How to use Glyphicon instead of datepicker text box

问题

PFB the link of plunker .

http://jsfiddle.net/jomanlk/7NgpQ/

Here I want to use -

<span class="glyphicon glyphicon-calendar" id="full"></span>

instead of

<input type='text' id='full' name='fulldate'>

But if i use glyphicon, calendar is displaying on load only , i want to use it on selecting glyphicon icon only.Any pointers how to proceed on this.
