<body>

  <input type="text" id='input'>
  <p id="msg"></p>
  <button type="button" value="保存数据" onclick="saveStorage('input');">保存数据</button>
  <button type="button" value="显示数据" onclick="loadStorage('msg');">显示数据</button>
</body>
</html>

Js代码如下:

function saveStorage(x){
   var _this=document.getElementById(x);
   var _value=_this.value;
   localStorage.setItem('key',_value);
}
function loadStorage(y){
