0;i<x.length;)
  {

      x.removeChild(x.elements[i])
  }
