Answer 1

You can use jquery to get textarea value without form. And to save it to database use AJAX.
HTML
<textarea name="quoteinput" class="form-control mytextarea" rows="3" placeholder="Apa yang Anda pikirkan ?">{!! Input::old('quoteinput') !!}</textarea>
<button type="submit" class="btn btn-info pull-right">Posting</button>
Jquery and ajax:
$(document).on('click','button',function(e)
{
e.preventDefault();
var text = $('textarea.mytextarea').val(); //this is the value of textarea
$.ajax({
type:"POST",
url: "{{url('/timeline/quote')}}",
data: {
"_token": "{{ csrf_token() }}",
"text": text
},
success: function (data) {
var res = $.parseJSON(data);
if(res == true)
{
alert('saved');
}
}
});
});
Controller
public function postQuote(Request $request)
{
if($request->ajax())
{
$text=$request->text;
//save this textarea value to database
echo json_encode(TRUE);die;
}

You can't get value without creating form in html, wether you do it with form::open or by <form> tag. You also have to give the name to the textarea.
<div class="tab-pane active" id="tab_1">
<dorm method="GET" action="{!! URL::to('/timeline/quote') !!}">
<div class="box-body">
<textarea name="quoteinput" class="form-control" rows="3" placeholder="Apa yang Anda pikirkan ?">{!! Input::old('quoteinput') !!}</textarea>
</div>
<div class="box-footer">
<button type="submit" class="btn btn-info pull-right">Posting</button>
</div>
</form>
</div>
