phpMyAdmin - Bookmarklet for quickly selecting database(s) on a search string

pma-db-select-bookmarklet.js

/**
 * Will not select system databases (greyed out)
 * Works with regular expressions:
 *  '^te' -> matches 'test' database
 *  '^est' -> will NOT match 'test' database
 *
 * I created this to easily drop numerous databases
 * that are part of a large system, such as 'phabricator.'

var msg = "";

alert(msg);

Added alert noting what was selected/unselected.
