$().ready(function(){
    $("#feed").validate();
}); 

Form:

<form name="feed" id="feed" action="feed.php">                                                              
    <table cellpadding="0" cellspacing="0" border="0" class="primaryTable" width="100%">
        <tr>
            <td><label>Name</label></td>
            <td><input type="text" class="inputField {required: true}" /></td>
        </tr>
        <tr>
            <td><label>Email</label></td>
            <td><input type="text" class="inputField {required: true}" /></td>

        <tr>
            <td><label>Title</label></td>
            <td><input type="text" class="inputField {required: true}" /></td>
        </tr>
    </table>
</form>

If there is any wrong in usage please notify me. Thanks in advance.

You need to specify the name attribute for your inputs to be picked up by the validator (I would recommend specifying id as well and using the for attribute on labels). Also, you should just use class="required" to designate a form field as required:

<form name="feed" id="feed" action="feed.php">                                 
    <table cellpadding="0" cellspacing="0" border="0" class="primaryTable" width="100%">
    <tr>
        <td><label>Name</label></td>
        <td><input name="name" type="text" class="required" /></td>
    </tr>
    <tr>
        <td><label>Email</label></td>
        <td><input name="email" type="text" class="required" /></td>
    </tr>
    <tr>
        <td><label>Title</label></td>
        <td><input type="text" name="title" class="required" /></td>
    </tr>
    </table>
</form>
