JavaScript method to obtain client IP (new method)_javascript skills
For a long time, I have used http://fw.qq.com/ipaddress to get the IP of the client user. This method is simple, fast and practical.
The way we call it is:
<script type="text/javascript" src="http://fw.qq.com/ipaddress"></script>
It can return user IP and location, metaphor:
var IPData = new Array("220.181.108.85","","北京市",""); We can now use IPData[0] as the user IP.
But I don’t know what happened to Tencent recently. This location has failed, prompting "HTTP 500 Internal Server Failure".
Another way to get the client IP using js
Recently, I learned another way to get the client IP. This service is provided by an overseas website.
The application method is as follows:
<script language="JavaScript"> VIH_BackColor = "palegreen"; VIH_ForeColor = "navy"; VIH_FontPix = "16"; VIH_DisplayFormat = "You are visiting from: IP Address: %%IP%% Host: %%HOST%%"; VIH_DisplayOnPage = "yes"; </script> <script language="JavaScript" src="http://www.hashemian.com/js/visitorIP.js.php"></script>
The following is your IP:
You are visiting from: IP Address: 117.87.4.102 Host: 102.4.87.117.broad.xz.js.dynamic.163data.com.cn
If you don’t want to display it on the web page, but just want to obtain the IP for other purposes, you need to change VIH_DisplayOnPage = "yes" to VIH_DisplayOnPage = "no". The IP variable is VIH_HostIP.
The calling method is as follows:
<script language="JavaScript">
VIH_DisplayOnPage = "no";
</script>
<script language="JavaScript" src="http://scripts.hashemian.com/js/visitorIPHOST.js.php"></script>
<script language="JavaScript">
alert("你的IP是：" + VIH_HostIP);
</script> Let me introduce JavaScript to obtain the client IP and MAC address
If you cannot obtain it, you need to set up the IE browser. The specific settings are as follows:
Please set the third item of IE browser-Tools-Security-Custom Level-ActiveX to enable 'Initialize and script run ActiveX controls not marked as safe', click OK, refresh and log in again!
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>JavaScript获取客户端IP</title>
<script type="text/javascript" language="javascript">
<!--
function GetLocalIPAddress()
{
var obj = null;
var rslt = "";
try
{
obj = new ActiveXObject("rcbdyctl.Setting");
rslt = obj.GetIPAddress;
obj = null;
}
catch(e)
{
//异常发生
}
return rslt;
}
function getMac(){
var locator = new ActiveXObject ("WbemScripting.SWbemLocator");
var service = locator.ConnectServer(".");
var properties = service.ExecQuery("Select * from Win32_NetworkAdapterConfiguration Where IPEnabled =True");
var e = new Enumerator (properties);
{
var p = e.item();
var mac = p.MACAddress;
return mac
}
}
//-->
function init () {
var ip = GetLocalIPAddress();
var mac = getMac();
fm.clientIP.value = ip;
fm.clientMAC.value = mac;
}
</script>
</head>
<body onload="init();">
<form name = 'fm'>
通过JavaScript获取的IP信息：<input type ='text' name = 'clientIP'><br>
通过JavaScript获取的MAC信息：<input type='text'name = 'clientMAC'>
通过JSP获取的IP信息：<%= request.getRemoteAddr() %>
</form>
</body>
</html>

JavaScript Engines: Comparing Implementations
Apr 13, 2025 am 12:05 AM
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.
Python vs. JavaScript: The Learning Curve and Ease of Use
Apr 16, 2025 am 12:12 AM
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.
From C/C to JavaScript: How It All Works
Apr 14, 2025 am 12:05 AM
The 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.
JavaScript and the Web: Core Functionality and Use Cases
Apr 18, 2025 am 12:19 AM
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.
JavaScript in Action: Real-World Examples and Projects
Apr 19, 2025 am 12:13 AM
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.
Understanding the JavaScript Engine: Implementation Details
Apr 17, 2025 am 12:05 AM
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 vs. JavaScript: Community, Libraries, and Resources
Apr 15, 2025 am 12:16 AM
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.
Python vs. JavaScript: Development Environments and Tools
Apr 26, 2025 am 12:09 AM
Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.
