dateTimeFu adds a new method "format" to the built in JavaScript Date object
Date.format() takes one argument, a formatting mask
you can use a pre-defined formatting mask or an inline mask. you can also define new re-usable masks
var now = new Date();
now.format("shortDate"); // ouputs: 7/1/10
now.format("mm/dd/yyyy"); // outputs: 07/01/2010
| Name | Mask | Example |
|---|---|---|
| default | ddd mmm dd yyyy HH:MM:ss | Sat Jun 09 2010 17:46:21 |
| shortDate | m/d/yy | 6/9/07 |
| mediumDate | mmm d, yyyy | Jun 9, 2010 |
| longDate | mmmm d, yyyy | June 9, 2010 |
| fullDate | dddd, mmmm d, yyyy | Saturday, June 9, 2010 |
| shortTime | h:MM TT | 5:46 PM |
| mediumTime | h:MM:ss TT | 5:46:21 PM |
| longTime | h:MM:ss TT Z | 5:46:21 PM EST |
| isoDate | yyyy-mm-dd | 2010-06-09 |
| isoTime | HH:MM:ss | 17:46:21 |
| isoDateTime | yyyy-mm-dd'T'HH:MM:ss | 2010-06-09T17:46:21 |
| isoUtcDateTime | UTC:yyyy-mm-dd'T'HH:MM:ss'Z' | 2010-06-09T22:46:21Z |

linqFu is adds the JSLINQ project which is a pure javascript implementation of gasp Microsoft's LINQ query language. it's very usefull for quickly querying JSON objects. ###simple Select var sample = fu.linq(sampleData). Select(function (item) {return item.FirstName;}); output: {"items":["Chris","Kate","Josh","John","Steve","Katie","Dirk","Chris","Bernard","Kate"]} ###simple Select with OrderBy var sample = fu.linq(sampleData). Select(function (item) {return item.FirstName;}). OrderBy(function (item) {return item;}); output: {"items":["Bernard","Chris","Chris","Dirk","John","Josh","Kate","Kate","Katie","Steve"]} ###simple Where var sample = fu.linq(sampleData).Where(function (item) {return item.FirstName == "Chris";}); output: [ {"ID":1,"FirstName":"Chris","LastName":"Pearson","BookIDs":[1001,1002,1003]}, {"ID":8,"FirstName":"Chris","LastName":"Stevenson","BookIDs":[4001,4002,4003]} ] ###For the Full JSLINQ Demo and API implementation goto @ [http://maraksquires.com/JSLINQ/](http://maraksquires.com/JSLINQ/)
