require.config({	waitSeconds : 12,	paths:{		jquery : "https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery",		async : "../js/async", //alias to plugin		bootstrap : "../js/bootstrap",		fresh: "../themes/fresh",		color:"../js/color_module"	},	shim : {		'bootstrap': {deps:['jquery']}		}});require(['jquery','bootstrap'],function($, _bootstrap){		$("a").tooltip({      'selector': '',      'placement': 'top'    });    //console.log("Olof");	//return {};});require(['async!http://maps.google.com/maps/api/js?sensor=false', 'fresh'],function(){        var mapDiv = document.getElementById('map');    var map = new google.maps.Map(mapDiv, {        center: new google.maps.LatLng(37.4419, -122.1419),        zoom: 13,        mapTypeId: google.maps.MapTypeId.ROADMAP,        navigationControl: true,        navigationControlOptions: {            style: google.maps.NavigationControlStyle.SMALL        },        styles: gmapFreshStyle    }); });// require(['color'],function(color){// 	return color;// });

主要是尝试一下 requirejs

说不好的感觉 javascript 天生的缺陷 一览无余

google maps api ---> require.js plugin "async!"

bootstrap:tooltip ---> jquery + bootstrap
