我有两个不同的JSON响应,从2个AJAX调用中获取。第一个将数据正确地绘制到Leaflet Map。但是,第二个不起作用。
<script type="text/javascript">
$(document).ready(function () {
var map = L.map('map').setView([22.6059596, 88.4277967], 13);
L.tileLayer('http://api.tiles.mapbox.com/v4/abhishekdepro.li9a02j1/{z}/{x}/{y}.png?access_token=pk.eyJ1IjoiYWJoaXNoZWtkZXBybyIsImEiOiI3ZXg1UzlFIn0.d584w0ILalmPRzbJwgxdTw#4', {

maxZoom: 18
}).addTo(map);
if (localStorage.getItem("user_contact") === null) {
} else {
document.getElementById("user").innerHTML = "Hello, " + localStorage.getItem("user_contact");
document.getElementById("_login").innerHTML = "Logout";
}
//var marker = L.marker([51.5, -0.09]).addTo(map);
//marker.bindPopup("<b>Hello world!</b><br>I am a popup.").openPopup();
$.ajax({
type: 'GET',
dataType: 'json',
url: 'https://bloodplus.herokuapp.com/geopoints',
success: function (data) {
var obj = data;
var totalLocations = obj.length;
var array = [];
var greenIcon = L.icon({
iconUrl: '/images/icon.png',
});
array = obj.bloods;
//alert(array.length);
for (var i = 0; i < array.length; i++) {
marker = new L.marker([parseFloat(array[i].tweet.lat), parseFloat(array[i].tweet.lon)], {
icon: greenIcon
})
.bindPopup(array[i].tweet.group + ', Contact: ' + array[i].tweet.contact).addTo(map);
}
another();
}
});
});
function another() {
$.ajax({
type: 'GET',
dataType: 'json',
url: 'https://bloodplus.herokuapp.com/geopoints',
success: function (data) {
var obj = data;
var totalLocations = obj.length;
//document.getElementById('name').value = parseFloat(obj.bloods[0].tweet.lat);
var array = [];
var greenIcon = L.icon({
iconUrl: '/images/icon.png',
});
array = obj.bloods;
//alert(array.length);
for (var i = 0; i < array.length; i++) {
marker = new L.marker([parseFloat(array[i].tweet.lat), parseFloat(array[i].tweet.lon)], {
icon: greenIcon
})
.bindPopup(array[i].tweet.group + ', Contact: ' + array[i].tweet.contact).addTo(map);
}
}
});
}
</script>
但是当我在此之后发出另一个AJAX请求时。标记没有加载,我得到一个错误:
TypeError:undefined不是函数(评估't.addLayer(this)')
答案 0 :(得分:2)
您需要使用new L.Marker
或L.marker
,而不是两者的组合 - new L.marker
。请参阅http://leafletjs.com/reference.html#class中的“类别工厂”部分。
