Simple pagination with only next and previous buttons
提问by zack
Just have a simple question. This is a pagination code that use in one of my websites. i just want to make this more simple. Remove all page numbers and just keep "Next" and "Previous" links.
只是有一个简单的问题。这是在我的一个网站中使用的分页代码。我只是想让这更简单。删除所有页码，只保留“下一页”和“上一页”链接。
Can anyone point me out what part of the script that i need to remove to get rid of page numbers. Really appreciate your help.
谁能指出我需要删除脚本的哪一部分才能摆脱页码。真的很感谢你的帮助。
