Share 2 jQuery plug-ins-jquery.fileupload and artdialog_jquery
These are essential things in our project, so today I recommend two jquery plug-ins called artdialog, which is an iframe, and one called jquery file upload. I see that there are very few tutorials on how to use this plug-in jquery file upload on the Internet. Today I will briefly introduce and write down some methods of using it!
A simple example using code
Minimization method
data-url is a php method that executes the uploaded file after uploading
<script><br /> $(function () {<br /> $('#fileupload').fileupload({<br /> dataType: 'json', //josn transmission<br /> done: function (e, data) { //Execute after uploading<br /> $.each(data.result.files, function (index, file) {<br /> $('<p/>').text(file.name).appendTo(document.body);<br /> });<br /> }<br /> });<br /> });<br /> </script>
Expand it a little
<script><br /> $(function(){<br /> //The complete API is here<a href="https://github.com/blueimp/jQuery-File-Upload/wiki/API">https://github.com/blueimp/jQuery-File-Upload/wiki/API I will simply introduce some commonly used instructions<br /> $("#fileupload").fileupload('option',{ //Set upload event<br /> url: 'http://localhost/php/index.php' //Specify php upload method<br /> disableImageResize: /Android(?!.*Chrome)|Opera/<br /> .test(window.navigator.userAgent), . to acceptFileTypes: /(.|/)(rar|zip|jp?g|png|bmp)$/i, //Set the upload type<br /> });<br /> $.ajax({<br /> url: $('#fileupload').fileupload('option', 'url'), //According to the setting option ajax transmission<br /> dataType: 'json',<br /> context: $('#fileupload')[0]<br /> }).done(function (result) {<br /> $(this).fileupload('option','done'<br /> ).call(this, $.Event('done'), {result: result}); //Things to do after the upload is completed<br /> });<br /> $('#fileupload').bind('fileuploaddone',function(e,data){ //Bind the event that the upload is completed <br /> $.each(data.result.files, function (index,file){<br /> for(var i in file){<br /> alert(i ':' file[i])<br /> }<br /> });<br /> //There are too many bound events. If you translate it directly, you will understand what it means<br /> $('#fileupload')<br /> .bind('fileuploadadd', function (e, data) {/* ... */})<br /> .bind('fileuploadsubmit', function (e, data) {/* ... */})<br /> .bind('fileuploadsend', function (e, data) {/* ... */})<br /> .bind('fileuploaddone', function (e, data) {/* ... */})<br /> .bind('fileuploadfail', function (e, data) {/* ... */})<br /> .bind('fileuploadalways', function (e, data) {/* ... */})<br /> .bind('fileuploadprogress', function (e, data) {/* ... */})<br /> .bind('fileuploadprogressall', function (e, data) {/* ... */})<br /> .bind('fileuploadstart', function (e) {/* ... */})<br /> .bind('fileuploadstop', function (e) {/* ... */})<br /> .bind('fileuploadchange', function (e, data) {/* ... */})<br /> .bind('fileuploadpaste', function (e, data) {/* ... */})<br /> .bind('fileuploaddrop', function (e, data) {/* ... */})<br /> .bind('fileuploaddragover', function (e) {/* ... */})<br /> .bind('fileuploadchunksend', function (e, data) {/* ... */})<br /> .bind('fileuploadchunkdone', function (e, data) {/* ... */})<br /> .bind('fileuploadchunkfail', function (e, data) {/* ... */})<br /> .bind('fileuploadchunkalways', function (e, data) {/* ... */});<br /> });<br /> });<br /></script>
Since this plug-in is very powerful and has too many methods and APIs, you can take a look at the API on the official website first. Of course, you can also ask me if you don’t understand!
The second one is actually very simple ArtDialog. It was developed by Chinese people. All the APIs are in Chinese, so students can understand it at a glance. Here I will talk about one thing, that is, how to transmit data when the iframe is closed?
<script><br /> function nihao(){<br /> art.dialog.open( //Open an iframe remote file<br /> "<a href="http://localhost/dialog/index2.html">http://localhost/dialog/index2.html",<br /> {<br /> Title: "Testing Page",<br /> width: 320, <br /> height: 400,<br /> Close : function(){<br /> //Executed when the iframe is closed <br /> alert("my god is closed")<br /> }<br /> }<br /> );<br /> }<br /> </script>
Submit
I want to transfer the index2.html data back. Of course, my index2 will already transfer the data back to the parent iframe when I click on X. How can I do this? The code below is
<script><br /> var origin = artDialog.open.origin;<br /> var v = origin.document.getElementById('nihao');<br /> v.value = document.getElementById('chushu').value;<br /> </script>
Of course the data is not transmitted by clicking the That’s it!

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),
