jquery弹出层插件，支持消息提示、错误提示、确认框提示等。交互体验度非常好，大家都用微信支付、支付宝等完成用户体验度非常的不错。本插件至少要支持IE9+。使用方式也非常的简单、粗暴，很符合大众的jquery插件使用方法。
先给大家演示效果：
代码如下：
<h1>Sweet Alert</h1> <h2>A beautiful replacement for JavaScript's "Alert"</h2> <button>Download</button> <h3>So... What does it do?</h3> <p>Here's a comparison of a standard error message. The first one uses the built-in <strong>alert</strong>-function, while the second is using <strong>sweetAlert</strong>.</p> <div> <h4>Normal alert</h4> <button>Show error message</button> <h5>Code:</h5> <pre><span>alert</span>(<span>"Oops... Something went wrong!"</span>); </pre> <div></div> </div> <div> <h4>Sweet Alert</h4> <button>Show error message</button> <h5>Code:</h5> <pre><span>sweetAlert</span>(<span>"Oops..."</span>, <span>"Something went wrong!"</span>, <span>"error"</span>);</pre> </div> <p>Pretty cool huh? SweetAlert automatically centers itself on the page and looks great no matter if you're using a desktop computer, mobile or tablet. It's even highly customizeable, as you can see below!</p> <h3>More examples</h3> <p>In these examples, we're using the shorthand function <strong>swal</strong> to call sweetAlert.</p> <ul> <li> <div> <p>A basic message</p> <button>Try me!</button> </div> <pre><span>swal</span>(<span>"Here's a message!"</span>)</pre> </li> <li> <div> <p>A title with a text under</p> <button>Try me!</button> </div> <pre><span>swal</span>(<span>"Here's a message!"</span>, <span>"It's pretty, isn't it?"</span>)</pre> </li> <li> <div> <p>A success message!</p> <button>Try me!</button> </div> <pre><span>swal</span>(<span>"Good job!"</span>, <span>"You clicked the button!"</span>, <span>"success"</span>)</pre> </li> <li> <div> <p>A warning message, with a function attached to the "Confirm"-button...</p> <button>Try me!</button> </div>
