Let me tell you a method and technique for using JavaScript to modify the browser title. Friends who need it can test the code.
title is a special node element in HTML. Because it can use document.getElementsByTagName("title")[0] to get the title tag of the web page, but it cannot use document.getElementsByTagName("title") [0].innerHtml is used to change its value. After testing, there are two ways to modify native js, and it can also be easily set in jQuery. Friends who are not sure can find out.
innerText method
Through console.log(document.getElementsByTagName("title")[0]), I found that the
label can be printed. There are only text nodes in the label, so I guess Only TextNode can be recognized, so setting the value of title using innerText method was successful. </p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'>document.getElementsByTagName("title")[0].innerText = '需要设置的值';</pre><div class="contentsignin">Copy after login</div></div><p>document.title method</p><p>After testing, the value of title can also be set through document.title. </p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'>console.log(document.title); # 可以获取title的值。
document.title = '需要设置的值'; # 设置title的值。</pre><div class="contentsignin">Copy after login</div></div><p>Example</p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'>window.onfocus = function () {
document.title = '恢复正常了...';
};
window.onblur = function () {
document.title = '快回来~页面崩溃了';
};</pre><div class="contentsignin">Copy after login</div></div><p>We change the value of title when the browser gains focus and loses focus. You can find that the title changes when switching browser tabs. </p><p>jQuery method</p><p>Of course, if your project relies on jQuery, you can use the jq method to set it</p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'>$('title').html('')
$('title').text('')</pre><div class="contentsignin">Copy after login</div></div><p>Both methods can be implemented in jq</p>
<p> Summary</p>
<p>In native js, we can dynamically modify the title of the web page through innerText and document.title.</p>
<p>In jq, we can use $('title').html('') Or $('title').text('') to modify. </p>
<p>The above is what I compiled for everyone. I hope it will be helpful to everyone in the future. </p>

<p class="Articlelist_txts_p">Apache server is a powerful web server software that acts as a bridge between browsers and website servers. 1. It handles HTTP requests and returns web page content based on requests; 2. Modular design allows extended functions, such as support for SSL encryption and dynamic web pages; 3. Configuration files (such as virtual host configurations) need to be carefully set to avoid security vulnerabilities, and optimize performance parameters, such as thread count and timeout time, in order to build high-performance and secure web applications.</p>

<span class="Articlelist_txts_time">Apr 18, 2025 am 09:24 AM</span>
<p class="Articlelist_txts_p">When developing websites using CraftCMS, you often encounter resource file caching problems, especially when you frequently update CSS and JavaScript files, old versions of files may still be cached by the browser, causing users to not see the latest changes in time. This problem not only affects the user experience, but also increases the difficulty of development and debugging. Recently, I encountered similar troubles in my project, and after some exploration, I found the plugin wiejeben/craft-laravel-mix, which perfectly solved my caching problem.</p>

<p class="Articlelist_txts_p">Nginx performance monitoring and troubleshooting are mainly carried out through the following steps: 1. Use nginx-V to view version information, and enable the stub_status module to monitor the number of active connections, requests and cache hit rate; 2. Use top command to monitor system resource occupation, iostat and vmstat monitor disk I/O and memory usage respectively; 3. Use tcpdump to capture packets to analyze network traffic and troubleshoot network connection problems; 4. Properly configure the number of worker processes to avoid insufficient concurrent processing capabilities or excessive process context switching overhead; 5. Correctly configure Nginx cache to avoid improper cache size settings; 6. By analyzing Nginx logs, such as using awk and grep commands or ELK</p>

This article will introduce several commonly used methods to help you choose the most suitable solution. 1. Use Hadoop’s own WebUI, Hadoop’s own Web interface to provide cluster status monitoring function. Steps: Make sure the Hadoop cluster is up and running. Access the WebUI: Enter http://:50070 (Hadoop2.x) or http://:9870 (Hadoop3.x) in your browser. The default username and password are usually hdfs/hdfs. 2.

<p class="Articlelist_txts_p">This article describes how to analyze Nginx logs to improve website performance and user experience. 1. Understand the Nginx log format, such as timestamps, IP addresses, status codes, etc.; 2. Use tools such as awk to parse logs and count indicators such as visits, error rates, etc.; 3. Write more complex scripts according to needs or use more advanced tools, such as goaccess, to analyze data from different dimensions; 4. For massive logs, consider using distributed frameworks such as Hadoop or Spark. By analyzing logs, you can identify website access patterns, improve content strategies, and ultimately optimize website performance and user experience.</p>
