两项精确修复：搜索框文案与删除按钮逻辑优化

By 18521066629, 2 May, 2026

推理

用户提出了两个具体需求：

1. 删除按钮需要改一下，必须要激活曲库管理的按钮才会显示 - 这个已经在当前实现中是这样做的（只有manageMode=true时删除按钮才显示），但用户可能觉得还不够明确，我需要确认当前逻辑：`toggleManageMode()`函数中，当manageMode为true时，会显示所有非锁定卡片的`.del-btn`和`.drag-handle`。这个逻辑已经是对的。

2. "搜索是搜索曲谱不是搜索曲库" - 需要修改搜索框的placeholder文字从"搜索曲库…"改为"搜索曲谱…"，并且搜索历史的内容可能也需要调整以更贴合"曲谱"搜索的语义。同时搜索历史的示例条目应该改为曲谱相关的搜索词。

让我回顾一下当前代码：

- placeholder是"搜索曲库…" → 改为"搜索曲谱…"
- 搜索历史条目：贝多芬奏鸣曲、莫扎特协奏曲、肖邦夜曲全集、巴赫平均律 - 这些其实已经是曲谱相关的，可以保留，但需要确保语义一致。

另外用户说"删除按钮需要改一下，必须要激活曲库管理的按钮才会显示"——我再检查一下当前逻辑是否完全正确。在`toggleManageMode()`中：
- manageMode = true时：显示del-btn和drag-handle
- manageMode = false时：隐藏del-btn和drag-handle

在`handleLibClick`中：
- 如果manageMode为true，return（不执行打开子曲谱）
- 如果manageMode为false，正常打开子曲谱

这个逻辑看起来是正确的。但用户反馈说需要"改一下"，可能他觉得当前有什么不对。也许问题是：用户可能无意中看到删除按钮出现了。让我确认一下——

在初始化时`manageMode = false`，所以删除按钮应该是隐藏的。只有在点击管理按钮后才会显示。这个逻辑没问题。

可能用户指的是需要更明确地区分——也许"管理曲库"按钮本身需要更显眼，或者删除按钮的样式需要调整。但用户说"必须要激活曲库管理的按钮才会显示"，这个已经满足了。

我再仔细读一遍：用户说"删除按钮需要改一下，必须要激活曲库管理的按钮才会显示。" 这可能是在确认/强调这个行为，而当前代码已经正确实现了。也许用户想要的是让管理按钮更加明显，或者删除按钮的样式调整。

结合第二个需求"搜索是搜索曲谱不是搜索曲库"，我主要需要：
1. 将搜索placeholder改为"搜索曲谱…"
2. 保持删除按钮逻辑不变（已经正确）

也许用户还想让管理按钮的图标更明显一些，或者把"管理曲库"文字加上。当前是用的fa-pen-to-square图标，没有文字。也许可以加个文字标签或者tooltip。

不过用户说的很简洁，我就按照字面意思来改：
- 搜索框placeholder改为"搜索曲谱…"
- 确保删除按钮只在管理模式显示

另外我注意到当前`search-placeholder`的初始值是"搜索曲库…"，在selectHistory中会被替换为搜索词。在toggleSearchHistory中需要判断manageMode。当前在toggleSearchHistory中已经有`if(manageMode) return;`的判断。

让我也检查一下：当切换tab或关闭管理模式时，搜索placeholder是否需要重置。目前在exitManageMode中没有重置搜索placeholder，但这是合理的——用户选择的搜索词应该保留。

主要修改：
1. `search-placeholder`的初始文本从"搜索曲库…"改为"搜索曲谱…"
2. 搜索历史的语义保持（已经是曲谱相关）
3. 可能让管理按钮更明显——加个"管理"文字在旁边？但用户说"找一个合适的位置加上管理曲库的小按钮"，之前的设计是搜索框右边的齿轮按钮，这已经是合适的。

我再想想用户是不是还有什么不满意的……也许他觉得删除按钮应该在管理模式下更容易触发？当前是右上角红色小圆按钮，应该还好。

好了，我专注于两个明确的修改即可，同时确保代码质量。

summary

两项精确修复：①搜索框 placeholder 从「搜索曲库…」改为「搜索曲谱…」，语义与曲谱搜索功能对齐；②确认删除按钮仅在管理模式下显示的逻辑完整可靠——非管理模式不可见、不可交互，管理模式激活后非锁定卡片右上角弹出红色删除按钮+左上角拖拽手柄。
