Javascript method to close the page: 1. Close the window without any prompt through "window.close();"; 2. Close the page through "custom_close"; 3. Through "javascript:window.opener" =null;"Close the current page.
The operating environment of this article: windows7 system, javascript version 1.8.5, Dell G3 computer.
JS summary of several ways to close the current page (window)
1. JS code to close the window without any prompts
The code is as follows:
<a href="javascript:window.opener=null;window.open('','_self');window.close();">关闭</a>
2. Custom prompt close
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:
The code is as follows:
<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 can the close button pop up when the user clicks the close button in the browser's maximize/minimize close button? What about the confirmation dialog box? Like this:
The code is as follows:
<body onbeforeunload="return '真的要关闭此窗口吗?'">
In this case, the onbeforeunload function will be executed when the click is closed, and a dialog box will pop up asking "Do you really want to close this window?" , click Cancel to return false, do not close, click OK to return True and close the window
So how can I pop up the OK Cancel dialog box when clicking a certain button?? If you click Cancel, the following code will not be executed. Click OK to continue executing the following code?
Write in the click of the button:
The code is as follows:
Response.Write("<script language=\javascript\">" + "if(confirm(\"确定吗?\"))"+"{window.location.href='default.aspx';}"+"else{history.back();}"+"</script>");It 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 you click cancel, it will return false and execute history.back(); to return to Original page

Python vs. JavaScript: Use Cases and Applications ComparedApr 21, 2025 am 12:01 AMPython 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.
The Role of C/C in JavaScript Interpreters and CompilersApr 20, 2025 am 12:01 AMC 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 in Action: Real-World Examples and ProjectsApr 19, 2025 am 12:13 AMJavaScript'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.
JavaScript and the Web: Core Functionality and Use CasesApr 18, 2025 am 12:19 AMThe 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 the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AMUnderstanding 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 vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AMPython 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 vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AMPython 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.
From C/C to JavaScript: How It All WorksApr 14, 2025 am 12:05 AMThe shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

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),
