Check.NOT_LOADED

Indicates a script is not yet loaded, or must not be loaded, depending on the Check function being used...

Notes

This constant can be used in two scenarios:

Checking if a script is not yet loaded via Check.has() and Check.versionOf() functions
Requiring a script not to be loaded via the Check.doWhen() and Check.required() functions

Examples

Checking if a script is not loaded...

if (Check.versionOf("foo.js") == Check.NOT_LOADED) {
	// foo.js is not loaded
}
 
// this might cause foo.js to be autoloaded...
if (Check.has("foo.js") == Check.NOT_LOADED) {
	// tried to load foo.js but did not succeed
} else {
	// foo.js autoloaded or was already loaded
}
 
// this will prevent foo.js from being autoloaded...
if (Check.has("foo.js", Check.NOT_LOADED)) {
	// foo.js is not loaded
} else {
	// foo.js was already loaded
}

Requiring a script to be not loaded...

var dependencies = {
	"bar.js": Check.ANY_VERSION,
	"foo.js": Check.NOT_LOADED
};
 
// the task will only run if bar.js is loaded and foo.js is *not* loaded
Check.doWhen(dependencies, self, task);
 
// will throw an error if bar.js is not loaded or foo.js is loaded
Check.required(dependencies, self);

Dependency Descriptor Object — Define one or more dependencies for your script...
Check() — Perform a soft-check to see if a dependency is available...
- Check.basePath — The base path to the folder that contains the APIs folder...
- Check.paths[] — Define one or more folder paths to enable autoloading...
- Check.doWhen() — Perform a task when dependencies become available.
- Check.has() — Check if a dependency is available, try and load it if not, return availability state...
- Check.LAZY_LOAD — Disable autoloading during a dependency check...
- Check.required() — Thrown a descriptive error if dependency check fails...
- Check.NOT_LOADED — Indicates a script is not yet loaded, or must not be loaded, depending on the Check function being used...
- Check.ANY_VERSION — Skip version checking for a dependency check...
- Check.provide() — Indicate a file is now available.
- Check.versionOf() — Check the version of a dependency.
Self Descriptor Object — Define the filename and version of your script...
