javascript – 创建一个多选下拉列表,用于过滤DataTable

2023年8月20日 166次阅读

我有一个DataTable和一个外部多选按钮组.我需要的是,如果用户选择/取消选择此列表中的复选框,DataTable可以实时过滤表格(无需点击“提交”按钮),但我不知道.我有一个选择工作,但从未使用多选.

单选代码
HTML

<label for="groupDD">
    Groups
</label>
<select id="groupDD" name="groupDD" class="form-control">
    <option value="AllGroups">All groups</option>
    <option value="Accessories">Accessories</option>
    <option value="Broadband">Broadband</option>
    <option value="BroadbandAncillary">Broadband ancillary</option>
    <option value="Cables">Cables</option>
    <option value="Custom Services">Customer services</option>
</select>

JQuery的

$('#groupDD').on('change', function (e) {
    e.preventDefault();

    if ($(this).val() == 'AllGroups') {
        $('#reportDataTable').DataTable().column(2).search('').draw();
    } else {
        $('#reportDataTable').DataTable().column(2).search($(this).val()).draw();
    }
})

div class="btn-group">
    <button type="button" class="btn btn-default dropdown-toggle"
        data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" style="height: 35px">
        Group name &nbsp;
        <span class="caret"></span>

《javascript – 创建一个多选下拉列表,用于过滤DataTable》
JQuery Fucntion调用代码需要去的地方

// Filters report from the dropdown list
$("input[name = 'filterReportDD'], label[name = 'filterReportDD']").click(function () {
    event.stopPropagation();

})

不知道怎么做,我假设它需要某种循环,可能会构建一个数组,然后记住选择的选项,并保持重绘表不知道

最佳答案 这是从下拉列表到DataTable执行多选过滤器的代码

$('input[name=filterReportDD]').click(function() {
    if ($(this).is(":checked")) {
        groupNameFilterApplied.push($(this).val());
    }

    $('#reportDataTable').DataTable().column(2).search(groupNameFilterApplied.join('|'), true, false, true).draw();
});
