formatting - How can I format numbers as dollars currency string in JavaScript? -


i format price in javascript.
i'd function takes float argument , returns string formatted this:

"$ 2,500.00"

what's best way this?

you can use:

  var profits=2489.8237   profits.tofixed(3) //returns 2489.824 (round up)   profits.tofixed(2) //returns 2489.82   profits.tofixed(7) //returns 2489.8237000 (padding)

then can add sign of '$'.

if require ',' thousand can use:

number.prototype.formatmoney = function(c, d, t){ var n = this,      c = isnan(c = math.abs(c)) ? 2 : c,      d = d == undefined ? "." : d,      t = t == undefined ? "," : t,      s = n < 0 ? "-" : "",      = string(parseint(n = math.abs(number(n) || 0).tofixed(c))),      j = (j = i.length) > 3 ? j % 3 : 0;    return s + (j ? i.substr(0, j) + t : "") + i.substr(j).replace(/(\d{3})(?=\d)/g, "$1" + t) + (c ? d + math.abs(n - i).tofixed(c).slice(2) : "");  };

and use with:

(123456789.12345).formatmoney(2, '.', ',');

if you're going use '.' , ',', can leave them off method call, , method default them you.

(123456789.12345).formatmoney(2);

if culture has 2 symbols flipped (i.e. europeans), paste on following 2 lines in formatmoney method:

    d = d == undefined ? "," : d,      t = t == undefined ? "." : t,

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
