ESASky Javascript API - ESDC
ESASky Javascript API
All commands should be sent to the ESASky element as postMessages. For example by:
document.getElementById(esaskyFrameName).contentWindow.postMessage(command, ‘https://sky.esa.int’)
Where esaskyFrameName is the elementId where the esasky page is embedded, command is a JSON containing ‘event’ for function name and ‘content’ with all parameters
There are a number of commands that will send back response from ESASky. These will also be sent as http messages directed to the sender element of the command sent to ESASky. Unless otherwise specified this will probably be the main window for you. Add a message listener if you want to handle the data sent back as:
window.addEventListener("message",function(e){
var data = e.data;
// Code to handle the data
});
Available events described here and can be tested in the iframe on this page. Every command has a submit button which will send it to the iframe and paste it to the custom function input below the iframe. Here all responses from ESASky are also displayed:
