javascript - 如何在此滑块/转盘的每个框下方添加不同的文本？

我想知道如何在此代码的每个框的底部添加新文本：

https://codepen.io/sub0-l3/pen/xjPwBP

我想明确地说，我不想在框内而是在框下输入新文本。每个框都有不同的文本。因此，基本上，当您按向左或向右箭头时，它将在框旁边显示新的下一个。谢谢！

最佳答案

有很多方法可以做到这一点（jQuery数据绑定，Vue.js，React.js），但是如果您想使用纯JavaScript的简单方法，就是这样：


为每个框设置ID，例如box1 box2 boxn ...
每个框都有其对应的card__text-content，其ID为databox1 databox2 ...
使用居中框显示或隐藏相应的card__text-content




showBoxData('box3');
function shiftLeft() {
    const boxes = document.querySelectorAll(".box");
    const tmpNode = boxes[0];
    boxes[0].className = "box move-out-from-left";

    setTimeout(function() {
        if (boxes.length > 5) {
            tmpNode.classList.add("box--hide");
            boxes[5].className = "box move-to-position5-from-left";
        }
        boxes[1].className = "box move-to-position1-from-left";
        boxes[2].className = "box move-to-position2-from-left";
        boxes[3].className = "box move-to-position3-from-left";
        boxes[4].className = "box move-to-position4-from-left";
        boxes[0].remove();

        document.querySelector(".cards__container").appendChild(tmpNode);

    }, 500);
    showBoxData(boxes[3].id);
}

function shiftRight() {
    const boxes = document.querySelectorAll(".box");
    boxes[4].className = "box move-out-from-right";

        }

        const tmpNode = boxes[noOfCards - 1];
        tmpNode.classList.remove("box--hide");
        boxes[noOfCards - 1].remove();
