Navigating to ScienceDirect's NextPage using scrapy

Using Scrapy, how to navigate to "nextpage" link, from any results page generate by sciencedirect.com?

The nextpage link is the input element:

<div class="paginationBar">
<span style="color:#A4A4A4;" aria-disabled="true" alt="Previous Page" title="Previous Page"><< Previous</span>
<span class="pageText">Page 1 of 20462</span>
<input class="nextPrev" type="submit" title="Next Page" alt="Next Page" name="bottomNext" onmouseout="this. className='nextPrev'" onmouseover="this.className='nextPrevHov'" value="Next >>">
</div>

And exists some javascript but I dont know how to take it :(
