2388 // description: | |
2389 // JavaScript has no threads, and even if it did, threads a

2390 // Deferreds are a way of abstracting non-blocking events,
such as the | |
2391 // final response to an XMLHttpRequest. Deferreds create a
promise to | |
2392 // return a response a some point in the future and an easy
way to | |
2393 // register your interest in receiving that response. | |
2394 // | |
2395 // The most important methods for Deffered users are: | |
2396 // | |
2397 // * addCallback(handler) | |
2398 // * addErrback(handler) | |
2399 // * callback(result) | |
2400 // * errback(result) | |
2401 // | |
2402 // In general, when a function returns a Deferred, users th
en "fill | |
2403 // in" the second half of the contract by registering callb
acks and | |
2404 // error handlers. You may register as many callback and er
rback | |
2405 // handlers as you like and they will be executed in the or
der | |
2406 // registered when a result is provided. Usually this resul
t is | |
2407 // provided as the result of an asynchronous operation. The
code | |
2408 // "managing" the Deferred (the code that made the promise
to provide | |
2409 // an answer later) will use the callback() and errback() m
ethods to | |
2410 // communicate with registered listeners about the result o
f the | |
2411 // operation. At this time, all registered result handlers
are called | |
2412 // *with the most recent result value*. | |
2413 // | |
2414 // Deferred callback handlers are treated as a chain, and e
ach item in | |
2415 // the chain is required to return a value that will be fed
into | |
2416 // successive handlers. The most minimal callback may be re
gistered | |
2417 // like this: | |
2418 // | |
2419 // | var d = new dojo.Deferred(); | |
2420 // | d.addCallback(function(result){ return result; }
); | |
2421 // | |
2422 // Perhaps the most common mistake when first using Deferre
ds is to | |
2423 // forget to return a value (in most cases, the value you w
ere | |
2424 // passed). | |
2425 // | |
2426 // The sequence of callbacks is internally represented as a
list of | |
2427 // 2-tuples containing the callback/errback pair. For exam
ple, the | |
2428 // following call sequence: | |
2429 // | |
2430 // | var d = new dojo.Deferred(); | |
2431 // | d.addCallback(myCallback); | |
2432 // | d.addErrback(myErrback); | |
2433 // | d.addBoth(myBoth); | |
2434 // | d.addCallbacks(myCallback, myErrback); | |
2435 // | |
2436 // is translated into a Deferred with the following interna
l | |
2437 // representation: | |
2438 // | |
2439 // | [ | |
2440 // | [myCallback, null], | |
2441 // | [null, myErrback], | |
2442 // | [myBoth, myBoth], | |
2443 // | [myCallback, myErrback] | |
2444 // | ] | |
2445 // | |
2446 // The Deferred also keeps track of its current status (fir
ed). Its | |
2447 // status may be one of three things: | |
2448 // | |
2449 // * -1: no value yet (initial condition) | |
2450 // * 0: success | |
2451 // * 1: error | |
2452 // | |
2453 // A Deferred will be in the error state if one of the foll
owing three | |
2454 // conditions are met: | |
2455 // | |
2456 // 1. The result given to callback or errback is "i
nstanceof" Error | |
2457 // 2. The previous callback or errback raised an ex
ception while | |
2458 // executing | |
2459 // 3. The previous callback or errback returned a v
alue | |
2460 // "instanceof" Error | |
2461 // | |
2462 // Otherwise, the Deferred will be in the success state. Th
e state of | |
2463 // the Deferred determines the next element in the callback
sequence | |
2464 // to run. | |
2465 // | |
2466 // When a callback or errback occurs with the example defer
red chain, | |
2467 // something equivalent to the following will happen (imagi
ne | |
2468 // that exceptions are caught and returned): | |
2469 // | |
2470 // | // d.callback(result) or d.errback(result) | |
2471 // | if(!(result instanceof Error)){ | |
2472 // | result = myCallback(result); | |
2473 // | } | |
2474 // | if(result instanceof Error){ | |
2475 // | result = myErrback(result); | |
2476 // | } | |
2477 // | result = myBoth(result); | |
2478 // | if(result instanceof Error){ | |
2479 // | result = myErrback(result); | |
2480 // | }else{ | |
2481 // | result = myCallback(result); | |
2482 // | } | |
2483 // | |
2484 // The result is then stored away in case another step is a
dded to the | |
2485 // callback sequence. Since the Deferred already has a
value | |
2486 // available, any new callbacks added will be called immedi
ately. | |
2487 // | |
2488 // There are two other "advanced" details about this implem
entation | |
2489 // that are useful: | |
2490 // | |
