SVG的fill属性在Chrome中不起作用 [英] fill property of SVG does not working in Chrome
问题描述
问题是我无法在Chrome中的fill属性中设置值(颜色)，但在Firefox中它可以工作.我尝试了很多方法来做，但是没有结果.我看到的更改SVG图标颜色的唯一方法是通过更改下面的<symbol>的ID通过jQuery(或JavaScript).请帮我解决这个问题！
Trouble is that I can't set value (color) in fill property in Chrome, but in Firefox it works. I tried a lot ways to do it, but there is no result. The only way I see to change color of SVG icon is via jQuery (or JavaScript) by changing id of <symbol>, which is below. Please help me solve this problem!
这是我需要在Chrome中使用的功能:
This is what I need to work in Chrome:

推荐答案
最好在path fill属性中使用currentColor.
It's better if you use currentColor in your path fill attribute.
然后仅在需要时在svg符号容器中添加颜色.您应该删除span元素，无需添加它，这实际上对语义HTML不利.
Then just add a color in your svg symbol container when you need to. You should remove the span element, there's no need to add it, it's actually bad for semantic HTML.
.icon {
width: 30px;
height: 30px;
}
.icon--blue {
color: blue;
}
.icon--red {
color: red;
}
<svg width="0" height="0" style='display: none;' xmlns="http://www.w3.org/2000/svg">
