jQuery Core Methods
About This Index
This page is the jQuery Core index for the tutorial track. Each row links to a full guide with syntax, examples, and FAQs.
Learn the jQuery overview on /jquery. Use this page when you need a Core API such as jQuery(), .ready(), or $.noConflict().
Start with jQuery() / $(), then .ready()—learn $.noConflict() only if another library conflicts on $.
How to Call a Core Method
Use the factory to select, create, wrap, or wait for the DOM:
$("p"); // select
$(""); // create
$(document.getElementById("app")); // wrap
$(function () {
console.log("DOM ready");
});
var jq = $.noConflict();
jq("body").addClass("ready");jQuery Core Methods Table

Factory Function
1 methodThe entry point to every jQuery program — select, create, wrap, or wait for the DOM.
| Method | Description | Tutorial |
|---|---|---|
jQuery() / $() | Create a collection from a CSS selector, HTML string, DOM node, array, object, or ready callback. | Try it |
Document Ready
3 methodsRun code when the DOM is safe, pause ready for loaders, and handle ready-handler errors.
| Method | Description | Tutorial |
|---|---|---|
.ready() | Run a callback when the DOM is ready — prefer $(fn) since jQuery 3.0. | Try it |
$.holdReady() | Hold or release the ready event — deprecated in 3.2; prefer $.when($.ready, promise). | Try it |
$.readyException() | Handle errors thrown synchronously inside ready handlers — override to log instead of rethrow. | Try it |
Globals & Aliases
1 methodShare the page with other libraries that also want $.
| Method | Description | Tutorial |
|---|---|---|
$.noConflict() | Release the $ alias (and optionally the jQuery name) for other libraries. | Try it |
