When there are many fields in the verification form, you may want to put the HTML generation and verification logic in the controller. On the page, it may look like this:
<some-form fiedls="vm.someFields" ...></some-form>
Then, define each field and validation in the controller. angular-formly exists for this requirement.
In the controller, define each field in the array:
vm.rentalFields = [
{
key:'first_name',
type:'input',
templateOptions:{
type:'text',
label:'姓',
placeholder: '输入姓',
required: true
}
},
...
]
Use the hideExpression field to define hiding conditions:
{
key:'under18',
type:'checkbox',
templateOptions:{
label:'是否不满18岁'
},
hideExpression: '!model.email' //email验证失败之前不显示
}
Use the validators field to customize validation rules:
{
key:'license',
type:'input',
templateOptions:{
label:'身份证号',
placeholder:'输入身份证号'
},
hideExpression: '!model.province',
validators:{
driversLicense: function($viewValue, $modelValue, scope){
var value = $modelValue || $viewValue;
if(value){
return validateDriversLicence(value);
}
},
expressionProperties:{
'templateOptions.disabled':function($viewValue, $modelValue, scope){
if(scope.model.province == '山东省'){
return false;
}
return true;
}
}
}
First install: npm install angular-formly angular-formly-templates-bootstrap bootstrap api-check

JavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AMDifferent 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 WorldApr 12, 2025 am 12:06 AMJavaScript'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 LanguageApr 11, 2025 am 12:01 AMJavaScript 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 ProspectsApr 10, 2025 am 09:33 AMThe 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 MattersApr 09, 2025 am 12:07 AMJavaScript 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.
Is Python or JavaScript better?Apr 06, 2025 am 12:14 AMPython is more suitable for data science and machine learning, while JavaScript is more suitable for front-end and full-stack development. 1. Python is known for its concise syntax and rich library ecosystem, and is suitable for data analysis and web development. 2. JavaScript is the core of front-end development. Node.js supports server-side programming and is suitable for full-stack development.

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
