Form validation Using Jquery Plugin

Hello sir

I want to implement form validation using JQuery Plug-in. My code is :

<html>
<style type="text/css">
    * { font-family: Verdana; font-size: 11px; line-height: 14px; }
    .submit { margin-left: 125px; margin-top: 10px;}
    .label { display: block; float: left; width: 120px; text-align: right; margin-right: 5px; }
    .form-row { padding: 10px 0; clear: both; width: 800px; }
    label.error { width: 250px; display: block; float: left; padding-left: 10px; }
    input[type=text], textarea { width: 250px; float: left; }
    textarea { height: 50px; }
  </style>
</head>
<body>

<body>
<h3><font color="blue">Please enter the following information</font></h3>

  <form method="post" action="">
      <div class="form-row"><span class="label">Name *</span><input type="text" name="name" id="namei"/></div>
      <div class="form-row"><span class="label">E-Mail *</span><input type="text" name="email" id="emaili"/></div>

      <div class="form-row"><span class="label">URL</span><input type="text" name="url" id="urli" /></div>
      <div class="form-row"><span class="label">Age</span><input type="text" name="quantity" id="quantity" /></div>

      <div class="label.error" id="errmsg"></div>
      <div class="form-row"><span class="label">Your comment *</span><textarea name="comment" id="commenti"></textarea></div>
      <div class="form-row"><input class="submit" type="submit" value="Submit" name="submit" id="submiti"></div>
    </form>
</body>
</html>

Please provide me JQuery code regarding above code ASAP.

First you need to download jquery.validate.js plugin. Here is the code according to your description :

<script type="text/javascript" src="jquery.validate.js"></script> <script type="text/javascript">

$(document).ready(function(){
       //called when key is pressed in textbox  $("#quantity").keypress(function (e)    {   $("#errmsg").hide();      //if the letter is not digit then display error and don't type anything     if( e.which!=8 && e.which!=0 && (e.which<48 || e.which>57))     {         //display error message         $("#errmsg").html("&nbsp;&nbsp;Digits Only").show(); 
       return false;
      }       });     $('#quantity').blur(function(a) {       if((parseInt($("#quantity").val(), 10)<18))     {
      $("#errmsg").html("&nbsp;&nbsp;Age must be greater than 18").show(); 
          }       if((parseInt($("#quantity").val(), 10)>35))     {
      $("#errmsg").html("&nbsp;&nbsp;Age must be less than 35").show();       }      });
    //FOR EMAIL ADDRESS     $("#form").validate({
        rules: {
          name: "required",// simple rule, converted to {required:true}
          email: {// compound rule
          required: true,
          email: true
        },
        url: {
          url: true
        },
        comment: {
          required: true
        }
        },
        messages: {
          comment: "Please enter a comment."
        }
      });    });   </script>
