Question

当我点击具有相同值的按钮并且我想要隐藏未被选中的其他值时，我试图按某个列值过滤我的表。我试图提取数据产品的价值。过滤器似乎根本不起作用。这是我的脚本文件中的代码。

$('.filter-btns.top input').on('click', function () {
    $('.filter-btns.top input').removeClass('active');
    $(this).addClass('active');
});

$('.filter-button').on('click', function () {
    var button = $(this);
    var name = button.attr('name');
    var count = 0;


    $('#results-tbody tr').each(function () {
        var element = $(this);
        element.data('filters', element.data('filters').replace(/button/g, ''));
        switch (name) {
            case 'flexitouch':
                if (element.data('product') !== "flexitouch") {
                    element.data('filters', element.data('filters') + 'button');
                }
                break;
            case 'actitouch':
                if (element.data('product') !== "actitouch") {
                    element.data('filters', element.data('filters') + 'button');
                }
                break;
            case 'entre':
                if (element.data('product') !== "entre") {
                    element.data('filters', element.data('filters') + 'button');
                }
                break;
        }
        count = count + hideOrShow(element);

    });
    setResultsCount(count);
});

这是它引用的cshtml文件

   <div class="filter-btns top">
        <h4 class="filter-heading">Quick Search By</h4>
        <input type="button" id="all" name="all" class="button1 filter-button active" value="All" />
        <input type="button" id="flexitouch" name="flexitouch" class="button1 filter-button" value="Flexitouch" />
        <input type="button" id="actitouch" name="actitouch" class="button1 filter-button" value="ACTitouch" />
        <input type="button" id="entre" name="entre" class="button1 filter-button" value="Entre" />
    </div>
  <table class="table results-table">
            <tr>
                <th><i id="count"> (@ViewBag.Count found) </i></th>
            </tr>
            <tbody id="reults-tbody">
                @foreach (var item in Model.SearchResults)
                {

Answer 1

我建议使用内置.filter()方法。如果您有一组用户，则可以使用此方法创建新的过滤数组。

使用示例：

HTML

<button class="agetrigger" data-age="25">25</button>
<button class="agetrigger" data-age="22">22</button>
<button class="agetrigger" data-age="28">28</button>

JS

 const students = [
  {
    "index": 0,
    "isActive": false,
    "age": 25,
    "eyeColor": "blue",
    "name": "Roach Hunter",
    "gender": "male"
  },
  {
    "index": 1,
    "isActive": true,
    "age": 22,
    "eyeColor": "brown",
    "name": "Dena Terrell",
    "gender": "female"
  },
  {
    "index": 2,
    "isActive": true,
    "age": 28,
    "eyeColor": "blue",
    "name": "Vanessa Guthrie",
    "gender": "female"
  }
];

var filterAge = null;
$('.agetrigger').on('click', function() {

  filterAge = $(this).data('age');    
  const getAgeStudent = students.filter(student => student.age >= filterAge);

  console.log(getAgeStudent);
});

结果我有一个带过滤学生的新数组。在您的情况下，您应该将变量中应返回的条件存储到方法中。

更新：我使用jQuery来更新解决方案。 JSFiddle exmaple

Javascript根据element.data过滤行
