Page turning without refreshing through pjax (compatible with new version of jquery)_jquery
pushState is an API that can operate history. For the introduction and use of the API, please see here: http://www.welefen.com/use-ajax-and-pushstate.html
Currently, http://github.com/, http://plus.google.com, http://www.welefen.com and other websites have been used.
pjax is an encapsulation of ajax pushState, allowing you to use pushState technology very conveniently.
Supports both caching and local storage. The local data can be read directly the next time you visit, without the need for another visit.
And the display method supports animation technology. You can use the system’s own animation method or customize the animation display method.
I won’t introduce much about pjax here. It is simple and easy to use, and you can easily achieve partial refresh and say goodbye to the flickering caused by links.
I have seen pjax before and implemented the demo, and also wrote a note. However, jquery 1.9 deleted the live() method, and the new version of pjax also changed to use the on() method. It has been used in recent projects, so After understanding the new usage method, I also make a new note here.
Environment:
jquery 1.10.2 Download
jquery.pjax.js Download
Usage:
Monitor all links with class pjaxlink, and use pjax to update the container content with id ToInsert in the link page to the container with id content in this page. If it takes more than 5 seconds to obtain the content, it will jump directly to:
$(document).pjax('a.pjaxlink' , '#Content', {fragment:'#ToInsert', timeout:5000});
Usage example:
The original page is turned through a jump. I use pjax to monitor the page turning link without changing the page content, and only update the list (make sure the list container is the parent node of the paging container) content.
if ($.support.pjax) {
//Traverse all paging containers
$('.pagercontainer').each(function(){
//Get the list container
$listcontainer=$(this).parent();
/ /Get the ID of the list container
var listcontainerid=$listcontainer.attr('id');
//Use pjax to monitor all paging links and define pjax to update
$(document).pjax(' #' listcontainerid ' .pagercontainer a', '#' listcontainerid, {fragment:'#' listcontainerid, timeout:5000});
});
$(document).on('pjax:send', function() {
// When pjax sends a request, display the loading animation layer 'pjax:complete', function() {
//After the pjax processing is completed, hide the loading animation layer
//Because the speed is too fast, the loading layer will flicker and affect the experience, so add 500 here Millisecond delay
setTimeout(function(){$('#loading').hide()},500);
});

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 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.

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'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.

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 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.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

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),
