HomeWeb Front-endJS TutorialjQuery validation plug-in Web front-end design pattern (asp.net)_jquery

Design goal: Build a universal web validation plug-in based on jQuery framework...

Design requirements: 1. Need beautiful css style and small icon decoration...
2. Based on jQuery framework.. .
3. Call the .net Web service to achieve asynchronous interaction with the database...

Solution: 1. First, let’s design three classes to display the visual appearance of the Web to the user. Perception. They are
.msg_warning{font-family:Arial,Helvetica,sans-serif,simsun; background:#e7f7ff url(register/MsgWarning.gif) no-repeat;border:solid 1px #6cf;color:#333 ;padding:0 0 0 36px !important;width:220px; margin-left:20px;}
.msg_error{font-family:Arial,Helvetica,sans-serif,simsun;background:#fff3ef url(register/MsgError .jpg) no-repeat;border:solid 1px #ff6610;color:#333;padding:0 0 0 36px !important;width:220px; margin-left:20px;}

.msg_ok{font- family:Arial,Helvetica,sans-serif,simsun;background:#e7ffe7 url(register/MsgOk.gif) no-repeat;border:solid 1px #95e895;color:#333;padding:0 0 0 36px !important;width :220px; margin-left:20px;}
They are different styles for verification errors, verification warnings and correct verification...
2. Place the image in the corresponding position, as shown in the style, including MsgWarning.gif, MsgError.jpg, and MsgOk.gif are three small pictures corresponding to .msg_warning; .msg_error; .msg_ok;

3. Start writing the script
(1), //Remove the null value

Copy code The code is as follows:

String.prototype.trim = function()
{
var x = this;
x = x.replace(/^s*(.*)/, "$1");
return x;
}

This function is used to remove empty positions (trim) in the text box...

(2). Write two arrays to store prompt statements and styles when triggering verification...
var ErrorWords = ['Correct! ', 'Cannot be empty! ', 'E-mail address length cannot exceed 50 characters! ', 'Please enter the correct email format! ',"The password must be greater than 6 and less than 16!","The key does not match!",'The company name cannot exceed 50 digits! ',"Neither the area code nor the number is empty!","The area code is 4 digits!","The number is 7-10 digits!","The QQ number is 5-12 digits!",'The address length is not More than 50 people! ','The name must be in Chinese within 10 characters! ','The mobile phone number is 11 digits! ','The zip code is 6 digits! ','The username is between 3-15 digits! ','The domain name format is wrong! ','This username has been registered! ','This email address has been registered! ']

var ErrorClass = ['msg_ok', 'msg_warning', 'msg_warning', 'msg_error', 'msg_warning', 'msg_error', 'msg_warning', 'msg_warning', 'msg_error','msg_error ','msg_error','msg_error','msg_error','msg_error','msg_error','msg_error','msg_error','msg_error','msg_error']

(3), start writing Various validation types, I wrote all I could think of...
Copy code The code is as follows:

;(function($){
//as long as
jQuery.fn.extend({
"checkEmail":function() //
{
$(this).blur(function(){

var email=$(this).val().toLowerCase();

4. Introduce scripts into the Web page
Copy code The code is as follows:






5. HTML source code of the Web page
Copy the code The code is as follows:


User login name verification:


Email verification:< ;input type="text" id="Emails"/>


Password verification: < ;br />

Change the password:


Company Name check:


Telephone: Area code:
-




Fax: Area code:
-



User QQ:


Company address:


User’s real name:


Mobile phone number verification:


Postcode verification:


Domain name verification:
Verification:




//This is the end


Design summary: There are still many imperfections, such as unexpected verification, There is also too much code redundancy. I hope I can improve it myself when using it...

mPDF

mPDF

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),
