在 html (java servlet) 中单击了哪个列表元素

Question

The problem is shown in the title. Here's the code:

<div class=\"column-left\">
    <ul class=\"nav nav-list\">     
            <li tabindex=\"1\"><a href=\"BuyerSelectionPage\"><i class=\"icon-leaf\"></i> Ortaggi</a></li>
            <li tabindex=\"2\"><a href=\"BuyerSelectionPage\"><i class=\"icon-leaf\"></i> Verdure</a></li>
            <li tabindex=\"3\"><a href=\"BuyerSelectionPage\"><i class=\"icon-leaf\"></i> Formaggi</a></li>
            <li tabindex=\"4\"><a href=\"BuyerSelectionPage\"><i class=\"icon-leaf\"></i> Frutta</a></li>
            <li tabindex=\"5\"><a href=\"BuyerSelectionPage\"><i class=\"icon-leaf\"></i> Semi</a></li>
            <li tabindex=\"6\"><a href=\"BuyerSelectionPage\"><i class=\"icon-leaf\"></i> Succhi</a></li>
            <li tabindex=\"7\"><a href=\"BuyerSelectionPage\"><i class=\"icon-leaf\"></i> Piante</a></li>
            <li tabindex=\"8\"><a href=\"BuyerSelectionPage\"><i class=\"icon-leaf\"></i> Erbe</a></li>
    </ul>
</div>

It's a cut & paste from java, so don't look the \\" instead of "

How can i catch it from a java servlet? Because i want to create dynamic pages querying a database instead of creating lots of static pages.

Answer 1

Add a parameter with href and check for value of this parameter using request.getParameter("sel")

Eg:

    <li tabindex=\"1\"><a href=\"BuyerSelectionPage?sel=1\"><i class=\"icon-leaf\"></i> Ortaggi</a></li>
    <li tabindex=\"2\"><a href=\"BuyerSelectionPage?sel=2\"><i class=\"icon-leaf\"></i> Verdure</a></li>
    <li tabindex=\"3\"><a href=\"BuyerSelectionPage?sel=3\"><i class=\"icon-leaf\"></i> Formaggi</a></li>
