    <p>I'm not entirely sure if this is possible, but I'll ask here. </p> <p>I have a .jsp page that populates the dropdown contents from .txt files and loaded using jquery/javascript. </p> <p>They're loaded like this: </p> <pre><code>$function(){ $(".dropdownA").load("dropdowninfo.txt); }; </code></pre> <p>I also use a servlet to ping the database to fill out the other information for this particular .jsp page. My question is how to select the proper value of what's in the dropdown menu to show that value. </p> <p>For example:<br> if the dropdown contained {a, b, c, d, e} and the servlet returned "d", how can i get the jsp page to show the "d". Currently it will show the list. Below is how I coded the jsp page. </p> <pre><code>&lt;select class=".dropdownA"&gt;&lt;select&gt; </code></pre> <p>This will display a, b, c, d, e in the dropdown. So how would you preselect "d"? Or should i just do it all from the servlet, including populating the dropdown?</p> <p>Thanks!</p> <p><strong>Update:</strong></p> <p>The servlet runs a query, and returns the results to the jsp page. For example:</p> <pre><code>ResultsSet results = record.executeQuery(); Result result = ResultSupport.toResult(results); request.setAttribute("result", result); RequestDispatcher rd = request.getRequestDispacher("/page.jsp"); rd.forward(request, response); </code></pre> <p>So on the jsp page, I get the corresponding value by calling:<br> c:out value="${result[x]}"</p> <p>In essence, somehow i need to put ${result[x]} as the preselected value of the select list. </p>

    1. COHow is the value coming back? As HTML? JSON?

    3. COPerhaps I should re-phrase that: what is sent back to the browser? "${value[x]}" is not sent to the browser, that's your server-side code.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
