jq.js

/**
 * General-purpose jQuery wrapper. Simply pass the plugin name as the expression.
 *
 * It is possible to specify a default set of parameters for each jQuery plugin.
 * Under the jq key, namespace each plugin by that which will be passed to ui-jq.
 * Unfortunately, at this time you can only pre-define the first parameter.
 * @example { jq : { datepicker : { showOn:'click' } } }
 *
 * @param ui-jq {string} The $elm.[pluginName]() to call.
 * @param [ui-options] {mixed} Expression to be evaluated and passed as options to the function
 *     Multiple parameters can be separated by commas
 * @param [ui-refresh] {expression} Watch expression and refire plugin on changes
 *
 * @example <input ui-jq="datepicker" ui-options="{showOn:'click'},secondParameter,thirdParameter" ui-refresh="iChange">
