当使用jquery甚至纯JavaScript选中3个或更多复选框时,如何过滤div列表?

基于我之前的question,我想基于特定div元素的存在,通过不同组合过滤div列表。

在下面的示例中,我使用3个复选框“卡”,“贝宝”,“仅显示开放式商店”来过滤列表。现在,它适用于“卡”和“ Paypal”复选框,但是如果您还尝试选中“仅显示开放商店”复选框,则会使其混乱。我该如何解决?

代码如下:

var checkboxArea = document.querySelector('.filter-area')
var storeBlocks = Array.from(document.querySelectorAll('.store-block'))
var byCard = document.getElementById('by-card')
var byPaypal = document.getElementById('by-paypal')
var byOpen = document.getElementById('by-open')

var cardBlocks = storeBlocks.filter(function(block) {
  return block.querySelector('.card-available')
})

var payPalBlocks = storeBlocks.filter(function(block) {
  return block.querySelector('.paypal-available')
})

var openStoreBlocks = storeBlocks.filter(function(block) {
  return block.querySelector('.close-small-tag')
})

checkboxArea.addEventListener('change', function(e) {
  switch (true) {
    case byCard.checked && byPaypal.checked:
      storeBlocks.forEach(function(block) {
        block.classList.remove('hide-me')
      })
      break
    case byCard.checked:
      cardBlocks.forEach(function(block) {
        block.classList.remove('hide-me')
      })
      payPalBlocks.forEach(function(block) {
        block.classList.add('hide-me')
      })
      break
    case byPaypal.checked:
      cardBlocks.forEach(function(block) {
        block.classList.add('hide-me')
      })
      payPalBlocks.forEach(function(block) {
        block.classList.remove('hide-me')
      })
      break

    case byOpen.checked:
      openStoreBlocks.forEach(function(block) {
        block.classList.toggle('hide-me')
      })
      break



    default:
      payPalBlocks.concat(cardBlocks).forEach(function(block) {
        block.classList.remove('hide-me')
      })
  }
})
