javascript - 如何访问 jQuery 插件功能？

Question

所以我有一个 jQuery 插件，它工作得非常好。在这个插件中，有一个 HTML 按钮分配给了 togglePushy(); 方法，并且它工作得很好。

但是，我想从 Javascript 控制台使用此方法。问题是如果输入 $.togglePushy(); 它说它是未定义的。我怎样才能访问它？

$(function() {
    var pushy = $('.pushy'), //menu css class
        body = $('body'),
        container = $('#container'), //container css class
        push = $('.push'), //css class to add pushy capability
        siteOverlay = $('.site-overlay'), //site overlay
        pushyClass = "pushy-left pushy-open", //menu position & menu open class
        pushyActiveClass = "pushy-active", //css class to toggle site overlay
        containerClass = "container-push", //container open class
        pushClass = "push-push", //css class to add pushy capability
        menuBtn = $('.menu-btn, .pushy a'), //css classes to toggle the menu
        menuSpeed = 200, //jQuery fallback menu speed
        menuWidth = pushy.width() + "px"; //jQuery fallback menu width

    function togglePushy(){
        body.toggleClass(pushyActiveClass); //toggle site overlay
        pushy.toggleClass(pushyClass);
        container.toggleClass(containerClass);
        push.toggleClass(pushClass); //css class to add pushy capability
    }

    function openPushyFallback(){
        body.addClass(pushyActiveClass);
        pushy.animate({left: "0px"}, menuSpeed);
        container.animate({left: menuWidth}, menuSpeed);
        push.animate({left: menuWidth}, menuSpeed); //css class to add pushy capability
    }

    function closePushyFallback(){
        body.removeClass(pushyActiveClass);
        pushy.animate({left: "-" + menuWidth}, menuSpeed);
        container.animate({left: "0px"}, menuSpeed);
        push.animate({left: "0px"}, menuSpeed); //css class to add pushy capability
    }

    menuBtn.click(function() {
        togglePushy();
    });
});

也许你可以将 togglePushy 更改为如下所示:

$.togglePushy = function(){ 
    body.toggleClass(pushyActiveClass); //toggle site overlay
    pushy.toggleClass(pushyClass);
    container.toggleClass(containerClass);
    push.toggleClass(pushClass); //css class to add pushy capability
}

现在您应该能够通过 $.togglePushy() 访问它
