使显示隐藏功能正常工作的问题
Issues getting a show hide function to work right
我有三个标题充当按钮。按钮 1、2 和 3。在页面加载时，我希望显示按钮 1 部分，但是如果有人单击按钮 2 或 3 以隐藏上一个按钮描述并让新按钮出现在其位置。
到目前为止，我无法让它工作。我在常规类中添加了display: none;，但正如我所说，我希望第一个在页面加载时显示。
我做错了什么？
$('#big-three-names').click(function() {
var thisDescription = $('.big-three-info', $(this));
$('.big-three-info').not(thisDescription).hide().parent().removeClass('closed');
thisDescription.slideToggle(500).parent().toggleClass('closed');
});.big-three {

</div>您可以使用 JQuery 执行以下操作。获取所选按钮的 html 文本并使用 JQuery .eq()显示div。
首先使用页面加载时$('.big-three-info').eq(0).css("display", "block");显示。
$('.big-three-names').click(function() {
var i = $( this ).html();
$('.big-three-info').css("display", "none")
$('.big-three-info').eq(i-1).css("display", "block");
});
$('.big-three-info').eq(0).css("display", "block");.big-three {
margin: 75px 7.5% 25px 7.5%;
height: 900px;
border: 1px solid black;
}
#big-three-title {
text-align: center;
font-size: 1.6em;
padding: 50px 0 30px 0;
}
#big-three-description {
text-align: center;
font-size: 1.3em;
}
#big-three-names-out {
width: 100%;
height: 75px;
margin: 50px 0;
}
.big-three-names {
display: inline-block;
border: 2px solid #FFF;
width: 33.05%;
height: 100%;
text-align: center;
font-size: 1.5em;
font-weight: bold;
background-color: #000;
color: #FFF;
cursor: pointer;
}
.big-three-names:hover {
background-color: blue;
color: #FFF;
}
.big-three-info {
margin: 50px 20%;
border: 1px solid black;
height: 550px;
display: none;
}
#big-three-info-title {
width: 100%;
margin: 100px 0 25px 50px;
font-size: 1.2em;
}
#big-three-info-description {
width: 100%;
margin-left: 50px;
font-size: 1em;
}
.show{
display:block;
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

</div>这是另一种解决方案
$('.big-three-info').eq(0).show();//show the first
$('.big-three-names').click(function() {
var index = $(this).index();//getting the index for button
$('.big-three-info').hide().eq(index).show();//first hide all then show the div with equal index
});

.JS
$('.big-three-names').click(function() {
$(".big-three-info").hide();
$("."+$(this).attr("class").split(" ")[1]+"-sub").show();
});
顺便说一下，big-three-names是你class的名字，而不是ID
