我正在創建與父子項和子子項的層次關系串列，如果我選中父項，然后選中所有子項，但我單擊子項，則將檢查子子項。一切正常，但它在第二次點擊時的作業在第一次點擊時不起作用。這是我的小提琴示例。小提琴鏈接在這里http://jsfiddle.net/fahadsheikh/qdkwy0s7/8/
function changeCategoryStatus(_this, id) {
var main = document.querySelector(".main-checkbox" id);
var children = document.querySelectorAll(".sub-checkbox" id);
function toggleCheck() {
var array=[];
children.forEach(child => {
if($(this).prop("checked") == true){
child.checked = child.checked = true
}
else if($(this).prop("checked") == false){
child.checked = child.checked = false
}
array.push(child.value);
})
return array;
}
if(main){
main.addEventListener("click", toggleCheck);
}
//for sub-parent category
var sub_parent = document.querySelector(".sub-parent" id);
var sub_children = document.querySelectorAll(".sub-checkbox" id);
function toggleCheck() {
var array=[];
sub_children.forEach(child => {
if($(this).prop("checked") == true){
child.checked = child.checked = true
}
else if($(this).prop("checked") == false){
child.checked = child.checked = false
}
array.push(child.value);
})
return array;
}
if(sub_parent){
sub_parent.addEventListener("click", toggleCheck);
}
var status = $(_this).prop('checked') == true ? 'active' : 'inactive';

uj5u.com熱心網友回復：
您當前邏輯的主要問題是每次單擊toggleCheck()復選框時都將函式附加到主復選框。這會導致您看到的奇怪行為。
另請注意，您的 HTML 無效。li元素必須是孩子們ul唯一的，不能div和ul本身不能成為另一個孩子ul。您需要正確構建嵌套串列。您還可以通過洗掉增量 id 和 class 屬性來改進 HTML。它們是一種反模式，會導致不必要的復雜代碼。使用 DOM 遍歷來關聯元素。
關于 JS 代碼，您應該避免使用行內onclick事件處理程式，因為它們不再是好的做法。使用通過 JS 邏輯添加的不顯眼的事件處理程式。您還toggleCheck()多次重新定義該函式，這是一種很大的代碼味道。
綜上所述，HTML 和 JS 可以大大簡化：
$('.sortable :checkbox').on('change', e => {
let $cb = $(e.target);
let isChecked = $cb.prop('checked');
$cb.closest('li').find(':checkbox').prop('checked', isChecked);
/*
// AJAX commented out for this demo only
$.ajax({
type: 'POST',
url: "{{url('admin/categories-status')}}",
data: {
id: $cb.prop('id'),
status: isChecked ? 'active' : 'inactive',
_token: "{{ csrf_token() }}"
},
success: function(result) {
$("#status-success").html(result.success).show();
setTimeout(function() {
$("#status-success").hide();
}, 3000);
}
});
