我已经从 jsfiddle 中用你的 format 函数替换了它，但它仍然不起作用。看截图。
更新：
刚发现传递给formatRepo函数的值也包含搜索值。并且搜索值中没有属性 full_name。搜索词的 repo 值看起来像这样 {id: "test", text: "test"}，它没有 full_name 属性。所以我只是添加了一个像这样的条件 if(!repo.hasOwnProperty('full_name')){ console.log(repo); return repo.text; } 来评估它。
因此您的 formatRepo 函数将如下所示
function formatRepo (repo) {
if (repo.loading) return repo.text;
if(!repo.hasOwnProperty('full_name')){ console.log(repo); return repo.text; }
这适用于 tags:true 属性。
希望这对您有所帮助。
undefined 是由 tags:true 属性引起的。我刚刚在此处删除并创建了一个有效的 JSFiddle https://jsfiddle.net/y18sxt9L/
和 tags: true 当您希望用户创建自定义标签时使用。在您的情况下，您希望用户仅搜索客户并 select 显示结果中的值。所以你不需要 tags:true 属性。
Note that when tagging is enabled the user can select from
pre-existing options or create a new tag by picking the first choice,
which is what the user has typed into the search box so far.
有关 tags 的更多说明，请查看此处的文档 https://select2.github.io/examples.html#tags

我已将我的功能更新为如下所示，但它仍然不起作用。
function formatRepo (repo) {

我已经从 jsfiddle 中用你的 format 函数替换了它，但它仍然不起作用。看截图。
更新：
刚发现传递给formatRepo函数的值也包含搜索值。并且搜索值中没有属性 full_name。搜索词的 repo 值看起来像这样 {id: "test", text: "test"}，它没有 full_name 属性。所以我只是添加了一个像这样的条件 if(!repo.hasOwnProperty('full_name')){ console.log(repo); return repo.text; } 来评估它。
因此您的 formatRepo 函数将如下所示
function formatRepo (repo) {
if (repo.loading) return repo.text;
if(!repo.hasOwnProperty('full_name')){ console.log(repo); return repo.text; }
这适用于 tags:true 属性。
希望这对您有所帮助。
undefined 是由 tags:true 属性引起的。我刚刚在此处删除并创建了一个有效的 JSFiddle https://jsfiddle.net/y18sxt9L/
和 tags: true 当您希望用户创建自定义标签时使用。在您的情况下，您希望用户仅搜索客户并 select 显示结果中的值。所以你不需要 tags:true 属性。
Note that when tagging is enabled the user can select from pre-existing options or create a new tag by picking the first choice, which is what the user has typed into the search box so far.
有关 tags 的更多说明，请查看此处的文档 https://select2.github.io/examples.html#tags
