使用本指南在标题为results.html
的新页面中显示搜索结果时遇到了一些问题。
它的设置似乎是在进行搜索的页面上显示结果,这不是我想要的。
我想做的是在index.html
中有一个搜索框,它在按下包含搜索结果的按钮后打开一个新页面。
目前,在任何页面上进行的任何搜索都会在那里显示结果。

_layout/index.html
{% include search-lunr.html %}
我唯一能想到的就是在表单中添加一个操作,然后打开_layout/results.html
,这实际上不会改变任何事情。
如有任何帮助,我们将不胜感激。谢谢
如果您只想在单独的页面上显示搜索结果,您会希望搜索表单有一个指向它的操作。该术语将传递到该页面,然后该页面可以处理它并显示搜索结果。
这个模板展示了这个确切的流程:
- 回购:https://github.com/CloudCannon/edition-jekyll-template
- 现场演示:https://long-pig.cloudvent.net/
这是一个非常好的解决方案,因为您的网站访问者只需要在执行搜索时加载并运行该代码,这对于大小合理的索引来说是一个巨大的节省。
要用上面的代码大致复制它:
-
从
index.html
中删除{% include search-lunr.html %}
。 -
把这个放在
index.html
:上<form action="{{ site.baseurl }}/search/" method="get"> <input type="text" name="q"> <input type="submit" value="Search"> </form>
-
然后在您的
search.html
:中... {% include search-lunr.html %} <script> function getQueryVariable(variable) { var query = window.location.search.substring(1), vars = query.split("&"); for (var i = 0; i < vars.length; i++) { var pair = vars[i].split("="); if (pair[0] === variable) { return decodeURIComponent(pair[1].replace(/+/g, '%20')).trim(); } } } var query = decodeURIComponent((getQueryVariable("q") || "").replace(/+/g, "%20")); lunr_search(query); </script> ...
