本例用到其他2个php class.upload.php和 functions.php还有css和js以及img文件

完整实例代码点击此处本站下载。

效果图如下:

实现代码如下:

JavaScript代码如下:
复制代码 代码如下:<script type="text/javascript"> 
$(document).ready(function() { 
    $("#filelist").niceScroll({ 
        cursorwidth: "8px", 
        cursorborderradius: "0px", 
        cursoropacitymin: 0.1, 
        cursoropacitymax: 0.3 
    }); 
 
    $(".side-pane").niceScroll({ 
        cursorwidth: "8px", 
        cursorborderradius: "0px", 
        cursoropacitymin: 0.1, 
        cursoropacitymax: 0.3 
    }); 
 
    $(".time").timeago(); 
}); 
</script> 

javascript代码如下:
