如何在 EJS 的 for 循环中操作特定的 div?
How to manipulate specific div inside a for-loop of EJS?
我在谷歌上搜索了好几个小时,我想在 onClick 事件期间更改一个元素的 svg 颜色,结果它要么为 for 循环中的所有元素设置样式,要么只为第一个元素设置样式。我在这里添加了我的 ejs 和 toggleSvg() js 脚本。希望你能帮助我。

toggleSvg() js:
<script>
function toggleSvg() {
svgElem = document.getElementById("test");
if(svgElem.style.fill === 'red'){
svgElem.style.fill = 'none';
}else{
svgElem.style.fill = 'red';
}
}
</script>
您正在循环使用 id
只能 select 一个元素,如果你想为所有 svg 着色,你可以使用 class
,如果你想为特定 svg 着色,你可以这样做
onclick="toggleSvg(this)"
这样你在点击时传递当前元素
<script>
function toggleSvg(svgElem ) {
if(svgElem.style.fill === 'red'){
svgElem.style.fill = 'none';
}else{
svgElem.style.fill = 'red';
}
}
</script>
