HomeWeb Front-endJS TutorialValidator validation control usage code_form effects

The following is the js code (it feels very inelegant when binding objects, I hope an expert can give me some advice!)

Copy code The code is as follows:

function validator(obj,option){//Validation object
var self = this;
if(!(self instanceof validator))
return new validator(obj,option);
self.source={'mobile':'^(13|14|15|18)[0-9]{9}$','postcode':'^\d {6}$','integer':'^-?\d*$','email':'^\w ((-\w )|(\.\w ))*\@[A-Za- z0-9] ((\.|-)[A-Za-z0-9] )*\.[A-Za-z0-9] $','url':'^http[s]?:\/ \/([\w-] \.) [\w-] ([\w-./?%&=]*)?$'};
for(var i in self.source){
if(i==option.type)
self.type=self.source[i];
}
self.tag=2;
self.input=obj;
self .options=option;
self.tip=document.getElementById(self.options.tips);
self.text=self.tip.innerHTML;
self.init(obj);
}
validator.prototype.init=function(o){
var self=this;
addEvent(o,'focus',function(){
self.focus();
} );
addEvent(o,'blur',function(){
self.valid();
});
}
validator.prototype.valid=function(){
var self=this;
var reg=self.options.reg||self.type;
if(new RegExp(reg).test(self.input.value.replace(/s/ig, ''))){
self.tip.className='validator_oncorrect';
self.tip.innerHTML='Input is correct';
self.tag=1;
}else{
self.tip.className='validator_onerror';
self.tip.innerHTML='Sorry, the content you entered does not comply with the rules! ';
self.tag=0;
}
}
validator.prototype.focus=function(){
this.tip.className='validator_onfocus';
this. tip.innerHTML=this.text;
}
function addEvent(el,type,fn){ //Bind event
if(el.attachEvent) {
el['e' type fn ] = fn; //Copy the element reference under IE so that this points to the el object instead of window
el[type fn] = function(){el['e' type fn](window.event);}
el.attachEvent('on' type, el[type fn]);
}else
el.addEventListener(type, fn, false);
}
//Page call method
var inputs=document.getElementsByTagName('input');//The writing here feels weird and not elegant enough, and I haven't found a way to optimize it yet
var arr=[];
arr[0]= validator(inputs[0],{type:'postcode',tips:'m1'});
arr[1]=validator(inputs[1],{type:'url',tips:'m2'} );
arr[2]=validator(inputs[2],{type:'email',tips:'m3'});
arr[3]=validator(inputs[3],{type: 'mobile',tips:'m4'});
arr[4]=validator(inputs[4],{type:'integer',tips:'m5',reg:'^-?\d*$ '});
function submitForm(){//Submit form filtering
var l=arr.length;
for(var i in arr){
if(arr[i].tag= =1)
l--;
else if(arr[i].tag==2){
arr[i].valid();
}
}
if(l!=0)return false;
}

The following is the page demo. It may be missing a small icon. I don’t know how to send executable code.
Copy code The code is as follows:

JavaScript's Role: Making the Web Interactive and DynamicJavaScript's Role: Making the Web Interactive and DynamicApr 24, 2025 am 12:12 AM

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: The Connection ExplainedC and JavaScript: The Connection ExplainedApr 23, 2025 am 12:07 AM

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.

From Websites to Apps: The Diverse Applications of JavaScriptFrom Websites to Apps: The Diverse Applications of JavaScriptApr 22, 2025 am 12:02 AM

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 vs. JavaScript: Use Cases and Applications ComparedPython vs. JavaScript: Use Cases and Applications ComparedApr 21, 2025 am 12:01 AM

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.

The Role of C/C   in JavaScript Interpreters and CompilersThe Role of C/C in JavaScript Interpreters and CompilersApr 20, 2025 am 12:01 AM

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 in Action: Real-World Examples and ProjectsJavaScript in Action: Real-World Examples and ProjectsApr 19, 2025 am 12:13 AM

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.

JavaScript and the Web: Core Functionality and Use CasesJavaScript and the Web: Core Functionality and Use CasesApr 18, 2025 am 12:19 AM

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding the JavaScript Engine: Implementation DetailsUnderstanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AM

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.
