如何使用 Javascript 创建具有动态信息的模态？

Question

我知道这很简单，但我已经很累了，我似乎无法找到正确的关键字来在搜索引擎上找到解决方案......我正在构建一个简单的前端电子商务网站，我我已经设置了模态，但我需要它根据我单击的产品显示正确的信息......我该怎么做？

编辑：我没有输入代码的坏处......

例如，这是您的产品

<div onCLick="showModal(this)">
    <h3>Product Name</h3>
    <p>product description</p>
</div>

现在你需要javascript函数

function showModal(product) {
    // get the product information
    var productName = $(product).find("h3").text();
    var productDescription = $(product).find("p").text();

    var modal = $("#myModal");

    // fill the modal with the information
    $(modal).find(".modal-title").text(productName);
    $(modal).find(".modal-body").text(productDescription);

    // show the modal
    $("#myModal").modal("show");
}
