チェックボックスの選択に応じて Google マップ キャンバスを表示したいのですが、クリックしてもマップがうまく表示されず、マップが正しく表示されず、「マップ機能」も機能しません..... css リンクは map_canvas の div サイズを設定します。この show 関数を削除すると、マップは完璧に機能します。コードは次のとおりです。

  <html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">

<link href="https://developers.google.com/maps/documentation/javascript/examples/default.css" rel="stylesheet">

<script type="text/javascript" src="../jquery-1.2.1.pack.js"></script>


<script type="text/javascript">

function lookup(inputString) {

    if(inputString.length == 0) {



        // Hide the suggestion box.

        $('#suggestions').hide();

    } else {


        $.post("do_search.php", {queryString: ""+inputString+""}, 
function(data){


            if(data.length >0) {
                        alert(data);
                $('#suggestions').show();
                $('#autoSuggestionsList').html(data);
            }
        });
}


} // lookup





//alert(queryString);


</script>



<script>
  function initialize() {
    var mapOptions = {
       center: new google.maps.LatLng(-35.48833, -62.97528),

      mapTypeId: google.maps.MapTypeId.ROADMAP
    };

    var map = new google.maps.Map(document.getElementById('map_canvas'),
      mapOptions);

    var drawingManager = new google.maps.drawing.DrawingManager({

      drawingControl: true,
      drawingControlOptions: {

        var coordinates = "";

        var path = polygon.getPath();

        for (var i = 0; i < path.getLength(); i++)
            coordinates += path.getAt(i) + ",";

        //alert(coordinates);
        lookup(coordinates);

        drawingManager.drawingControlOptions.drawingModes = [];

<body>
<input type="checkbox" name="fldcheckbox" id="fldcheckbox"   onclick="fnchecked(this.checked);"/>mapa
<div id="map_canvas" style="display:none;">

何か案が？

このようにコードを変更します
