JS summary of several ways to close the current page (window), friends in need can refer to it
1. JS code to close the window without any prompt
The code is as follows:
<a href="javascript:window.opener=null;window.open('','_self');window.close();">关闭</a>
2. Custom prompt is closed
The code is as follows:
<script language="javascript"> // 这个脚本是 ie6和ie7 通用的脚本 function custom_close(){ if (confirm("您确定要关闭本页吗?")){ window.opener=null; window.open('','_self'); window.close(); } else{} } </script> <input id="btnClose" type="button" value="关闭本页" onClick="custom_close()" />
3. Close the current page:
<a href="javascript:window.opener=null;window.close();">关闭</a>如果是按钮则: Response.Write("<script language=\"javascript\">window.opener=null;window.close();</script>");
In this way, when you click Close, the dialog box that the current window is trying to close will not pop up.
So how do you do that? When the user clicks the close button in the maximize or minimize close button of the browser, a closing confirmation dialog box will pop up? Like this:
The code is as follows:
<body onbeforeunload="return '真的要关闭此窗口吗?'">
In this case, click close When the onbeforeunload function is executed, a dialog box pops up asking whether you really want to close this window. Click Cancel to return false, do not close, click OK to return True to close the window
So how can you click a button? What about the confirmation and cancellation dialog box that pops up? If you click Cancel, the following code will not be executed. If you click OK, it will continue to execute the following code?
Write in the button click:
The code is as follows:
Response.Write("<script language=\javascript\">" + "if(confirm(\"确定吗?\"))"+"{window.location.href='default. asp x';}"+"else{history.back();}"+"</script>");
means: first use the confirm function to pop up a dialog box with confirmation to cancel. If you click OK, it will return true and execute the window.location.href='default.aspx' code. If Click Cancel to return to false, and execute history.back(); return to the original page

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.

JavaScript does not require installation because it is already built into modern browsers. You just need a text editor and a browser to get started. 1) In the browser environment, run it by embedding the HTML file through tags. 2) In the Node.js environment, after downloading and installing Node.js, run the JavaScript file through the command line.

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),
