How to verify a google maps api key in html javascript?

由 江枫思渺然 提交于 2020-01-15 01:42:50
问题 I have a rather standard Google Maps page, using my own API key. The page only does some marker additions by JS and presenting it in a text-box. If the key is invalid or expired or whatever, the following page is displayed. That is fine, but then I would like to at lest tell the user why it is wrong. The map is accessed by standard: ... <script type="text/javascript" src="http://maps.google.com/maps/api/js?key=API_KEY"></script> </head> <body> <div id="map"></div> <p><input type="text"

问题 I am super green and need some help for a project. With my limited knowledge of html and javascript, I was able to make a google map with a number of locations. Here is my code (forgive me if it is bad, but it worked): <!DOCTYPE html> <html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8" /> <title>Google Maps Multiple Markers</title> <script src="http://maps.google.com/maps/api/js?sensor=false" type="text/javascript" src="https://maps.googleapis.com/maps/api/js

Google Maps Reverse Geocoding API returns nearest land address given a latlng in sea

由 半腔热情 提交于 2020-01-14 11:46:25
问题 In my project, I'm using Google Geocoding and Reverse Geocoding APIs to validate the addresses and latlngs provided by end users. Given latlng -37.857866,144.950706, the Reverse Geocoding API (https://maps.googleapis.com/maps/api/geocode/json?latlng=-37.857866,144.950706) returns the nearest land address. However on Google Map web page, that latlng actually is in the sea: https://www.google.com.au/maps/search/-37.857866,144.950706 Is there anyway that I can tell Google Reverse Geocoding API

Issues with KML Layers limit

由 半城伤御伤魂 提交于 2020-01-14 10:27:28
问题 I have loaded 6 kml layers via url to my website to be toggled off/on by checkboxes. I have recently notice though, that it will only allow me to show 4 kml's at a given time. When I select more than 4 the 5th and 6th does not show. It does not matter what ones I choose, it seems to limit me to only showing 4. Can someone direct me on what may be causing this or should I be coding this some other way? The kml's by themselves do work and are under 800kb. Is just seems very weird that I can

问题 There are two most popular react abstraction of google maps API( judging by the weekly npm downloads and github repo stars ). For a beginner like me, it is very confusing as I am not able to decide what can these libraries bring to my project and what not by merely looking at the documentation? In short what are the pros and cons of using google-map-react and react-google-maps. I didn't find any comparison on the internet or SO. 回答1: Be carefull, react-google-maps project is unmaintained more

How accurate are geocoding API's and what is the most accurate?

由 偶尔善良 提交于 2020-01-14 09:47:06
问题 I'm creating an application with google maps api with geocoding functionality. Obviously, I want to use the api that is the most accurate. I'm giving the application an address and I need to find it on a map, but I would be ok with just finding the latitude and longitude, and then I can use that to incorporate it into whatever map api I choose. Out of your experience, which api is the most accurate? Google, Yahoo, Bing, etc. And if you could give an approximate percentage that would be great.
