如何修改dede文章页上一篇下一篇＂没有了＂

dedecms上一篇下一篇调用标签：

{dede:prenext get='pre'/}
{dede:prenext get='next'/}

如何自定义织梦dedecms上一篇下一篇标签调用内容呢，例如修改为仅调用上一篇下一篇的链接呢：

1.找到include目录下的这个文件：arc.archives.class.php

找到这几行：

$this->PreNext['pre'] = "上一篇：{$preRow['title']} ";
$this->PreNext['pre'] = "上一篇：没有了";
$this->PreNext['next'] = "下一篇：{$nextRow['title']} ";
$this->PreNext['next'] = "下一篇：没有了 ";
删除“没有了”即可

2.也可以用下面的代码实现。

找到这几行：

$this->PreNext['pre'] = "上一篇：{$preRow['title']} ";
$this->PreNext['pre'] = "上一篇：没有了";
$this->PreNext['next'] = "下一篇：{$nextRow['title']} ";
$this->PreNext['next'] = "下一篇：没有了 ";

分别替换为以下几行：

$this->PreNext['pre'] = "$mlink";
$this->PreNext['pre'] = "javascript:window.alert('上一篇：没有了');";
$this->PreNext['next'] = "$mlink";
$this->PreNext['next'] = "javascript:window.alert('下一篇：没有了');";

以上是文章内容模型的上一篇下一篇调用标签。图集模型的修改地方如下：
找到这几行：
*$this->PreNext['preimg'] = " ";
 $this->PreNext['preimg'] ="";
$this->PreNext['nextimg'] = " ";
$this->PreNext['nextimg'] ="";

分别替换为以下几行：

 $this->PreNext['preimg'] = "$mlink";
$this->PreNext['preimg'] ="javascript:window.alert('对不起，没有上一图集了！');";
$this->PreNext['nextimg'] = "$mlink";
$this->PreNext['nextimg'] ="javascript:window.alert('对不起，没有下一图集了！');";
