                    我用vue写的分两大步,一利用v-model,获取的内容,与邮箱后缀组成的数组遍历的内容链接成新的字符串,在页面上显示,
                    第二步是根据新组成的字符串字符串进行过滤.
                    怎么过滤不会了,
                    我想用正则,正则不知道怎么写,
                    还没有想到第二种方法,
                    你帮我看看怎么写还有其他方法吗*/

因为这里两个声明变量，a是用var 声明的局部变量，而b是全局变量
没有使用 &apos;use strict&apos; 严格模式，在严格模式下，代码就会引发ReferenceError错误，b没有定义（b is undefined），严格模式需要明确指出才能实现全局变量。

<pre><code>答：输出的是 Aurelio De Rosa 和 John Doe
原因是:在一个函数中，this的取值是看JavaScript调用方式的和定义方式，而不仅仅是定义方式。
在第一个console.log()中，getFullname()作为obj.prop的被调用对象,所以上下文指向后者，函数返回该对象的fullname,与此相反，getFullname被分配到test(),上下文指的是全局对象（window），只是因为test是被隐式设置的全局对象的属性，出于这个原因，该函数返回window的fullname

</code></pre><h4 id="3、JavaScript-window-onload和jQuery-ready-函数的区别"><a href="#3、JavaScript-window-onload和jQuery-ready-函数的区别" class="headerlink" title="3、JavaScript window.onload和jQuery ready()函数的区别"></a>3、JavaScript window.onload和jQuery ready()函数的区别</h4><pre><code>JavaScript window.onload事件和jQuery ready 函数的主要区别是
前者是要等到DOM被创建和图片、音频、视频加载完成以及外部资源加载完成，如果图片加载和媒体加载话费了大量的时间，用户就会感到定义在JavaScript window.onload 的上的代码在执行是有明显迟到。
jQuery ready()函数只需对DOM树加载等待，无需对图片或媒体加载等待，执行起来更快。使用jQuery ready()函数的另一个优势是可以在页面中多次使用它，浏览器会按在HTML里的顺序来执行它，相对于onload来说，只在单一的函数中执行。鉴于这个好处，jQuery ready函数比JavaScript window.onload好用。

    一、wxml(weixin MarkUp language) 是框架设计的一套标签语言、结合基础组件、事件系统，可以构建出页面的结构。内部主要是微信自己构建的一套组件。
    二、wxss(weixin style sheets)是一种样式语言，用于描述wxml的组件样式。
    三、js逻辑处理、网络请求
    四、json 小程序设置，如页面注册、页面标题及tabBar
    五、app.json 必须有这个文件、如果没有这个文件项目无法运行，因为微信小程序把这个文件作为配置文件入口，整个小程序的全局配置。包括页面注册、网络设置、以及小程序的window的背景色、配置导航条样式、配置默认标题。
    六、app.js 必须有这个文件、如果没有这个文件项目也会报错，这个文件创建一下就行啦，不需要我们现在写以后我们可以在这个文件中监听并处理小程序的生命周期函数、声明全局变量。
    七、app.wxss 这是个公共的样式文件。

</code></pre><h3 id="6-简述微信小程序的原理"><a href="#6-简述微信小程序的原理" class="headerlink" title="6.简述微信小程序的原理"></a>6.简述微信小程序的原理</h3><pre><code>答： 微信小程序采用JavaScript 、wxml 、wxss、三种技术进行开发，从技术讲和现有的前端开发差不多，但是深入挖掘的话有不同。
JavaScript：    首先JavaScript的代码运行在微信app中的，并不是运行在浏览器中的，因此一些h5技术的应用，需要微信app提供api支持，而这限制了h5技术的应用，且其不能称为严格的h5,可称其为伪h5，同理，微信提供的api,h5不支持或支持的不是很好。
wxml: wxml是微信自己给予xml技术开发，因此开发时只能使用微信提供的标签，HTML的标签是无法使用的。
wxss: wxss具有css的大部分特性，但不是所有的都支持，哪些支持哪些不支持，并没有明确的文档。
微信的架构是数据驱动的模式，它的UI和数据是分离的，所有的页面更新都需要通过对数据的更新来实现。
小程序分为两个部分webview和appService。其中webview主要用来展示UI，appService用来处理业务逻辑，数据及接口的调用。他们在两个进程中运行，通过系统jsBridge实现通讯，UI渲染、事件处理。

