我创建了一个 Web 应用程序，它的功能之一是列出与某个搜索匹配的产品。但是现在我希望能够在每个产品旁边有一个按钮，按下该按钮将打开一个具有更大图像和更多细节的模态框。我知道如何创建一个模式框并拥有一个成功运行的模式框。
我的问题是：我将如何动态创建按钮以便它显示在每个搜索结果旁边？每个按钮都必须不同。

var modal = document.getElementById('myModal');
// Get the button that opens the modal
var btn = document.getElementById("myBtn");

// When the user clicks the button, open the modal
btn.onclick = function() {
