在插件中传递方法参数或选项

Question

    (function ( $ ) {
        $.fn.greenify = function( options ) {
            var settings = $.extend({
                color: "#556b2f"
            }, options );

            return this.css({color: settings.color});
        };
              //TODO another function here
       if ( action === "open") {
           alert("Open!");
        }

        if ( action === "close" ) {
           alert("lose!");
        }

    }( jQuery ));

`$( "div" ).greenify({color: "orange"});`//setting of options

我明白上面的代码设置了greenify插件的选项，但我也想调用显示函数。

如何在设置选项仍然可用于 greenify 的情况下实现这种用法：

`$( "div" ).greenify("open");` 

和

$( "div" ).greenify(open,{color: "orange"});

您只需检查options 是对象还是字符串

$.fn.greenify = function(options) {
    if (typeof options === 'string') {
        if (options === 'open') {
            alert('open');
        } else if (options === 'close') {
            alert('close');
        }
    } else {

        var settings = $.extend({
            color: "#556b2f"
        }, options);

        return this.css({
            color: settings.color
        });
    }
}
