搜索关键词的情况,
点击标题后跳转到的是个菠菜游戏网站,

<div class="aw-comment-upload-img-list active">
<a href="http://ask.seowhy.com/uploads/questions/20161125/ec1687ad67fa3f67e5ce0073a5b237c4.png" target="_blank" data-fancybox-group="thumb" rel="lightbox"><img src="http://ask.seowhy.com/uploads/questions/20161125/ec1687ad67fa3f67e5ce0073a5b237c4.png" class="img-polaroid" title="" alt="" /></a>

点击快照后确实不一样的模板内容:

<div class="aw-comment-upload-img-list active">

</div>

点击快照后的源码情况:

<div class="aw-comment-upload-img-list active">
<a href="http://ask.seowhy.com/uploads/questions/20161125/55202b2d803f537c44c3da3f626a5c23.png" target="_blank" data-fancybox-group="thumb" rel="lightbox"><img src="http://ask.seowhy.com/uploads/questions/20161125/55202b2d803f537c44c3da3f626a5c23.png" class="img-polaroid" title="" alt="" /></a>
