废话不多说了,下面给大家介绍使用正则表达式验证用户名、密码、手机号码、身份证的写法,需要的的朋友参考下吧
//用户名 + (BOOL) validateUserName:(NSString *)name { NSString *userNameRegex = @"^[A-Za-z0-9]{3,20}+$"; NSPredicate *userNamePredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",userNameRegex]; BOOL B = [userNamePredicate evaluateWithObject:name]; return B; } //密码 + (BOOL) validatePassword:(NSString *)passWord { NSString *passWordRegex = @"^[a-zA-Z0-9]{6,20}+$"; NSPredicate *passWordPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",passWordRegex]; return [passWordPredicate evaluateWithObject:passWord]; } //判断手机号码格式是否正确 + (BOOL)valiMobile:(NSString *)mobile { mobile = [mobile stringByReplacingOccurrencesOfString:@" " withString:@""]; if (mobile.length != 11) { return NO; }else{ /** * 移动号段正则表达式 */ NSString *CM_NUM = @"^((13[4-9])|(147)|(15[0-2,7-9])|(178)|(18[2-4,7-8]))\\d{8}|(1705)\\d{7}$"; /** * 联通号段正则表达式 */ NSString *CU_NUM = @"^((13[0-2])|(145)|(15[5-6])|(176)|(18[5,6]))\\d{8}|(1709)\\d{7}$"; /** * 电信号段正则表达式 */ NSString *CT_NUM = @"^((133)|(153)|(177)|(18[0,1,9]))\\d{8}$"; NSPredicate *pred1 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CM_NUM]; BOOL isMatch1 = [pred1 evaluateWithObject:mobile]; NSPredicate *pred2 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CU_NUM]; BOOL isMatch2 = [pred2 evaluateWithObject:mobile]; NSPredicate *pred3 = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CT_NUM]; BOOL isMatch3 = [pred3 evaluateWithObject:mobile]; if (isMatch1 || isMatch2 || isMatch3) { return YES; }else{ return NO; } } } /** * 验证身份证号码是否正确的方法 * * @param IDNumber 传进身份证号码字符串 * * @return 返回YES或NO表示该身份证号码是否符合国家标准 */ + (BOOL)isCorrect:(NSString *)IDNumber { NSMutableArray *IDArray = [NSMutableArray array]; // 遍历身份证字符串,存入数组中 if (IDNumber.length == 18) { for (int i = 0; i <p>相信看了本文案例你已经掌握了方法,更多精彩请关注php中文网其它相关文章!</p><p>推荐阅读:</p><p><a href="http://www.php.cn/js-tutorial-390621.html" target="_blank">在JS里编写简单的正则方式</a></p><p style="text-align: left;"><a href="http://www.php.cn/js-tutorial-390611.html" target="_blank">经常会用到的15个前端表单验证的正则</a><br></p>

Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.

Yes, the engine core of JavaScript is written in C. 1) The C language provides efficient performance and underlying control, which is suitable for the development of JavaScript engine. 2) Taking the V8 engine as an example, its core is written in C, combining the efficiency and object-oriented characteristics of C. 3) The working principle of the JavaScript engine includes parsing, compiling and execution, and the C language plays a key role in these processes.

JavaScript is at the heart of modern websites because it enhances the interactivity and dynamicity of web pages. 1) It allows to change content without refreshing the page, 2) manipulate web pages through DOMAPI, 3) support complex interactive effects such as animation and drag-and-drop, 4) optimize performance and best practices to improve user experience.

C and JavaScript achieve interoperability through WebAssembly. 1) C code is compiled into WebAssembly module and introduced into JavaScript environment to enhance computing power. 2) In game development, C handles physics engines and graphics rendering, and JavaScript is responsible for game logic and user interface.

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.
