插件已初始化了，能不能再次修改该插件某值？

[icemanpro]

插件类似
(function ( $ ) {
$.fn.greenify = function( options ) {

// This is the easiest way to have default options.
var settings = $.extend({
// These are the defaults.
color: "#556b2f",
backgroundColor: "white"
}, options );

// Greenify the collection based on the settings variable.
return this.css({
color: settings.color,
backgroundColor: settings.backgroundColor
});

};

}( jQuery ));

/* Example usage */
$( "div" ).greenify({
color: "orange"
});

在已初始化后，如何再修改“ backgroundColor ”的值？

$("div").greenify("bacgroundColor","#aaaaaa");
这样吧
