thanks in advance!

i assume use jquery if use bootstrap.

so following:

html:

<form class="navbar-form" role="search" method="get" action="<?=$domain?>search" id="searchfrom">     <div class="input-group">         <input type="text" id="searchfield" class="form-control input" placeholder="search" name="q">         <div class="input-group-btn">             <button  type="submit" class="btn btn-primary"><i class="glyphicon glyphicon-search"></i></button>         </div>     </div> </form> 

js:

$('body').on('submit','#searchfrom', function(e) {     e.preventdefault();     location.href = $(this).attr('action')+'/'+encodeuricomponent($('#searchfield').val()); });
