Jquery自动完成匹配字符串中的多个无序单词 [英] Jquery Autocomplete matching multiple unordered words in a string
问题描述
我正在尝试显示输入的搜索字词的最佳匹配。例如
I am trying to show the best match of the search term typed in. For example
现在Jquery没有给我想要的效果。当我输入：今天一个时，自动填充功能将不显示任何内容，但如果我输入一天，则会显示以该顺序中的这两个单词开头的搜索结果。我想今天一个来显示一天是第一天，也就是今天。我希望搜索结果显示在其中包含这些单词的顺序并不重要。我在这里看了一下，却找不到这样的东西，这似乎是一种常见的搜索方法，我看不出为什么没有人问过这个问题。是否有处理此问题的内置方法？
Right now Jquery does not give me the desired effect. When I type: one today the autocomplete will show nothing but if I type one day it will show the search results that start with those two words in that order. I want one today to show up one day is the first and last today. I want the search results to show up that have those words in them the ordering is not important. I have looked through here and could find nothing like this, it seems like such a common searching method I cannot see why no one has asked this question. Is there a built in method that handles this?

推荐答案
尝试覆盖自动完成提供的默认过滤器逻辑。
Try overriding the default filter logic provided by auto complete.
// Overrides the default autocomplete filter function to search for matched on atleast 1 word in each of the input term's words
$.ui.autocomplete.filter = function (array, terms) {
arrayOfTerms = terms.split(" ");
var term = $.map(arrayOfTerms, function (tm) {
return $.ui.autocomplete.escapeRegex(tm);
}).join('|');
var matcher = new RegExp("\\b" + term, "i");
return $.grep(array, function (value) {
return matcher.test(value.label || value.value || value);
});
};
Fiddle
或创建自己的过滤器功能并处理搜索的返回，因此保持完整的过滤器功能。
Or create your own filter function and handle the search's return, so keeping complete's filter function as it is.
function customFilter(array, terms) {
arrayOfTerms = terms.split(" ");
var term = $.map(arrayOfTerms, function (tm) {
return $.ui.autocomplete.escapeRegex(tm);
}).join('|');
var matcher = new RegExp("\\b" + term, "i");
return $.grep(array, function (value) {
return matcher.test(value.label || value.value || value);
});
};
$("#tags").autocomplete({
source: availableTags,
multiple: true,
mustMatch: false
,source: function (request, response) {
response(customFilter(
availableTags, request.term));
},
});
