我的代码存在问题
我正在尝试默认显示1 div( show_1 )然后隐藏它并在单击按钮2时显示第二个div( show_2 )。然后,当点击按钮1时,隐藏 show_2 并再次显示 show_1
https://jsfiddle.net/mgzurjgL/4/
虽然没有用,但当我点击任一按钮时没有任何反应。
function switch_div(show_1, show_2) {
var a = document.getElementById(show_1);
var a2 = document.getElementById(show_2);
if (a.style.display == 'block') {
a.style.display = 'block';
a2.style.display = 'none';
} else {
a.style.display = 'none';
a2.style.display = 'block';
}
}
.button {
width: 100px;
height: 30px;
display: inline-block;
background-color: black;
margin: 0 10px 10px 0;
color: #fff;
text-align: center;
line-height: 30px;
cursor: pointer;
}
.button:hover {
background-color: red;
}
.content {
width: 400px;
height: 100px;
display: block;
background-color: gray;
}
.hide {
display: none;
}
<div class="button" onclick="switch_div('show_1', 'show_2');">
1
</div>
<div class="button" onclick="switch_div('show_1', 'show_2');">
2
</div>
<div class="content" id="show_1">
Show by default (and when button 1 is clicked)
</div>
<div class="content hide" id="show_2">
Show this div when button 2 is clicked
</div>

两个项目:脚本放置和拼写错误。 JSFiddle的工作版本,在Google Chrome中测试过。
脚本必须在divs
之前运行。在JSFiddle Javascript设置中,我将“Load Type”更改为“No wrap-in <head>
”。这样,switch_div
函数在加载div
时就存在了。
有一个错字:
if (a.style.display == 'block')
应该是
if (a.style.display == 'none')
否则,您要在已经block
:)的元素上设置block
显示。
编辑:此代码仍然无法显示您想要的内容,因为无论按下哪个按钮,您编写的功能都会切换div
可见性。你真正想要的是this fiddle:
<div class="button" onclick="switch_div('show_1', 'show_2', true);">
和
<div class="button" onclick="switch_div('show_1', 'show_2', false);">
与
一起function switch_div(show_1, show_2, should_show_1) {
var a = document.getElementById(show_1);
var a2 = document.getElementById(show_2);
if(should_show_1) {
a.style.display = 'block';
a2.style.display = 'none';
}
else {
a.style.display = 'none';
a2.style.display = 'block';
}
}
这样你只能得到你想要的div
。

您在JSFiddle中设置错误,您需要在头部运行脚本而不是onload。你也传递了两次相同的参数。也是为什么你不尝试这样简单的东西。
https://jsfiddle.net/mgzurjgL/5/
function switch_div(show) {
document.getElementById("show_"+show).style.display = "block";
document.getElementById("show_"+((show==1)?2:1)).style.display = "none";
}
.button {
width: 100px;
height: 30px;
display: inline-block;
background-color: black;
margin: 0 10px 10px 0;
color: #fff;
text-align: center;
line-height: 30px;
cursor: pointer;
}
.button:hover {
background-color: red;
}
.content {
width: 400px;
height: 100px;
display: block;
background-color: gray;
}
.hide {
display: none;
}
<div class="button" onclick="switch_div(1);">
1
</div>
<div class="button" onclick="switch_div(2);">
2
</div>
<div class="content" id="show_1">
Show by default (and when button 1 is clicked)
</div>
<div class="content hide" id="show_2">
Show this div when button 2 is clicked
</div>

您需要在if-else中切换语句,或者将if中的条件更改为&#34; if(a.style.display!==&#39; block&#39;)&#34;
当a.style.display是&#39; block&#39;然后你必须把它设置为“没有”#39;隐藏它。
function switch_div(show_1, show_2) {
var a = document.getElementById(show_1);
var a2 = document.getElementById(show_2);
if (a.style.display !== 'block') {
a.style.display = 'block';
a2.style.display = 'none';
} else {
a.style.display = 'none';
a2.style.display = 'block';
}
}

我更改了js功能和按钮的“调用”。
function switch_div(show_1, show_2) {
var a = document.getElementById(show_2);
var a2 = document.getElementById(show_1);
a.style.display = 'none';
a2.style.display = 'block';
}
.button {
width: 100px;
height: 30px;
display: inline-block;
background-color: black;
margin: 0 10px 10px 0;
color: #fff;
text-align: center;
line-height: 30px;
cursor: pointer;
}
.button:hover {
background-color: red;
}
.content {
width: 400px;
height: 100px;
display: block;
background-color: gray;
}
.hide {
display: none;
}
<div class="button" onclick="switch_div('show_1', 'show_2');">
1
</div>
<div class="button" onclick="switch_div('show_2', 'show_1');">
2
</div>
<div class="content" id="show_1">
Show by default (and when button 1 is clicked)
</div>
<div class="content hide" id="show_2">
Show this div when button 2 is clicked
</div>

这也适用于:
<div class="button" onclick="switch_div(1,2);">
1
</div>
<div class="button" onclick="switch_div(2,1);">
2
</div>
<div class="content" id="show_1">
Show by default (and when button 1 is clicked)
</div>
<div class="content hide" id="show_2">
Show this div when button 2 is clicked
</div>
<script>
function switch_div(n1,n2) {
document.getElementById("show_"+n1).style.display = 'block';
document.getElementById("show_"+n2).style.display = 'none';
}
</script>
