Copy input text from user and add to URL Button

Copy input text from user and add to URL Button

Hello,

I would like to know if it is possible to get the text from the following INPUT field.

My code looks currently so:
  1. <!-- ID -->
                    <div data-role="fieldcontain">
                        <fieldset data-role="controlgroup" data-mini="true">
                           <!-- Textfield -->
                            <input name="ID" id="textinput2" placeholder="ID" type="text"  style="width:100%;-moz-box-sizing:border-box;-webkit;box-sizing:border-box;box-sizing: border-box;"/>
                             <!-- Button -->
                            <div data-role="content"> <a data-role="button" href="http://www.EXAMPLE.com/">Go!</a></div>
                        </fieldset>
                   </div> 








Let´s say the User types 4455 into the input field.
What I want it that this 4455 should be added to the href of my BUTTON element.

When the user press on the button then he should call http:www.EXAMPLE.com/4455

First of all thank u all for every coming advise :)
