My Google Map has suddenly stopped working despite me not making any changes to the code and I cannot work out why.

The map.js I am using is:

 var geocoder;
    var map; 
    var marker;
    var layers = [];

  function initialize() {
    geocoder = new google.maps.Geocoder ();
    var latlng = new google.maps.LatLng (50.31697, -3.670807);
    var myOptions = {
      zoom: 10,
      center: latlng,
      mapTypeId: google.maps.MapTypeId.ROADMAP
        }
      map = new google.maps.Map(document.getElementById("map-container"),
        myOptions);
      marker = new google.maps.Marker({map:map});

      layers[100] = new google.maps.KmlLayer('http://www.southdevonaonb.org.uk/cordialemapping/kmzdata/100.kml', {preserveViewport: true});
      layers[200] = new google.maps.KmlLayer('http://www.southdevonaonb.org.uk/cordialemapping/kmzdata/200.kml', {preserveViewport: true});
      layers[300] = new google.maps.KmlLayer('http://www.southdevonaonb.org.uk/cordialemapping/kmzdata/boundaryline.kml', {preserveViewport: true});




      layers[0] = new google.maps.KmlLayer('http://www.southdevonaonb.org.uk/cordialemapping/kmzdata/beta0.kml', {preserveViewport: true});
      layers[1] = new google.maps.KmlLayer('http://www.southdevonaonb.org.uk/cordialemapping/kmzdata/beta1.kml', {preserveViewport: true});
      layers[2] = new google.maps.KmlLayer('http://www.southdevonaonb.org.uk/cordialemapping/kmzdata/beta2.kml', {preserveViewport: true});
      layers[10] = new google.maps.KmlLayer('http://www.southdevonaonb.org.uk/cordialemapping/kmzdata/beta10.kml', {preserveViewport: true});
      layers[11] = new google.maps.KmlLayer('http://www.southdevonaonb.org.uk/cordialemapping/kmzdata/beta11.kml', {preserveViewport: true});
       layers[18] = new google.maps.KmlLayer('http://www.southdevonaonb.org.uk/cordialemapping/kmzdata/alpha18.kml', {preserveViewport: true});
       layers[19] = new google.maps.KmlLayer'http://www.southdevonaonb.org.uk/cordialemapping/kmzdata/withtiledoverlays/19/doc.kml', {preserveViewport: true});
      layers[20] = new google.maps.KmlLayer'http://www.southdevonaonb.org.uk/cordialemapping/kmzdata/withtiledoverlays/20/doc.kml', {preserveViewport: true});
      layers[21] = new google.maps.KmlLayer'http://www.southdevonaonb.org.uk/cordialemapping/kmzdata/withtiledoverlays/21/doc.kml', {preserveViewport: true});
     layers[22] = new google.maps.KmlLayer'http://www.southdevonaonb.org.uk/cordialemapping/kmzdata/withtiledoverlays/22/doc.kml', {preserveViewport: true});
    layers[23] = new google.maps.KmlLayer('http://www.southdevonaonb.org.uk/cordialemapping/kmzdata/withtiledoverlays/23/doc.kml', {preserveViewport: true});
      layers[24] = new google.maps.KmlLayer('http://www.southdevonaonb.org.uk/cordialemapping/kmzdata/withtiledoverlays/24/doc.kml', {preserveViewport: true});
      layers[25] = new google.maps.KmlLayer('http://www.southdevonaonb.org.uk/cordialemapping/kmzdata/withtiledoverlays/25/doc.kml', {preserveViewport: true});
      layers[26] = new google.maps.KmlLayer('http://www.southdevonaonb.org.uk/cordialemapping/kmzdata/withtiledoverlays/26/doc.kml', {preserveViewport: true});
      layers[46] = new google.maps.KmlLayer('http://www.southdevonaonb.org.uk/cordialemapping/kmzdata/holbeton.kml', {preserveViewport: true});
      for (var i = 1; i < layers.length; i++) {
      }
        }
    function codeAddress () {
        var address = document.getElementById ("address").value;
        geocoder.geocode ( { 'address': address}, function(results, status)  {
        if (status == google.maps.GeocoderStatus.OK)  {
            map.setCenter(results [1].geometry.location);
            marker.setPosition(results [1].geometry.location);
            map.setZoom(14);
            } 
        else {
            alert("Geocode was not successful for the following reason: " + status);
                }
    }); 
    }

    function toggleLayer(i) {
      if(layers[i].getMap() === null) {
        layers[i].setMap(map);
      }
      else {
        layers[i].setMap(null);
      }
    }
      google.maps.event.addDomListener(window, 'load', initialize);

The only thing I could think of was if the dimensions of the map container were not defined, but these have not been changed and were working fine before.

当我打开您的页面时，我的浏览器 (Chrome) 显示 javascript 错误：

未捕获的 SyntaxError：意外的字符串

在这条线上：

layers[19] = new google.maps.KmlLayer'http://www.southdevonaonb.org.uk/cordialemapping/kmzdata/withtiledoverlays/19/doc.kml', {preserveViewport: true});

它应该是：

layers[19] = new google.maps.KmlLayer('http://www.southdevonaonb.org.uk/cordialemapping/kmzdata/withtiledoverlays/19/doc.kml', {preserveViewport: true});

你似乎失去了一个“（”。很难看出如果没有人改变它怎么会发生。
