如何修复 Uncaught InvalidValueError: setPosition: not a LatLng or LatLngLiteral: in property lat: not a number?

问题描述

我正在尝试将我的 googlemaps v2 功能移植到 v3.

I'm trying to port my googlemaps v2 functions to v3.

但不知何故，我陷入了一个奇怪的错误，我找不到，我做错了什么.

But somehow i stuck in a strange error and i could not find, what i'm doing wrong.

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

这里是我的地图初始化:

Here my map initialisation:

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, function(i, trader) {
var icon = options.icon_image_uri;

var markerIcon = new google.maps.MarkerImage(icon,
    // This marker is 20 pixels wide by 32 pixels tall.
    new google.maps.Size(25, 25),
    // The origin for this image is 0,0.
    new google.maps.Point(0,0),
    // The anchor for this image is the base of the flagpole at 0,32.
    new google.maps.Point(0, 32)
);

var html = 'test';

/*Information from chromium debugger
trader: Object
    geo: Object
        lat: "49.014821"
        lon: "10.985072"

*/
var myLatlng = new google.maps.LatLng(trader.geo.lat,trader.geo.lon);

/*here is the error in new google.maps.Marker()*/
var marker = new google.maps.Marker({
    position:   myLatlng,
    map: map,
    icon : markerIcon,
});

var infowindow = new google.maps.InfoWindow({
    content: html
});
}

drawTraders 的调用

the call of drawTraders

 drawTraders(map, {
        traders_uri: "getTraders.php",
        icon_image_uri: "icon-cms.gif",
 });

我使用了这个例子信息窗口

推荐答案

意味着您没有将数字传递到 google.maps.LatLng 构造函数中.根据您的评论:

Means you are not passing numbers into the google.maps.LatLng constructor. Per your comment:

/*Information from chromium debugger
trader: Object
    geo: Object
        lat: "49.014821"
        lon: "10.985072"

*/

trader.geo.lat 和 trader.geo.lon 是字符串，而不是数字.使用 parseFloat 将它们转换为数字:

trader.geo.lat and trader.geo.lon are strings, not numbers. Use parseFloat to convert them to numbers:

var myLatlng = new google.maps.LatLng(parseFloat(trader.geo.lat),parseFloat(trader.geo.lon));
