Looking to utilize this Bootstrap code for generating an address and adding copy button functionality:
<div class="modal fade" id="bitcoinModal" role="dialog">
<div class="modal-dialog modal-lg">
<div class="modal-content">
<div class="container">
<div class="offset-top-20 text-md-left">
<button type="button" class="close" data-dismiss="modal">×</button>
<h3>Copy address</h3>
</div>
<div class="section-60 offset-top-35">
<div class="offset-top-20 text-md-center">
<form class="rd-mailform form-inline-custom text-left" data-form-output="form-output-global" data-form-type="subscribe" method="post" action="http://.........">
<div class="form-group form-group-outside">
<div class="input-group">
<label class="form-label form-label-outside text-dark" for="forms-subscribe-email">Bitcoin Address</label>
<input class="form-control" id="forms-subscribe-email" type="text" name="bitcoin_address" value="3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy " data-constraints="@Required"/>
</div>
<div class="input-group-btn">
<button class="btn btn-width-165 btn-primary" type="submit">Copy</button>
</div>
</div>
</form>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
Need a way to copy the input content and automatically close the form once it's copied into the clipboard. Any suggestions?
