当我按下按钮时，我确实让模态工作并显示。但是，现在(不确定我是怎么做到的)我无法打开模式框。

我将我的页面布局为图像，然后图像下方的按钮用于打开模式。

这是我的 HTML...

我不确定为什么突然间它不允许我打开模式。

请帮忙!

谢谢玛丽

最佳答案

如我所见，在 JS 代码中，您试图以错误的方式获取按钮。getElementById 在这种情况下将不起作用，因为您的按钮没有 id 属性

也许尝试像这样捕获按钮:document.querySelector(".headbutton");

让我知道它是否解决了问题。

有关querySelector 的更多信息，请参阅 this link另见 this link对于querySelectorAll
