The principle is to use a 1px div, see the code for the specific implementation.
Usage:
$('.test' ).rounder();
This will generate a rounded box based on the default settings, as shown below:
The rounded corners will be a little jagged:(
If that’s all, it’s definitely not enough. What if we want to add a style of our own? How to use:
$('.test').rounder({borderColor:'red',backgroundColor:'# EEE',color:'blue'});
The effect is as shown below:
Next I will talk about the implementation process. First, attach the jQuery code as follows:
(function($){
$.fn.rounder=function(options){
var setting=$.extend({backgroundColor:'#FFF',borderColor:' #AAA',color:'#000'},options||{});
this.each(function(){
var source=$(this);
var container=source.parents (".mapping_rounder");
if(container.size()container=$('');
source.before(container);
//Add 1pxDIV
container.append('
container.find('.rounder_content').append(source);
//Maintain the original shape, such as height, width, etc.
container.width(source.width());
source.width(source.width()-12);
container.height(source.height());
source.height(source. height()-8);
source.css('lineHeight',source.height() 'px');
container.css('marginTop',source.css('marginTop'));
source.css('marginTop',0);
container.css('marginBottom',source.css('marginBottom'));
source.css('marginBottom',0);
container.css('marginLeft',source.css('marginLeft'));
source.css('marginLeft',0);
container.css('marginRight',source.css('marginRight '));
source.css('marginRight',0);
}
//Add a style to 1pxDIV to produce a rounded border effect
container.find('.rounder_px3') .css('backgroundColor',setting.borderColor);
container.find('.rounder_px2').css({borderColor:setting.borderColor,backgroundColor:setting.backgroundColor});
container.find(' .rounder_px1').css({borderColor:setting.borderColor,backgroundColor:setting.backgroundColor});
container.find('.rounder_px0').css({borderColor:setting.borderColor,backgroundColor:setting.backgroundColor} );
container.find('.rounder_content').css({borderColor:setting.borderColor,backgroundColor:setting.backgroundColor});
//Remove the original style
source.css(' borderStyle','none');
source.css('backgroundColor',setting.backgroundColor);
source.css('color',setting.color);
});
}
})(jQuery);
CSS file code:
.rounder_content{padding:0 5px;border-left:1px solid;border-right:1px solid;}
.rounder_px0{margin:0;height:2px;border-left :2px solid;border-right:2px solid;overflow:hidden;}
.rounder_px1{margin:0 1px;height:1px;border-left:2px solid;border-right:2px solid;overflow:hidden;}
.rounder_px2{margin:0 2px;height:1px;border-left:3px solid;border-right:3px solid;overflow: hidden;}
.rounder_px3{margin:0 3px;height:1px;background :#AAA;overflow:hidden;}
원래 이 CSS 파일의 스타일은 jQuery를 사용하여 추가할 수 있지만 그렇게 하려면 더 많은 코드가 필요하고 여기서는 게으릅니다. -||| 스타일에 Overflow:hidden;을 추가하는 목적은 IE6과 호환되도록 하는 것입니다. 왜냐하면 IE6에서는 DIV의 기본 최소 높이가 13px인 것으로 보입니다.
이 기능은 매우 간단하지만 다음과 같이 일반적인 애플리케이션에 적용할 수 있습니다.
즉, 텍스트 상자의 모서리가 둥글게 되었습니다. 포커스를 받으면 스타일을 표시하고 포커스를 잃으면 다른 스타일을 표시합니다.
물론 jQuery 자체의 강력한 기능과 결합하면 다양한 요구 사항을 충족할 수 있습니다.
장점:
작은 크기, 압축 후 두 파일의 크기가 2.23kb에 불과합니다.
사용하기 쉬움
단점:
테두리의 곡률과 선 굵기 조정 불가 (필요시 jquery.corner 플러그인 참고)
높이와 글자 크기가 잘 맞지 않아 글자가 반쯤 가려지는 경우도 있습니다
IE6, FF에서 테스트, 오페라, 사파리, 크롬

JavaScript core data types are consistent in browsers and Node.js, but are handled differently from the extra types. 1) The global object is window in the browser and global in Node.js. 2) Node.js' unique Buffer object, used to process binary data. 3) There are also differences in performance and time processing, and the code needs to be adjusted according to the environment.

The main difference between Python and JavaScript is the type system and application scenarios. 1. Python uses dynamic types, suitable for scientific computing and data analysis. 2. JavaScript adopts weak types and is widely used in front-end and full-stack development. The two have their own advantages in asynchronous programming and performance optimization, and should be decided according to project requirements when choosing.

Whether to choose Python or JavaScript depends on the project type: 1) Choose Python for data science and automation tasks; 2) Choose JavaScript for front-end and full-stack development. Python is favored for its powerful library in data processing and automation, while JavaScript is indispensable for its advantages in web interaction and full-stack development.

Python and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.

JavaScript can be used for front-end and back-end development. The front-end enhances the user experience through DOM operations, and the back-end handles server tasks through Node.js. 1. Front-end example: Change the content of the web page text. 2. Backend example: Create a Node.js server.

Choosing Python or JavaScript should be based on career development, learning curve and ecosystem: 1) Career development: Python is suitable for data science and back-end development, while JavaScript is suitable for front-end and full-stack development. 2) Learning curve: Python syntax is concise and suitable for beginners; JavaScript syntax is flexible. 3) Ecosystem: Python has rich scientific computing libraries, and JavaScript has a powerful front-end framework.

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),
