title: Getting a specific input from a specific form?
body: <p>I'm having difficulty grabbing a specific input from a specific form.  Any tips?</p>
  
  <pre><code>&lt;form id ="frm_addtag-1"&gt;
      &lt;input type="text" name="tag" id="tag"&gt;
  &lt;/form&gt;
  
  &lt;form id ="frm_addtag-2"&gt;
      &lt;input type="text" name="tag" id="tag"&gt;
  &lt;/form&gt;
  
  &lt;form id ="frm_addtag-3"&gt;
      &lt;input type="text" name="tag" id="tag"&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>If frm_addtag-1 is submitted, I only want to grab the tag input from that form and not the other forms.  </p>
  
  <p>When I do something like the below, it will return the tag inputs from any other the forms regardless of which form is submitted.</p>
  
  <pre><code>var tag = $("#tag");
  var tag = tag.attr("value");
  </code></pre>
