Javascript jQuery显示前两个回复，隐藏其余回复

评论分为三个层次。显示了祖父母（深度1）的所有评论。我想显示前两个对每个祖父母评论的深度2回复（父类评论），并使用切换按钮隐藏和显示其余内容（理想情况下是在“隐藏”和“显示”之间切换文本）。除非只有一个深度2回复，否则深度3回复应全部隐藏，如果可能，应显示第一个深度3回复，以便在所有场景中总共显示两个回复

我已成功地在一个页面中切换所有深度3回复

以下是标记和javascript（已更新）：

评论-677


评论-678


评论-680


评论-686


评论-688


评论-689






评论-679


评论-682


评论-690




评论-691

基本上与第三级相同，但使用

gt（）

（零基）选择器跳过前两个回复：

$（“#全部切换”）。单击（函数（）{

那个家伙应该做什么？
