根据下拉选项过滤表行

Question

我正在编写一个脚本，它将根据一些Bootstrap下拉列表过滤表。我想避免使用臭名昭着的datatables脚本的大小和复杂性。

下面，我目前的脚本状态看起来并不理想，因为我必须制作几个循环才能实现过滤。

我的两个主要问题：

1. 很高兴性能和效率：我使用最好的方法来做到这一点吗？
2. 错误：如果添加过滤器，则可以正常工作，但删除过滤器会导致相关项目隐藏（而不是显示更多项目）。

如果他们改进脚本，我愿意使用以下内容：

1. :contains
2. Array.prototype.filter
3. 有点牵强但放弃Vue.js将是一个选项，因为我可以在我项目的其他地方使用它的数据绑定功能。
4. 任何lodash方法

let data = []
let filters = {
  company: [],
  location: []
}

let $tableRows = $('table tbody tr');

$tableRows.each(function (i, element) {
  data.push($(element).data())
})

$('.js-filter').on('click', function () {
  $(this).toggleClass('on')
  $('.selection').toggleClass('hidden glyphicon glyphicon-chevron-down')
  $('.dropdown-toggle').toggleClass('disabled')
  // $tableRows.removeClass('hidden')
})

$(document).on('click', '.dropdown-menu a', function (e) {
  e.stopPropagation()
  let filterData = $(this).data()

  if ($(this).hasClass('active')) {
    $(this).removeClass('active glyphicon glyphicon-ok')
    prepareFilters(filterData)
    filterRow(data, filters)
  } else {
    $(this).addClass('active glyphicon glyphicon-ok')
    prepareFilters(filterData)
    filterRow(data, filters)
  }
})

function prepareFilters (filterData) {
  Object.keys(filterData).forEach(function (key) {
    let filterIndex = filters[key].indexOf(filterData[key])
    if (filterIndex === -1) {
      filters[key].push(filterData[key])
    } else {
      filters[key].splice(filterIndex, 1)
    }
  })
}

function filterRow (data) {
  data.forEach(function(value, index) {
    Object.keys(value).some(function (key) {
      if (key !== 'id') {
        console.log(key)
        console.log(filters[key])
        if (filters[key].indexOf(value[key]) === -1) {
          $(`[data-id="${value.id}"]`).addClass('hidden')
        } else {
          $(`[data-id="${value.id}"]`).removeClass('hidden')
          console.log(`item with id ${value.id} should be invisible`)
          return true
        }
      }
    })
  })