2491 // Callbacks are allowed to return Deferred instances thems
elves, so | |
2492 // you can build complicated sequences of events with ease. | |
2493 // | |
2494 // The creator of the Deferred may specify a canceller. Th
e canceller | |
2495 // is a function that will be called if Deferred.cancel is
called | |
2496 // before the Deferred fires. You can use this to implement
clean | |
2497 // aborting of an XMLHttpRequest, etc. Note that cancel wil
l fire the | |
2498 // deferred with a CancelledError (unless your canceller re
turns | |
2499 // another kind of error), so the errbacks should be prepar
ed to | |
2500 // handle that error for cancellable Deferreds. | |
2501 // example: | |
2502 // | var deferred = new dojo.Deferred(); | |
2503 // | setTimeout(function(){ deferred.callback({success: true}
); }, 1000); | |
2504 // | return deferred; | |
2505 // example: | |
2506 // Deferred objects are often used when making code asynchr
onous. It | |
2507 // may be easiest to write functions in a synchronous manne
r and then | |
2508 // split code using a deferred to trigger a response to a l
ong-lived | |
2509 // operation. For example, instead of register a callback f
unction to | |
2510 // denote when a rendering operation completes, the functio
n can | |
2511 // simply return a deferred: | |
2512 // | |
2513 // | // callback style: | |
2514 // | function renderLotsOfData(data, callback){ | |
2515 // | var success = false | |
2516 // | try{ | |
2517 // | for(var x in data){ | |
2518 // | renderDataitem(data[x]); | |
2519 // | } | |
2520 // | success = true; | |
2521 // | }catch(e){ } | |
2522 // | if(callback){ | |
2523 // | callback(success); | |
2524 // | } | |
2525 // | } | |
2526 // | |
2527 // | // using callback style | |
2528 // | renderLotsOfData(someDataObj, function(success){ | |
2529 // | // handles success or failure | |
2530 // | if(!success){ | |
2531 // | promptUserToRecover(); | |
2532 // | } | |
2533 // | }); | |
2534 // | // NOTE: no way to add another callback here!! | |
2535 // example: | |
2536 // Using a Deferred doesn't simplify the sending code any,
but it | |
2537 // provides a standard interface for callers and senders al
ike, | |
2538 // providing both with a simple way to service multiple cal
lbacks for | |
2539 // an operation and freeing both sides from worrying about
details | |
2540 // such as "did this get called already?". With Deferreds,
new | |
2541 // callbacks can be added at any time. | |
2542 // | |
2543 // | // Deferred style: | |
2544 // | function renderLotsOfData(data){ | |
2545 // | var d = new dojo.Deferred(); | |
2546 // | try{ | |
2547 // | for(var x in data){ | |
2548 // | renderDataitem(data[x]); | |
2549 // | } | |
2550 // | d.callback(true); | |
2551 // | }catch(e){ | |
2552 // | d.errback(new Error("rendering f
ailed")); | |
2553 // | } | |
2554 // | return d; | |
2555 // | } | |
2556 // | |
2557 // | // using Deferred style | |
2558 // | renderLotsOfData(someDataObj).addErrback(functio
n(){ | |
2559 // | promptUserToRecover(); | |
2560 // | }); | |
2561 // | // NOTE: addErrback and addCallback both return
the Deferred | |
2562 // | // again, so we could chain adding callbacks or
save the | |
2563 // | // deferred for later should we need to be notif
ied again. | |
2564 // example: | |
2565 // In this example, renderLotsOfData is syncrhonous and so
both | |
2566 // versions are pretty artificial. Putting the data display
on a | |
2567 // timeout helps show why Deferreds rock: | |
2568 // | |
2569 // | // Deferred style and async func | |
2570 // | function renderLotsOfData(data){ | |
2571 // | var d = new dojo.Deferred(); | |

5853 dojo.query() architectural overview: | |
5854 | |
5855 dojo.query is a relatively full-featured CSS3 query library. It
is | |
5856 designed to take any valid CSS3 selector and return the nodes ma
tching | |
5857 the selector. To do this quickly, it processes queries in severa
l | |
5858 steps, applying caching where profitable. | |
5859 | |
5860 The steps (roughly in reverse order of the way they appear in th
e code): | |
5861 1.) check to see if we already have a "query dispatcher" | |
5862 - if so, use that with the given parameterizatio
n. Skip to step 4. | |
5863 2.) attempt to determine which branch to dispatch the qu
ery to: | |
5864 - JS (optimized DOM iteration) | |
5865 - xpath (for browsers that support it and where
it's fast) | |
5866 - native (not available in any browser yet) | |
5867 3.) tokenize and convert to executable "query dispatcher
" | |
5868 - this is where the lion's share of the complexi
ty in the | |
5869 system lies. In the DOM version, the query dis
patcher is | |
