title: Textarea validation with jQuery
body: <p>I wish to have input of only letters into a text area in form
  It works well with the input fields, can't validate the textarea is it possible with jquery validate ? or what is another alternative 
  2) will this block malicious code input (such as xss.js) </p>
  
  <pre><code>      &lt;form action="" method="POST" enctype="multipart/form-data" name="messageForm"&gt;
    &lt;p&gt;name of sender: 
     &lt;input class="input" name="sender" id="sender" value="" size="13"
       maxlength="13" dir="ltr" autocomplete="on" type="text" height="20" minlength="3" required&gt;&lt;br&gt;
     &lt;p&gt;name of receiver: 
        &lt;input class="input" name="receiver" id="receiver" value="" size="13"
       maxlength="13" dir="ltr" autocomplete="on" type="text" height="20" minlength="3" required&gt;&lt;br&gt;
     &lt;p&gt;Message: &lt;br&gt;
       &lt;textarea name="message" id="message"  type="text" value="" rows="5" cols="30" dir="ltr" required&gt;&lt;/textarea&gt;&lt;br&gt;
     &lt;input value="Submit" name="button" alt="submit" onsubmit="" border="0" type="submit" align="absmiddle"&gt;&lt;/p&gt;
  
   &lt;/form&gt;
  &lt;script&gt;
      $("#messageForm").validate();
  &lt;/script&gt;
  </code></pre>
  
  <p>javascript</p>
  
  <pre><code>$().ready(function () {
  
      $("#submit").validate({
      rules: {
          sender: {
              required: true,
              minlength: 3,
            lettersonly: true
          },
          receiver: {
              required: true,
              minlength: 3,
              lettersonly: true
          },
          message: {
            required: true,
            minlength: 5,
            maxlength: 30,
            lettersonly: true
          },
        },
       messages: {
                  sender: {required:"Please enter your name"},
                  receiver:{required: "Please enter receiver name up to 3 characters"},
                  message: {required: "Enter your message 3-20 characters"},
            },
   });
  </code></pre>
  
  <p>});</p>
