Question

我需要从页面搜索文本。我发现这个好的链接但是我想修改一些东西 https://github.com/nmartynenko/jquery-search-plugin.Actually其中只使用了正常工作的下一个和上一个按钮。但是我需要再添加一个这样的功能。

1）添加一个搜索按钮点击它会突出显示第一个发生的搜索文本，或者说找不到匹配项。之后它不会做任何事情。 2）选择下一个后，它将从第二个出现的文本中搜索，然后是下一个..

这是我的代码..

试试这个：

查看是否有任何事件，如果有，则查找第一次出现。

if(searcher.getConcurrencesNumber() > 0){
    searcher.findConcurrence(0);
}

如何在查询中搜索具有搜索，下一个，上一个按钮的文本
