单击列表组时,我需要选择的下一个(以下)列表组,并将其更改为data-state = enabled .list-group,并从每个列表组项目中删除类disabled

我的代码越来越复杂,我想知道
1)如何使计数器正常工作,以免计数器因增加太多而出错
2)如何不使用jQuery简化此
3)如何使用jQuery简化此

JS
var listGroup = document.querySelectorAll('#selectPatientCategories .list-group');
//console.log(listGroup);
var cats = document.querySelectorAll('a.list-group-item');
//console.log(cats);
var counter = 1;
// For each category list item
var catIndex = 0, catLength = cats.length;
for (; catIndex < catLength; catIndex++) {
var thiscat = cats[catIndex];
//console.log(listGroupIndex);
// Click function on list item
thiscat.addEventListener('click', function () {
//console.log(thisListGroup);
//Get the parent .list-group
thisListGroup = this.parentElement;
thisListGroupCats = thisListGroup.querySelectorAll('a.list-group-item');
//console.log(thisListGroupCats);
// For each category .list-group-item within this listGroup
var listGroupIndex = 0, listGroupCatsLength = thisListGroupCats.length;
for (; listGroupIndex < listGroupCatsLength; listGroupIndex++) {
// Focus on just this .list-group being iterated
rmThisCat = thisListGroupCats[listGroupIndex];
rmThisCat.classList.remove('active');
}
// Activate the clicked .list-group-item
this.classList.add('active');
// Activate the next list group
nextListGroup = listGroup[counter];
nextListGroup.setAttribute('data-state', 'enabled');
nextListGroupCats = nextListGroup.querySelectorAll('a.list-group-item');
nextCatIndex = 0;
console.log(nextListGroupCats);
for (; nextCatIndex < nextListGroupCats.length; nextCatIndex++) {
var nextCat = nextListGroupCats[nextCatIndex];
nextCat.classList.remove('disabled');
}
// increment the counter
counter++;
}); // End click function
}
最佳答案
这是解决方案。同样,这是jquery的实现。您可以根据需要将逻辑转换为纯js。
$(document).on("click",".list-group a[class='list-group-item']",function()
{
alert();
var listGroup = $(this).parent();
if (listGroup.attr("data-state") !== "disabled")
{
$(listGroup).find("a").removeClass("active");
$(this).addClass("active");
var nextListGroup =
listGroup.parent().next().find("div");
$(nextListGroup).attr("data-state","");
$(nextListGroup).find("a").removeClass("disabled");
}
});

使用不同的选择器方法:
$(".list-group a[class^='list-group-item']").click(function()
{
var listGroup = $(this).parent();
if (listGroup.attr("data-state") !== "disabled")
{
$(listGroup).find("a").removeClass("active");
$(this).addClass("active");
var nextListGroup =
listGroup.parent().next().find("div");
$(nextListGroup).attr("data-state","");
$(nextListGroup).find("a").removeClass("disabled");
}
});
