无法将 javascript 中的 bootstrap 弹出窗口添加到动态创建的元素

Question

我正在使用 javascript 在 HTML 中动态生成卡片数组，目前，当用户单击此按钮时，我会放入每个卡片按钮，他应该能够看到弹出窗口，但在此之前，我获取了一些数据以放在卡片上，但出现错误或丢失，弹出窗口没有出现，如果我评论了 loadPhotos() 的第一行，它就可以正常工作。

$(function () {
    $('[data-toggle="popover"]').popover()
})

const getAllPhotos = async () => {
    let res = await fetch('https://jsonplaceholder.typicode.com/photos').then(
        response => { return response.json() }
    )
    return res;
}

const displayPhotos = (photos) => {
    const view = document.getElementById('photosGrid');
    photos.forEach(element => {
        view.append(element)

    });
}
const createCard = (data) => {
    const card = document.createElement('div');
    card.classList.add('card', 'col-lg-2', 'm-2', 'p-0')
    const optionsButton = document.createElement('button')
    optionsButton.innerText = "test"
    optionsButton.title = "title of me"
    optionsButton.setAttribute('data-toggle', 'popover')
    optionsButton.setAttribute('data-content', 'content of me')
    card.appendChild(optionsButton)
    return card;
}
const createCardsArray = async (data) => {
    const res = await data.map(d => {
        return createCard(d);
    })
    return res;
}
const loadPhotos = async () => {
    const photos = await getAllPhotos();
    const cards = await createCardsArray([1, 2]);
    displayPhotos(cards);
}

loadPhotos();

创建元素后初始化popover，如果后面添加更多元素，可以重新初始化popover。

JQuery 在初始化期间将弹出窗口添加到元素，因此初始化后创建的元素不会由 JQuery

分配其弹出窗口