5870 assembled as a chain of "yes/no" test function
s pertaining to | |
5871 a section of a simple query statement (".blah:
nth-child(odd)" | |
5872 but not "div div", which is 2 simple statement
s). Individual | |
5873 statement dispatchers are cached (to prevent r
e-definition) | |
5874 as are entire dispatch chains (to make re-exec
ution of the | |
5875 same query fast) | |
5876 - in the xpath path, tokenization yields a conca
tenation of | |
5877 parameterized xpath selectors. As with the DOM
version, both | |
5878 simple selector blocks and overall evaluators
are cached to | |
5879 prevent re-defintion | |
5880 4.) the resulting query dispatcher is called in the pass
ed scope (by default the top-level document) | |
5881 - for DOM queries, this results in a recursive,
top-down | |
5882 evaluation of nodes based on each simple query
section | |
5883 - xpath queries can, thankfully, be executed in
one shot | |
5884 5.) matched nodes are pruned to ensure they are unique | |

6926 // | |
6927 // Supported Selectors: | |
6928 // -------------------- | |
6929 // | |
6930 // dojo.query() supports a rich set of CSS3 selecto
rs, including: | |
6931 // | |
6932 // * class selectors (e.g., `.foo`) | |
6933 // * node type selectors like `span` | |
6934 // * ` ` descendant selectors | |
6935 // * `>` child element selectors | |
6936 // * `#foo` style ID selectors | |
6937 // * `*` universal selector | |
6938 // * `~`, the immediately preceeded-by sibl
ing selector | |
6939 // * `+`, the preceeded-by sibling selector | |
6940 // * attribute queries: | |
6941 // | * `[foo]` attribute presence sel
ector | |
6942 // | * `[foo='bar']` attribute value
exact match | |
6943 // | * `[foo~='bar']` attribute value
list item match | |
6944 // | * `[foo^='bar']` attribute start
match | |
6945 // | * `[foo$='bar']` attribute end m
atch | |
6946 // | * `[foo*='bar']` attribute subst
ring match | |
6947 // * `:first-child`, `:last-child` position
al selectors | |
6948 // * `:empty` content emtpy selector | |
6949 // * `:empty` content emtpy selector | |
6950 // * `:checked` pseudo selector | |
6951 // * `:nth-child(n)`, `:nth-child(2n+1)` st
yle positional calculations | |
6952 // * `:nth-child(even)`, `:nth-child(odd)`
positional selectors | |
6953 // * `:not(...)` negation pseudo selectors | |
6954 // | |
6955 // Any legal combination of these selectors will wo
rk with | |
6956 // `dojo.query()`, including compound selectors (",
" delimited). | |
6957 // Very complex and useful searches can be construc
ted with this | |
6958 // palette of selectors and when combined with func
tions for | |
6959 // maniplation presented by dojo.NodeList, many typ
es of DOM | |
6960 // manipulation operations become very straightforw
ard. | |
6961 // | |
6962 // Unsupported Selectors: | |
6963 // ---------------------- | |
6964 // | |
6965 // While dojo.query handles many CSS3 selectors, so
me fall outside of | |
6966 // what's resaonable for a programmatic node queryi
ng engine to | |
6967 // handle. Currently unsupported selectors include: | |
6968 // | |
6969 // * namespace-differentiated selectors of
any form | |
6970 // * all `::` pseduo-element selectors | |
6971 // * certain pseduo-selectors which don't g
et a lot of day-to-day use: | |
6972 // | * `:root`, `:lang()`, `:target`,
`:focus` | |
6973 // * all visual and state selectors: | |
6974 // | * `:root`, `:active`, `:hover`,
`:visisted`, `:link`, | |
6975 // `:enabled`, `:disabled` | |
6976 // * `:*-of-type` pseudo selectors | |
6977 // | |
6978 // dojo.query and XML Documents: | |
6979 // ----------------------------- | |
6980 // | |
6981 // `dojo.query` currently only supports searching X
ML documents | |
6982 // whose tags and attributes are 100% lower-case. T
his is a known | |
6983 // limitation and will [be addressed soon](http://t
rac.dojotoolkit.org/ticket/3866) | |
6984 // Non-selector Queries: | |
6985 // --------------------- | |
6986 // | |
6987 // If something other than a String is passed for t
he query, | |
6988 // `dojo.query` will return a new `dojo.NodeList` c
onstructed from | |
6989 // that parameter alone and all further processing
will stop. This | |
6990 // means that if you have a reference to a node or
NodeList, you | |
6991 // can quickly construct a new NodeList from the or
iginal by | |
6992 // calling `dojo.query(node)` or `dojo.query(list)`
. | |
6993 // | |
6994 // query: | |
6995 // The CSS3 expression to match against. For detail
s on the syntax of | |
6996 // CSS3 selectors, see <http://www.w3.org/TR/css3-s
electors/#selectors> | |
6997 // root: | |
6998 // A DOMNode (or node id) to scope the search from.
