    You could use methods like in code below:

    <html>

    <head>

    <script>

    var arr = ["quote 1", "quote 2", "quote 3", "quote 4"];

    function pickquote() {

    var textinput = document.getElementById('textinput');

    textinput.value = arr[ Math.floor(( Math.random() * arr.length) + 0)];

    return textinput.value;

    }

    </script>

    </head>

    <body>

    <input type='text' id='textinput' size=80></input>

    <button type='button' onclick='pickquote();'>Please pick a quote</input>

    </body>

    </html>
