javascript - What's wrong with this click event.

Question

I made a tab, and there was no problem when I used onmouseover, and the pictures were displayed normally.

But something went wrong when I used the onclick event. When the mouse clicked on the a label, the image flashed and disappeared.

Just a few simple sentences, I really don’t know what went wrong.
