I wanted to share a small piece of html/javascript that I wrote today to be able to keep track of multiple account balances at once. Save this under webapps/root/accountBalances.html :
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8"/>
<title>Nxt Account Balances</title>
<style type="text/css">
table {border-collapse: collapse;}
td {padding: 5px;}
.result {white-space: pre; font-family: monospace;}
</style>
<script type="text/javascript">
function getAccountBalances(form) {
var accounts = form.elements["accounts"].value.split('\n');
var balance = 0;
var result = '<table><tr><th>account</th><th>balance</th></tr>';
for (i = 0; i < accounts.length; i++) {
account = accounts[i].trim();
if (account != '') {
var accountBalance = getBalance(accounts[i]) 100;
result += '<tr><td>';
result += account;
result += ':</td><td>';
result += formatAmount(accountBalance);
result += '</td></tr>';
balance += accountBalance;
}
}
result += '<tr><td>total:</td><td>';
result += formatAmount(balance);
result += '</td></tr></table>';
form.getElementsByClassName("result")[0].innerHTML = result;
return false;
}
function getBalance(account) {
var request = new XMLHttpRequest();
request.open("GET", '/nxt?requestType=getBalance&account=' + account, false);
request.send();
return JSON.parse(request.responseText).balance;
}
function formatAmount(amount) {
var digits=[], formattedAmount = "", i;
do {
digits[digits.length] = amount % 10;
amount = Math.floor(amount 10);
} while (amount > 0);
for (i = 0; i < digits.length; i++) {
if (i > 0 && i % 3 == 0) {
formattedAmount = "'" + formattedAmount;
}
formattedAmount = digits[i] + formattedAmount;
}
return formattedAmount;
}
</script>
</head>
<body>
<b>Get Account Balances:</b><br/>
<form action="/nxt" method="GET" onsubmit="return getAccountBalances(this);">
<table>
<tr>
<td>Accounts:</td>
<td><textarea name="accounts" style="width: 100%; height: auto;" rows="6"></textarea></td>
</tr>
<tr>
<td colspan="2"><input type="submit" value="submit"/></td>
</tr>
</table>
<div class="result"></div>
</form>
</body>
</html>
. Enter your account numbers, one per line, and click submit. If you created several accounts in order to purchase aliases, hallmark servers, mine, etc, I find it useful to be able to check all your balances on one page.
