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：
$(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();
});
javascript代码如下：
