jQuery selectors are powerful tools that every developer uses in daily life. They can accurately select the required elements from the DOM. This list brings together 50 commonly used jQuery selectors for reference by all jQuery developers. Note that these selectors are not arranged in a specific order.
-
$(“*”)– Select all elements in the document. -
$(“p > *”)– Select the child elements of all paragraph elements. -
$(“#specialID”)– Select the element with ID "specialID". -
$(“.specialClass”)– Select all elements with class as "specialClass". -
$(“l(fā)i:not(.myclass)”)– Select all elements that match theliselector, but exclude elements whose class is "myclass". -
$(“a#specialID.specialClass”)– Select the link element with ID "specialID" and class "specialClass". -
$(“p a.specialClass”)– Select the link element within the paragraph element with class "specialClass". -

jQuery Selector FAQs (FAQs)
What is the difference between an attribute equal to a selector and an attribute including a selector?
Theattribute equals the selector to select an element whose attribute value exactly matches a specific value, such as selecting an element with a specific ID or class. The attribute contains selector is used to select the element that contains the specified substring, even if the value is only part of the attribute value.
How to use jQuery to select elements by name?
Use attribute equals selector: $(“element[name=’value’]”). For example, select the input element named "username": $(“input[name=’username’]”).
What is the property starter selector?
Attribute Start Selector is used to select an element whose attribute value begins with a specified string: $(“element[attribute^=’value’]”). For example, select all elements whose ID starts with "my": $(“[id^=’my’]”).
How to select multiple elements in jQuery?
Separate selectors with commas: $(“div, p”) Select all div and p elements.
How to select the first child element of an element?
Use :first-childSelector: $(“element:first-child”).
How to select the last child element of an element?
Use :last-childSelector: $(“element:last-child”).
How to select all even elements?
Use :evenSelector: $(“element:even”).
How to select all odd elements?
Use :oddSelector: $(“element:odd”).
How to select elements that contain specific text?
Use :contains()Selector: $(“element:contains(‘text’)”).
How to select elements with specific attributes?
Use attribute selector: $(“element[attribute]”).

How to make an HTTP request in Node.js?
Jul 13, 2025 am 02:18 AM
There are three common ways to initiate HTTP requests in Node.js: use built-in modules, axios, and node-fetch. 1. Use the built-in http/https module without dependencies, which is suitable for basic scenarios, but requires manual processing of data stitching and error monitoring, such as using https.get() to obtain data or send POST requests through .write(); 2.axios is a third-party library based on Promise. It has concise syntax and powerful functions, supports async/await, automatic JSON conversion, interceptor, etc. It is recommended to simplify asynchronous request operations; 3.node-fetch provides a style similar to browser fetch, based on Promise and simple syntax
JavaScript Data Types: Primitive vs Reference
Jul 13, 2025 am 02:43 AM
JavaScript data types are divided into primitive types and reference types. Primitive types include string, number, boolean, null, undefined, and symbol. The values are immutable and copies are copied when assigning values, so they do not affect each other; reference types such as objects, arrays and functions store memory addresses, and variables pointing to the same object will affect each other. Typeof and instanceof can be used to determine types, but pay attention to the historical issues of typeofnull. Understanding these two types of differences can help write more stable and reliable code.
JavaScript time object, someone builds an eactexe, faster website on Google Chrome, etc.
Jul 08, 2025 pm 02:27 PM
Hello, JavaScript developers! Welcome to this week's JavaScript news! This week we will focus on: Oracle's trademark dispute with Deno, new JavaScript time objects are supported by browsers, Google Chrome updates, and some powerful developer tools. Let's get started! Oracle's trademark dispute with Deno Oracle's attempt to register a "JavaScript" trademark has caused controversy. Ryan Dahl, the creator of Node.js and Deno, has filed a petition to cancel the trademark, and he believes that JavaScript is an open standard and should not be used by Oracle
Handling Promises: Chaining, Error Handling, and Promise Combinators in JavaScript
Jul 08, 2025 am 02:40 AM
Promise is the core mechanism for handling asynchronous operations in JavaScript. Understanding chain calls, error handling and combiners is the key to mastering their applications. 1. The chain call returns a new Promise through .then() to realize asynchronous process concatenation. Each .then() receives the previous result and can return a value or a Promise; 2. Error handling should use .catch() to catch exceptions to avoid silent failures, and can return the default value in catch to continue the process; 3. Combinators such as Promise.all() (successfully successful only after all success), Promise.race() (the first completion is returned) and Promise.allSettled() (waiting for all completions)
What is the cache API and how is it used with Service Workers?
Jul 08, 2025 am 02:43 AM
CacheAPI is a tool provided by the browser to cache network requests, which is often used in conjunction with ServiceWorker to improve website performance and offline experience. 1. It allows developers to manually store resources such as scripts, style sheets, pictures, etc.; 2. It can match cache responses according to requests; 3. It supports deleting specific caches or clearing the entire cache; 4. It can implement cache priority or network priority strategies through ServiceWorker listening to fetch events; 5. It is often used for offline support, speed up repeated access speed, preloading key resources and background update content; 6. When using it, you need to pay attention to cache version control, storage restrictions and the difference from HTTP caching mechanism.
JS roundup: a deep dive into the JavaScript event loop
Jul 08, 2025 am 02:24 AM
JavaScript's event loop manages asynchronous operations by coordinating call stacks, WebAPIs, and task queues. 1. The call stack executes synchronous code, and when encountering asynchronous tasks, it is handed over to WebAPI for processing; 2. After the WebAPI completes the task in the background, it puts the callback into the corresponding queue (macro task or micro task); 3. The event loop checks whether the call stack is empty. If it is empty, the callback is taken out from the queue and pushed into the call stack for execution; 4. Micro tasks (such as Promise.then) take precedence over macro tasks (such as setTimeout); 5. Understanding the event loop helps to avoid blocking the main thread and optimize the code execution order.
Understanding Event Bubbling and Capturing in JavaScript DOM events
Jul 08, 2025 am 02:36 AM
Event bubbles propagate from the target element outward to the ancestor node, while event capture propagates from the outer layer inward to the target element. 1. Event bubbles: After clicking the child element, the event triggers the listener of the parent element upwards in turn. For example, after clicking the button, it outputs Childclicked first, and then Parentclicked. 2. Event capture: Set the third parameter to true, so that the listener is executed in the capture stage, such as triggering the capture listener of the parent element before clicking the button. 3. Practical uses include unified management of child element events, interception preprocessing and performance optimization. 4. The DOM event stream is divided into three stages: capture, target and bubble, and the default listener is executed in the bubble stage.
A JS roundup of higher-order functions beyond map and filter
Jul 10, 2025 am 11:41 AM
In JavaScript arrays, in addition to map and filter, there are other powerful and infrequently used methods. 1. Reduce can not only sum, but also count, group, flatten arrays, and build new structures; 2. Find and findIndex are used to find individual elements or indexes; 3.some and everything are used to determine whether conditions exist or all meet; 4.sort can be sorted but will change the original array; 5. Pay attention to copying the array when using it to avoid side effects. These methods make the code more concise and efficient.
