  • HTML5 LocalStorage 本地存储

    1.前言

           HTML5 storage提供了一种方式让网站能够把信息存储到你本地的计算机上，并再以后需要的时候进行获取。这个概念和cookie相似，区别是它是为了更大容量存储设计的。Cookie的大小是受限的，并且每次你请求一个新的页面的时候cookie都会被发送过去。HTML5的storage是存储在你的计算机上，网站在页面加载完毕后可以通过Javascript来获取这些数据。首先自然是检测浏览器是否支持本地存储。在HTML5中，本地存储是一个window的属性，包括localStorage和sessionStorage，从名字应该可以很清楚的辨认二者的区别，前者是一直存在本地的，后者只是伴随着session，窗口一旦关闭就没了。二者用法完全相同，这里以localStorage为例。

    if(window.localStorage){
     alert('支持localStorage');
    }else{
     alert('不支持localStorage');
    }

    2.基本用法

         存储数据的方法就是直接给window.localStorage添加一个属性，例如：window.localStorage.a 或者 window.localStorage["a"]。它的读取、写、删除操作方法很简单，是以键值对的方式存在的，如下：

    localStorage.name = "kobi";//设置name为"kobi"
    localStorage["name"] = "koko";//设置name为"koko"，覆盖上面的值
    localStorage.setItem("age","18");//设置age为"18"
    var a1 = localStorage["name"];//获取name的值
    var a2 = localStorage.age;//获取age的值
    var b = localStorage.getItem("name");//获取name的值
    localStorage.removeItem("c");//清除c的值

     这里最推荐使用的自然是getItem()和setItem()，清除键值对使用removeItem()。如果希望一次性清除所有的键值对，可以使用clear()。另外，HTML5还提供了一个key()方法，可以在不知道有哪些键值的时候使用，如下：

    var storage = window.localStorage;
    function showStorage(){
     for(var i=0;i<storage.length;i++){
      //key(i)获得相应的键，再用getItem()方法获得对应的值
      document.write(storage.key(i)+ " : " + storage.getItem(storage.key(i)) + "<br>");
     }
    }

     3.业务需求

         表单实时保存数据，下次打开则提示是否继续编辑。图片等控件不支持，只支持简单的控件。【防止突然断电或浏览器崩溃时，下次打开还可以继续编辑并保存】。这样自然而然就想到了HTML5的本地存储功能。既然js写的烂，写的差，就当练手了。

    其实这些数据的保存很简单，无非就是一些简单的标签数据的保存。先来一个最简单的js版本。

     Grid控件其实就是一个div，公司的一些页面表单都是动态生成的，表单上面的控件也是动态生成的，所有很多东西都是自己手写的。下面是Grid控件的结构。

    <div class="FM000103-SBCLBJ form-table  "> 
   <input data-datagrid="true" data-formid="FM000034" name="SBCLBJ" type="hidden" /> 
   <input data-param="init" type="hidden" value="{&quot;ID&quot;:&quot;$[ID]&quot;,&quot;IID&quot;:&quot;$(autoid)&quot;}" /> 
   <input data-param="initsame" type="hidden" value="[]" /> 
   <div class="form-table-header"> 
    <div style="48px;">
     编辑
    </div> 
    <div style="50px;">
     序号
    </div> 
    <div style="60px;">
     是否上传
    </div> 
    <div style="380px;">
     申报材料内容
    </div> 
    <div style="80px;">
     备注
    </div> 
   </div> 
   <div class="form-table-body"> 
    <table class="table-hover"> 
     <colgroup span="6"> 
      <col width="48" /> 
      <col width="50" data-type="RowNumber" /> 
      <col width="0" data-type="Label" data-index="ID" class="hidden" /> 
      <col width="0" data-type="Label" data-index="IID" class="hidden" /> 
      <col width="60" data-type="CheckBox" data-index="CDZL" /> 
      <col width="380" data-type="TextArea" data-index="ATDESC" /> 
      <col width="80" data-type="TextArea" data-index="BZ" /> 
     </colgroup> 
     <tbody>
      <tr> 
       <td class="form-table-edit"><span class="glyphicon glyphicon-edit" aria-hidden="true"></span></td> 
       <td>1</td> 
       <td class="hidden">BM00001141</td> 
       <td class="hidden">4643</td> 
       <td><input type="checkbox" value="1" checked="checked" /></td> 
       <td>11111</td> 
       <td>2222</td> 
      </tr> 
      <tr> 
       <td class="form-table-edit"><span class="glyphicon glyphicon-edit" aria-hidden="true"></span></td> 
       <td>2</td> 
       <td class="hidden">BM00001141</td> 
       <td class="hidden">4644</td> 
       <td><input type="checkbox" value="0" /></td> 
       <td>87789789789798789</td> 
       <td>333</td> 
      </tr> 
     </tbody>
    </table> 
   </div> 
   <div class="form-table-footer"> 
    <button type="button" class="btn add-row">新增</button> 
    <button type="button" class="btn del-row">删除</button> 
   </div> 
  </div>
