javascript - target="_blank"与target="blank"原来是有区别的啊!
target="_blank"
在新标签打开链接
一直以为target="blank"
是错误的写法,没想到这样写还有效果啊:
当标签已经打开了,点击第二次就不会再打开新标签了,而是刷新之前的那个标签啊,怎么这么神奇,特异功能啊!
去查了一下,target
标准属性没有blank
这个值啊,真是奇怪。
希望大神指点一下哈
PS:好像现在HTML5
有种类似的功能,像网易音乐那样点击链接不会刷新页面,不会中断当前正在播放的音乐,还能变动URL
,不知道这个效果是神马原理

_blank 是打开个新页面
blank 是打开个页面,并命名为为 blank,当存在 blank页面的时候,则跟新页面(这里换成其他非_blank,_top 等)也是可以的
target
属性设置非_blank
、_top
这些预定义的值就是指定打开链接的窗口的名称,如果不存在就新建窗口,如果已存在就在该窗口中打开。
对于现代浏览器来说,“窗口”指的就是“标签页”。
yqb 的回答是正确的。
target 预定义的取值有四个。其他的值则表示 framename,即在指定的框架中打开链接,如指定的框架不存在,就会新建一个页面/标签页作为该框架。

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

The roles of HTML, CSS and JavaScript in web development are: 1. HTML defines the web page structure, 2. CSS controls the web page style, and 3. JavaScript adds dynamic behavior. Together, they build the framework, aesthetics and interactivity of modern websites.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.
