Scripts gathering external website data

[grctest]

Could grab:

• The latest block numbers from the explorers and full node websites.
• The latest prices from multiple exchanges
• Steemit content?

We need to change the cross site scripting security though & we shouldn't make the website too slow nor tacky/bulky.

Has to be JS, we don't have access to the underlying web server terminal.

As soon as I've completed the upgrade of Gridcoinstats I can supply the Gridcoin webpage with API access, trough JS, to the basic functions. This would include functions like latest block number and exchange prices (gathered by gridcoinstats).

Timeframe: 1-2 months

Two Public functions that can be used for the webpage for latest Projects status, Active (whitelisted) or Inactive and latest Block information on the chain.

Latest Projects Data: https://www.gridcoinstats.eu/API/api.php?a=getProjectData

Data: Array(
 "active"=>Array(name=>string, url=>string, lastActive=>date),
 "inactive"=>Array(name=>string, url=>string, lastActive=>date)
)

Latest Block Data: https://www.gridcoinstats.eu/API/api.php?a=getLastBlock
Data: Array(id=>string, hash=>string, blockTime=>date, blockDiff=>double, totalBlockMinted=>double)

Coinmarketcap has a public API for grabbing the latest price feed for Gridcoin.

Sample code to get this working with jQuery

    function loadBlocksData() {
      var request = $.ajax({
        url:'https://www.gridcoinstats.eu/API/api.php?a=getLastBlock',
        crossDomain: true,
        dataType: 'json',
      });
      request.done(function(data) {
        $('#blockDataDiv').append('Block ID: ' + data['id'] + ', Block Hash: ' + data['hash'] + ', Time: ' + data['blockTime']);
      });
    }

$(document).ready(function() {
     loadBlockHeaders();
});

This issue has arisen again regarding the slack invite portal being added to the gridcoin website.

I can change the cross site scripting file to accommodate these and the slack scripts.
