javascript - 单击时将值保存在 LocalStorage 中？

Question

每次用户单击向上或向下时都尝试将此值保存到本地存储？？？

<script>
   var Clicks = 800;
   function UpClick() {
      Clicks = Clicks + 25;
      document.getElementById('CountedClicks').innerHTML = Clicks + '';
      if (Clicks > 950) {
         Clicks = 950;
      }
   }
   function DownClick() {
      Clicks = Clicks - 25;
      document.getElementById('CountedClicks').innerHTML = Clicks + '';
      if (Clicks <= 0) {
        Clicks = 25;
      }
   }
</script>

<span id="CountedClicks">800</span>
  <input type="image" src="http://findicons.com/files/icons/2332/super_m/64/navigation_up_button.png" name="1462_EXPOSURE_TI_UP" value="1462_EXPOSURE_TI_UP_BUTTON_WAS_CLICKED" onclick="UpClick()" />

  <input type="image" src="http://findicons.com/files/icons/2332/super_mono/64/navigation_down_button.png" name="1462_EXPOSURE_TI_DOWN" value="" onclick="DownClick()" />

将其制作成jsfiddle:http://jsfiddle.net/JRxcr/6/

似乎无法掌握 getItem 或 setItem 的窍门，已经阅读了数小时的 Material ，只是没有得到它希望有人可以提供帮助

谢谢...

这些是我在做实验时想到的。

window.localStorage.setItem('点击次数', 20);

window.localStorage.getItem('点击次数');

所以一切都会像......

<script>
    var Clicks = 800;
function UpClick() {
    Clicks = Clicks + 25;
    document.getElementById('CountedClicks').innerHTML = Clicks + '';
    document
    if (Clicks > 950) {
        Clicks = 950;
    }
}
function DownClick() {
    Clicks = Clicks - 25;
    document.getElementById('CountedClicks').innerHTML = Clicks + '';
    if (Clicks <= 0) {
        Clicks = 25;
    }
}

function SaveClicks(){
    window.localStorage.setItem('clicks',Clicks);
}

function GetClicks(){
    return window.localStorage.getItem('clicks');
}

</script>

<span id="CountedClicks">800</span>
<input type=
      "image" src="http://findicons.com/files/icons/2332/super_mono/64/navigation_up_button.png" name="1462_EXPOSURE_TI_UP" value=
      "1462_EXPOSURE_TI_UP_BUTTON_WAS_CLICKED" onclick="UpClick();SaveClicks();" />

<input type="image" src="http://findicons.com/files/icons/2332/super_mono/64/navigation_down_button.png" name="1462_EXPOSURE_TI_DOWN" value="" onclick="DownClick();SaveClicks();" />
