bootstrap2.js

dojo与json创建无限级树的时候,当在父结点下添加了一个新结点,我怎么让父亲结点重新调用json加载一下子结点内容.

/**
 * requireLocalization() is for loading translated bundles provided within a package in the namespace.
 * Contents are typically strings, but may be any name/value pair, represented in JSON format.
 * A bundle is structured in a program as follows:
 *
 * <package>/
 *  nls/
 *   de/
 *    mybundle.js
 *   de-at/
 *    mybundle.js
 *   en/
 *    mybundle.js
 *   en-us/
 *    mybundle.js
 *   en-gb/
 *    mybundle.js
 *   es/
 *    mybundle.js
 *  ...etc
 *
 * where package is part of the namespace as used by dojo.require().  Each directory is named for a
 * locale as specified by RFC 3066, (http://www.ietf.org/rfc/rfc3066.txt), normalized in lowercase.
 *
 * For a given locale, string bundles will be loaded for that locale and all general locales above it, as well
 * as a system-specified fallback.  For example, "de_at" will also load "de" and "en".  Lookups will traverse
 * the locales in this order.  A build step can preload the bundles to avoid data redundancy and extra network hits.
 *
 * @param modulename package in which the bundle is found
 * @param bundlename bundle name, typically the filename without the '.js' suffix
 * @param locale the locale to load (optional)  By default, the browser's user locale as defined
 *	in dojo.locale
