基于JavaScript实现模态窗口插件（支持回调）

基于Javascript写的模态窗口

调用接口

Messbox.show({
    title:"标题",          //模态窗口的标题
    content:"内容",        //模态窗口的显示内容，支持html文本
    okText:"确定",         //确定按钮标题,如果不配置默认显示确定
    cancelText:"取消",     //取消按钮标题，如果不配置则不显示取消按钮
    okEvent:function(){},  //确定按钮单击时的执行的事件，如果不配置默认是关闭窗口
});
