如何翻转具有特定方向的图像

Question

我还是编码新手，请善待我:)

无论如何 我有 2 个信用卡输入文本。 当我单击 CVV 输入文本时，它应该是水平向左翻转，就像到期年输入文本应该水平向右翻转一样。 我的问题是我不知道如何为这张卡设置特定的翻转方向。

<input type="text" Placeholder="Expiration Year" onclick="flip()" />
<input type="text" placeholder="cvv" onclick="flip()" />
<section class="container">
<div class="card">
<div class="front">1</div>
<div class="back">2</div>
</div>
</section>

.container {
width: 200px;
height: 260px;
position: relative;
border: 1px solid #ccc;
-webkit-perspective: 800px;
-moz-perspective: 800px;
-o-perspective: 800px;
perspective: 800px;
}
.card {
width: 100%;
height: 100%;
position: absolute;
-webkit-transition: -webkit-transform 1s;
-moz-transition: -moz-transform 1s;
-o-transition: -o-transform 1s;
transition: transform 1s;
-webkit-transform-style: preserve-3d;
-moz-transform-style: preserve-3d;
-o-transform-style: preserve-3d;
transform-style: preserve-3d;
-webkit-transform-origin: 50% 50%;
}
.card div {
display: block;
height: 100%;
width: 100%;
line-height: 260px;
color: white;
text-align: center;
font-weight: bold;
font-size: 140px;
position: absolute;
-webkit-backface-visibility: hidden;
-moz-backface-visibility: hidden;
-o-backface-visibility: hidden;
backface-visibility: hidden;
}
.card .front {
background: red;
}
.card .back {
background: blue;
-webkit-transform: rotateY(180deg);
-moz-transform: rotateY(180deg);
-o-transform: rotateY(180deg);
transform: rotateY(180deg);
}
.card.flipped {
-webkit-transform: rotateY(180deg);
-moz-transform: rotateY(180deg);
-o-transform: rotateY(180deg);
transform: rotateY(180deg);
}

function flip() {
$('.card').toggleClass('flipped');
}

我将用半代码编写这个来解释这个想法。

//pass the id of the element you want to flip    
function flip(idToFlip){    
if(!$('#idToFlip').hasClass('flipped')){
$('#idToFlip').addClass('flipped');
//this function can check the state of other elements and place them in the correct state - you will have to write this yourself if needed
cleanUpOtherElements();
}
}
//bind this function to a focus-out/blur event to flip it back
function flipBack(idToFlipBack){
//see above, it's almost the same
}

编写这样的东西可以防止您可能遇到的双击错误，并确保元素在不应该翻转时不会保持翻转状态。
