})

Will anyone check my program,If i am not giving any text to the input text box ,while submitting it should display the error message.

Answer 1

.validate() function of jquery validation is applied for form id not for table id.
You are given .validate() to table id

Answer 2

The validate plugin requires ID of the form to be validated unlike the id of the table you are using now tbl-employee . Wrap your HTML inside a form and the id of this form to validate.

$("#id_of_your_form").validate({..

Also, you are not having required attribute for the input textbox. Add it to the desired textboxes and the validations will work.

Eg. <input type="text" id="txt-name" required/>
