jQuery UI 是一个建立在 jQuery JavaScript 库上的小部件和交互库,可以使用它创建高度交互的 Web 应用程序。
在web页面的开发过程中,在添加元素的时候需要用到弹出窗口添加元素,最简便的就是直接通过一个隐藏的form来提交,在表单显示的时候通过js设置使得页面变暗和不可选,但是这样做未免过于麻烦,所需要的js语句也特别冗长,因此使用jQuery ui所提供的模态表单则显得简洁不少:
需要提到的是,jQueryui需要从 jQuery UI 网站上下载 jQuery UI 的副本:http://jqueryui.com/download/
然后根据自己的选择下载相应的组件
或者也可以通过jQueryUI的cdn来加载,不过在网速不佳的情况下有加载失败的可能性,下面是jQueryUI的cdn地址
官网CDN:http://code.jquery.com/ui/1.12.1/
大陆CDN加速:

接着介绍模态表单的创建:

效果如下:
点击创建新用户后,原页面变暗,按钮和元素不可选:
