我试图获得以下效果:
bootstrap 4
张卡显示为网格button
时,它应animate
,如下所示:
旋转180度,达到特定的高度/宽度(从400px到350px到整个屏幕),并将自己定位在屏幕中央。目前,我知道如何使用
进行轮换rotateY(180deg)
当我点击按钮时:
$('#enlarge').on('click',
function() {
$('#kidCard').toggleClass("flipper");
});
在鳍状肢类中设置了旋转,但是我无法获得剩余的所需动画。 有人可以帮我这个吗?
更新:
我当前的HTML:
<div class="flip-container">
<div class="card text-white bg-primary mb-3 kid-card" id="kidCard">
<div class="card-header">
Child name: ...
<i class="fa fa-trash-o" aria-hidden="true" style="cursor: pointer"></i>
</div>
<div class="card-body kid-card-content">
<div class="kid-card-content-image">
<img src="~/Content/download.png" width="110" height="110"/>
</div>
<div class="kid-card-content-description">
<p class="card-text">
Age: ...
</p>
<p class="card-text">
Gender: ...
</p>
<p class="card-text">
Height: ...
</p>
<p class="card-text">
Weight: ...
</p>
</div>
</div>
<div class="card-footer">
<button class="btn btn-secondary" id="enlarge">Edit</button>
</div>
</div>
</div>
拥有js文件:
$('#enlarge').on('click',
function() {
$('#kidCard').toggleClass("flipper");
});
现在,这是我的css文件:
.flip-container .flipper {
transform: rotateY(180deg);
}
.flipper {
transition: 2s;
transform-style: preserve-3d;
position: relative;
}
在变换中,我还尝试了translateY(calc(50vh - 50%)) translateX(calc(50vh - 50%))
,以便将其放置在屏幕的中央,但它无法正常工作。
SOLUTION:
我终于使用了以下代码(感谢大家的贡献):
.js文件:
$.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);
});
});

我不知道您的具体情况,但如果您能找到使用position: absolute
的方法,那么在移动卡片时会更容易。
将div放置在屏幕中央时,重要的是要了解转换时元素的宽度和高度。如果您的用例允许您手动设置这些尺寸然后设置,您只需使用:
left: calc(50% - manuallySetWidth);
top: calc(50% - manuallySetHeight);
但如果您无法手动设置它们,则需要找到备用机制。说实话,我在这里提出的变体是使用a somewhat new addition to CSS的东西(这就是为什么它很可能还有其他更简单的解决方案)和here is apost帮助我开始使用这些。

一种可能的方法是在你的鳍状肢类上设置width
,然后将边距设置为自动。设置width
值和margin:auto
将使块级元素居中。
.flip-container .flipper {
transform: rotateY(180deg);
}
.flipper {
transition: 2s;
margin: auto;
width:400px;
height:400px;
transform-style: preserve-3d;
position: relative;
}
或者如果你更喜欢这样的弹性盒解决方案:
.flip-container .flipper {
transform: rotateY(180deg);
}
.flipper {
transition: 2s;
transform-style: preserve-3d;
position: relative;
width:400px;
height:400px;
}
.body-flipper {
display:flex;
justify-content: center;
}
body, html{
width:100% !important;
height: 100% !important;
margin:0;
}

在我看来,要达到这样的效果,CSS动画是不够的。最简单的方法是将定位更改为固定,将卡放在中间并根据需要进行缩放。看看DEMO。
当然这只是一个例子,只有一张牌,但它应该适用于不同位置的多张牌。在点击卡上:
动画可以双向运作。
HTML:
<div class="flip-container">
<div class="card text-white bg-primary mb-3 kid-card" id="kidCard">
<div class="card-header">
Child name: ...
<i class="fa fa-trash-o" aria-hidden="true" style="cursor: pointer"></i>
</div>
<div class="card-body kid-card-content">
<div class="kid-card-content-image">
<img src="~/Content/download.png" width="110" height="110"/>
</div>
<div class="kid-card-content-description">
<p class="card-text">
Age: ...
</p>
<p class="card-text">
Gender: ...
</p>
<p class="card-text">
Height: ...
</p>
<p class="card-text">
Weight: ...
</p>
</div>
</div>
<div class="card-footer">
<button class="btn btn-secondary" id="enlarge">Edit</button>
</div>
</div>
</div>
CSS:
.flip-container {
width: 400px;
}
.flip-container .flipper {
transform: rotateY(180deg);
}
.card {
transition-duration: 2s;
}
.movement {
transform: translate(-50%,-50%) rotateY(180deg);
}
JS:
var element = $('#kidCard');
var w = element.width();
var h = element.height();
$('#enlarge').on('click',
function() {
if(element.hasClass('movement')) {
element.removeClass('movement');
element.css({width: w, height: h, top: 0, left: 0});
} else {
var left = element.offset().left;
var top = element.offset().top;
element.css({position: 'fixed', left: left, top: top, width: w, height: h});
element.addClass('movement');
element.css({width: '100vw', height: '100vh', top: '50%', left: '50%'});
}
});
