jQuery implements the method of selecting text with the mouse to post on Sina Weibo_jquery
The example in this article describes how jQuery implements mouse-selected text to post on Sina Weibo. Share it with everyone for your reference, the details are as follows:
I recently noticed that Sina Blog has a small function, that is, when the mouse selects a piece of text, a small picture will appear. Click on this picture to send the selected content to Sina Weibo. On a whim, I wrote a demo last night to play with. Take a look, the code is super simple and not optimized. Friends who are interested can improve it themselves.
The principle is very simple, first get the mouse to select the text, then call the page provided in Sina Blog, and pass the text as a parameter.
The code is as follows:
<html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <style type="text/css"> .tooltip { width:120px; height:23px; line-height:23px; background-color:#CCCCCC; } .tooltip a { color: #333333; display: block; font-size: 12px; font-weight: bold; text-indent: 10px; } </style> <script src="jquery.min.js"></script> <script type="text/javascript"> $(function () { $("#blogContent").mouseup(function (e) { var x = 10; var y = 10; var r = ""; if (document.selection) { r = document.selection.createRange().text; } else if (window.getSelection()) { r = window.getSelection(); } if (r!= "") { var bowen = "发送到新浪微博"; var tooltip = "<div id='tooltip' class='tooltip'><a onclick=ask('"+r+"')>" + bowen + "</a></div>"; $("body").append(tooltip); $("#tooltip").css({ "top": (e.pageY + y) + "px", "left": (e.pageX + x) + "px", "position": "absolute" }).show("fast"); } }).mousedown(function () { $("#tooltip").remove(); }); }) function ask(r) { if (r != "") { window.open('http://v.t.sina.com.cn/share/share.php?searchPic=false&title='+r+'&url=http://www.nowwamagic.net&sourceUrl=http%3A%2F%2Fblog.sina.com.cn&content=utf-8&appkey=1617465124', '_blank', 'height=515, width=598, toolbar=no, menubar=no, scrollbars=auto, resizable=yes, location=no, status=yes'); } } </script> </head> <body> <div id="blogContent"> words words words words words words words words words。 </div> </body> </html>
It’s that simple, you can try it yourself. Of course, there are other operations to get the selected text. This is just a trick to call Sina's page. If you are interested, you can create your own application and implement it yourself.

I hope this article will be helpful to everyone in jQuery programming.

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.

JavaScript is the core language of modern web development and is widely used for its diversity and flexibility. 1) Front-end development: build dynamic web pages and single-page applications through DOM operations and modern frameworks (such as React, Vue.js, Angular). 2) Server-side development: Node.js uses a non-blocking I/O model to handle high concurrency and real-time applications. 3) Mobile and desktop application development: cross-platform development is realized through ReactNative and Electron to improve development efficiency.

The latest trends in JavaScript include the rise of TypeScript, the popularity of modern frameworks and libraries, and the application of WebAssembly. Future prospects cover more powerful type systems, the development of server-side JavaScript, the expansion of artificial intelligence and machine learning, and the potential of IoT and edge computing.

JavaScript is the cornerstone of modern web development, and its main functions include event-driven programming, dynamic content generation and asynchronous programming. 1) Event-driven programming allows web pages to change dynamically according to user operations. 2) Dynamic content generation allows page content to be adjusted according to conditions. 3) Asynchronous programming ensures that the user interface is not blocked. JavaScript is widely used in web interaction, single-page application and server-side development, greatly improving the flexibility of user experience and cross-platform development.

Python is more suitable for data science and machine learning, while JavaScript is more suitable for front-end and full-stack development. 1. Python is known for its concise syntax and rich library ecosystem, and is suitable for data analysis and web development. 2. JavaScript is the core of front-end development. Node.js supports server-side programming and is suitable for full-stack development.
