我想使用按钮单击更改 div 的内容,在另一次单击中我想将旧内容带回 div 我正在使用按钮的图像...
我的 div 代码如下
<div class="pic-container" style="position:absolute; left: 3px; top: 102px;">
<div class="pic-row" >
<img src="images/A.Png" />
<img src="images/B.Png" />
<img src="images/C.Png" />
<img src="images/D.Png" />
<img src="images/E.Png" />
<img src="images/F.Png" />
<img src="images/G.Png" />
<img src="images/H.Png" />
<img src="images/I.Png" />
<img src="images/J.Png" />
<img src="images/K.Png" />
<img src="images/L.Png" />
<img src="images/M.Png" />
<img src="images/N.Png" />
<img src="images/O.Png" />
<img src="images/P.Png" />
<img src="images/Q.Png" />
<img src="images/R.Png" />
<img src="images/S.Png" />
<img src="images/T.Png" />
<img src="images/U.Png" />
<img src="images/V.Png" />
<img src="images/W.Png" />
<img src="images/X.Png" />
<img src="images/Y.Png" />
<img src="images/Z.Png" />
</div>
</div>
<img style="position:absolute; left: 272.5px; top: 647px; width: 171px; height: 122.5px;" src="images/Btn_Lower.png" id="image1" />
