The citation shows as (Author et al., 2020b, 2020a), is it right?

johnmy

The following style is used:
title Elsevier - Harvard (with titles)
ID 188BET靠谱吗//www.brodersterzo.com/styles/elsevier-harvard

When two items with same first author and year ( https://gist.github.com/redleafnew/62779077eaaa3004e4d5df1e41faec9d) are insterted (the item wit title of Metabolic Engineering for Production of Functional Polysaccharides is inserted firstly)

the citation shows as:

(Schilling et al., 2020b, 2020a)

The bibliography shows normally.

Could the citation show as (Schilling et al., 2020a, 2020b)?

Any idea？

Yes, it should be a, b.
technical: I think this is a bug in the citeproc-js -- the style sorts in-text citations by the same author macro as the bibliography, so they should be in the same order, but it looks like citeproc-js applies the et-al from cs:citation and then does something....weird.
I think we'll want to try to get this fixed in citeproc, In the meantime, you can fix this by changing the first sort key in citation to something like

Done, many thanks.

I don't think it's a bug of citeproc-js.

I've slightly modified citeproc-js to print the sort keys (as follow).

[test_Test] sort keys (bibliography_sort): Schilling|C.,|Koffas|M.A.G.,|Sieber|V.,|Schmid|J.|,120200000100000000|
[test_Test] sort keys (bibliography_sort): Schilling|C.,|Badri|A.,|Sieber|V.,|Koffas|M.,|Schmid|J.|,120200000100000000|
[test_Test] sort keys (citation_sort): Schilling|C.|,120200000100000000|
[test_Test] sort keys (citation_sort): Schilling|C.|,120200000100000000|

The citation_sort keys of both cites are identical and therefore they appear in the order as they cited (ITEM-1: 2020b -> ITEM-2: 2020a).

adamsmith

right, but I don't think citeproc-js should apply et-al to the sort key when it's just in cs:citation --the spec isn't as clear on this as we'd maybe want, but see

Second, et-al abbreviation can be used (using either the et-al-min/et-al-subsequent-min, et-al-use-first/et-al-subsequent-use-first, and et-al-use-last options defined for the macro, or the overriding names-min, names-use-first and names-use-last attributes set on cs:key).

Note that this explicitly doesn't mention et-al set on the parent node.

Conceptually, the current behavior
a) means that sorting by the exact same sort condition in cs:citation and cs:bibliography leads to different outcomes and
b) it's impossible to not set et al sorting for an in-text citation without resorting to the somewhat ugly "just use large number for names-min" hack I have above.

edit: I said "something weird" because johnmy had mentioned citing the "Metabolic" paper first, but I see the same as you, i.e.sorting by order in which items are cited.
