我要尝试做的是，如果特定div组中的div与主体类ID号（例如，）具有相同的类ID号（例如，“。post-123”-ID号是“ 123”）。 postid-123'），然后向该div添加一个具有相同ID号的新类。在我的代码中，所有内容似乎都运行正确，只是它没有在组中的所有div之间循环-只是将新类追加到组中的第一个div上。jQuery / JS：<script>jQuery(document).ready(function($) { var current_post_id = get_current_post_id(); var current_project_id = get_current_project_id(); function get_current_post_id() { var body_class = $('body.single-project'); var post_id = ''; if(body_class) { var classList = body_class.attr('class').split(/\s+/); $.each(classList, function(index, item) { if (item.indexOf('postid') >= 0) { var item_arr = item.split('-'); post_id = item_arr[item_arr.length -1]; return false; } }); } return post_id; } function get_current_project_id() { var project = $('.et_pb_portfolio .et_pb_portfolio_item'); var project_id = ''; if(project) { var classList = project.attr('class').split(/\s+/); $.each(classList, function(index, item) { if (item.indexOf('post') >= 0) { var item_arr = item.split('-'); project_id = item_arr[item_arr.length -1]; return false; } }); } return project_id; } if (current_post_id == current_project_id) { $('.et_pb_portfolio #post-' + current_project_id).addClass('current-project'); } console.log('project id is: ' + current_project_id); console.log('page id is: ' + current_post_id);});</script>

这是执行此操作的一种更简单的原始方法。
const getCurrentProjectId = () => {
let postId = Array.from(document.querySelector('body').classList).find(cls => cls.indexOf('postid-') > -1).split('-')[1];
return `post-${postId}`;
}
console.log(getCurrentProjectId());
document.addEventListener('DOMContentLoaded', () => {
let currentProject = getCurrentProjectId();
document.querySelectorAll('.project').forEach(proj => {
if(proj.classList.contains(currentProject)) proj.classList.add('current-project');
});
});
.current-project {
border: 2px solid red;
}

这是使用find的选项（假设只有一个帖子）：
const getCurrentProjectId = () => `post-${Array.from(document.querySelector('body')
.classList)
.find(cls => cls.indexOf('postid-') > -1)
.split('-')[1]}`;
console.log(getCurrentProjectId());
document.addEventListener('DOMContentLoaded', () => {
let currentProject = getCurrentProjectId();
Array.from(document.querySelectorAll('.project'))
.find(proj => proj.classList.contains(currentProject)) .classList.add('current-project');
});
.current-project {
border: 2px solid red;
}

这是一个考虑到BenM对ID的评论的选项
const getCurrentProjectId = () => `post-${Array.from(document.querySelector('body')
.classList)
.find(cls => cls.indexOf('postid-') > -1)
.split('-')[1]}`;
console.log(getCurrentProjectId());
document.addEventListener('DOMContentLoaded', () => {
document.querySelector(`#${getCurrentProjectId()}`).classList.add('current-project');
});
.current-project {
border: 2px solid red;

为什么您需要遍历所有div元素才能做到这一点？
由于ID属性应该始终是唯一的，因此您可以从body类中提取ID ，然后选择相关元素：
if( $('body').hasClass('single-project') )
{
var postID = /(postid-)[0-9]+/gm.exec($('body').attr('class'))[0].replace('postid-', '');
$('#post-' + postID).addClass('current-project');
}
