我正在尝试将我的googlemaps v2功能移植到v3.

但不知怎的,我陷入了一个奇怪的错误,我无法找到,我做错了什么.

错误:未捕获的InvalidValueError:setPosition:不是LatLng或LatLngLiteral:在属性lat中:不是数字%7Bmain,adsense,geometry,zombie%7D.js:25

这里我的地图初始化:

var map = new google.maps.Map(document.getElementById("map"),{
  zoom:4
  size:new google.maps.Size(580,440),
  mapTypeControl: true,
  mapTypeControlOptions: {
    style:google.maps.MapTypeControlStyle.VERTICAL_BAR,
    position: google.maps.ControlPosition.BOTTOM_CENTER,
  },
  panControl: true,
  panControlOptions: {
    position: google.maps.ControlPosition.TOP_LEFT,
  },
  zoomControl: true,
  zoomControlOptions: {
    style: google.maps.ZoomControlStyle.LARGE,
    position: google.maps.ControlPosition.LEFT_CENTER,
  },
  scaleConrol: true,
  scaleControlOptions:{
    position: google.maps.ControlPosition.TOP_LEFT ,
  },
});
map.setCenter(new google.maps.LatLng(49.477643, 9.316406));

这里是我的错误的部分:

function drawTraders(map, options) {
var traders_uri = options.traders_uri || '';
if ('' == traders_uri) {
    return false;
}

// get the informations
$.getJSON(traders_uri, function(data) {
    // look through the information
$.each(data.traders, …
