//前台页面弹出消息对话框 一般是操作成功弹出一个提示 点击确定跳转到其他页面
//或者输入框填写不正确,弹出对话框提示 
//有遮蔽层
//msg:显示的信息
//type:提示信息是提示正确还是错误 正确 right 错误 error
//urlClose:点击关闭按钮跳转的页面地址 不跳转则为空
//urlOk:点击确定按钮跳转的页面地址 不跳转则为空
//timeClose:是否需要经过几秒后自动关闭 目前暂定3秒 取值 true false
//imgType:图片路径 和如调用这个函数页面是和Images在同一级下则 imgType设置1 如调用这个函数的页面在一个与images同一级的子目录里面则imgType 设置2
//imgType是解决图片路径问题的暂时替代方法,如有解决方案会及时更新
//示例:
//页面中最下方:
//<div class="mask" id="mask_info" style="display: none;"></div>
