    copied!<p>You should <strong><em>always</em></strong> use an HTML <code>&lt;form&gt;</code> element - even (and especially) if you're using AJAX. It will be more usable, accessible, and will make your life as a developer easier. Do a Google search for "ajax graceful degradation" or "accessible ajax" if you don't believe me; it's actually pretty easy.</p> <p>For example, here's an AJAX form that degrades gracefully using <a href="http://jquery.com/" rel="nofollow">jQuery</a>, the greatest JavaScript library on earth:</p> <pre><code>&lt;form method="post" action="ajax/test.html" name="ajax-form" id="ajax-form"&gt; &lt;fieldset&gt; &lt;legend&gt;Form name&lt;/legend&gt; &lt;p&gt;&lt;label for="username"&gt;Username: &lt;input type="text" name="username" id="username" value="" /&gt;&lt;/label&gt;&lt;/p&gt; &lt;p&gt;&lt;label for="password"&gt;Password: &lt;input type="password" name="password" id="password" value="" /&gt;&lt;/label&gt;&lt;/p&gt; &lt;p&gt; &lt;label for="option-a"&gt;Option A: &lt;input type="radio" name="options" id="option-a" value="a" /&gt;&lt;/label&gt;&lt;br/&gt; &lt;label for="option-b"&gt;Option B: &lt;input type="radio" name="options" id="option-b" value="b" /&gt;&lt;/label&gt;&lt;br/&gt; &lt;label for="option-c"&gt;Option C: &lt;input type="radio" name="options" id="option-c" value="c" /&gt;&lt;/label&gt; &lt;/p&gt; &lt;p&gt; &lt;label for="select-box"&gt;Select Box: &lt;select name="select-box" id="select-box" size="1"&gt; &lt;option value="1"&gt;1&lt;/option&gt; &lt;option value="2"&gt;2&lt;/option&gt; &lt;option value="3"&gt;3&lt;/option&gt; &lt;/select&gt; &lt;/label&gt; &lt;/p&gt; &lt;p class="buttons"&gt;&lt;button type="submit"&gt;Submit&lt;/button&gt; &lt;button type="reset"&gt;Reset&lt;/button&gt;&lt;/p&gt; &lt;/fieldset&gt; &lt;/form&gt; &lt;script type="text/javascript"&gt; $().ready(function() { var $ajaxForm = $('#ajax-form'); // Create container to store ajax result $ajaxForm.find('.buttons').after($('&lt;p class="result"/&gt;')); // Bind event handler $ajaxForm.bind('submit', function(event, data) { // Simple ajax POST request // See http://api.jquery.com/jQuery.post/ $.post($ajaxForm.attr('action'), 'ajax=1&amp;' + $ajaxForm.serialize(), function(data) { $('.result').html(data); }); // Disable default form submit behavior return false; }); // Bind click handler to override "reset" behavior... // Although this really isn't necessary if you're using the HTML &lt;form&gt; element, which you should be... $ajaxForm.find('button:reset').bind('click', function(event, data) { var $els = $ajaxForm.find('input, textarea, select'); $els.filter('input:text, input:password, textarea').val(''); $els.filter('input:radio, input:checkbox').attr('checked', false); $els.filter('select').attr('selectedIndex', ''); return false; }); }); &lt;/script&gt; &lt;style type="text/css"&gt; fieldset { border: 0; padding: 0; margin: 0; } fieldset legend { display: none; } &lt;/style&gt; </code></pre>
