<h2>Code snippets</h2>
<p>There are <strong>elements</strong> such as &lt;input/&gt; and <strong>containers</strong> like   &lt;form&gt; &lt;/form&gt;  Each element can have <strong>attributes</strong> associated   with it, such as: eg &lt;input/&gt; element has three attributes: <em>type</em>, <em>name</em> and <em>id</em></p>
<pre><strong>var inputs = document.getElementsByTagName("input");</strong><br>var message =<br>"Form has following <strong>input elements with 'type' attribute = 'text'</strong>: \n\n";<br>for (var i=0; i &lt; inputs.length; i++)<br>{<br><br>   if (inputs[i].getAttribute('type') == 'text')<br>   {<br>      message += inputs[i].tagName +<br>      " element with the 'name' attribute = '";<br>      message += inputs[i].getAttribute('name') + "'\n";<br>   }<br>}<br>alert(message);</pre>
<p><br>
  <strong>Toggle  visibility of the form</strong> by accessing  form   element &lt;form&gt;  and setting its <em>display</em> property:</p>
<pre class="brush: jscript; title: ; toolbar: false; notranslate" title="">var frm_element = document.getElementById('subscribe_frm');<br><br>var vis = frm_element.style;<br><br>if (vis.display=='' || vis.display=='none')<br>{<br>    vis.display = 'block';<br>}<br>else<br>{<br>    vis.display = 'none';<br>}
</pre>
<p><br>
  var name_element = document.getElementById (&lsquo;txt_name&rsquo;);</p>
<div>
  <pre class="brush: jscript; title: ; notranslate" title="">if (trim(name_element.value) == '')
  {     alert ('Please enter your name');  } 

function trim (str)  {
       return str.replace (/^\s+|\s+$/g, '');  } </pre>
</div>
<p>&nbsp;</p>
<p>To get a reference to the &lt;select&gt; element with the name attribute <em>mail_format</em>.</p>
<div>
  <pre class="brush: xml; title: ; toolbar: false; notranslate" title="">&lt;select name="mail_format" id="slt_mail_format"&gt;
  &lt;option value="TEXT"&gt;Plain Text&lt;/option&gt;
  &lt;option value="HTML"&gt;HTML&lt;/option&gt;  &lt;/select&gt;  </pre>
</div>
<p>We could access  desired element in this way:</p>
<div>
  <pre class="brush: jscript; title: ; toolbar: false; notranslate" title="">var mail_format_elements = document.getElementsByName('mail_format');  </pre>
</div>
<p>&nbsp;</p>
<p>&nbsp;</p>
<p>Here is a DIFFERENT IDEA for Tab - Enter: </p>
<ol>
  <li> change <strong>on submit so that it calls fn</strong> instead of processing form </li>
  <li> in function <strong>check all the fields to see if they are blank</strong></li>
  <li> <strong>focus on  next blank field</strong> (that doesn't have a value)</li>
  <li> 1 to 3 when script runs (in runtime) behaves so :<br>
    user types a value into field1 -&gt;
    hit enter -&gt; function runs<br>
    -&gt; Fn sees that field1 is full, 2 isnt, so focus on field 2 <br>
    -&gt; when all fields are full, submit form for processing </li>
</ol>
<p>If form has fields that can be blank, you could use a boolean array 
  that would keep track of which fields received focus using onfocus() event. </p>
