jQuery旋转图像并相应地调整父元素 [英] Jquery rotate image and adjust the parent element accordingly

问题描述

我正在使用css旋转来旋转图像.它工作正常，但未同时调整其他元素. 它与其他元素重叠.我想要的是如果我旋转图像，则它不应与其他元素重叠，而应相应地调整其高度和宽度. 请在下面查看我的代码

I am using css rotate to rotate an image. It is working fine but it is not adjusting other elements as well. It is overlapping other elements. What I want if i rotate an image then it shouldn't overlap the other elements but adjust its height and width accordingly. Please see my code below

HTML

<div id="wrapper">
<h1>Heading 1</h1>
<img id="testimg" src="http://thecutestblogontheblock.com/wp-content/uploads/2012/10/Owl-Walk-free-cute-halloween-fall-blog-BANNER.png" alt="" />

</div>
<button>Rotate</button>

JQuery

var degrees = 0;
$("button").click(function(){
    degrees += 90;
        var img = $("#testimg");
        img.css({
            "-webkit-transform": "rotate(" + degrees + "deg)",
            "-moz-transform": "rotate(" + degrees + "deg)",
            "transform": "rotate(" + degrees + "deg)" /* For modern browsers(CSS3)  */
        });
});

推荐答案

它不会自动发生，但是您可以使用getBoundingClientRect()告诉您转换后的整体高度和宽度，并使用其调整大小您的包装器(或其他元素)以适应/适应更改:

It won't happen automatically, but you can use getBoundingClientRect() to tell you what the overall height and width is after the transformation, and use that to resize your wrapper (or other elements) to fit/accommodate the change:

var angle = 0;
$(function () {
    $("button").click(function () {
        angle = (angle + 30) % 360;

        var bounds = $("img#testimg").css({
            "transform-origin": "50% 50%",
            "transform": "rotate("+angle+"deg)",
        })[0].getBoundingClientRect();

        $("#wrapper").css({
            width: bounds.width,
            height: bounds.height
        });
    });
});
