如何将javascript函数转换为angular js

我使用了一个插件，使用这个语句块来显示菜单，现在我在angular js中使用它。

(function(window) {
	'use strict';
	var support = { animations : Modernizr.cssanimations },
		animEndEventNames = { 'WebkitAnimation' : 'webkitAnimationEnd', 'OAnimation' : 'oAnimationEnd', 'msAnimation' : 'MSAnimationEnd', 'animation' : 'animationend' },
		animEndEventName = animEndEventNames[ Modernizr.prefixed( 'animation' ) ],
		onEndAnimation = function( el, callback ) {
			var onEndCallbackFn = function( ev ) {
				if( support.animations ) {
					if( ev.target != this ) return;
					this.removeEventListener( animEndEventName, onEndCallbackFn );
				}
				if( callback && typeof callback === 'function' ) { callback.call(); }
			};
			if( support.animations ) {
				el.addEventListener( animEndEventName, onEndCallbackFn );
			}
			else {
				onEndCallbackFn();
			}
		};
	function extend( a, b ) {
		for( var key in b ) { 
			if( b.hasOwnProperty( key ) ) {
				a[key] = b[key];
			}
		}
		return a;
	}
	function MLMenu(el, options) {
		this.el = el;
		this.options = extend( {}, this.options );
		extend( this.options, options );
		
		// the menus (<ul>´s)
		this.menus = [].slice.call(this.el.querySelectorAll('.menu__level'));
		// index of current menu
		this.current = 0;
		this._init();
	}
	MLMenu.prototype.options = {
		// show breadcrumbs
		breadcrumbsCtrl : true,
		// initial breadcrumb text
		initialBreadcrumb : 'all',
		// show back button
		backCtrl : true,
		// delay between each menu item sliding animation
		itemsDelayInterval : 60,
		// direction 
		direction : 'r2l',
		// callback: item that doesn´t have a submenu gets clicked
		// onItemClick([event], [inner HTML of the clicked item])
		onItemClick : function(ev, itemName) { return false; }
	};
	MLMenu.prototype._init = function() {
		// iterate the existing menus and create an array of menus, more specifically an array of objects where each one holds the info of each menu element and its menu items
		this.menusArr = [];
		var self = this;
		this.menus.forEach(function(menuEl, pos) {
			var menu = {menuEl : menuEl, menuItems : [].slice.call(menuEl.querySelectorAll('.menu__item'))};

			this.backCtrl = document.createElement('button');
			this.backCtrl.className = 'menu__back menu__back--hidden';

			this.backCtrl.innerHTML = '<span class="icon icon--arrow-left"></span>';
			this.el.insertBefore(this.backCtrl, this.el.firstChild);
		}
		
		
		// create breadcrumbs
		if( self.options.breadcrumbsCtrl ) {
			this.breadcrumbsCtrl = document.createElement('nav');
			this.breadcrumbsCtrl.className = 'menu__breadcrumbs';
			this.el.insertBefore(this.breadcrumbsCtrl, this.el.firstChild);
			// add initial breadcrumb
			this._addBreadcrumb(0);
		}
		// event binding
		this._initEvents();
	};
	MLMenu.prototype._initEvents = function() {
		var self = this;
		for(var i = 0, len = this.menusArr.length; i < len; ++i) {
			this.menusArr[i].menuItems.forEach(function(item, pos) {
				item.querySelector('a').addEventListener('click', function(ev) { 
					var submenu = ev.target.getAttribute('data-submenu'),
						itemName = ev.target.innerHTML,
						subMenuEl = self.el.querySelector('ul[data-menu="' + submenu + '"]');
					// check if there's a sub menu for this item
					if( submenu && subMenuEl ) {
						ev.preventDefault();
						// open it
						self._openSubMenu(subMenuEl, pos, itemName);
					}
					else {
						// add class current
						var currentlink = self.el.querySelector('.menu__link--current');

						classie.add(ev.target, 'menu__link--current');
						
						// callback
						self.options.onItemClick(ev, itemName);
					}
				});
			});
		}
		
		// back navigation
		if( this.options.backCtrl ) {
			this.backCtrl.addEventListener('click', function() {
				self._back();
			});
		}
	};
	MLMenu.prototype._openSubMenu = function(subMenuEl, clickPosition, subMenuName) {
		if( this.isAnimating ) {
			return false;
		}
		this.isAnimating = true;
		
		// save "parent" menu index for back navigation

			item.style.WebkitAnimationDelay = item.style.animationDelay = isBackNavigation ? parseInt(pos * self.options.itemsDelayInterval) + 'ms' : parseInt(Math.abs(clickPosition - pos) * self.options.itemsDelayInterval) + 'ms';
		});
		// animation class
		if( this.options.direction === 'r2l' ) {
			classie.add(currentMenu, !isBackNavigation ? 'animate-outToLeft' : 'animate-outToRight');
		}
		else {
			classie.add(currentMenu, isBackNavigation ? 'animate-outToLeft' : 'animate-outToRight');	
		}
	};
	MLMenu.prototype._menuIn = function(nextMenuEl, clickPosition) {
		var self = this,
			// the current menu
			currentMenu = this.menusArr[this.current].menuEl,
			isBackNavigation = typeof clickPosition == 'undefined' ? true : false,
			// index of the nextMenuEl