Optional. | |
6999 // returns: dojo.NodeList | |
7000 // An instance of `dojo.NodeList`. Many methods are
available on | |
7001 // NodeLists for searching, iterating, manipulating
, and handling | |
7002 // events on the matched nodes in the returned list
. | |
7003 // example: | |
7004 // search the entire document for elements with the
class "foo": | |
7005 // | dojo.query(".foo"); | |
7006 // these elements will match: | |
7007 // | <span class="foo"></span> | |
7008 // | <span class="foo bar"></span> | |
7009 // | <p class="thud foo"></p> | |
7010 // example: | |
7011 // search the entire document for elements with the
classes "foo" *and* "bar": | |
7012 // | dojo.query(".foo.bar"); | |
7013 // these elements will match: | |
7014 // | <span class="foo bar"></span> | |
7015 // while these will not: | |
7016 // | <span class="foo"></span> | |
7017 // | <p class="thud foo"></p> | |
7018 // example: | |
7019 // find `<span>` elements which are descendants of
paragraphs and | |
7020 // which have a "highlighted" class: | |
7021 // | dojo.query("p span.highlighted"); | |
7022 // the innermost span in this fragment matches: | |
7023 // | <p class="foo"> | |
7024 // | <span>... | |
7025 // | <span class="highlighted foo bar
">...</span> | |
7026 // | </span> | |
7027 // | </p> | |
7028 // example: | |
7029 // set an "odd" class on all odd table rows inside
of the table | |
7030 // `#tabular_data`, using the `>` (direct child) se
lector to avoid | |
7031 // affecting any nested tables: | |
7032 // | dojo.query("#tabular_data > tbody > tr:nth-child
(odd)").addClass("odd"); | |
7033 // example: | |
7034 // remove all elements with the class "error" from
the document | |
7035 // and store them in a list: | |
7036 // | var errors = dojo.query(".error").orphan(); | |
7037 // example: | |
7038 // add an onclick handler to every submit button in
the document | |
7039 // which causes the form to be sent via Ajax instea

8256 // description: | |
8257 // dojo.animateProperty is the foundation of most d
ojo.fx | |
8258 // animations. It takes an object of "properties" c
orresponding to | |
8259 // style properties, and animates them in parallel
over a set | |
8260 // duration. | |
8261 // | |
8262 // example: | |
8263 // A simple animation that changes the width of the
specified node. | |
8264 // | dojo.animateProperty({ | |
8265 // | node: "nodeId", | |
8266 // | properties: { width: 400 }, | |
8267 // | }).play(); | |
8268 // Dojo figures out the start value for the width a
nd converts the | |
8269 // integer specified for the width to the more expr
essive but | |
8270 // verbose form `{ width: { end: '400', units: 'px'
} }` which you | |
8271 // can also specify directly | |
8272 // | |
8273 // example: | |
8274 // Animate width, height, and padding over 2 second
s... the | |
8275 // pedantic way: | |
8276 // | dojo.animateProperty({ node: node, duration:2000
, | |
8277 // | properties: { | |
8278 // | width: { start: '200', end: '400
', unit:"px" }, | |
8279 // | height: { start:'200', end: '400
', unit:"px" }, | |
8280 // | paddingTop: { start:'5', end:'50
', unit:"px" } | |
8281 // | } | |
8282 // | }).play(); | |
8283 // Note 'paddingTop' is used over 'padding-top'. Mu
lti-name CSS properties | |
8284 // are written using "mixed case", as the hyphen is
illegal as an object key. | |
8285 // | |
8286 // example: | |
8287 // Plug in a different easing function and register
a callback for | |
8288 // when the animation ends. Easing functions accept
values between | |
8289 // zero and one and return a value on that basis. I
n this case, an | |
8290 // exponential-in curve. | |
8291 // | dojo.animateProperty({ | |
8292 // | node: "nodeId", | |
8293 // | // dojo figures out the start value | |
8294 // | properties: { width: { end: 400 } }, | |
8295 // | easing: function(n){ | |
8296 // | return (n==0) ? 0 : Math.pow(2,
10 * (n - 1)); | |
8297 // | }, | |
8298 // | onEnd: function(){ | |
8299 // | // called when the animation fin
ishes | |
8300 // | } | |
8301 // | }).play(500); // delay playing half a second | |
8302 // | |
8303 // example: | |
8304 // Like all `dojo._Animation`s, animateProperty ret
urns a handle to the | |
8305 // Animation instance, which fires the events commo
n to Dojo FX. Use `dojo.connect` | |
