Also, this is part of the code:
We only wait for the callback and then get the credentials to log in and
define our style. but the callback is never invoked in the failed case
public static loadApi(callback: () => void = null): void {
if (MapUtil.loaded) {
callback();
} else {
var script =
<HTMLScriptElement>document.createElement("script");
script.src =
"https://www.google.com/jsapi?callback=MapUtil.googleLoaderCallback";;
script.type = "text/javascript";
document.getElementsByTagName("head")[0].appendChild(script);
MapUtil.loadApiCallback = callback;
}
}
public static googleLoaderCallback() {
MapUtil.loaded = true;
let credentials =
window.sessionStorage.getItem("googleMapsApiCredentials");
if (credentials === null || credentials === "") {
KnockoutUtil.ajax({
url: "/api/configurationapi/GetGoogleMapsAPICredentials",
type: "GET",
contentType: "application/json; charset=utf-8",
dataType: "json",
async: false,
success: (data: string) => {
if (data !== null && data !== "") {
credentials = data;
window.sessionStorage.setItem("googleMapsApiCredentials", credentials);
}
},
error: () => {
throw new Error("Credentials could not be loaded")
}
})
}
let a: object;
(<any>google).load("maps", "3", {
"other_params":
`client=${credentials}&sensor=false&channel=${client}&libraries=geometry,visualization,places,drawing
`,
"callback": () => {
MapUtil.impactMap = new
google.maps.StyledMapType(MapUtil.MAP_IMPACT, { name: "Impact" });
MapUtil.loadApiCallback();
MapUtil.createPopupClass();
}
});
}
