Question

我找到了一些展示如何突出显示多个匹配项的示例，例如：如果我输入“艺术设计”，我希望它突出显示为“艺术和设计程度”

以下示例（尽管使用静态数组）是我所追求的： http://jsfiddle.net/Q4jy9/1/

但是，我不知道如何使这个工作的远程PHP数据源。下面是我正在使用的当前代码。每个按键都会将该术语发送到我的php并从数据库中选择匹配项。

有没有办法可以更改下面的脚本以允许突出显示多个单词/匹配，或者更改上面链接中的脚本以使用外部数据源？

var termTemplate = "<span class='ui-autocomplete-term'>%s</span>";
$("#f input").autocomplete({
   source: "livesearch.php",
   open: function(e, ui) {
      var origKeyword = $("#f input").val();
      var acData = $(this).data('autocomplete');
      acData.menu.element.find('a').each(function() {
         var me = $(this);
         var regex = new RegExp(acData.term, "gi");
         me.html(me.text().replace(regex, function(matched) {
            return termTemplate.replace('%s', matched);
         }));
      });

   },
   select: function(event, ui) {
      var keyword = $("#f input").val();
      $("#f input").val('');
      window.location.href = 'MYURLHERE?VARIABLE=' + ui.item.value;
      return false;
   },
   focus: function(event, ui) {
      return false;
   }
});

尝试这样的事情（匹配的功能是从你的jsfiddle复制和粘贴）：

$("#f input").autocomplete({
    source: function(request, response) {
        $.getJSON("livesearch.php", request, function(data, status, xhr ) {

            var matchArry   = availableTags.slice ();
            var srchTerms   = $.trim (requestObj.term).split (/\s+/);

            $.each (srchTerms, function (J, term) {
                var regX  = new RegExp (term, "i");
                matchArry = $.map (matchArry, function (item) {
                    return regX.test (item)  ?  item  : null;
                });
            });

            response(matchArray);
        });
    },

    ...

});

这是基于jquery UI示例：http://jqueryui.com/demos/autocomplete/#remote-with-cache
