问题描述
这似乎应该有效,但却没有。我不确定问题出在哪里 - 我做错了,或者我可能有语法错误。我什么都没做。我正试图在点击按钮时更改当前图片。我是Javascript的初学者,所以请保持温和;)谢谢!
This seems like it should work but doesn't. I'm not sure where the problem is - either I'm doing it wrong, or it's possible I have a syntax error. I just doesn't do anything. I'm trying to get the current picture to change when the button is clicked. I'm a beginner at Javascript, so please be gentle ;) Thank you!
