Analysis on the usage of append() and appendto() in jquery
这篇文章主要介绍了jquery中append()与appendto()用法分析,以实例的形式分析了jquery中append()与appendto()的具体语法与详细用法,需要的朋友可以参考下
本文实例分析了jquery中append()与appendto()的用法。分享给大家供大家参考。具体分析如下:
在jQuery的文档操作方法中,append()和appentto()方法执行的任务相同,但是两者也有区别。
1、append()方法:在被选元素的结尾(但仍在元素内部)插入指定的内容。
a、语法:
代码如下:
$(selector).append(content);
其中,参数content是必需的,指定要附加的内容。
b、append能够使用函数给被选元素附加内容,语法为:
代码如下:
$(selector).append(function(index,html));
其中,function()是必需的,参数index和html都是可选的。index表示接收选择器的index位置,html表示接收选择器的当前html。
例子:
代码如下:
<html> <head> <script type="text/ javascript " src="/jquery/jquery.js"></script> <script type="text/javascript"> $( document ).ready(function(){ $("button").click(function(){ $("p").append(" <b>Hello jQuery!</b>"); }); }); </script> </head> <body> <p>This is a paragraph.</p> <p>This is another paragraph.</p> <button>在每个 p 元素的结尾添加内容</button> </body> </html>
运行结果如下:
This is a paragraph. Hello jQuery!
This is another paragraph. Hello jQuery!
2、appendto()方法:在被选元素的结尾(但仍在元素的内部)插入指定的内容。但不能使用函数来附加内容。
语法:
代码如下:
$(content).appendto(selector);
例子:
代码如下:
<html> <head> <script type="text/javascript" src="/jquery/jquery.js"></script> <script type="text/javascript"> $(document).ready(function(){ $("button").click(function(){ $("<b> Hello jQuery!</b>").appendTo("p"); }); }); </script> </head> <body> <p>This is a paragraph.</p> <p>This is another paragraph.</p> <button>在每个 p 元素的结尾添加内容</button> </body> </html>
运行结果如下:
This is a paragraph. Hello jQuery!
This is another paragraph. Hello jQuery!

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),
