PHP+jQuery 注册模块开发,phpjquery模块开发
<span>/*</span><span> ******* 环境: Apache2.2.8 + PHP5.2.6 + MySQL5.0.51b + jQuery-1.8.3.min.js *******<br />******* 其他组件:Zend_mail( Zend_framework 1.11.11 )<br />******* Date:2014-09-25<br />******* Author:小dee<br />******* Blog:http://www.cnblogs.com/dee0912/<br /></span><span>*/</span>
写了一个简单的PHP+jQuery注册模块,需要填写的栏目包括用户名、邮箱、密码、重复密码和验证码,其中每个栏目需要具备的功能和要求如下图:
在做这个模块的时候,很大程度上借鉴了网易注册( http://reg.163.com/reg/reg.jsp?product=urs )的功能和样式。但网易对于每个栏目的判断的做法是:在输入文字时,并不给出任何实时的检测结果,而在这个栏目失去焦点时,才把检测的结果展示出来,这种做法我认为会使用户在输入时视觉上比较统一,看到的是关于该栏目要求的提示,不会出现其他信息的打扰,但同时也不会得到正在输入的字符的检测提示。所以在做这个功能的时候,我把我自认为需要实时提示的一些信息做了相应的加强,比如用户名长度超过限制和密码的长度以及强弱,并且给邮箱的大写锁定做了简单的判断。
注:表单的提交按钮type为button而不是submit,因此所有栏目的回车( keydown )都统一设置为将焦点移至下一个栏目,除了最后一个栏目验证码,在验证码栏目使用回车( keydown )会触发提交事件。
功能分析
用户名栏目:
流程
①页面加载完即获得焦点,获得焦点时出现初始说明文字;
②鼠标点击用户名输入框,出现初始说明文字;
③输入字符,即时提示是否符合长度要求;
④失去焦点时首先判断是否为空,为空时提示不能为空;非空且长度满足要求时,开始检测用户名是否被注册;
⑤用户名已被注册,给出提示,如果没有注册,则提示可以注册;
⑥再次获得焦点时,不论输入框中是否有输入,或是否输入符合规定,都出现初始说明文字
⑦回车时将焦点移至邮箱栏目
如图:
细节
可以使用任意字符,并且字数限制为:中文长度不超过7个汉字,英文、数字或符号长度不超过14个字母、数字或符号(类似豆瓣注册https://www.douban.com/accounts/register),即不超过14个字符
关于占位符(字符长度),一个汉字的占位符是2,一个英文(数字)的占位符是1,可以用php语句来计算字符的长度
<span>1</span> <?<span>php </span><span>2</span> <span>//</span><span>php.ini开启了php_mbstring.dll扩展</span> <span>3</span> <span>$str</span>="博客园小dee"<span>; </span><span>4</span> <span>5</span> <span>echo</span> (<span>strlen</span>(<span>$str</span>)+mb_strlen(<span>$str</span>,'utf-8'))/2;
输出:11
而strlen($str) 输出的是15:4*3+3,汉字在utf-8编码下占3个字节,英文占1个,
mb_strlen($str,'utf-8') 输出的是7:一个汉字的长度是1,
如果用jquery的length来输出这个字符串,alert($("#uname").val().length),则会得到长度7,
这点要注意。
同时用户名两端不能含有空格,在检测以及注册时,程序会自动过滤用户名两端的空格。

提示文字( Chrome下 )
①初始获得焦点、再次获得焦点或点击时
②输入时实时检测长度
③删除至空且未失去焦点时,使用蓝色图标提示不能为空——用户在输入时看起来不突兀
④失去焦点且不为空,检测是否被注册( 非常短暂,一闪而过 )
⑤失去焦点时为空、可以注册、已被注册时
用户名分析至此完毕。
邮箱栏目:
流程
①当栏目获得焦点或者点击时不论栏目为空、填写正确或者填写错误时都出现说明文字;
②用户输入时出现下拉菜单显示多种邮件后缀供用户选择;
③失去焦点时首先判断邮箱格式是否正确,如果正确则检测邮箱是否被注册 ;
④在使用回车选择下拉菜单时,将自动填充邮箱栏目;没有出现下拉菜单时,将焦点移至密码栏目

邮箱功能至此结束。
密码栏目:
要求
①6-16个个字符,区分大小写(参考豆瓣和网易)
②密码不能为同一字符
③实时提示是否符合要求以及判断并显示密码强度,:
1.输入时如果为空(删除时)则用蓝色符号提示不能为空,超过长度时用红色符号
2.密码满足长度但是为相同字符的组合时:密码太简单,请尝试数字、字母和下划线的组合
3.密码强度判断有多种规则,有直接依据长度和组合规则作出判断,也有给每种长度和组合设置分数,通过验证实际密码的情况计算出最后分数来判断强弱。在这个模块中采用比较简单的一种形式,也是网易注册采用的方法:
密码满足长度且全部为不同字母、全部为不同数字或全部为不同符号时为弱:弱:试试字母、数字、符号混搭
密码满足长度且为数字、字母和符号任意两种组合时为中
密码满足长度且为数字、字母和符号三种组合时为强
④输入时大写提示

大写锁定的思路是:判断输入的字符的最新一位是否是大写字母,如果是大写字母,则提示大写锁定键打开。这种方法并不十分准确,网上有一些插件能判断大写锁定,在这里只是简单地做了一下判断。

JWT adalah standard terbuka berdasarkan JSON, yang digunakan untuk menghantar maklumat secara selamat antara pihak, terutamanya untuk pengesahan identiti dan pertukaran maklumat. 1. JWT terdiri daripada tiga bahagian: header, muatan dan tandatangan. 2. Prinsip kerja JWT termasuk tiga langkah: menjana JWT, mengesahkan JWT dan muatan parsing. 3. Apabila menggunakan JWT untuk pengesahan di PHP, JWT boleh dijana dan disahkan, dan peranan pengguna dan maklumat kebenaran boleh dimasukkan dalam penggunaan lanjutan. 4. Kesilapan umum termasuk kegagalan pengesahan tandatangan, tamat tempoh, dan muatan besar. Kemahiran penyahpepijatan termasuk menggunakan alat debugging dan pembalakan. 5. Pengoptimuman prestasi dan amalan terbaik termasuk menggunakan algoritma tandatangan yang sesuai, menetapkan tempoh kesahihan dengan munasabah,

Mengikat statik (statik: :) Melaksanakan pengikatan statik lewat (LSB) dalam PHP, yang membolehkan kelas panggilan dirujuk dalam konteks statik dan bukannya menentukan kelas. 1) Proses parsing dilakukan pada masa runtime, 2) Cari kelas panggilan dalam hubungan warisan, 3) ia boleh membawa overhead prestasi.

Apakah kaedah sihir PHP? Kaedah sihir PHP termasuk: 1. \ _ \ _ Membina, digunakan untuk memulakan objek; 2. \ _ \ _ Destruct, digunakan untuk membersihkan sumber; 3. \ _ \ _ Call, mengendalikan panggilan kaedah yang tidak wujud; 4. \ _ \ _ Mendapatkan, melaksanakan akses atribut dinamik; 5. \ _ \ _ Set, melaksanakan tetapan atribut dinamik. Kaedah ini secara automatik dipanggil dalam situasi tertentu, meningkatkan fleksibiliti dan kecekapan kod.
