CRM 2011 – Formatting a currency using Javascript

I was looking on LinkedIn and then I saw Jamie Miley had replied and then I found my way to his blog.  He had some interesting blog entries on his site.  I saw this one Formatting Currency in Microsoft Dynamics CRM 2011 and CRM 4 in JScript.  It was a nice function to format currencies in Javascript.

I though it was useful piece of Javascript although I wondered why you would need it in CRM because you cpuld just format the field.

Still I am always looking to improve my Javascript skills and I thought it was a good example.  also you never know they might be a day when I need to format soem currency using Javascript for reasons that are not clear to me.

//Format currency in CRM jscript

//EXAMPLE USAGE
//alert(FormatAsCurrency(10000));

function FormatAsCurrency(amount) {

var i = parseFloat(amount);
if (isNaN(i)) { i = 0.00; }
var minus = '';
if (i < 0) { minus = '-'; }
i = Math.abs(i);
i = parseInt((i + .005) * 100);
i = i / 100;
s = new String(i);
if (s.indexOf('.') < 0) { s += '.00'; }
if (s.indexOf('.') == (s.length - 2)) { s += '0'; }
s = minus + s;
amount = s;
var delimiter = ","; // replace comma if other mark is desired
var a = amount.split('.', 2)
var d = a[1];
var i = parseInt(a[0]);
if (isNaN(i)) { return ''; }
var minus = '';
if (i < 0) { minus = '-'; }
i = Math.abs(i);
var n = new String(i);
var a = [];
while (n.length > 3) {
var nn = n.substr(n.length - 3);
a.unshift(nn);
n = n.substr(0, n.length - 3);
}
if (n.length > 0) { a.unshift(n); }
n = a.join(delimiter);
if (d.length < 1) { amount = n; }
else { amount = n + '.' + d; }
amount = minus + amount;

return "$" + amount;

 

}
