输入标签内容失败

Error message

输入标签内容失败

What it means

inputTag wraps failure from humanize.Type when typing the actual tag text after the '#'. The '#' was typed successfully but sending the tag body to the content element failed, so no tag text could be entered for autocomplete. Indicates the element or browser session failed mid-sequence.

Solutions

1. Verify the element is still attached after typing '#' (WaitStable before typing the tag).
2. Check the context deadline is generous enough for per-character typing.
3. Retry the whole inputTag call for the failing tag.
4. Validate tag content (no newlines/control chars) before publishing, as such chars can break typing.

Example fix

// before
if err := humanize.Type(ctx, contentElem, tag); err != nil {
    return errors.Wrap(err, "输入标签内容失败")
}
// after
time.Sleep(300 * time.Millisecond) // 等编辑器稳定
if err := contentElem.WaitStable(200 * time.Millisecond); err != nil {
    return errors.Wrap(err, "编辑器元素失效")
}
if err := humanize.Type(ctx, contentElem, tag); err != nil {
    return errors.Wrap(err, "输入标签内容失败")
}

if strings.ContainsAny(tag, "\n\r\t") { return errors.New("tag 含非法字符") }
if err := contentElem.WaitStable(200 * time.Millisecond); err != nil { return err }

func isValidTag(tag string) bool { return tag != "" && !strings.ContainsAny(tag, "\n\r\t") }

if err := inputTag(ctx, contentElem, tag); err != nil {
    slog.Warn("标签输入失败，重试一次", "tag", tag)
    err = inputTag(ctx, contentElem, tag)
}

When it happens

Trigger: Same as 190 but occurring on the second humanize.Type call: element detached after the 200ms wait, page busy rendering the autocomplete dropdown, browser connection lost, or context cancelled during typing.

Common situations: Tags containing characters needing IME/keyboard handling that the humanizer types slowly, exceeding timeouts; page re-render triggered by the '#'; user context deadline exceeded on slow machines.
