我得到了这个html代码:
<div class="imgContent">
<div id="galleryImg">
<img class="img_<?php echo $this->id ?>_1" width="1200" height="450" src="<?php echo $this->baseUrl('f/images/'.$this->image[1]) ?>" />
<?php if($this->image[4]){ ?>
<img class="img_<?php echo $this->id ?>_<?php echo $this->image[6] ?>" style="display:none" width="1200" height="450" src="<?php echo $this->baseUrl('f/images/'.$this->image[4]) ?>" />
<?php } ?>
<?php if($this->image[5]){ ?>
<img class="img_<?php echo $this->id ?>_<?php echo $this->image[7] ?>" style="display:none" width="1200" height="450" src="<?php echo $this->baseUrl('f/images/'.$this->image[5]) ?>" />
<?php } ?>
</div>
<a id="prev" href="javascript:void(0)"></a>
<a id="next" href="javascript:void(0)"></a>
</div>
我想在图像上悬停时从 png 文件中添加箭头。怎么做(点击时图像正在改变)
