Let's fix this code first:

 <ul class="dropdown-menu" id="newloc">
 <?php
     $res_add = DB::table('res_br')->where('email',$user_email->email)->get();
     if(count($res_add) != "")
     {
        foreach($res_add as $rr1)
        {   
            echo '<li value="'.$rr1->street.'">'.$rr1->street.'</li>';
        }
     }
?>
</ul>

<button type="button" class="btn btn-block btn-primary" data-dismiss="modal" onClick="buildorder()" >Build Your Order</button>

Now your code outputs li-elements based upon the foreach.

Next the button code:

function buildorder()
{

      var radio =   $("input[name='newradio']:checked").val(); //this refers to an input that is not in this post, but I assume this refers to a location in the list.
      var location = $('#newloc').find('li'); //no this, let's use the id

      console.log(location.text()); //this will list all the li elements and there textContent

      alert(radio);
      alert(location);

}

This only fixes the code and will give you information from the lis. However since we don't know more about your code I can't help you further with selecting the correct li.

You can even assign the click handler to the button with jQuery.

$('button.btn.btn-primary').click(buildorder);
