【问题描述】:
我被困在这个问题上,我似乎无法为创建的对象变量分配新值。见下文:
// Vesselposition class
function vessel(name,ajaxName,dataUrl,pointLimit,polylineColor,iconUrl) {
this.name = name;
this.ajaxName = ajaxName;
this.dataUrl = dataUrl;
this.pointLimit = pointLimit;
this.polylineColor = polylineColor;
this.iconUrl = iconUrl;
// Global variables
this.lat=0;
this.lng=0;
this.latlng;
this.dateTime, this.vesselIcon, this.marker, this.polyline, this.localTemp, this.localWindSpeed, this.localWindDir;
this.countryName, this.countryCode, this.localTime, this.localSunrise, this.localSunset, this.countryFlag;
this.localTemp, this.localWindSpeed, this.localWindDir, this.myOptions, this.ib;
// Function gets position data
this.getData = function() {
$.when(
$.getJSON(this.dataUrl, { vessel: this.ajaxName, limit: this.pointLimit })
).done(function (data){
this.path = [];
// Create vessel icon for marker
this.vesselIcon = new google.maps.MarkerImage(this.iconUrl,
// This marker is 60 pixels wide by 58 pixels tall.
new google.maps.Size(60, 58),
// The origin for this image is 0,0.
new google.maps.Point(0,0),
// The anchor for this image is centered at 30,29 pixels.
new google.maps.Point(30, 29)
);
if (data.markers.length < 1) {
document.getElementById("map_canvas").innerHTML = "<h2>There was a problem obtaining vessel data, wait a couple of minutes and refresh your browser!</h2>";
} else {
for(i=0;i<data.markers.length;i++) {
// Assign lat,lng, id, dateTime and heading
this.lat = data.markers[i].marker.lat;
this.lng = data.markers[i].marker.lng;
我想要完成的是在for循环中分配this.lat和this.lng坐标值。稍后,这些值应该传递给 getData 方法。
请帮助大家!在网上搜索了 3 个小时!
