使用jQuery从选项中筛选列中的数据

Question

我处理过滤，我有问题，我有4个选项输入，其中我有一些数据需要在表中过滤，现在我只为一个列过滤数据，但问题是如果我再添加一个过滤器，脚本将不能工作，并且过滤来自上一个选定值的数据。但我需要，如果我有2-4选择的值，在选项数据是过滤。

我的代码: JS：

$("#cancelFilters").hide();

$('#filterButton').click(function () {
    getSelectedVal()
    filterData()
    filters = [];
    $("#cancelFilters").fadeIn();
});

var filters = [];

function getSelectedVal() {
    var materialCode = $('#materialCode option:selected').text()
    var plantCode = $('#plantCode option:selected').text()
    var vsCode = $('#vsCode option:selected').text()
    var status = $('#statusCode option:selected').text()

    applyFilter(materialCode, 1)
    applyFilter(plantCode, 2)
    applyFilter(vsCode, 3)
    applyFilter(status, 4)
}

function applyFilter(value, id) {
    if (value)
        filters.push('.column' + id + ':contains(' + value + ')');
}


function filterData() {
    if (filters.length > 0) {
        var rows = $("#orderListData").find("tr").hide();

        filters.forEach(filter => {
            $("#orderListData td" + filter).parent().show();
        })

    }
}

$('#cancelFilters').click(function () {
    var $rows = $('#orderListData tr');
    $rows.show()
    $("#cancelFilters").fadeOut();
});

因此，如果在选项3中，u将选择023并点击add过滤器，它将工作，但是如果我选择023和选项4订好的，它将只过滤已预订的状态，问题在哪里？

Answer 1

通过对每个过滤器执行$("#orderListData td" + filter).parent().show()，您实际上显示了与其中一个筛选器匹配的每一行。同时，您只需要显示那些可以满足所有过滤器的行。

因此，与其循环遍历filters并检查是否有任何td元素满足它，不如循环遍历rows并检查它是否满足每个过滤器。

使用此代码进行此操作(只更改filterData函数)

​

    $("#cancelFilters").hide();

    $('#filterButton').click(function () {
      getSelectedVal()
      filterData()
      filters = [];
      $("#cancelFilters").fadeIn();
    });

    var filters = [];

    function getSelectedVal() {
      var materialCode = $('#materialCode option:selected').text()
      var plantCode = $('#plantCode option:selected').text()
      var vsCode = $('#vsCode option:selected').text()
      var status = $('#statusCode option:selected').text()

      applyFilter(materialCode, 1)
      applyFilter(plantCode, 2)
      applyFilter(vsCode, 3)
      applyFilter(status, 4)
    }

    function applyFilter(value, id) {
      if (value)
        filters.push('.column' + id + ':contains(' + value + ')');
    }


    function filterData() {
      if (filters.length > 0) {
        var rows = $("#orderListData").find("tr");
        rows.hide();
        
        //Check if any row satisfy all filters 
        $.each(rows, (i, row) => {
          if (filters.every(filter => $(row).find(filter).length)) {
            $(row).show();
          }
        })

      }
    }

    $('#cancelFilters').click(function () {
      var $rows = $('#orderListData tr');
      $rows.show()
      $("#cancelFilters").fadeOut();
    });

    .row {
      width: 100%;
      display: flex;
      flex-wrap: wrap;
    }

    .row::after {
      display: table;
      clear: both;
      content: "";
    }
