Javascript - 我无法创建我的灯箱，forEach 未定义

Question

I have a problem with my lightbox, when I'm trying to link my lightbox folder (lightbox.js) to the photographerPage (photographerPage.js line 56), it says that "forEach" is undefined, and I don't know why.

I don't know if someone can help me with that. Here is the code (GitHub Pages) : https://axsf3.github.io/FishEye/photographer-page.html?id=243

Thanks in advance.

Answer 1

Based on your code, it sounds like this.medias is not an array, which would cause forEach to be undefined, as that method is specific to the Array datatype.

I'd recommend doing console.log(this.medias) to see what this.medias is giving back and what the current shape of the data is.
