Question

我正在使用cmb2 taxonomy_multicheck_hierarchical字段类型以分层格式显示我的类别，但是我有很多术语，它们目前在分层结构中位于3个层次。

如果父项未选中，我想检查所有子项，如果父项未选中，则取消所有子项。

以下是我需要处理的呈现html的一部分：

<ul class="cmb2-checkbox-list cmb2-list">
  <li><input type="checkbox" class="cmb2-option" name="supplier_location[]" id="supplier_location1" value="england" data-hash="6u5db7f23u40"> <label for="supplier_location1">England</label></li>
  <li class="cmb2-indented-hierarchy">
    <ul>
      <li><input type="checkbox" class="cmb2-option" name="supplier_location[]" id="supplier_location2" value="east-midlands" data-hash="6u5db7f23u40"> <label for="supplier_location2">East Midlands</label></li>
      <li class="cmb2-indented-hierarchy">
        <ul>
          <li><input type="checkbox" class="cmb2-option" name="supplier_location[]" id="supplier_location3" value="derbyshire" data-hash="6u5db7f23u40"> <label for="supplier_location3">Derbyshire</label></li>
          <li><input type="checkbox" class="cmb2-option" name="supplier_location[]" id="supplier_location4" value="leicestershire" data-hash="6u5db7f23u40"> <label for="supplier_location4">Leicestershire</label></li>
          <li><input type="checkbox" class="cmb2-option" name="supplier_location[]" id="supplier_location5" value="lincolnshire" data-hash="6u5db7f23u40"> <label for="supplier_location5">Lincolnshire</label></li>
          <li><input type="checkbox" class="cmb2-option" name="supplier_location[]" id="supplier_location6" value="northhamptonshire" data-hash="6u5db7f23u40"> <label for="supplier_location6">Northhamptonshire</label></li>
          <li><input type="checkbox" class="cmb2-option" name="supplier_location[]" id="supplier_location7" value="rutland" data-hash="6u5db7f23u40"> <label for="supplier_location7">Rutland</label></li>
        </ul>
      </li>
      <li><input type="checkbox" class="cmb2-option" name="supplier_location[]" id="supplier_location8" value="east-of-england" data-hash="6u5db7f23u40"> <label for="supplier_location8">East of England</label></li>
      <li class="cmb2-indented-hierarchy">
        <ul>
          <li><input type="checkbox" class="cmb2-option" name="supplier_location[]" id="supplier_location9" value="bedfordshire" data-hash="6u5db7f23u40"> <label for="supplier_location9">Bedfordshire</label></li>
          <li><input type="checkbox" class="cmb2-option" name="supplier_location[]" id="supplier_location10" value="cambridgeshire" data-hash="6u5db7f23u40"> <label for="supplier_location10">Cambridgeshire</label></li>
          <li><input type="checkbox" class="cmb2-option" name="supplier_location[]" id="supplier_location11" value="essex" data-hash="6u5db7f23u40"> <label for="supplier_location11">Essex</label></li>
          <li><input type="checkbox" class="cmb2-option" name="supplier_location[]" id="supplier_location12" value="hertfordshire" data-hash="6u5db7f23u40"> <label for="supplier_location12">Hertfordshire</label></li>
          <li><input type="checkbox" class="cmb2-option" name="supplier_location[]" id="supplier_location13" value="norfolk" data-hash="6u5db7f23u40"> <label for="supplier_location13">Norfolk</label></li>
          <li><input type="checkbox" class="cmb2-option" name="supplier_location[]" id="supplier_location14" value="suffolk" data-hash="6u5db7f23u40"> <label for="supplier_location14">Suffolk</label></li>
        </ul>
      </li>
    </ul>
  </li>
  <li><input type="checkbox" class="cmb2-option" name="supplier_location[]" id="supplier_location15" value="scotland" data-hash="6u5db7f23u40"> <label for="supplier_location15">Scotland</label></li>
</ul>

我尝试的javascript代码如下：

jQuery( document ).ready(function( $ ) {

    $('#supplier_location_container input[type="checkbox"]').click(function(){
        $('input[type="checkbox"]', $(this).closest('li').next()).prop( 'checked', true );
    });

    $('#supplier_location_container input[type="checkbox"]:checked').click(function(){
        $('input[type="checkbox"]', $(this).closest('li').next()).prop( 'checked', false );
    });


});

但是我的代码包含许多错误！当我再次检查父级时，它也不允许我取消选中所有子级框；当您在层次结构的最上层中选中任何一个框时，它也会在同一级上直接选中它旁边的框！

更新：

我感觉自己正在进步，但是我还不安静。我的新代码允许我从父复选框中选中所有子复选框，但是，如果我尝试在层次结构的最后一个层次内选中任何复选框，它将始终直接在其下方选中该复选框。例如，如果您选中复选框ID Supplier_location3，它也会同时检查Supplier_location 4！

$('#supplier_location_container input[type="checkbox"]').click(function(){

        if($(this).is(':checked')){
            $('input[type="checkbox"]', $(this).closest('li').next()).prop( 'checked', true );
        }else{
            $('input[type="checkbox"]', $(this).closest('li').next()).prop( 'checked', false );
        }


    });

Answer 1

假设您的目标复选框都具有类cmb2-option，并且被认为是父级（或层次结构底层）的列表项不应该具有类cmb2-indented-hierarchy，并且应该选中/取消选中<li>兄弟姐妹中的子复选框（具有类cmb2-indented-hierarchy），我将通过以下方式实现该逻辑：

$('.cmb2-option').on('click', function(){
  //grab parent checkbox state
	const checkState = this.checked;
  //grab immediate sibling of parent <li> node
	const childListItem = $(this).closest('li:not(".cmb2-indented-hierarchy")').next('li.cmb2-indented-hierarchy');
  //exit if no child list available
	if(childListItem.length == 0) return;
  //iterate through child checkboxes and adjust their state according to parent
	[...childListItem.find('.cmb2-option')].forEach(childCheckbox => childCheckbox.checked = checkState);
});
