在 jQuery 中旋转 Div 元素 [英] Rotating a Div Element in jQuery

问题描述

试图旋转一个 div 元素...这可能是对 DOM 的亵渎，它可以与 canvas 元素一起工作吗?我不确定 - 如果有人对这如何工作或为什么不工作有任何想法，我很想知道.谢谢.

解决方案

旋转 DIV 使用 WebkitTransform/-moz-transform:rotate(Xdeg).

这在 IE 中不起作用.Raphael 库确实适用于 IE，并且它可以旋转.我相信它使用 canvases

如果要为旋转设置动画，可以使用递归setTimeout()

您甚至可以使用 jQuery 的 .animate()

确保考虑元素的宽度.如果旋转宽度大于其可见内容的宽度，您将获得有趣的结果.但是，您可以缩小元素的宽度，然后然后旋转它们.

这是一个简单的 jQuery 片段，用于旋转 jQuery 对象中的元素.可以开始和停止旋转:

$(function() {var $elie = $(selectorForElementsToRotate);旋转(0)；函数旋转(度){//对于 webkit 浏览器:例如铬合金$elie.css({ WebkitTransform: 'rotate(' + degree + 'deg)'});//对于 Mozilla 浏览器:例如火狐$elie.css({ '-moz-transform': 'rotate(' + degree + 'deg)'});//使用递归调用动画旋转setTimeout(function() {rotate(++degree); },5);}});

jsFiddle 示例

注意:
取度数并增加它，将顺时针旋转图像.降低旋转度将旋转图像逆时针.

Trying to rotate a div element...This might be DOM blasphemy, could it work possibly with a canvas element? I'm not sure - if anybody has any ideas of how this could work or why it doesn't, I'd love to know. Thanks.

解决方案

To rotate a DIV Make use of WebkitTransform / -moz-transform: rotate(Xdeg).

This will not work in IE. The Raphael library does work with IE and it does rotation. I believe it uses canvases

If you want to animate the rotation, you can use a recursive setTimeout()

You could probably even do part of a spin with jQuery's .animate()

Make sure that you consider the width of your element. If rotate an that has a larger width than its visible content, you'll get funny results. However you can narrow the widths of elements, and then rotate them.

Here is a simply jQuery snippet that rotates the elements in a jQuery object. Rotatation can be started and stopped:

$(function() {
    var $elie = $(selectorForElementsToRotate);
    rotate(0);
    function rotate(degree) {

          // For webkit browsers: e.g. Chrome
        $elie.css({ WebkitTransform: 'rotate(' + degree + 'deg)'});
          // For Mozilla browser: e.g. Firefox
        $elie.css({ '-moz-transform': 'rotate(' + degree + 'deg)'});

          // Animate rotation with a recursive call
        setTimeout(function() { rotate(++degree); },5);
    }
});

jsFiddle example

Note:
Taking the degree and increasing it, will rotate the image clockwise. Decreasing the degree of rotation will rotate the image counter clockwise.
