How can I retrieve values of multiple input boxes that can be added dynamically,using JSP, Servlets?

        <!-- Text input-->
        <div class="form-group">
          <label class="col-md-4 control-label" for="textinput">Name:</label>
          <div class="col-md-8">

          </div>
        </div>

          <label class="col-md-4 control-label" for="textinput">Country:</label>
          <div class="col-md-4">
            <input id="textinput" name="textcntry" type="text" placeholder="" class="form-control input-md" >
          </div>
        </div>

          <!-- Text input-->
        <div class="form-group">
          <label class="col-md-4 control-label" for="textinput">Registration Number:</label>

          <!-- Text input-->
        <div class="form-group">
          <label class="col-md-4 control-label" for="textinput">Date of Dealing:</label>
          <div class="col-md-4">
            <input id="textinput" name="textDateDealing" type="date" class="form-control input-md" >
          </div>
        </div>

      </fieldset>

      <div id="contact-person-container">

      <div class="contact-person">
      <hr> 
      <fieldset id="modal_form">

      <button type='button' class='close closebtn'  aria-hidden='true'>&times;</button>
        <!-- Text input-->
        <div class="form-group">
          <label class="col-md-4 control-label" for="textinput">Contact Person:</label>
          <div class="col-md-4">
            <input id="textinput" name="textinput" type="text" placeholder="" class="form-control input-md" >
          </div>
        </div>

        <!-- Text input-->
        <div class="form-group">
          <label class="col-md-4 control-label" for="textinput">Phone #:</label>
          <div class="col-md-4">
            <input id="textinput" name="textinput" type="text" placeholder="(_ _ _) _ _ _ _ _ _ _" class="form-control input-md" >
          </div>
        </div>

        <!-- Text input-->
        <div class="form-group">
          <label class="col-md-4 control-label" for="textinput">fax #:</label>
          <div class="col-md-4">
            <input id="textinput" name="textinput" type="text" placeholder="(_ _ _) _ _ _ _ _ _ _" class="form-control input-md" >
          </div>
        </div>

        <!-- Text input-->
        <div class="form-group">
          <label class="col-md-4 control-label" for="textinput">Email:</label>
          <div class="col-md-8">
            <input id="textinput" name="textinput" type="email" placeholder="" class="form-control input-md" >
          </div>
        </div>



</fieldset>
</div> 

 </div>          
 <!-- /#contact-person-container -->             

  </div>
  <div class="modal-footer">
    <button type="button" id="addAnotherContactBtn" class="btn btn-   

primary">Add Another Contact</button>
        <button type="submit" class="btn btn-primary">Create Agent</button>
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
  </div>

    </form>

This is the part that we can have any number of input fields as necessary from the above form.

 <fieldset id="modal_form">

      <button type='button' class='close closebtn'  aria-hidden='true'>&times;</button>
        <!-- Text input-->
        <div class="form-group">
          <label class="col-md-4 control-label" for="textinput">Contact Person:</label>
          <div class="col-md-4">
            <input id="textinput" name="textinput" type="text" placeholder="" class="form-control input-md" >
          </div>
        </div>

        <!-- Text input-->
        <div class="form-group">
          <label class="col-md-4 control-label" for="textinput">Phone #:</label>
          <div class="col-md-4">
            <input id="textinput" name="textinput" type="text" placeholder="(_ _ _) _ _ _ _ _ _ _" class="form-control input-md" >
          </div>
        </div>

        <!-- Text input-->
        <div class="form-group">
          <label class="col-md-4 control-label" for="textinput">fax #:</label>
          <div class="col-md-4">
            <input id="textinput" name="textinput" type="text" placeholder="(_ _ _) _ _ _ _ _ _ _" class="form-control input-md" >
          </div>
        </div>

        <!-- Text input-->
        <div class="form-group">
          <label class="col-md-4 control-label" for="textinput">Email:</label>
          <div class="col-md-8">
            <input id="textinput" name="textinput" type="email" placeholder="" class="form-control input-md" >
          </div>
        </div>

How can I get the dynamic input boxes and then add it to a DB using servlets?

Answer 1

The ID's of your input elements have to be unique and to list all parameters you can use request.getParameterMap() and iterate through it from a servlet.

See Get all parameters from JSP page for more examples
