如何验证jquery .Validation（）中的动态datepicker？

Question

I am trying to insert dynamic datepicker in the database. Everything works fine! except jquery .validation. Done a validation rule if the input fields are empty a required message should be displayed has "please select a date" for ex: if I add three dynamic rows, while kept it in empty and pressed submit button, it shows validation message as "Please select a date" Now move to the three rows!

a) In first row I have picked a date, then I pressed submit button, It shows "Please select a date" in remaining input fields

b) Then next I have selected a date in a second input field and press the submit button, In here what needs to happen is third input field shows the validation message, but the datepicker automatically show in the second input field. I don't know why is automatically showing datepicker in the second input field while its already date has picked...

<div class="form-body pal">
    <div class="col-md-12 col-md-offset-10">
        <div class="form-group">
            <button type="button" id="add_details_button" class="btn btn-info add_details_button"><i class="fa fa-plus"></i> Add Date</button>    //class name used for onclick to add row
        </div>
    </div>

If you create inputs with same name won't work

<input type="text" name="date[]" />
<input type="text" name="date[]" />
<input type="text" name="date[]" />
<input type="text" name="date[]" />

Instead of this

 <input type="text" name="date[0]" />
    <input type="text" name="date[1]" />
    <input type="text" name="date[2]" />
    <input type="text" name="date[3]" />

Just add indexes for each inputs

and in validator write rules for dateField[] or include required attribute in input tag.

I hope this will help you.
