Adding multiple strings into an input field via multiple buttons

Question

I'm trying to add multiple strings to an input field via multiple buttons. The problem is, is that every time I click a new button it replaces/overrides the previous insert so I cant add strings only replace.

Would also like to remove the string if the same button is re-clicked

Please see code below and fiddle - http://jsfiddle.net/2khzX/

 <input type="text" id="text" style="width: 450px;" />
 <br />
 <button>Hello</button>
 <button>Yes</button>
 <button>No</button>
 <button>Maybe</button>

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js">    </script>
 <script>
  $("button").on('click', function() {
    var text = $(this).text();
    $("input").val(text + ',');
  });
 </script>

First, get the value from the existing input.

Then check to see if the current text already exists. If so, get rid of it.

Then append the current text onto the end.

$("button").on('click', function() {
    var text = $(this).text() +',';
    $('input').val(function(_, val) {
        if (val.match(text)) {
            return val.replace(text, '');
        }
        return val + text;
    });
});

Add the value that is already in the input as well, otherwise it just replaces whatever is there with the new value

$("button").on('click', function() {
    var text = $(this).text();

    $("input").val(function(_, val) {
        var arr = val.split(','),
            pos = $.inArray(text, arr);

        pos != -1 ? arr.splice(pos, 1) : arr.push(text);

        return arr.filter(function(n) {
            return n.trim().length
        }).join(',');
    });
});

FIDDLE

Thanks, works great, but how do you remove the value if clicked again?
