IE8中的Javascript/css
我遇到的问题是在IE中旋转图像(精确地说是时钟指针)。下面的脚本在一定程度上起作用(实际上正在进行动画),但它完全偏离轴旋转 我绝对不是Javascript/Jquery的天才,在IE8中如何正确地实现这一点时,我有点不知所措 代码如下:IE8中的Javascript/css,javascript,jquery,internet-explorer-8,Javascript,Jquery,Internet Explorer 8,我遇到的问题是在IE中旋转图像(精确地说是时钟指针)。下面的脚本在一定程度上起作用(实际上正在进行动画),但它完全偏离轴旋转 我绝对不是Javascript/Jquery的天才,在IE8中如何正确地实现这一点时,我有点不知所措 代码如下: (function(jQuery) { jQuery.fn.clock = function(options) { var defaults = { offset: '+0', type: 'analog' };