优势：一、无需下载通过扫一扫和搜索就可以打开
       二、良好的用户体验，打开快
       三、开发成本比app低
       四、安卓上可以添加到桌面，与原始app差不多
       五、为用户提供良好的安全保障。小程序的发布微信有一套严格的审查流程，不能通过的小程序是不能发布到线上的。
劣势：一、限制较多，页面大小不能超过1M,不能打开超过5个层级的页面
       二、样式单一，小程序的一些组件样式是成形的，样式不能修改。如幻灯片、导航。
       三、推广面窄，不能分享朋友圈，只能分享给朋友、附近小程序推广。其中附近小程序也受微信的限制。
       四、依托于微信，无法开发后台管理功能。
</code></pre><h3 id="8-微信小程序与h5的区别"><a href="#8-微信小程序与h5的区别" class="headerlink" title="8.微信小程序与h5的区别"></a>8.微信小程序与h5的区别</h3><pre><code>答：
    一、运行环境的不同
        传统的HTML运行环境是浏览器，包括webview,而微信小程序的运行环境并非完整的浏览器，是微信开发团队基于浏览器内核完全重构的解析器，针对小程序专门做了优化，配合自己开发的语言标准，提升了小程序的性能。
    二、开发成本的不同
        只在微信中运行，不用担心浏览器的兼容性，以及生产环境中出现的不可预料的奇妙bug
    三、获取系统级权限的不同
        系统级权限都可以和微信小程序无缝衔接
    四、应用在生产环境中的运行流畅度不同
        长久以来，HTML5应用面对复杂的业务逻辑或丰富的页面交互时，它的体验总是不尽人意，需要不断的优化项目来提升用户体验，但是由于微信小程序的运行环境独立，不用长期不断的进行优化来提升用户体验。

第二： 在部分事件的处理上，移动端多出来的事件是触屏事件，而缺少的是hover事件。 另外包括移动端弹出的手机键盘的处理，这样的问题在PC端都是遇不到的。 

第三： 在布局上，移动端开发一般是要做到布局自适应的，我使用的一直是rem布局，感觉很好。

第四： 在动画处理上，PC端由于要考虑IE的兼容性，所以通常使用JS做动画的通用性会更好一些，但是CSS3做了很大的牺牲， 而在手机端，如果要做一些动画、特效等，第一选择肯定是CSS3， 既简单、效率又高。

第五：  微信的一些接口组好能去实现一遍，熟悉一下肯定是有好处的，比如通过微信分享文章，title、description、icon等图标的配置，这些还是要会的。

第六： 百度地图的一些API接口，也得去实现一下，这些对于移动端来说，LBS是一个非常重要的特性，所以地图这块肯定是要了解的，在加上百度地图这块已经是一个比较成熟的平台了，所以学起来也比较容易。

第七： CSS3的动画一定要比较熟练，这在移动端用的还是比较多的。 

第八： 一般pc端用jquery，移动端用zepto，因为移动端的流量还是比较重要的， 所以引入的资源或者插件，能小则小，一个30k的资源和一个80k的资源，在移动端的差别还是挺大的。而未压缩的jquery是262kb， 压缩的jquey是83kb，可见两者的差别之大。

第九：最好能掌握一套完整的前端开发架构，比如模块化、打包、压缩、缓存、有条件的还可以做一下自动化测试等等，比较好用的有fis，另外，想要快速提升自己的前端开发技术，钻研前端架构这块是一个非常好的方向。

第十： 性能优化，包括首屏的打开速度、用户响应延迟、渲染性能、动画帧率等在手机上都需要特别注意。

 第十一： 比如在手机上的300ms的延迟，这在PC端是没有的，如果我们希望做成webapp，那么自然就不需要这300ms的延迟，所以可以使用hammer-time.js来移除这300ms的延迟。

&lt;section&gt;：定义文档中的节（section、区段）。比如章节、页眉、页脚或文档中的其他部分。

1.jsonp:原理是script标签的src属性，外联引入文件不受同源策略的限制，在页面中动态插入了script，scirpt标签的src属性就是后端api接口的地址，并且以get的方式将前端回调处理函数名称告诉后端，
后端在响应请求时会将回调返还，并且将数据以参数的形式传递回去
2.document.domin:两个域名必须属于同一基础域名，并且所有的协议端口完全一致，否则无法跨域；
3.iframe、hash:父页面向子页面传输数据：将要传递的数据添加到子页面的URL的hash值上，子页面通过location.hash并添加定时器实时的动态父页面传来的数据；
子页面向父页面传输数据：利用window.name的特性，及页面重新加载当前页面的name值不变，即使换了一个页面。需要三个页面配合使用。一个应用页面，一个数据页面，一个代理文件。代理文件一般是一个没有任何内容的html页面，
需要和应用页面在同一域名下。将数据页面的窗口缓存代理页面，代理页面通过window.name获取数据页面留下的数据，应用页面再访问和它同源的代理页面获取数据，就完成跨域。
4.CORS：服务器端设置的，不需要客户端进行操作。
5.服务器跨域，服务器中转代理。

7.webSocket
