Validating generated input fields

Question

How will I validate the input boxes which are generated in a PHP for loop using jQuery? In my code I am using jquery.min.js library and jquery.validate.min.js and simply calling the validate function.

I am getting error messages for only first row but not for the other rows. any suggesion much appreciated ... thanxx in advance.

<html>
<head>
<TITLE></TITLE>
<script type="text/javascript" src="first/js/jquery.min.js"></script>
<script type="text/javascript" src="first/js/jquery.validate.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){

         $("#frm").validate({
                    rules:{
                        'name[]':{
                            required:true
                        },
                        'mail[]':{
                            required:true,
                            email:true
                         }
                    },
                    messages:{
            'name[]':{
                required:"Enter name"
            },
             'mail[]':{
                            required:" Enter mail",
                            email:"Enter valid mail"
                        }
                    },

                    submitHandler:function(){
                        form.submit();
                    }
                });
            });
</script>

You should title your question in a more on-topic way. The current title won't let people find your question or get an idea of its topic. — Denys Séguret, May 24 '13 at 12:34
thanxx for your suggesion ... can you please help me out ... — Sekhu, May 24 '13 at 12:40
I am not sure it is possible... the problem is that you have the same name for your elements...the plugin seems to not like this — mlwacosmos, May 24 '13 at 14:28

Most of the modern browsers now are HTML5 compatible and if you think your website will be accessed from HTML5 compatible browsers, I suggest that you use the required attribute for <input> and email type.

Eg:

<input type='text' name='name[]' required />
<input type='email' name='email[]' required />

These will only work if you write <!DOCTYPE HTML> before <html>.

I guess this would be the cleanest way to validate your input fields

IMO, this shouldn't be suggested as using `required` attribute for form validation isn't a good approach at this time, in 2 years' time maybe yes – asprin May 24 '13 at 13:53
Ya, i agree. That's why i have added a disclaimer in the first line.. For some applications where we know that the browsers will be update-to-date, i think it is a smart choice – draxxxeus May 24 '13 at 13:54
thanx friends .. got the esier answers from the above links . just few changes in the code in jquery.validate.js and it works ... – Sekhu May 25 '13 at 06:03

Indeed, it looks like it is not naturally possible.

But you can change the source of jquery.validate.js. There is another stackoverflow post :
