javascript - Uncaught ReferenceError: myFunction is not defined

Gives an error. I have placed the code just before </body>. Still getting the error.

<form action="" method="get" id="searchform" >
<input name="q" type="text" id="search" size="32" maxlength="128" class="txt">
<input type="button" id="hit" value="Search" onclick="myFunction();return false" class="btn">   
</form>

JS,

<script type="text/javascript">
    var nexturl = "";
    var lastid = "";
    var param;
    $(document).ready(function () {
        function myFunction() {
            param = $('#search').val();
            alert("I am an alert box!");
            if (param != "") {
                $("#status").show();
                var u = 'https://graph.facebook.com/search/?callback=&limit=100&q=' + param;
                getResults(u);
            }
        }
        $("#more").click(function () {
            $("#status").show();
            $("#more").hide();
            pageTracker._trackPageview('/?q=/more');
            var u = nexturl;
            getResults(u);
        });
    });
</script>

You cannot place myFunction after the onclick. When the onclick is seen there is no definition for myFunction.

Place the JavaScript in <head> tag. Also, move the function outside of ready().

Like this:

<script type="text/javascript">
var nexturl ="";
var lastid ="";
var param;

function myFunction() {
    param = $('#search').val();
    alert("I am an alert box!");
    if (param != "") {
        $("#status").show();
        var u = 'https://graph.facebook.com/search/?callback=&limit=100&q='+param;
        getResults(u);
        }
}

$(document).ready(function() {

  $("#more").click(function () { 

    $("#status").show();
    $("#more").hide();  
    pageTracker._trackPageview('/?q=/more');
    var u = nexturl;
    getResults(u);
  });

});
</script>
</head>
<body>
