本文实例讲述了jquery密码强度校验的验证代码,分享给大家供大家参考。具体如下:
预想的效果截图如下:

关键代码:

<script>
 
//下面的正则表达式建议各位收藏哦,项目上有可能会用得着
$(function(){  
  $('#pass').blur(function(e) {
    // alert('---------');
     //密码为八位及以上并且字母数字特殊字符三项都包括
     var strongRegex = new RegExp("^(&#63;=.{8,})(&#63;=.*[A-Z])(&#63;=.*[a-z])(&#63;=.*[0-9])(&#63;=.*\\W).*$", "g");
   
   //密码为七位及以上并且字母、数字、特殊字符三项中有两项,强度是中等 
     var mediumRegex = new RegExp("^(&#63;=.{7,})(((&#63;=.*[A-Z])(&#63;=.*[a-z]))|((&#63;=.*[A-Z])(&#63;=.*[0-9]))|((&#63;=.*[a-z])(&#63;=.*[0-9]))).*$", "g");
     var enoughRegex = new RegExp("(&#63;=.{6,}).*", "g");
     if (false == enoughRegex.test($(this).val())) {
         $('#passstrength').html('More Characters');
     } else if (strongRegex.test($(this).val())) {
         $('#passstrength').className = 'ok';
         $('#passstrength').html('Strong!');
     } else if (mediumRegex.test($(this).val())) {
         $('#passstrength').className = 'alert';
         $('#passstrength').html('Medium!');
     } else {
         $('#passstrength').className = 'error';
         $('#passstrength').html('Weak!');
     }
     return true;
  });
}); 
</script> 
         
<input type="password" name="pass" id="pass" /> 
<span id="passstrength"></span>

以上就是jquery判断密码强度校验代码,大家可以应用到自己的项目中,希望大家喜欢。

From C/C   to JavaScript: How It All WorksFrom C/C to JavaScript: How It All WorksApr 14, 2025 am 12:05 AM

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

JavaScript Engines: Comparing ImplementationsJavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AM

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

Beyond the Browser: JavaScript in the Real WorldBeyond the Browser: JavaScript in the Real WorldApr 12, 2025 am 12:06 AM

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.

JavaScript: Exploring the Versatility of a Web LanguageJavaScript: Exploring the Versatility of a Web LanguageApr 11, 2025 am 12:01 AM

JavaScript is the core language of modern web development and is widely used for its diversity and flexibility. 1) Front-end development: build dynamic web pages and single-page applications through DOM operations and modern frameworks (such as React, Vue.js, Angular). 2) Server-side development: Node.js uses a non-blocking I/O model to handle high concurrency and real-time applications. 3) Mobile and desktop application development: cross-platform development is realized through ReactNative and Electron to improve development efficiency.

The Evolution of JavaScript: Current Trends and Future ProspectsThe Evolution of JavaScript: Current Trends and Future ProspectsApr 10, 2025 am 09:33 AM

The latest trends in JavaScript include the rise of TypeScript, the popularity of modern frameworks and libraries, and the application of WebAssembly. Future prospects cover more powerful type systems, the development of server-side JavaScript, the expansion of artificial intelligence and machine learning, and the potential of IoT and edge computing.

Demystifying JavaScript: What It Does and Why It MattersDemystifying JavaScript: What It Does and Why It MattersApr 09, 2025 am 12:07 AM

JavaScript is the cornerstone of modern web development, and its main functions include event-driven programming, dynamic content generation and asynchronous programming. 1) Event-driven programming allows web pages to change dynamically according to user operations. 2) Dynamic content generation allows page content to be adjusted according to conditions. 3) Asynchronous programming ensures that the user interface is not blocked. JavaScript is widely used in web interaction, single-page application and server-side development, greatly improving the flexibility of user experience and cross-platform development.
