// description:
// Modules are loaded via dojo.require by using one of two loaders: the normal loader
// and the xdomain loader. The xdomain loader is used when dojo was built with a
// custom build that specified loader=xdomain and the module lives on a modulePath
// that is a whole URL, with protocol and a domain. The versions of Dojo that are on
// the Google and AOL CDNs use the xdomain loader.
- //
+ //
// If the module is loaded via the xdomain loader, it is an asynchronous load, since
// the module is added via a dynamically created script tag. This
- // means that dojo.require() can return before the module has loaded. However, this
+ // means that dojo.require() can return before the module has loaded. However, this
// should only happen in the case where you do dojo.require calls in the top-level
// HTML page, or if you purposely avoid the loader checking for dojo.require
// dependencies in your module by using a syntax like dojo["require"] to load the module.
- //
+ //
// Sometimes it is useful to not have the loader detect the dojo.require calls in the
// module so that you can dynamically load the modules as a result of an action on the
// page, instead of right at module load time.
- //
+ //
// Also, for script blocks in an HTML page, the loader does not pre-process them, so
// it does not know to download the modules before the dojo.require calls occur.
- //
+ //
// So, in those two cases, when you want on-the-fly module loading or for script blocks
// in the HTML page, special care must be taken if the dojo.required code is loaded
// asynchronously. To make sure you can execute code that depends on the dojo.required
// modules, be sure to add the code that depends on the modules in a dojo.addOnLoad()
// callback. dojo.addOnLoad waits for all outstanding modules to finish loading before
- // executing. Example:
- //
- // | <script type="text/javascript">
- // | dojo.require("foo");
- // | dojo.require("bar");
- // | dojo.addOnLoad(function(){
- // | //you can now safely do something with foo and bar
- // | });
- // | </script>
- //
+ // executing.
+ //
// This type of syntax works with both xdomain and normal loaders, so it is good
// practice to always use this idiom for on-the-fly code loading and in HTML script
// blocks. If at some point you change loaders and where the code is loaded from,
// it will all still work.
- //
+ //
// More on how dojo.require
// `dojo.require("A.B")` first checks to see if symbol A.B is
// defined. If it is, it is simply returned (nothing to do).
- //
+ //
// If it is not defined, it will look for `A/B.js` in the script root
// directory.
- //
- // `dojo.require` throws an excpetion if it cannot find a file
+ //
+ // `dojo.require` throws an exception if it cannot find a file
// to load, or if the symbol `A.B` is not defined after loading.
- //
+ //
// It returns the object `A.B`, but note the caveats above about on-the-fly loading and
// HTML script blocks when the xdomain loader is loading a module.
- //
+ //
// `dojo.require()` does nothing about importing symbols into
// the current namespace. It is presumed that the caller will
- // take care of that. For example, to import all symbols into a
- // local block, you might write:
- //
+ // take care of that.
+ //
+ // example:
+ // To use dojo.require in conjunction with dojo.ready:
+ //
+ // | dojo.require("foo");
+ // | dojo.require("bar");
+ // | dojo.addOnLoad(function(){
+ // | //you can now safely do something with foo and bar
+ // | });
+ //
+ // example:
+ // For example, to import all symbols into a local block, you might write:
+ //
// | with (dojo.require("A.B")) {
// | ...
// | }
- //
