I an using javascript and am getting an message that I have exceeded my daily request quota for this API. Is there a way to capture this error message in a try catch block so when I go over my quota I can execute another piece of code. I have seen several similar posts, but nothing that has been helpful. Here is my code.
(function (window, google, lat, lng) {
var options = {
center: {
lat: Number(lat),
lng: Number(lng)
},
zoom: 5,
disableDefaultUI: true,
scrollwheel: true,
draggable: false
},
element = document.getElementById('map-canvas')
var map = new google.maps.Map(element, options)
}(window, window.google, result[i]['latitude'], result[i]['longitude']));

Go to the Credentials section, which can be accessed from the left side bar under Google Maps Platform > Credentials. Check that the API key you currently use on your website is listed. If that's not the case, switch to a different project, and check the credentials there.
There are a several reasons why your google maps may not be working, the most common issue being no Google Map API key set or set incorrectly. To use the Google Maps JavaScript API, you must register your app project on the Google Cloud Platform Console and get a Google API key which you can add to your app.
Go to Theme Options > Other Options > Miscellaneous and paste copied API key to Google Maps API Key field: Click Save All Changes and you should be able to view Google Maps on your site.
Update As per the documentation:
if you want to programmatically detect an authentication failure (for example to automatically send an beacon) you can prepare a callback function. If the following global function is defined it will be called when the authentication fails. function gm_authFailure() {//code}
Here is a list of errors that the gm_authFaliure function should be able to catch. It also mentions a OverQuotaMapError error.
As per the documentation:
if too many requests are made within a certain time period, the API returns an OVER_QUERY_LIMIT response code.
So you should check the response code. If the Google maps javascript library does not allow to access to the response code then I recommend making a HTTP request to the API to get the response code.
function initMap(window, google, lat, lng) {
var options = {
center: {
lat: Number(lat),
lng: Number(lng)
},
zoom: 5,
disableDefaultUI: true,
scrollwheel: true,
draggable: false
},
element = document.getElementById('map-canvas'),
map = new google.maps.Map(element, options);
};
function googleMapsCustomError(){
alert('Google Maps custom error triggered');
}
// if you want to respond to a specific error, you may hack the
// console to intercept messages.
// check if a message is a Google Map's error message and respond
// accordingly
(function takeOverConsole() { // taken from http://tobyho.com/2012/07/27/taking-over-console-log/
var console = window.console
if (!console) return
function intercept(method) {
var original = console[method]
console[method] = function() {
// check message
if(arguments[0] && arguments[0].indexOf('OverQuotaMapError') !== -1) {
googleMapsCustomError();
}
if (original.apply) {
// Do this for normal browsers
original.apply(console, arguments)
} else {
// Do this for IE
var message = Array.prototype.slice.apply(arguments).join(' ')
original(message)
}
}
}
var methods = ['error']; // only interested in the console.error method
for (var i = 0; i < methods.length; i++)
intercept(methods[i])
