title: how to POST radio button values through jquery
body: <p>i have this example code:</p>
  
  <pre><code> while ($row = mysql_fetch_object($result1)) {                  
                      echo '&lt;input type="radio" name="vote" value='.$row-&gt;avalue.'/&gt;&amp;nbsp;';
                      echo '&lt;label &gt;'.$row-&gt;atitle.'&lt;/label&gt;&lt;br&gt;';
                  }
  </code></pre>
  
  <p>this displays 4 radio buttons alongwith their labels.
  now I am using the following jquery function to POST.</p>
  
  <pre><code>$("#submit_js").click(function() {
      $.post(
      "user_submit.php", 
      {//how to POST data?}, 
      function(data){
      });
  });
  </code></pre>
  
  <p>I want to post the value associated with the radio button. but how do i select the value?
  how do i determine what radio button is selected and POST it?</p>
