如何通过单击按钮来突出显示输入按钮?

Question

我不能编写jquery javascript代码，因此我不知道如何突出显示(边框或背景更改)提交按钮几秒钟。我尝试了一些在这个平台上分享的脚本，但我并不幸运。你建议用什么代码?

我需要高亮显示的按钮是submitbtn

和需要通过点击突出显示它的按钮是eventbtn

感谢你的帮助

感谢编辑:我想添加类提交按钮一旦按钮被点击

.sidebar {
background-color: black;
width: 33%;
float: right;
}
.submitbtn {
width: 66%;
position: relative;
float: left;
background-color: #407060;
padding: 15px 30px;
border: none;
cursor: pointer;
color: white;
text-transform: uppercase;
}
.eventbtn {
color: white;
border: none;
border-radius: 2px;
padding: 15px 30px;
width: 100%;
background-color: #A73D42;
cursor: pointer;
}
body {
background-color: #f1f1f1
}

<p><input type="submit" value="Submit" class="submitbtn" id="form-submit" /></p>
<div class="sidebar">
<button class="eventbtn" id="highlight"> <<<<<<<<<<< </button>
</div>

Answer 1

关键是在几秒钟后删除高亮显示，这可以用setTimeout()函数完成:

function highlight(id)
{
clearTimeout(highlight.timer);
const el = document.getElementById(id);
//highlight the button
el.classList.add("highlighted");
//remove highlight after 3sec
highlight.timer = setTimeout(() => el.classList.remove("highlighted"), 3000);
}

.sidebar {
background-color: black;
width: 33%;
float: right;
}
.wpcf7-form-control.has-spinner.wpcf7-submit {
width: 66%;
position: relative;
float: left;
background-color: #407060;
padding: 15px 30px;
border: none;
cursor: pointer;
color: white;
text-transform: uppercase;
}
.eventbtn {
color: white;
border: none;
border-radius: 2px;
padding: 15px 30px;
width: 100%;
background-color: #A73D42;
cursor: pointer;
}
body {
background-color: #f1f1f1
}
/* added */
.highlighted
{
box-shadow: 0 0 2em 1px red;
}
.wpcf7-submit {
transition: box-shadow 0.2s;
}

<p><input type="submit" value="Submit" class="wpcf7-form-control has-spinner wpcf7-submit" id="form-submit" /></p>
<div class="sidebar">
<button class="eventbtn" id="highlight" onclick="highlight('form-submit')"> <<<<<<<<<<< </button>
</div>

您的意思是点击eventbtn时高亮显示submitbtn吗?

添加一个js来处理点击事件，然后在submitbtn中添加高亮类

var eventbtn = document.getElementById('highlight');
var submitbtn = document.getElementsByClassName('submitbtn')[0];
eventbtn.addEventListener('mousedown', function () {
submitbtn.classList.add('highlight');
});
eventbtn.addEventListener('mouseup', function () {
submitbtn.classList.remove('highlight');
});

.sidebar {
background-color: black;
width: 33%;
float: right;
}
.submitbtn {
width: 66%;
position: relative;
float: left;
background-color: #407060;
padding: 15px 30px;
border: none;
cursor: pointer;
color: white;
text-transform: uppercase;
}
.eventbtn {
color: white;
border: none;
border-radius: 2px;
padding: 15px 30px;
width: 100%;
background-color: #A73D42;
cursor: pointer;
}
.highlight {
background-color: #8beccc;
}
body {
background-color: #f1f1f1
}

<p><input type="submit" value="Submit" class="submitbtn" id="form-submit" /></p>
<div class="sidebar">
<button class="eventbtn" id="highlight"> <<<<<<<<<<< </button>
</div>

只需在要突出显示的元素中添加一个类。然后用setTimeout函数删除类。

1. 在CSS中添加一个高专用性的类，它包含所有你想要应用的可见更改。不管它是什么。可以是背景，边框，框影…
2. 在JS中使用eventListener来监听按钮上的点击事件。
3. 应用类指定CSSclassList.add()。
4. 增加setTimeout功能，使用classList.remove()在指定时间后删除类

香草JavaScript:

// button element that will be clicked
var button = document.querySelector('button[class="eventbtn"]'),
// element that should be highlighted
input = document.querySelector('#form-submit'),
// timer in ms
timer = 2000;
// eventListener to execute the script on button click
button.addEventListener('click', function() {
// adds a class to apply CSS changes for the highlighting
input.classList.add('highlight');
// timeout function
setTimeout(function() {
// removes the class after the timer has been reached
input.classList.remove('highlight');
}, timer);
})

#form-submit.highlight {
background-color: yellow;
}
/* original CSS */
.sidebar {
background-color: black;
width: 33%;
float: right;
}
.wpcf7-form-control.has-spinner.wpcf7-submit {
width: 66%;
position: relative;
float: left;
background-color: #407060;
padding: 15px 30px;
border: none;
cursor: pointer;
color: white;
text-transform: uppercase;
}
.eventbtn {
color: white;
border: none;
border-radius: 2px;
padding: 15px 30px;
width: 100%;
background-color: #A73D42;
cursor: pointer;
}
body {
background-color: #f1f1f1
}

<p><input type="submit" value="Submit" class="wpcf7-form-control has-spinner wpcf7-submit" id="form-submit" /></p>
<div class="sidebar">
<button class="eventbtn" id="highlight">&#60;&#60;&#60;&#60;&#60;&#60;&#60;&#60;&#60;&#60;&#60;</button>
</div>

jQuery:

// button element that will be clicked
var $button = $('button[class="eventbtn"]'),
// element that should be highlighted
$input = $('#form-submit'),
// timer in ms
timer = 2000;
//Eventlistener looking for a click event
$button.click(function() {
//adds a class for highlighting
$input.addClass('highlight');
//timeout function
setTimeout(function() {
//removes class for highlighting
$input.removeClass('highlight');
}, timer);
})

#form-submit.highlight {
background-color: yellow;
}
/* original CSS */
.sidebar {
background-color: black;
width: 33%;
float: right;
}
.wpcf7-form-control.has-spinner.wpcf7-submit {
width: 66%;
position: relative;
float: left;
background-color: #407060;
padding: 15px 30px;
border: none;
cursor: pointer;
color: white;
text-transform: uppercase;
}
.eventbtn {
color: white;
border: none;
border-radius: 2px;
padding: 15px 30px;
width: 100%;
background-color: #A73D42;
cursor: pointer;
}
body {
background-color: #f1f1f1
}

我试图通过使用animation和keyframes来回答纯css。我的尝试只在第一次有效，每次更改目标后都有效。

(注意，我不习惯这些属性，所以可能有更好的方法)

#form-submit{
background-color: transparent;
}
@keyframes changeBackground {
0% {
background-color: orange;
}
99.999% {
background-color: orange;
}
100% {
background-color: transparent;
}
}
#form-submit:target{
animation: changeBackground 1s;
}

<input type="submit" value="submit" id="form-submit" />
<a href="#form-submit">highlight</a>
<br>
<a href="#">change target</a>
