我正在嘗試編寫一個快速腳本，以便從Facebook獲取數據，然後僅使用簡單的拉伸多邊形將其繪製在Google地圖實例上。我已經獲得了所有社交資源和ajax工作，但無論我每次調用.getcoordinates（）時發生的任何事情，都會收到NPObject錯誤。具體爲「NPObject上的錯誤調用方法」。在我的文檔的第一行中，我調用了.getcoordinates（）。我環顧了一下StackO，並且嘗試了其他任何人一直在關於NPObject錯誤的任何事情，都無濟於事。有任何想法嗎？將KML對象寫入Google Earth API的NPObject錯誤
頭JS：
function drawgraph(name, z, x, y) {
// Create the placemark.
var polygonPlacemark = ge.createPlacemark('');
// Create the polygon.
var polygon = ge.createPolygon('');
polygon.setAltitudeMode(ge.ALTITUDE_RELATIVE_TO_GROUND);
polygonPlacemark.setGeometry(polygon);
// Add points for the outer shape.
var outer = ge.createLinearRing('');
outer.setAltitudeMode(ge.ALTITUDE_RELATIVE_TO_GROUND);
outer.getCoordinates().pushLatLngAlt(x - 0.005, y - 0.005, z);
outer.getCoordinates().pushLatLngAlt(x + 0.005, y + 0.005, z);
outer.getCoordinates().pushLatLngAlt(x - 0.005, y + 0.005, z);
outer.getCoordinates().pushLatLngAlt(x + 0.005, y - 0.005, z);
polygon.setOuterBoundary(outer);
//Create a style and set width and color of line
polygonPlacemark.setStyleSelector(ge.createStyle(''));
var lineStyle = polygonPlacemark.getStyleSelector().getLineStyle();
lineStyle.setWidth(5);
lineStyle.getColor().set('9900ffff');
// Add the placemark to Earth.
ge.getFeatures().appendChild(polygonPlacemark);
}
var ge = null;
google.load("earth", "1", {"other_params":"sensor=true"});
function init() {
init3d();
}
function initCB(instance) {
ge = instance;
ge.getWindow().setVisibility(true);
ge.getNavigationControl().setVisibility(ge.VISIBILITY_SHOW);
}
function failureCB(errorCode) {
}
function init3d() {
google.earth.createInstance('map3d', initCB, failureCB);
}
我打電話的init（）對身體的onload
HTML前端：
<div id="map3d" style="height: 600px; width:100%; margin:0; "></div>
<div id="form" style="text-align:center; width:100%; margin-top:10px;">
<button id = "getcoord" style="background-color:#707070">Get coordinates of Current view</button>
<form id = "form" style="display:inline;" method="GET">
<input type="text" name="place" id="place" >
<select name="dist" id="dist">
<option value="1609">1 Mile</option>
<option value="3218">2 Miles</option>
<option value="8046">5 Miles</option>
<option value="16090">10 Miles</option>
</select>
<select name="number" id="number">
<option value="10">10</option>
<option value="50">50</option>
<option value="100">100</option>
<option value="1000">1000</option>
<option value="5000">5000</option>
</select>
<button id="submit" type="submit">Submit</button>
</form>
</div>
的onload JS：
$('#form').submit(function(event){
var fdata = {
'place' : $('#place').val(),
'dist' : $('#dist').val(),
'quantity' : $('#number').val(),
};
console.log(fdata);
$.ajax({
type: "POST",
url: "fb_back.php",
data: fdata,
cache:false,
}).done(function(data) {
for(var i = 0; i < data.length; i++) {
// get variables from json return
var name = +(data[i]["name"]);
var hgt = +(data[i]["checkins"]);
var lat = +(data[i]["lat"]);
var lng = +(data[i]["lng"]);
drawgraph(name, hgt, lat, lng);// create the polygon
} // for loop
}),//success
event.preventDefault();
});//form submit
PHP後臺越來越阿賈克斯電話：
//get ajax data
$distance = $_POST["dist"];
$place = $_POST["place"];
$limit = $_POST["quantity"];
// get the lat and long of the sent address to use for the fb request
$geo_return = file_get_contents("https://maps.googleapis.com/maps/api/geocode/json? address=".urlencode($place)."&key=AIzaSyDeEkWgri9GAvDVE4QN9j2IeO4_2Dj61iM");
$geo_returned = json_decode($geo_return);
foreach ($geo_returned->results as $results){
$lat = $results->geometry->location->lat;
$lng = $results->geometry->location->lng;
}
//make the fb request for a token and for the data then decode the data and stick it into the $decoded array
$center = $lat . "," . $lng;
$fb_key = file_get_contents("https://graph.facebook.com/oauth/access_token?client_id=[my id]&client_secret=[my secret]grant_type=client_credentials");
$ini = "https://graph.facebook.com/v2.1/search? limit=".$limit."&offset=0&type=place¢er=".$center."&distance=".$distance."";
$fb_get = $ini . "&" . $fb_key;
$fb_got = file_get_contents($fb_get);
$decoded = json_decode($fb_got, true);
$decoded = $decoded['data'];
//setup the foreach loop, the $data variable is where each entry will be stored
$data = array();
$i = 0;
foreach ($decoded as $value) {
//pull the name and the fb id of the place from the object in this iteration of the loop
$name = $value['name'];
$each_id = $value['id'];
//pull the fb json file for this place using the id
$pull = "https://graph.facebook.com/v2.1/". $each_id . "?" . $fb_key;
$detail_array = file_get_contents($pull);
$decode_detail = json_decode($detail_array);
//pull out the checkins as well as the latitude and longitude of the place
$checkins = $decode_detail->checkins;
$fblat = $decode_detail->location->latitude;
$fblng = $decode_detail->location->longitude;
//make another associative array with the variables for the kml objects in fb_front
$entry = array(
"name" => $name,
"checkins" => $checkins,
"lat" => $fblat,
"lng" => $fblng,
);
//store the entry array and step the index variable
$data[$i]=$entry;
$i++;
}
//dump it back out to fb_front
var_dump(json_encode($data));
我真的很抱歉給你們轉儲文字牆我只是出於想法。
