    alert("网络断开了");
});




</script>
</body>

13.全屏接口的使用

<body>
<div>
    <img src="images/1.png" alt="">
    <input type="button" id="full" value="全屏">
    <input type="button" id="cancelFull" value="退出全屏">
    <input type="button" id="isFull" value="是否全屏">
</div>


<script>
    /*

    * 2.cancelFullScreen()  : 退出全屏显示    ||不同的浏览器要加不同的前缀 chrome:webkit  firefox:moz    ie:ms  opera:o
    *                                           退出全屏只能在docment 下操作.
    * 3.fullScreenElement : 是不是全屏状态?
    *
    * */

  window.onload=function(){
            var div=document.querySelector("div");
            /*添加按钮的点击事件*/
            document.querySelector("#full").onclick=function(){  //1.全屏按钮

               // div.mozRequestFullScreen();
            }


      document.querySelector("#cancelFull").onclick=function(){  //2.退出全屏按钮
          document.webkitCancelFullScreen();
      }

      document.querySelector("#isFull").onclick=function(){  //3.是否是全屏
          if ( document.fullScreenElement){
              alert(true);
          }else{
              alert(false);
          }

      }

  }



</script>

</body>

14.fileReader文件读取

<body>

<!--<img src="images/1.png" alt="">-->

<!--需求案例:即时预览-->
<form action="">
    文件:
    <input type="file" name="myFile" id="myFile" onchange="getFileContent()"><br>
    <input type="submit" value="提交">
</form>
<img src="" alt="即时浏览的图片">

<script>
    /*FileReader: 读取文件内容
    * 1.readerAsText() : txt文本,返回字符串 默认UTF-8
    * 2.readerAsBinaryString() : 读取任意类型文件,返回二进制字符串.*此方法一般用于存储文件内容*.
    * 3.readerAsDataURL() : 读取一段文件以data开头的字符串.本质就是将文本嵌入到文档的方案. abort() : 中断读取
    *
    * */

    function getFileContent(){
       // alert("123");
        // 1.创建文件读取对象
        var reader=new FileReader();
        //2.读取文件,获取DataURL
            //2.1:此方法没有返回值.
            //2.2:需要传递一个参数.
var file=document.querySelector("#myFile").files;
    reader.readAsDataURL(file[0]);
   // alert(reader.result);

    /*onabort : 中断时触发
    * onerror : 读取错误时触发

        alert(reader.result);
        document.querySelector("img").src=reader.result;

     }
    }
</script>
</body>

15.拖拽接口(上)

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        div{
            width: 200px;
            height: 200px;
            border: 1px solid #ccc;
            float: left;
            margin-right: 15px;
        }
    </style>
</head>
<body>



<div id="div1" class="div1">
    <p id="pe" draggable="true">试试把我拖拽过去</p>
</div>

<div id="div2" class="div2">

</div>





<script>
   //1.在H5中给对象元素添加draggable="true".才可实现拖拽.图片和超链接时默认可以拖拽的

    //2.拖拽事件
        //2.1应用于被拖拽元素的事件
 /*   ondrag : 拖拽过程中调用
     ondragstart : 拖拽开始调用.
        ondragleave : 鼠标离开拖拽元素时调用
        ondragend : 拖拽结束调用
   */
        //2.2应用于目标元素的事件
/*
       ondragenter : 拖拽进入时调用
            ondragover :  拖拽到目标元素时调用
            ondrop :      拖拽到目标元素,鼠标松开时调用
            ondragleave : 拖拽到目标元素,鼠标离开时调用


*/
   var p=document.querySelector("#pe");

 p.ondragstart=function(){
    console.log("ondragstart 开始");
 }
   p.ondragend=function(){
       console.log("ondragend 结束");
   }
   p.ondragleave=function(){
       console.log("ondragleave 离开");
   }
   p.ondrag=function(){
       console.log("ondrag 一致调用");
   }


</script>

</body>
</html>

16.拖拽通用

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        div{
            width: 200px;
            height: 200px;
            border: 1px solid #000;
            float: left;
            margin-right: 15px;

        }
        p{
          background-color: green;
        }
    </style>
</head>
<body>



<div id="div1" class="div1">
    <p id="pe" draggable="true">试试把我拖拽过去1</p>
    <p id="pe1" draggable="true">试试把我拖拽过去2</p>
</div>

