您也可以使用属性选择器执行此操作:
int main(int argc, const char *argv[]) {
std::vector<int> rw{1, 0, 1, 1, 1, 0, 1, 1, 1, 0, 1, 1, 1, 1, 1, 1};
std::mutex m;
auto multithread_shuffle = [rw, &m]() mutable {
unsigned seed = std::chrono::system_clock::now().time_since_epoch().count();
std::shuffle (rw.begin(), rw.end(), std::default_random_engine(seed));
std::lock_guard lock(m);
for (size_t i = 0; i < rw.size(); i++) {
std::cout << "rw[" << i << "] = " << rw[i] << std::endl;
}
};
std::thread t1(multithread_shuffle);
std::thread t2(multithread_shuffle);
t1.join();
t2.join();
return 0;
}

.list-group-item[disabled] {
color:red;
}

你是对的。要选择已禁用的元素,请使用disabled
选择器:
:disabled {
css declarations;
}
