根据匹配位置对自动完成UI结果进行排序
我想根据匹配发生的字符串中的位置对jQuery自动完成UI结果进行排序。 匹配是第一个字母的结果应优先于匹配位于字符串中间的结果。
搜索“M”应返回：
马特，迈克尔，萨姆，蒂姆，亚当，本杰明
相反，因为它现在只是按字母顺序返回项目，我得到了这个：
亚当，本杰明，马特，迈克尔，萨姆，蒂姆
不幸的是，看起来Autocomplete UI没有任何选项来执行此类操作，而只是按照收到的顺序显示结果。 让MySql执行排序不是一个选项，因为所有可能的匹配都是预加载的，因此我不会在每次按键时调用数据库。 有人做过这样的事吗？
您可以通过为source选项提供函数而不是简单数组来提供您想要的任何本地过滤逻辑。 这是一个快速示例，它将完成您想要的基础知识：
var source = ['Adam', 'Benjamin', 'Matt', 'Michael', 'Sam', 'Tim']; $("input").autocomplete({ source: function (request, response) { var term = $.ui.autocomplete.escapeRegex(request.term) , startsWithMatcher = new RegExp("^" + term, "i") , startsWith = $.grep(source, function(value) { return startsWithMatcher.test(value.label || value.value || value); }) , containsMatcher = new RegExp(term, "i") , contains = $.grep(source, function (value) { return $.inArray(value, startsWith) < 0 && containsMatcher.test(value.label || value.value || value); }); response(startsWith.concat(contains)); } });

基本上，逻辑是构建一个以术语开头的匹配数组，然后将其与包含该术语但不以其开头的匹配项连接起来。
性能可能是一个问题，尤其是$.inArray调用。 可能是一个更好的方法来完成这一部分，但希望这将给你一个很好的起点。
一种可能的优化：当它们进入startsWith时从源列表中剔除项目，然后在附加包含搜索字符串的内容时不需要测试重复。 然而，权衡是每次输入字符串改变时都需要重新生成源数组。
