我希望得到我的Shopify内我的搜索栏自动完成设置阿贾克斯/ jQuery的自动完成这个商城 - 液体使用和Ajax在搜索框（Shopify）
我发现这个教程，并实现它，因为它说，然而它不起作用，网站上的任何搜索栏上都没有自动完成 - 我认为它可能比较陈旧，并且在最小/ Shopify搜索功能的更新/更改之前写入。
https://help.shopify.com/themes/customization/store/enable-autocomplete-for-search-boxes
我可以用Chrome浏览器开发工具，遵循它通过，而现在看来似乎被卡住的地方增加了搜索结果列表$('<ul class="search-results"></ul>').appendTo($(this)).hide();，追踪网页的HTML时，这不会出现。这意味着当它稍后尝试查找此列表var resultsList = form.find('.search-results');时，它不会找到它，因此无法填充项目。
我正在运行Minimal主题。 该网站是testing site在顶部灰色标题搜索栏，并且还通/搜索
通过Shopify内置演示此自动完成的测试位点位于[HTTPS]：//search-autocomplete.myshopify.com/ 。在页面加载时，<ul>追加已经存在。
编辑：
做了一些更多的挖掘，我在开发者工具碰到这个错误绊倒 -
Uncaught ReferenceError: jQuery is not defined at (index):7031
哪个，你猜对了，下面的jQuery代码的第一行。 $(function() {任何想法为什么jQuery是未定义的？该脚本包含在</body>之前的索引文件的底部，因此jquery.min.js应该在那之前加载，网站上的其他jQuery工作正常。在测试现场
