jquery json asynchronous

There are two ways for jQuery to asynchronously obtain json data, one is the $.getJSON method and the other is the $.ajax method. This article uses these two methods to asynchronously obtain json data and then append it to the page.

Create the data.json file in the root directory:

Copy code The code is as follows:

{
"one" : "Hello",
"two" : "World"
}

■ Get json data through $.getJSON method

Copy code The code is as follows:



■ Obtain json data through $.ajax method

Copy code The code is as follows:

   
   

总结:使用$.getJSON方法和$.ajax方法都能达到相同的效果,但是,如果想对异步获取的过程有更细节的控制,推荐使用$.ajax方法。

In-depth understanding of PHP: Implementation method of converting JSONUnicode to Chinese During development, we often encounter situations where we need to process JSON data, and Unicode encoding in JSON will cause us some problems in some scenarios, especially when Unicode needs to be converted When encoding is converted to Chinese characters. In PHP, there are some methods that can help us achieve this conversion process. A common method will be introduced below and specific code examples will be provided. First, let us first understand the Un in JSON

Advanced Guide to Python asyncio: From Beginner to Expert Advanced Guide to Python asyncio: From Beginner to Expert Mar 04, 2024 am 09:43 AM

Concurrent and Asynchronous Programming Concurrent programming deals with multiple tasks executing simultaneously, asynchronous programming is a type of concurrent programming in which tasks do not block threads. asyncio is a library for asynchronous programming in python, which allows programs to perform I/O operations without blocking the main thread. Event loop The core of asyncio is the event loop, which monitors I/O events and schedules corresponding tasks. When a coroutine is ready, the event loop executes it until it waits for I/O operations. It then pauses the coroutine and continues executing other coroutines. Coroutines Coroutines are functions that can pause and resume execution. The asyncdef keyword is used to create coroutines. The coroutine uses the await keyword to wait for the I/O operation to complete. The following basics of asyncio

PHP Tutorial: How to Convert JSON Unicode to Chinese Characters PHP Tutorial: How to Convert JSON Unicode to Chinese Characters Mar 05, 2024 pm 06:36 PM

JSON (JavaScriptObjectNotation) is a lightweight data exchange format commonly used for data exchange between web applications. When processing JSON data, we often encounter Unicode-encoded Chinese characters (such as "u4e2du6587") and need to convert them into readable Chinese characters. In PHP, we can achieve this conversion through some simple methods. Next, we will detail how to convert JSONUnico

Quick tips for converting PHP arrays to JSON Quick tips for converting PHP arrays to JSON May 03, 2024 pm 06:33 PM

PHP arrays can be converted to JSON strings through the json_encode() function (for example: $json=json_encode($array);), and conversely, the json_decode() function can be used to convert from JSON to arrays ($array=json_decode($json);) . Other tips include avoiding deep conversions, specifying custom options, and using third-party libraries.

Asynchronous and non-blocking technology in Java exception handling Asynchronous and non-blocking technology in Java exception handling May 01, 2024 pm 05:42 PM

Asynchronous and non-blocking techniques can be used to complement traditional exception handling, allowing the creation of more responsive and efficient Java applications: Asynchronous exception handling: Handling exceptions in another thread or process, allowing the main thread to continue executing, avoiding blocking. Non-blocking exception handling: involves event-driven exception handling when an I/O operation goes wrong, avoiding blocking threads and allowing the event loop to handle exceptions.
