How to use multiple Submit buttons in a single form having Ajax
<p>I'm building a simple website which uses mysql as backend. I have a form which has 2 buttons of which one searches data from db and populates the page using Ajax another button updates the new values to db. Now my problem is i can't use both buttons as 'Submit' button.</p>

<p>Ajax Method &amp; Html Form:</p>

<pre><code>&lt;script type="text/javascript"&gt;
     $(document).ready(function(){  
           $(document).on('submit', '#update-form', function(){
                var data = $(this).serialize();
                $.ajax({
                    type : 'POST',
                    url  : 'search.php',
                    data : data,
                    success :  function(data){
                        $(".display").html(data);
                    }
                });
                return false;
            });
        });
&lt;/script&gt;
&lt;body&gt;
  &lt;div id="update" class="tab-pane fade"&gt;
                &lt;form id="update-form" role="form" class="container" method="post" action="search.php"&gt;
                    &lt;h3&gt;Update details&lt;/h3&gt;
                    &lt;table class="display"&gt;
                        &lt;tr  class="space"&gt;
                            &lt;td&gt;&lt;label&gt;File Number:&lt;/label&gt;&lt;/td&gt;
                            &lt;td&gt;&lt;input type="text" class="form-control" name="filenum" required&gt;&lt;/td&gt;
                        &lt;/tr&gt;
                    &lt;/table&gt;
                    &lt;button type="submit" class="btn btn-default text-center" name="search_btn" &gt;Search&lt;/button&gt;      
                    &lt;button type="submit" class="btn btn-default text-center"  name="submit_btn" formaction="update.php"&gt;Update&lt;/button&gt;
                &lt;/form&gt;
            &lt;/div&gt;
&lt;/body&gt;
</code></pre>

<p>Now i want to know how can i modify above code so that i can use both button as submit.</p>

<p><b>Tried with</b><code>formaction</code> <b>but it doesn't work because of Ajax method usage.</b></p>
