Question

好吧，伙计们！我目前正在尝试用几个svgs来改变多个类的填充颜色。我没有得到想要的结果。我将在下面显示我的代码。

这是Javascript

<script>
function secondary(color)
{
document.getElementsByClassName("secon").style.fill = color;
}
</script>

以下是其中一个按钮的样子：D

<label>
<input type="radio" id="42" name="45" mandatory="1" 
onClick="secondary('#0066ff'); myFunction('A Vibrant Blue');" />
<img src="/pictures/Color Tiles/CunningBlue.png" alt="Cunning Blue"
border="0" /><span class="textcolor">Cunning Blue</span></div>
</label>

最后这里是SVG GOODIES＆lt; 3

非常感谢有关此主题的任何帮助。

Answer 1

getElementsByClassName会返回包含该类的数组元素。

因此，您必须遍历该数组，在每个元素上设置样式。

function secondary(color) {
    var elements = document.getElementsByClassName("secon");
    for (var i = 0; i < elements.length; i++)
        elements[i].style.fill = color;
}

我快速测试了here，这解决了这个问题。
