我喜欢用此处显示的代码在每个页面中将排序的引用显示为脚注。除非您使用两个不同的参考书目，否则代码可以正常工作。在下面显示的示例中（相同代码如上链接+ 参考书目文件 + 定义了两个参考书目），第一个参考文献在文本中显示为 P1，但在脚注中显示为 0。可以修复此问题吗？任何帮助都将不胜感激...

答案1
代码缺少对 refcontext 的初始化\blx@getrefcontext{#1}。
\cbx@do您需要将的定义更改为
\def\cbx@do#1{%
\ifinlist{#1}{\cbx@savelist}
{\begingroup
\blx@resetdata
\blx@getrefcontext{#1}%
\blx@getdata@cite{#1}%
