// 利用 jquery+iframe 做一个ajax上传效果

/*
思路:
1: 点击"提交"时的瞬间,生成一个iframe对象,插入body中
2: 修改form的target ,为iframe的name值
3: 给iframe加1个事件 ,onload
*/

$(
 function() {
  $(&#39;input:button&#39;).click(function(){
   //alert(&#39;s&#39;);
   var ifmname = &#39;ifm&#39; + Math.random();
   var ifm = $(&#39;<iframe width="0" height="0" frameborder="0" name="&#39;+ ifmname +&#39;">&#39;);
   ifm.appendTo($(&#39;body&#39;));

   $(&#39;form&#39;).attr(&#39;target&#39;,ifmname);
   $(&#39;form&#39;).submit();

   $(&#39;#progress&#39;).html(&#39;<img src="<img src="http://files.php.cn/file_images/article/201708/loading.gif" alt="" />" border="0">&#39;);
   ifm.load(function(){
    $(&#39;#progress&#39;).html(&#39;上传完毕&#39;);
    this.remove();
   });

  }); 
 }
);


</script>
<style type="text/css">
</style>
</head>
 <body>
  <p id="progress"></p>
  <form action="upfile.php" method="post" enctype="multipart/form-data" target="upfile">
   <input type="file" name="pic" /><br />
   <input type="button" value="提交" />
  </form>  
 </body>
</html>

Copy after login

upfile.php

 echo move_uploaded_file($_FILES[&#39;pic&#39;][&#39;tmp_name&#39;],&#39;./upload/&#39; . $_FILES[&#39;pic&#39;][&#39;name&#39;]) ? &#39;OK&#39;:&#39;fail&#39;;

Copy after login
