3.7 判断

操作符：@equal->...

假设页面有如下元素，需要检查是否存在a.btn-primary的文本是：去充值，来识别是VIP章节：

<a href="//pay.yuewen.com/h5/index?appId=13&amp;areaId=31&amp;userGuid=854007784245&amp;returnUrl=http%3A%2F%2Fm.qidian.com%2Fbook%2Fchapter%3FbookId%3D1010868264%26chapterId%3D417931905%26from%3Dpay" class="btn-primary" data-size="14" data-eid="mqd_R32">去充值</a>

判断

"vip": "a.btn-primary@equal->去充值"
