sng中的png/base64中的图片在Safari中不显示

我在svg中嵌入了一个图像，并试图在Safari中绘制它。虽然它在Firefox中正常工作，但图像不会在Safari中显示。代码很简单，并显示在下面。现在奇怪的是，当我把这段代码放到一个在线测试站点（http://www.rapidtables.com/web/tools/svg-viewer-editor.htm）时，它在Safari中正常工作......但是无论我把代码放在我的网页中，它都不起作用。？可能是与页面其余部分的不良交互，无法弄清楚在哪里。sng中的png/base64中的图片在Safari中不显示

如果有人有建议，非常欢迎。

顺便说一下，我试图使用Blockly作为项目，并生成此图像并将其包含在Blockly SVG中。我几乎成功地将一名编辑加入Blockly集团。

它不会在Chrome的工作，要么。

问题是你的base64编码是错误的。删除这两个在数据URI的末尾等号：

感谢您的建议，但我加了两个=标志，以确保字符的base64数目将是整除4（听说这是Safari中的问题）。事实上，如果我删除它们，至少在我的配置上它也不起作用。 – user3047221

@ user3047221 =符号不应该在那里，2050不能被4整除。 –

实际上，问题在于我没有使用setAttribute和其他JS函数的NameSpaced版本。解决了，感谢您的期待。 – user3047221
