用户界面-jQuery UI自动完成多项搜索



我正在尝试使用jQuery UI自动完成功能。经过一番搜索,在简单地编写自己的解决方案之前,也许已经有了可用的解决方案。

我以前使用过jQuery插件http://bassistance.de/jquery-plugins/jquery-plugin-autocomplete/但是由于各种原因想要迁移到集成在UI中的那个。

目前有两项挑战我。

所选术语高亮显示和多个术语搜索/选择以及如何实现这些功能

这是一个小提琴页:http://jsfiddle.net/vapc2/以显示示例。输入"ants",它会高亮显示蚂蚁。但如果我键入"ants-jill-hill",它应该选择并突出显示所有带有"ant"、所有带有"jill"和所有带有"hill"的条目,而不是像现在这样什么都没有。基本上,如果一个术语出现在任何地方,在任何答案中,我都想返回该值并突出显示该术语,即使它不是完全匹配的,只要它包含在某个地方的答案中。因此,如果我键入"ant bug",我希望返回所有带有这两个单词中任一个的条目。

假设我有以下示例JSON对象:

var sampleAnswers = [
    {
    "id": "00450",
    "label": "Ants, Ants on a hill near Jill",
    "Category": "Ants",
    "value": "hill ant"},
{
    "id": "00450",
    "label": "Ants, Ant not on a hill",
    "Category": "Ants",
    "value": "regular ant"},
{
    "id": "00452",
    "label": "Some ants on a hill",
    "Category": "Ants",
    "value": "hill ants"},
{
    "id": "00454",
    "label": "Red ants on a hill near Jill",
    "Category": "Ants",
    "value": "hill ant red"},
{
    "id": "00470",
    "label": "Bugs on a rug",
    "Category": "bugs",
    "value": "rug bug"},
{
    "id": "00472",
    "label": "rug bugs under the rug",
    "Category": "bugs",
    "value": "rug bug"},
{
    "id": "69000",
    "label": "bed bugs",
    "Category": "bed",
    "value": "bed bugs"},
{
    "id": "69005",
    "label": "Large complicated bed bugs",
    "Category": "bugs",
    "value": "bed bug"},
{
    "id": "69020",
    "label": "red bed bugs",
    "Category": "bugs",
    "value": "red bugs"}
];
function replaceWords(wordsy, text) {
    //var re = '(' + words.join('|') + ')(?![^<]*(?:</script|>))',
    var re = '(' + wordsy + ')(?![^<]*(?:</script|>))',
        regExp = new RegExp(re, 'ig'),
        sTag = "<span class='autoCompleteWord'>",
        eTag = "</span>";
    return text.replace(regExp, sTag + '$&' + eTag);
};
$("#tags").autocomplete({
    minLength: 1,
    source: sampleAnswers,
    delay: 1000,
    focus: function(event, ui) {
        $("#cpt").val(ui.item.label);
        return false;
    },
    open: function(event, ui) {
        var myValue = $(this).val(); //get typed
        $("ul.ui-autocomplete li a").each(function() {
            var autoCompleteRow = $(this);
            var htmlString = autoCompleteRow.html();
            var words = myValue.split(" ");
            $('#mesText2').val(myValue + ":" + words.length);
            var i = words.length;
            while (i--) {
                htmlString = replaceWords(words[i], htmlString);
            };
            autoCompleteRow.html(htmlString);
        });
    },
    select: function(event, ui) {
        var hasValue = (ui.item.value != undefined && ui.item.value != "" && ui.item.value != null);
        $("#bugid").val(ui.item.id);
        $("#bugcategory").val(ui.item.Category);
        $("#bug").val(hasValue ? ui.item.value : ui.item.label);
        $("#bugLabel").val(ui.item.label);
        return false;
    }
}).data("autocomplete")._renderItem = function(ul, item) {
    return $("<li></li>").data("item.autocomplete", item).append("<a>" + item.id + " <span class='autoCompCat'>" + item.Category + "</span> (Category)<br/>" + item.label + " <br/><span class='autoCompCpt'>" + item.value + "</span>" + "</a>").appendTo(ul);
};

jQuery UI最新版本,首选jQuery 1.6。

编辑:我尝试使用以下"来源":

    source: function(request, response) {
        var matcher = new RegExp($.ui.autocomplete.escapeRegex(request.term), "i");
        response($.each(sampleAnswers, function() {
            var text = $(this).label;
            if (this.value && (!request.term || matcher.test(text)))
                return {
                    label: text.replace(
                                        new RegExp(
                                            "(?![^&;]+;)(?!<[^<>]*)(" +
                                            $.ui.autocomplete.escapeRegex(request.term) +
                                            ")(?![^<>]*>)(?![^&;]+;)", "gi"
                                        ), "<strong>$1</strong>"),
                    value: text,
                    option: this
                };
        }));
    },

但这返回的结果不包括我键入的术语列表(如"红色bug"返回的项目00450300452),我不希望显示这些术语。请参阅此小提琴了解更新:http://jsfiddle.net/vapc2/1/

好的,我解决了它返回所有结果而不过滤的问题

http://jsfiddle.net/vapc2/4/

以下是我所做的代码更改——需要注意的事项:

  • 我把$(这个)改成了这个
  • 我添加了一个结果数组,只有在测试通过时才添加(根据我最初的评论)
  • 您的正则表达式不起作用,但我认为这超出了这个问题的范围。

    source: function(request, response) {
      var matcher = new RegExp($.ui.autocomplete.escapeRegex(request.term), "i");
      var resultset = [];
      $.each(sampleAnswers, function() {
        var t = this.label;
        if (this.value && (!request.term || matcher.test(t)))
        {
           resultset.push( {
           label: t.replace(
                     new RegExp(
                             "(?![^&;]+;)(?!<[^<>]*)(" +
                             $.ui.autocomplete.escapeRegex(request.term) +
                             ")(?![^<>]*>)(?![^&;]+;)", "gi"
                           ), "<strong>$1</strong>"),
           value: t,
           option: this
         });
       }  
       return;
     });
     response(resultset);
    },
