页面引入插件文件

<script type="text/javascript" src="mh_dialog/js/mh_dialog.js"></script>

页面想怎么调用就怎么调用，就是那么任性

<a class="a" href="javascript:mh_dialogShow('mh_success','更新成功!');">提示更新成功</a>
<a class="a" href="javascript:mh_dialogShow('mh_loading','内容加载!');">提示内容加载</a>
<a class="a" href="javascript:mh_dialogShow('mh_warning','输入有误!');">提示输入有误</a>
<a class="a" href="javascript:mh_dialogShow('mh_error','更新失败!');">提示更新失败</a>
<a class="a" href="javascript:mh_dialogShow('mh_success','更新成功!',2,true);">提示更新成功2秒后自动关闭</a>
<a class="a" href="javascript:mh_dialogShow('mh_loading','内容加载!',2,true);">提示内容加载2秒后自动关闭</a>
<a class="a" href="javascript:mh_dialogShow('mh_warning','输入有误!',2,true);">提示输入有误2秒后自动关闭</a>
