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.

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> + // + // 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 + // 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.
