I am trying to sort post-titles alphabetically using jQuery but nothing happens when I click on the sort filter (I might have wrong syntax). By default the All filter displays all of the posts I have currently. What would be the best and cleanest way to implement this? Thanks!
(Edited, I added some code that kmoser mentioned below)
$(document).ready(function () {
$(".filter-item").click(function () {
const value = $(this).attr("data-filter");
if (value == "all") {
$(".post-box").show("1000");
let html = $('.post-box').sort(
(a, b) => {
return (
$(a).attr('data-id')
>
$(b).attr('data-id')
)
}
)
$('.post.container').html(html)
} else if (value == "sort") {
let html = $('.post-box').sort(
(a, b) => {
return (
$(a).find('.post-title').text().trim().localeCompare(
$(b).find('.post-title').text().trim()
)
)
}
)
$('.post.container').html(html)
// Or to sort by date:
} else if (value == "sort-date") {
let html = $('.post-box').sort(
(a, b) => {
return (
Date.parse(
$(a).find('.post-date').text().trim()
)
>
Date.parse(
$(b).find('.post-date').text().trim()
)
)
}
)
$('.post.container').html(html)
}
});
$(".filter-item").click(function () {
$(this).addClass("active-filter").siblings().removeClass("active-filter");
});
});
// Header BackGround Change On Scroll
let header = document.querySelector("header");
window.addEventListener("scroll", () => {
header.classList.toggle("shadow", window.scrollY > 0);
});

I updated your code.
I think the mistake is when you want to display the result, and the date comparison I think could've been better, so I update the condition:
<!-- Sort Filter -->
<body>
<div class="post-filter container">
<span class="filter-item active-filter" data-filter="all">All</span>
<span class="filter-item" data-filter="sort">Sort by Alphabetically</span>
<span class="filter-item" data-filter="sort-date">Sort by Date</span>
</div>
<!-- Posts -->
<section class="post container">
<div class="post-box" data-id="1">
<img src="img/post-1.jpg" alt="" class="post-img" />
<a href="post-page.html" class="post-title"> C TEST </a>
<span class="post-date">2021-11-01</span>
<p class="post-decription">Lorem ipsum dolor</p>

<div class="post-box" data-id="2">

<a href="post-page.html" class="post-title"> B TEST </a>
