[英]How to center-zoom with responsive images without affecting the image size?
I put together a jquery and css function to zoom in and out of an image on mouseover, while keeping the constraining box size constant. 我将jquery和css函数放在一起,以在鼠标悬停时放大和缩小图像,同时保持约束框的大小不变。 I found this as an example, and edited more to what I would like. 我以这个为例,并对其进行了更多编辑。

Here is the code: 这是代码:
JS: JS:
$('.zoom img').on({
mouseover: function() {
var $scale = 1.5;
if (!$(this).data('w')) {
var $w = $(this).width();
var $h = $(this).height();
$(this).data('w', $w).data('h', $h);
}
$(this).stop(true).animate({
width: $(this).data('w') * $scale,
height: $(this).data('h') * $scale,
left: -$(this).data('w') * ($scale - 1) / 2,
top: -$(this).data('h') * ($scale - 1) / 2
}, 'fast');
},
mouseout: function() {
$(this).stop(true).animate({
width: $(this).data('w'),
height: $(this).data('h'),
left: 0,
top: 0
}, 'fast');
}
});

.zoom {
position: relative;
float: left;
margin: 30px 0 0 30px;
width: 400px;
height: 180px;
overflow: hidden;
border: 1px solid #000;
}
img {
position: absolute;
width: 400px;
height: 180px;
}

<div class="zoom">

</div>
It works great with a fixed image size, but my question is how do I expand it to responsive images? 它在固定图像大小的情况下效果很好,但是我的问题是如何将其扩展到响应图像? My webpage is based purely on responsiveness so I can't have a fixed css width or height anywhere because it would mess up different browser sizes. 我的网页纯粹基于响应能力,因此我无法在任何地方设置固定的CSS宽度或高度,因为它会弄乱不同的浏览器大小。 Is there anyway to do what I am trying to accomplish for responsive images, or without css? 无论如何,有没有要做我要为响应图像完成的工作,或者没有CSS?
The correct way to do this is to use transforms within css, this answer was due to a suggestion by the user @Keith. 正确的方法是在CSS中使用转换,此答案归因于用户@Keith的建议。 The example JS fiddle below will describe how to accomplish a zoomed-center look without affecting responsiveness. 下面的示例JS小提琴将描述如何在不影响响应性的情况下实现缩放中心外观。
