1.原型的理解沒(méi)有問(wèn)題。不是每個(gè)對(duì)象都有prototype屬性。原型是相對(duì)實(shí)例而言的，指向?qū)嵗龢?gòu)造函數(shù)的prototype屬性。

2.不矛盾。原型是相對(duì)于實(shí)例而言的，每個(gè)對(duì)象都有原型，但不是每個(gè)對(duì)象都有prototype屬性，構(gòu)造函數(shù)才有。

3.實(shí)例訪問(wèn)原型可通過(guò)__proto__

DOM事件既有同步有也異步。

同步

比如如鼠標(biāo)事件

我們都知道macrotask執(zhí)行完后，需要檢查有沒(méi)有microtask，如果有則執(zhí)行microtask，之后才會(huì)執(zhí)行macrotask。那么我只要知道promise回調(diào)在什么時(shí)候執(zhí)行，就知道這是個(gè)異步的還是同步的。

舉個(gè)栗子
http://jsfiddle.net/631807682...

異步

比如load事件

W3文檔

Events may be dispatched either synchronously or asynchronously.

Events which are synchronous (sync events) are treated as if they are in a virtual queue in a first-in-first-out model, ordered by sequence of temporal occurrence with respect to other events, to changes in the DOM, and to user interaction. Each event in this virtual queue is delayed until the previous event has completed its propagation behavior, or been canceled. Some sync events are driven by a specific device or process, such as mouse button events. These events are governed by the event order algorithms defined for that set of events, and user agents will dispatch these events in the defined order.

Events which are asynchronous (async events) may be dispatched as the results of the action are completed, with no relation to other events, to other changes in the DOM, nor to user interaction.

你將loading定義為數(shù)組，然后loading:this.loading[params.index],你在根據(jù)點(diǎn)擊傳入的params.index來(lái)改變loading數(shù)組對(duì)應(yīng)的值不就好了

我猜你X軸是類(lèi)目軸，根據(jù)官網(wǎng)說(shuō)法，類(lèi)目軸的data中，二維數(shù)組的的第一項(xiàng)代表索引，而非x軸的值

=================================
忘了說(shuō)解決方案，把axis.type改為value就好了

bottom: 父元素的高度

router.get('/', function(req, res, next) {

res.render('news/news', { title: 'Express' });
});

router.use(express.static(path.join(__dirname, '../public')));

router.get('/message-1',function(req,res){

res.render("news/news-message/message-1",{title:"Express"})
});

去下載chrome的這個(gè)插件就好了

說(shuō)你的.fullpage不是一個(gè)方法， 對(duì)一下括號(hào)，看看是不是少。一般都是這種情況

應(yīng)該是說(shuō)，頁(yè)面直接由后端完整給出吧。（完全不經(jīng)前端 js 邏輯的加工）

name 命名有問(wèn)題。變量Role是什么？

官方答案在此

receiver(Book)其實(shí)就是函數(shù)的一個(gè)參數(shù)而已，所以用struct就會(huì)有復(fù)制且不能修改屬性
反過(guò)來(lái)看，用pointer，那么book就有被函數(shù)修改的風(fēng)險(xiǎn)

可能border-radius,transform,transform-origin屬性存在一定的兼容性問(wèn)題，必須要加上瀏覽器廠標(biāo)。

.circle2 {
  ...
 -ms-border-radius: 50%;
 -moz-border-radius: 50%;
 -webkit-border-radius: 50%;
 -o-border-radius: 50%;
 border-radius: 50%;
 
 -ms-transform: translateX(-50%);
 -moz-transform: translateX(-50%);
 -webkit-transform: translateX(-50%);
 -o-transform: translateX(-50%);
 transform: translateX(-50%);
   
}

可以判斷登錄有沒(méi)有成功，如果登錄成功記錄一個(gè)狀態(tài)值，用localstorage來(lái)存儲(chǔ)，默認(rèn)是false，登錄成功為true,返回的時(shí)候判斷這個(gè)值是否為false，如果是true狀態(tài)返回就直接跳轉(zhuǎn)到A

:style="{background: 'url(' + item + ')'}"

這個(gè)是chrome的可以參考一下。

你這個(gè)需求明顯與瀏覽器有關(guān)，必然存在兼容問(wèn)題。
