[英]Zoom In Image (JavaScript)
我有宝丽来照片库图像样式。 但是我想要的是单击图像时,它将放大或放大图像。
我不知道如何在我的else
语句上实现它。 我单击图像时尝试翻转它,它的工作方式如下:
.photo.flipped .side-front {
-webkit-transform: rotateY(-180deg);
-moz-transform: rotateY(-180deg);
-ms-transform: rotateY(-180deg);
transform: rotateY(-180deg);
}
.photo.flipped .side-back {
-webkit-transform: rotateY(0);
-moz-transform: rotateY(0);
-ms-transform: rotateY(0);
transform: rotateY(0);
}
JavaScript :
item.addEventListener('click', function () {
if ((currentData != dataSize[item.id]) || (currentData == null)) {
select(dataSize[item.id]);
shuffleAll();
} else {
/*Paul Zoom In Photo*/
item.classList.contains('zoomed') === true ? item.classList.remove('zoomed') : item.classList.add('zoomed');
/*END*/
}
});
这是我的CSS :
body {
background-color: #F2EBE2;
}
.fullscreen {
width: 100%;
height: 100%;
overflow: hidden;
margin: 0;
padding: 0;
}
.photo {
position: absolute;
cursor: pointer;
-webkit-transition: all 0.6s;
-moz-transition: all 0.6s;
transition: all 0.6s;
}
.side {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
-webkit-backface-visibility: hidden;
-moz-backface-visibility: hidden;
backface-visibility: hidden;
-webkit-transition: transform 0.6s;
-moz-transition: transform 0.6s;
transition: transform 0.6s;
}
.side-back {
-webkit-transform: rotateY(-180deg);
-moz-transform: rotateY(-180deg);
-ms-transform: rotateY(-180deg);
transform: rotateY(-180deg);
display: table;
}
.side-back div {
display: table-cell;
vertical-align: middle;
background-color: rgb(0, 0, 0);
}
.side-back p {
padding: 2px;
color: #d7551d;
font-family: Helvetica, Arial, sans-serif;
}
figure {
width: 150px;
position: absolute;
/* padding: 30px; */
margin: 0 auto;
text-align: center;
background-color: rgb(10, 10, 10);
}
figure img {
height: auto;
max-width: 100%;
margin: 0 auto;
/*margin-bottom: 15px;*/
}
figure img.zoomed{
position: fixed;
top: 5vh;
bottom: 5vh;
left: 5vw;
right: 5vw;
max-width: 90vw;
max-height: 90vh;
margin: auto;
border: 4px solid #000
}
figure figcaption {
font-family: Comic Sans, Comic Sans MS, cursive;
color: #f85a16;
font-size: 10px;
}
.navbar {
position: fixed;
bottom: 0;
width: 100%;
padding: 10px;
text-align: center;
background-color: black;
z-index: 999;
}
button {
background-color: transparent;
padding: 10px 24px;
color: #ffffff;
border: 2px solid black;
-webkit-transition-duration: 0.4s;
-moz-transition-duration: 0.4s;
transition-duration: 0.4s;
}
button:hover {
background-color: #a00;
color: white;
}
#copyright {
font-family: Consolas, Verdana, Arial, sans-serif;
position: fixed;
color: #ccc;
text-decoration: none;
bottom: 20px;
right: 10px;
}
#copyright:hover {
color: white;
text-decoration: none;
}
@media screen and (max-width: 767px) {
#forkme {
display: none;
}
#copyright {
position: relative;
display: block;
text-align: center;
right: 0px;
bottom: 0px;
}
}
如上所述,一种方法是使用transform: scale(2);
另一个简单的方法是:
document.querySelector('img.sample-image').addEventListener('click', function() { this.classList.toggle('sample-image-large'); });
.sample-image { transition:all 1s ease; width: 100%; } .sample-image-large { width: 200% !important; }
