How to Add Query Strings to Fetch GET Requests?
Query Strings with Fetch GET Request
The Fetch API provides a modern approach to making HTTP requests in JavaScript. By default, GET requests made using Fetch do not include query string parameters. To add a query string to a GET request, we can either use the URLSearchParams interface or concatenate the query string manually.
Using URLSearchParams:
The URLSearchParams interface allows us to easily create and manipulate query strings. To add a query string parameter, we can use the set() method:
const searchParams = new URLSearchParams();
searchParams.set('order_id', 1);
const request = new Request({
url: 'http://myapi.com/orders',
method: 'GET',
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
},
body: searchParams.toString()
});
fetch(request);
Concatenating the Query String:
Alternatively, we can concatenate the query string directly to the request URL:
const request = new Request({
url: 'http://myapi.com/orders?order_id=1',
method: 'GET'
});
fetch(request);
Note: If you choose to concatenate the query string manually, ensure that it is properly encoded to prevent invalid characters from breaking the request.

Advanced Conditional Types in TypeScript
Aug 04, 2025 am 06:32 AM
TypeScript's advanced condition types implement logical judgment between types through TextendsU?X:Y syntax. Its core capabilities are reflected in the distributed condition types, infer type inference and the construction of complex type tools. 1. The conditional type is distributed in the bare type parameters and can automatically split the joint type, such as ToArray to obtain string[]|number[]. 2. Use distribution to build filtering and extraction tools: Exclude excludes types through TextendsU?never:T, Extract extracts commonalities through TextendsU?T:Never, and NonNullable filters null/undefined. 3

How to find the length of an array in JavaScript?
Jul 26, 2025 am 07:52 AM
To get the length of a JavaScript array, you can use the built-in length property. 1. Use the .length attribute to return the number of elements in the array, such as constfruits=['apple','banana','orange'];console.log(fruits.length);//Output: 3; 2. This attribute is suitable for arrays containing any type of data such as strings, numbers, objects, or arrays; 3. The length attribute will be automatically updated, and its value will change accordingly when elements are added or deleted; 4. It returns a zero-based count, and the length of the empty array is 0; 5. The length attribute can be manually modified to truncate or extend the array,

Understanding JavaScript's Proxy and Reflect APIs
Jul 26, 2025 am 07:55 AM
Proxy and Reflect API are powerful tools used in JavaScript to intercept and customize object operations; 1. Proxy blocks operations such as get, set by wrapping target objects and defining "traps", and implements functions such as logs, verification, read-only control; 2. Reflect provides methods corresponding to Proxy traps to ensure the consistency and correctness of default behaviors and improve code maintainability; 3. Practical applications include Vue3 responsive system, data verification, debug logs, immutable objects and API simulation; 4. Pay attention to performance overhead, complex behavior of built-in objects, this binding problems, and nested objects need to be recursively proxyed; 5. Reasonable use can build efficient, debugable, and reactive
Generate Solved Double Chocolate Puzzles: A Guide to Data Structures and Algorithms
Aug 05, 2025 am 08:30 AM
This article explores in-depth how to automatically generate solveable puzzles for the Double-Choco puzzle game. We will introduce an efficient data structure - a cell object based on a 2D grid that contains boundary information, color, and state. On this basis, we will elaborate on a recursive block recognition algorithm (similar to depth-first search) and how to integrate it into the iterative puzzle generation process to ensure that the generated puzzles meet the rules of the game and are solveable. The article will provide sample code and discuss key considerations and optimization strategies in the generation process.

How can you remove a CSS class from a DOM element using JavaScript?
Aug 05, 2025 pm 12:51 PM
The most common and recommended method for removing CSS classes from DOM elements using JavaScript is through the remove() method of the classList property. 1. Use element.classList.remove('className') to safely delete a single or multiple classes, and no error will be reported even if the class does not exist; 2. The alternative method is to directly operate the className property and remove the class by string replacement, but it is easy to cause problems due to inaccurate regular matching or improper space processing, so it is not recommended; 3. You can first judge whether the class exists and then delete it through element.classList.contains(), but it is usually not necessary; 4.classList
