翻转卡不会在第二个动画上保持后部div
Posted

篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了翻转卡不会在第二个动画上保持后部div相关的知识,希望对你有一定的参考价值。
我有一张卡片,其中包含以下动画:当您点击“编辑”按钮时:
- 它移动到屏幕的中心
- 移动时旋转180度(背面内容不同 - 空白)
在它到达div的中心并完成旋转后,卡会扩展到全屏(之后我重定向用户)。我的问题是,在第二个动画之后(实际上当完成所有动画时)只有后面的内容是可见的,在休息时,当它进行旋转和翻译时,它只是前面的内容翻转可见(请参阅JSFIDDLE向下)我的代码看起来喜欢:
html:
<div class="cards-holder">
<div class="card bg-light mb-3 item" style="display: none">
<div class="front face">
<div class="card-header kid-card-header">
<div class="kid-card-header-name">
<label>Child name: </label>
<label>Kevin </label>
</div>
<div class="kid-card-header-delete-button">
<i class="fa fa-trash-o deleteChild" aria-hidden="true" style="cursor: pointer" idOfChild="23"></i>
</div>
</div>
<div class="card-body">
<div class="kid-card-content">
<div class="kid-card-content-image">
//some image
</div>
<div class="kid-card-content-description">
<p class="card-text">
<label>Age: </label>
<label>2 years</label>
</p>
<p class="card-text">
<label>Gender: </label>
<label>Male</label>
</p>
<p class="card-text">
<label>Height: </label>
<label>50 cm</label>
</p>
<p class="card-text">
<label>Weight: </label>
<label>25 kg</label>
</p>
</div>
</div>
</div>
<div class="card-footer kid-card-footer">
<button class="btn btn-secondary editChildButton" ChildId="23">Edit</button>
</div>
</div>
<div class="back face">
</div>
</div>
</div>
CSS:
.card {
transform-style: preserve-3d;
}
.face {
position: absolute;
width: 100%;
height: 100%;
backface-visibility: hidden;
}
.face.back {
display: block;
transform: rotateY(180deg);
background-color: #78C2AD;
}
和JS:
$.fn.toggleZindex= function() {
const $this = $(this);
if($this.css("z-index")=="auto") {
$this.css("z-index", "99999");
}else {
$this.css("z-index", "auto");
}
return this;
};
$.fn.animateRotate = function(angle, duration, easing, startingDegree, complete) {
var args = $.speed(duration, easing, complete);
var step = args.step;
return this.each(function(i, e) {
args.complete = $.proxy(args.complete, e);
args.step = function(now) {
$.style(e, 'transform', 'rotateY(' + now + 'deg)');
if (step) return step.apply(e, arguments);
};
$({ deg: startingDegree}).animate({deg: angle}, args);
});
};
function getRotationDegrees(obj) {
const matrix = obj.css("-webkit-transform") ||
obj.css("-moz-transform") ||
obj.css("-ms-transform") ||
obj.css("-o-transform") ||
obj.css("transform");
if(matrix !== 'none') {
const values = matrix.split('(')[1].split(')')[0].split(',');
const a = values[0];
const b = values[1];
var angle = Math.round(Math.atan2(b, a) * (180/Math.PI));
} else { var angle = 0; }
return (angle < 0) ? angle + 360 : angle;
}
$('.editChildButton').on('click',
function () {
const idOfChild = $(this).attr('ChildId');
const tc = $(window).height() / 2 - $('.item').height() / 2 - $(this.closest('.item')).offset().top;
const lc = $(window).width() / 2 - $('.item').width() / 2 - $(this.closest('.item')).offset().left;
$(this.closest('.item')).toggleZindex();
const startingDegree = getRotationDegrees($(this.closest('.item')));
$(this.closest('.item')).animateRotate(startingDegree == 0 ? 180 : 0, 2000, 'swing', startingDegree);
$(this.closest('.item')).animate({
left: lc,
top: tc
}, 2000, function () {
$(this.closest('.item'))
.css({
position: 'fixed', left: $(this.closest('.item')).offset().left, top:
$(this.closest('.item')).offset().top
});
$(this.closest('.item')).animate({
left: 0,
top: 0,
width: '100vw',
height: '100vh'
}, 2000, function() {
window.location =
"/Children/EditChild?childId=" + idOfChild;
});
});
});
演示我的问题JSFIDDLE
基本上,我实际需要的是,从卡片旋转180度(从第一个动画)开始,在进行第二个动画时,只有空白的绿色背面可见。此外,在所有这些结束时,我需要重定向到另一个页面,所以我需要知道什么时候完成。
我更新了JDFIDDLE以显示我卡的实际位置。
答案
您可以通过用CSS动画替换JS动画来解决此问题(并节省大量性能)。
请参阅此参考:https://jsfiddle.net/g9wb4rwp/
$('.editChildButton').on('click', function () {
$('.flip-container').addClass('flip');
});
/* entire container, keeps perspective */
.flip-container {
perspective: 1000px;
}
.flip-container.flip .flipper {
transform: rotateY(180deg);
}
.front, .back {
width: 100%;
height: 480px;
}
/* flip speed goes here */
.flipper {
transition: 0.6s;
transform-style: preserve-3d;
position: relative;
}
/* hide back of pane during swap */
.front, .back {
backface-visibility: hidden;
position: absolute;
top: 0;
left: 0;
}
/* front pane, placed above back */
.front {
z-index: 2;
/* for firefox 31 */
transform: rotateY(0deg);
}
/* back, initially hidden pane */
.back {
transform: rotateY(180deg);
background: green;
