[英]Google map marker from JSON data - “Failed to load resource”
我正在嘗試從Police.uk API( http://data.police.uk/docs/method/crime-street/ )加載JSON數據,並在Google地圖上繪制標記。 但是,控制台說它無法加載資源。 誰能發現我的錯誤所在? 隨函附上我的代碼供您審核。 謝謝。

//Initializing the map
function initialize() {
var coords = [51.5600, 1.7800]
geocoder = new google.maps.Geocoder();
latlng = new google.maps.LatLng(51.5600, 1.7800);
var mapOptions = {

map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
var marker = new google.maps.Marker({

map:map,

})
getJSONpoliceuk(function(data){
var crimes = data.crimess;
var crime, latLng
for(i in crimes) {
crime = crimes[i];
latLng = new google.maps.LatLng(crime.latitude, crime.longitude);
var marker = new google.maps.Marker({

<body onload="initialize()">

使用此JSON調用
//Getting the data from the API (http://data.police.uk/docs/method/crime-street/)
function getJSONpoliceuk(callback){
$.getJSON('http://data.police.uk/api/crimes-street/all-crime?poly=52.268,0.543:52.794,0.238:52.130,0.478&date=2013-01', callback)
}
和以下回調函數
getJSONpoliceuk(function(data) {
var crime, latLng;
for(i in data) {
crime = data[i];
latLng = new google.maps.LatLng(parseFloat(crime.location.latitude),
parseFloat(crime.location.longitude));
var marker = new google.maps.Marker({
position: latLng,
map: map,
title: crime.category
});
}
});
我在地圖上有標記。
困擾我的是我得到的結果是在wamp服務器和純客戶端上運行html文件。
