做项目时，很多时候都需要弹窗提示。如果要求不是很严格的项目，直接使用alert就可以搞定。对于需要高度定制化的项目，而且要求比较高的时候，就需要设计符合整体风格的弹出层，这种有美工帮忙，也比较好搞定。最麻烦的是一些工期比较紧，alert这种简陋的提示又不满足要求，又没时间做一些精美的弹出模块的项目。
我最近遇到很多的这种情况的Web App项目，项目工期催的很紧，又不可以直接使用alert，所以自己写了个简洁的jquery插件，使用非常方便，而且整体样式简洁大方。项目源码的地址，https://github.com/SeedQiGit/BriefPopUp
项目使用时需要引入1.7版本以上的jquery，其实如果要使用1.7一下版本，直接修改jquery.popup.js开头的源代码，把on绑定改成live即可。
原版on绑定
$(document).on("click", '.briefPopUp', function (event) {
event.preventDefault();
var modalLocation = $(this).attr('data-briefPopUp-id');
$('#' + modalLocation).reveal($(this).data());
});修改之后的绑定
$('a['data-briefPopUp-id]').live('click', function(event) {
event.preventDefault();
var modalLocation = $(this).attr('data-briefPopUp-id');
$('#'+modalLocation).reveal($(this).data());
});这样就可以在1.7一下版本使用了。
最后js源码
(function($) {
/*---------------------------
