svg 更改路径在 Firefox 和 Safari 中不起作用

svg change path not working in Firefox and Safari

我的网页中有一些 SVG,我想在点击时对其进行动画处理,因此我编写了以下代码,但它仅适用于 Google Chrome,不适用于 Firefox 或 Safari。

我的代码:

    $('#menu').click(function () {

        if ($(this).find('path:nth-child(1)').attr('d') === 'M12.972944,50.936147C12.972944,50.936147,51.027056,12.882035,51.027056,12.882035') {
            $(this).find('path:nth-child(1)').attr('d','M5.0916789,18.818994C5.0916789,18.818994,52.908321,18.818994,52.908321,18.818994');
            $(this).find('path:nth-child(2)').show('fast');
            $(this).find('path:nth-child(3)').attr('d','M5.0916788,44.95698C5.0916788,44.95698,52.908321,44.95698,52.908321,44.95698');
        }
        else {
            $(this).find('path:nth-child(1)').attr('d','M12.972944,50.936147C12.972944,50.936147,51.027056,12.882035,51.027056,12.882035');
            $(this).find('path:nth-child(2)').hide('fast');
            $(this).find('path:nth-child(3)').attr('d','M12.972944,12.882035000000002C12.972944,12.882035000000002,51.027056,50.936147,51.027056,50.936147');
        }

    });
*{

}

您没有解释 "Not working" 的意思。我猜你的意思是 transitions 不起作用?

目前只有 Chrome 支持在 d 属性上应用 CSS 动画和过渡。

这是因为 d 不是样式 属性。 SVG 1.1 规范声明只有一组已定义的属性可以使用 CSS 设置样式。这些属性的列表在此处的 SVG 规范中:

https://www.w3.org/TR/SVG/propidx.html

即将推出的 SVG2 规范将使大多数 SVG 属性可通过 CSS 设置样式。到那时,希望所有浏览器都支持 CSS 动画。但是,截至目前,只有 Chrome 开始实施此更改。
