Animate display: none для отображения: inline

Question

Я пытаюсь создать веб-страницу с двумя различными наборами текста (текст A и текст B), которые имеют разную длину и не упорядочены по A/B (т.е. есть Текст A до и после текста B).

Наверху есть три кнопки: Show All, Text A и Text B.

Когда Show All нажата, весь текст отображаются, когда Text A нажата, только текст появится текст и текст B Текст скрыт и т.д.

Я хочу, чтобы анимировать изменение текста (с замиранием анимация).
Есть ли простой способ сделать это?

function select(name) { 
 
    var navbar = document.getElementById("navbar"); 
 
    var elems = navbar.getElementsByTagName("li"); 
 

 
    var classes = []; 
 

 
    for (x = 0; x < elems.length; x++) { 
 
    var obj = elems[x].getElementsByTagName("a")[0]; 
 
    obj.className = elems[x].id !== name ? "nav" : "navsel"; 
 
    classes[x] = elems[x].id; 
 
    } 
 

 
    for (n = 0; n < classes.length; n++) { 
 
    var allelems = document.getElementsByClassName(classes[n]); 
 
    for (x = 0; x < allelems.length; x++) { 
 
     var s = allelems[x].className; 
 
     if (s.search(name) >= 0 || name === "all") { 
 
     s = s.replace(" hide", ""); 
 
     } else if (s.search("hide") < 0) { 
 
     s += " hide"; 
 
     } 
 
     allelems[x].className = s; 
 
    } 
 
    } 
 
}

Это простое решение, которое не требует каких-либо библиотек, таких как JQuery.

Используя setTimeout, мы можем дать элементу стиль display:none только после того, как он исчезнет.

Answer 2

Я просто написал небольшой скрипт для вас, надеюсь, что это поможет вам в дальнейшем.

.content { 
 
    opacity: 0; 
 
    transition: opacity .75s ease-in-out; 
 
} 
 
.show { 
 
    opacity: 1; 
 
    transition: opacity .75s ease-in-out; 
 
}

<button class="article-a" onclick="document.getElementById('contentA').className = 'show';">Text A</button> 
 
<button class="article-b" onclick="document.getElementById('contentB').className = 'show';">Text B</button> 
 
<button class="article-all" onclick="document.getElementById('contentA').className = 'show';document.getElementById('contentB').className = 'show';">All Text</button> 
 

 
<div id="contentA" class="content">First part</div> 
 
<div id="contentB" class="content">Second Part</div>

Я считаю, что лучше использовать opacity для перехода, после непрозрачности устанавливается в 1, вы можете скрыть элемент.

Answer 3

Лично я бы справиться с этим путем присоединения FadeIn и FADEOUT метод JQuery для каждого класса текста всякий раз, когда он щелкнул. Вы можете сделать это, определив их в простом Javascript, что замирает один класс в, а других из и наоборот

$("#texta").click(function(){ 
    //Show texta and hide textb 
    $("#texta").fadeIn("slow"); 
    $("#textb").fadeOut("slow"); 
}); 

$("#textb").click(function(){ 
    //Show textb and hide texta 
    $("#textb").fadeIn("slow"); 
    $("#texta").fadeOut("slow"); 
}); 

$("#all").click(function(){ 
    //Show texta and hide textb 
    $("#texta").fadeIn("slow"); 
    $("#textb").fadeIn("slow"); 
});