<div id="div2" class="div2">

</div>





<script>
   //1.在H5中给对象元素添加draggable="true".才可实现拖拽.图片和超链接时默认可以拖拽的

    //2.拖拽事件
        //2.1应用于被拖拽元素的事件

*/
  //////////// var p=document.querySelector("#pe");
var obj=null;//*全局变量容易受到 污染，且占浏览器内存*
 document.ondragstart=function(e){
    console.log("ondragstart 开始"+e.target);
   e.target.style.opacity=0.5;
   e.target.parentNode.style.borderWidth="5px";
   obj=e.target;
   //*通过datatransfer来实现数据的存储与获取********
   //setData(format,data)
   //format:数据类型： text/html text/uri-list
   //data : 数据：一般指字符串值。
   e.dataTransfer.setData("text/html",e.target.id);
}
   document.ondragend=function(e){
       console.log("ondragend 结束"+e.target);
   }
   document.ondragleave=function(e){

/*

ondrop 事件不触发
需要在ondragenter  ondragover 中添加  e.preventDefault();用于阻止默认行为；
 */




 
</script>

</body>
</html>

17.地理定位(一般调用第三方接口:百度地图/谷歌/QQ等)

18web存储:storageSession / localSession

<body>
sessionStorage的使用:存储数据到本地,容量大小5M左右<br>
setItem(key,value): 设置数据<br>
getItem(key) : 获取数据<br>
removeItem(key): 删除数据<br>
clear():清空数据<br>

<br>
<input type="text" id="userName">
<input type="button" id="setData" value="设置数据">
<input type="button" id="getData" value="获取数据">
<input type="button" id="removeData" value="删除数据">


<script>
/*存储数据*/
/*
     1.数据仅存储在当前页面中,不存储在浏览器中.
    2.生命周期:关闭当前页面即消亡.
*/
document.querySelector("#setData").onclick=function () {
  var name=  document.querySelector("#userName").value;
    window.sessionStorage.setItem("userName",name);
}
/*获取值*/
document.querySelector("#getData").onclick=function () {
  var userName=  window.sessionStorage.getItem("userName");
  alert(userName);
}
//删除数据
document.querySelector("#removeData").onclick=function () {
    window.sessionStorage.removeItem("userName");
}




</script>


</body>


---------------------


<body>
localStorage的使用:存储数据到*硬盘*上,容量大小20M左右<br>
setItem(key,value): 设置数据<br>
getItem(key) : 获取数据<br>
removeItem(key): 删除数据<br>
clear():清空数据<br>

<br>
<input type="text" id="userName">
<input type="button" id="setData" value="设置数据">
<input type="button" id="getData" value="获取数据">
<input type="button" id="removeData" value="删除数据">


<script>
    /*存储数据*/

    document.querySelector("#setData").onclick=function () {
        var name=  document.querySelector("#userName").value;
        window.localStorage.setItem("userName",name);
    }
    /*获取值*/
    document.querySelector("#getData").onclick=function () {
        var userName=  window.localStorage.getItem("userName");
        alert(userName);
    }
    //删除数据
    document.querySelector("#removeData").onclick=function () {
        window.localStorage.removeItem("userName");
    }




</script>


</body>

19.应用缓存

<!DOCTYPE html>
<!-- manifest: 应用程序缓存清单文件的路径  建议文件的扩展名是appcache,本质就是个文本文件 -->
<html lang="en" manifest="manifest.appcache">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        img{
            width: 300px;
            display: block;
        }

    </style>
</head>
<body>

<img src="images/l1.jpg" alt="">
<img src="images/l2.jpg" alt="">
<img src="images/l3.jpg" alt="">
<img src="images/l4.jpg" alt="">

</body>
</html>

-----------以下是manifest.appcache文件内容---------------------


CACHE MANIFEST
#上面代码必须是当前文档的第一句
#后面写注释

#需要缓存的文件清单列表
CACHE:
#下面需要缓存的清单列表
images/l1.jpg
images/l2.jpg
# * :代表所有文件

#每一次都需要从服务器获取的文件清单列表
NETWORK:
images/l3.jpg




#配置文件如果无法获取则使用指定的文件进行替代
FALLBACK:
images/l4.jpg images/1.png
# /:代表所有文件
