试图显示多个标记，但不起作用。
我试图在谷歌地图上显示多个标记，但我遇到了多个错误InvalidValueError:setTitle:不是字符串。
InvalidValueError:setCenter:不是具有有限坐标的LatLng或LatLngLiteral:在属性lat:NaN中不是可接受的值
<script>
let cord = []
$(`.cord`).each(( i , el) => {
cord[i] = {
'latitude': Number($(el).data('latitude')),
'longitude': Number($(el).data('longitude')),
}
});
// Initialize and add the map
function initMap() {
let uluru;
uluru = { lat: -33, lng: 151 };
// The map, centered at Uluru
const map = new google.maps.Map(document.getElementById("map"), {
zoom: 4,
center: uluru,
});
var i = 0;
while(Object.values(cord).length>i){
// The marker, positioned at Uluru
const map = new google.maps.Map(document.getElementById("map"), {
zoom: 4,
center: uluru,
});
uluru = { lat: cord[i]['latitude'], lng: cord[i]['longitude'] };
const marker = new google.maps.Marker({
position: uluru,
map: map,
title: i,
});
i++;
} //loop
} //map
</script>
i不是字符串，它是一个数字。要修复错误InvalidValueError: setTitle: not a string，请将其更改为一个：
const marker = new google.maps.Marker({
position: uluru,
map: map,
title: "" + i, // Change `i` to a string
});
let cord = []
$(`.cord`).each((i, el) => {
cord[i] = {
'latitude': Number($(el).data('latitude')),
'longitude': Number($(el).data('longitude')),
}
});
// Initialize and add the map
function initMap() {
console.log(cord);
let uluru;
uluru = {
lat: -33,
lng: 151
};
// The map, centered at Uluru
const map = new google.maps.Map(document.getElementById("map"), {
zoom: 4,
center: uluru,
});
var i = 0;
while (Object.values(cord).length > i) {
uluru = {
lat: cord[i]['latitude'],
lng: cord[i]['longitude']
};
const marker = new google.maps.Marker({
position: uluru,
map: map,
title: ""+i,
});
i++;
} //loop
} //maphtml, body, #map {
