IV. Maps Javascript API

1. Registration

1.1. Introduction

Maps Javascript API helps integrating maps into your website. You only need to register to get a key to use the API. Once gets key, you can develop your applications according to our guide.

1.2. Target users

This document is written for those who know Javascript and Object-Oriented Programming at the basic level or higher. You can make your website similar to http://vietbando.com page if you take advantage of all the features of Maps JavaScript API.

1.3. Registration and using

To use Maps Javascript API you must first register service and create an authentication key.

After receiving the key, use the API key in the following way (eg API Key is: ABCDEFG):

<script type="text/javascript" src="https://developers.vietbando.com/V2/Scripts/VietbandoMapsAPI.js?key=ABCDEFG">

By this time you can use the classes, functions in the Maps JavaScript API. You can refer to the API Reference Document to better understand these class library and functions.

V. Static Maps API

1. Introduction

Static Maps API allows embedding map images to your website without the use of Javascript. Map images are created based on URL parameters sent through HTTP request and finally displayed on the website.

A simple example of using Static Maps API:

<img src="http://developers.vietbando.com/V2/StaticMapService.ashx?key=ABCDEFG&center=10.813747,106.649436&zoom=13&size=795x300&markers=color:red|label:A|10.815232,106.680505&markers=color:green|label:B|10.813747,106.649436|10.808689,106.635360&path=weight:5|color:red|fillcolor:0x9002E54F|10.815232,106.680505|10.813747,106.649436|10.808689,106.635360" />

You do not need to do anything "special" (even Javascript) to get map images displayed on your website. We just need to create an URL and put in <img/> tag. You can place Static Maps images anywhere (which can put an image) on the site.

This documentation is written for web and mobile developers who want to put Static Maps images on their websites or mobile applications, including introduction and detailed user manual for parameters.

2. Registration
