Question

我正试图想办法让这个Meny JS菜单打开onClick而不是鼠标悬停。我已经尝试在js中注释掉鼠标悬停功能，以允许mousedown和mouseup优先，但它只是完全杀死了这个功能。非常感谢你们所能提供的任何帮助/洞察力。

我确信解决方案存在于此部分 - 见下文：

        /**
         * The contents element which gets pushed aside while
         * Meny is open.
         */
        function setupContents() {
            // Shorthand
            var style = dom.contents.style;

            originalStyles.contents = style.cssText;

            if( supports3DTransforms ) {
                style[ Meny.prefix( 'transform' ) ] = contentsTransformClosed;
                style[ Meny.prefix( 'transformOrigin' ) ] = contentsTransformOrigin;
                style[ Meny.prefix( 'transition' ) ] = 'all ' + config.transitionDuration +' '+ config.transitionEasing;
            }
            else {
                style.position = style.position.match( /relative|absolute|fixed/gi ) ? style.position : 'relative';
                Meny.extend( style, contentsStyleClosed );
            }
        }

        /**
         * Attaches all input event listeners.
         */
        function bindEvents() {

            if( 'ontouchstart' in window ) {
                if( config.touch ) {
                    Meny.bindEvent( document, 'touchstart', onTouchStart );
                    Meny.bindEvent( document, 'touchend', onTouchEnd );
                }
                else {
                    Meny.unbindEvent( document, 'touchstart', onTouchStart );
                    Meny.unbindEvent( document, 'touchend', onTouchEnd );
                }
            }

            if( config.mouse ) {
                Meny.bindEvent( document, 'mousedown', onMouseDown );
                Meny.bindEvent( document, 'mouseup', onMouseUp );
                Meny.bindEvent( document, 'mousemove', onMouseMove );
            }
            else {
                Meny.unbindEvent( document, 'mousedown', onMouseDown );
                Meny.unbindEvent( document, 'mouseup', onMouseUp );
                Meny.unbindEvent( document, 'mousemove', onMouseMove );
            }
        }

解决方案是将threshold参数设置为0，将mouse设置为false，然后使用jQuery click处理程序运行{{ 1}}：

meny.open()

Example.

注意：在我将var meny = Meny.create({ ... threshold: 0, mouse: false }); $(".meny-arrow").click(function(){ meny.open(); }); $(".meny").click(function(){ meny.close(); }); $(".contents").click(function(){ meny.close(); });代码内嵌到所有内容之前，这对我不起作用。当我在外部链接它时，它不起作用。因此，我建议您直接在脚本中修改Meny.js和threshold参数，而不是使用mouse函数覆盖。
