    <p>I am trying to screen scrape a web page (using Mechanize) which displays the records in a grid page wise. I am able to read the values displayed in the first page but now need to navigate to the next page to read appropriate values.</p> <pre><code>&lt;tr&gt; &lt;td&gt;&lt;span&gt;1&lt;/span&gt;&lt;/td&gt; &lt;td&gt;&lt;a href="javascript:__doPostBack('gvw_offices','Page$2')"&gt;2&lt;/a&gt;&lt;/td&gt; &lt;td&gt;&lt;a href="javascript:__doPostBack('gvw_offices','Page$3')" &gt;3&lt;/a&gt;&lt;/td&gt; &lt;td&gt;&lt;a href="javascript:__doPostBack('gvw_offices','Page$4')" &gt;4&lt;/a&gt;&lt;/td&gt; &lt;td&gt;&lt;a href="javascript:__doPostBack('gvw_offices','Page$5')" &gt;5&lt;/a&gt;&lt;/td&gt; &lt;td&gt;&lt;a href="javascript:__doPostBack('gvw_offices','Page$6')"&gt;6&lt;/a&gt;&lt;/td&gt; &lt;td&gt;&lt;a href="javascript:__doPostBack('gvw_offices','Page$7')" &gt;7&lt;/a&gt;&lt;/td&gt; &lt;td&gt;&lt;a href="javascript:__doPostBack('gvw_offices','Page$8')"&gt;8&lt;/a&gt;&lt;/td&gt; &lt;td&gt;&lt;a href="javascript:__doPostBack('gvw_offices','Page$9')" &gt;9&lt;/a&gt;&lt;/td&gt; &lt;td&gt;&lt;a href="javascript:__doPostBack('gvw_offices','Page$10')" &gt;10&lt;/a&gt;&lt;/td&gt; &lt;td&gt;&lt;a href="javascript:__doPostBack('gvw_offices','Page$11')"&gt;...&lt;/a&gt;&lt;/td&gt; &lt;/tr&gt; </code></pre> <p>I am able to get through all the links but when I try this:-</p> <pre><code>links = (row/"a") links.each do |link| agent.click link.attributes['href'] # This fails agent.click link # This also fails end </code></pre> <p>Reason is that agent.click expects the URL as an argument.</p> <p>Is there a way where we can read all the values when they are displayed page wise ? If not how can we have such a click action when the href is a postback and not a URL??</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
