Javascript - 使用文本输入框过滤数据

Question

我正在尝试创建过滤功能，用户可以开始在输入框中输入文本，并且该功能将在用户输入时显示/隐藏数据。它还需要组合两个或多个单词，但仅显示具有该单词组合的结果，而不显示可以找到单词的数据(因为该功能目前正在运行)。我正在尝试创建这个，但我不知道该怎么做。

这是最后一个工作代码(JS Fiddle demo):

HTML:

<div class="gallery-search">
    <input type="text" name="input-filter" class=form-control id="input-filter" placeholder="Search Here">
</div>
<div>  
    <a class="gallery"  data-tags="chaos board nordic viking warriors display ship dock warhammer fantasy"></a>
    <a class="gallery" data-tags="modular necron obelisk pyramid ziggurat scenery gaming board wasteland warhammer 40k"></a>
    <a class="gallery" data-tags="modular nurgle imperial chaos gaming board toxic crossroad warhammer 40k"></a>
    <a class="gallery" data-tags="modular necron obelisk pyramid ziggurat scenery warhammer 40k"></a>
    <a class="gallery" data-tags="ork orc fort fortress modular palisade wood skaven scenery warhammer fantasy"></a>   
</div>

JS:

var inputFilter = $('#input-filter');
inputFilter.on('keyup', function() {

            var
                $this  = $(this),
                search = $this.val().toLowerCase(),
                words = search.split(/\s+/),
                data;

                if(search.length > 2){
                    $('.gallery').hide();
                    $('a[data-tags]').filter(function(){
                       // splitting the data-tags attribute to an array of words:
                       data = this.dataset.tags.split(/\s+/);

                       // looking to see if any of the words (from the value)
                       // are present in the array formed from the data-tags
                       // attribute, using Array.prototype.some() to iterate
                       // over the given array, returning a Boolean true or false:
                       return words.some(function (word) {
                           return data.indexOf(word) > -1;
                       });
                   }).show();
                }

                if(search == ''){
                    $('.gallery').show();
                }

        });

Answer 1

return  words.reduce(function(previousValue, currentValue, index, array) {
                    return previousValue &&  data.indexOf(currentValue) > -1;
                     },true);

最后的 true 是初始值，它是数组中第一个值的 previousValue