			// we need to reset the classes once the last item animates in
			// the "last item" is the farthest from the clicked item
			// let's calculate the index of the farthest item
			var farthestIdx = clickPosition <= nextMenuItemsTotal/2 || isBackNavigation ? nextMenuItemsTotal - 1 : 0;
			if( pos === farthestIdx ) {

					else if( self.current === 0 && self.options.backCtrl ) {

					self.isAnimating = false;
				});
			}
		});	
		
		// animation class
		if( this.options.direction === 'r2l' ) {
			classie.add(nextMenuEl, !isBackNavigation ? 'animate-inFromRight' : 'animate-inFromLeft');
		}
		else {
			classie.add(nextMenuEl, isBackNavigation ? 'animate-inFromRight' : 'animate-inFromLeft');
		}
	};
	MLMenu.prototype._addBreadcrumb = function(idx) {
		if( !this.options.breadcrumbsCtrl ) {
			return false;
		}
		var bc = document.createElement('a');
		bc.innerHTML = idx ? this.menusArr[idx].name : this.options.initialBreadcrumb;
		this.breadcrumbsCtrl.appendChild(bc);
		var self = this;
		bc.addEventListener('click', function(ev) {
			ev.preventDefault();
			// do nothing if this breadcrumb is the last one in the list of breadcrumbs
			if( !bc.nextSibling || self.isAnimating ) {
				return false;
			}
			self.isAnimating = true;
			
			// current menu slides out
			self._menuOut();
			// next menu slides in
			var nextMenu = self.menusArr[idx].menuEl;
			self._menuIn(nextMenu);
			// remove breadcrumbs that are ahead
			var siblingNode;
			while (siblingNode = bc.nextSibling) {
				self.breadcrumbsCtrl.removeChild(siblingNode);
			}
		});
	};
	window.MLMenu = MLMenu;
})(window);

和自定义Java脚本:

(function() {
	    var menuEl = document.getElementById('ml-menu');
			mlmenu = new MLMenu(menuEl, {
				// breadcrumbsCtrl : true, // show breadcrumbs
				// initialBreadcrumb : 'all', // initial breadcrumb text
				backCtrl : false, // show back button
				// itemsDelayInterval : 60, // delay between each menu item sliding animation
				onItemClick: loadDummyData // callback: item that doesn´t have a submenu gets clicked - onItemClick([event], [inner HTML of the clicked item])
			});
		 //mobile menu toggle
		var openMenuCtrl = document.querySelector('.action--open'),
			closeMenuCtrl = document.querySelector('.action--close');
		openMenuCtrl.addEventListener('click', openMenu);
		closeMenuCtrl.addEventListener('click', closeMenu);
		function openMenu() {
			classie.add(menuEl, 'menu--open');
		}
		function closeMenu() {
			classie.remove(menuEl, 'menu--open');
		}
		// simulate grid content loading
		var gridWrapper = document.querySelector('.content');
		function loadDummyData(ev, itemName) {
			ev.preventDefault();
			closeMenu();
			gridWrapper.innerHTML = '';
			classie.add(gridWrapper, 'content--loading');
			setTimeout(function() {
				classie.remove(gridWrapper, 'content--loading');
				gridWrapper.innerHTML = '<ul class="products">' + dummyData[itemName] + '<ul>';
			}, 700);
		}
	})();

我想把下面自定义脚本的一部分转换成angular js。

mlmenu = new MLMenu(menuEl, {
				// breadcrumbsCtrl : true, // show breadcrumbs
				// initialBreadcrumb : 'all', // initial breadcrumb text
				backCtrl : false, // show back button
				// itemsDelayInterval : 60, // delay between each menu item sliding animation
				onItemClick: loadDummyData // callback: item that doesn´t have a submenu gets clicked - onItemClick([event], [inner HTML of the clicked item])
			});

我在angular中使用它，但是它有错误。

    $scope.menuEl = document.getElementById('ml-menu');
     var menuEl = document.getElementById('ml-menu'),
     mlmenu = new MLMenu(menuEl, {
                 // breadcrumbsCtrl : true, // show breadcrumbs
                 // initialBreadcrumb : 'all', // initial breadcrumb text
                 backCtrl: false, // show back button
                 // itemsDelayInterval : 60, // delay between each menu item sliding animation
                 onItemClick: $scope.loadDummyData // callback: item that doesn´t have a submenu gets clicked - onItemClick([event], [inner HTML of the clicked item])
     });
