Cheat Sheet
- Powerful Selector Syntax -
Popular selectors will appear on your jquery exam, so review CSS-based selectors like $("#id"), $(".class"), and $("tag") for precise DOM targeting (MDN Web Docs). Remember the order "ID first (#), then class (.), then tag" and combine selectors (e.g., $("form input.required")) to narrow results effectively.
- Event Handling and Delegation -
Event questions on a javascript jquery test often focus on .click() versus .on("click",…) and delegated events (jQuery official docs). Use $(parent).on("click", "child", handler) to bind events to future elements and recall "Delegate up to level up" as a mnemonic for bubbling-based delegation.
- Chaining and Method Return Values -
Chaining is a staple of any jQuery quiz - remember the "write less, do more" mantra from the jQuery API. Since most methods return the jQuery object, you can chain calls like $("#nav").addClass("active").slideDown(200) to keep code concise and readable.
- AJAX Requests Simplified -
AJAX functions like $.ajax(), $.get(), and $.post() are staples of the jQuery test and JavaScript trivia quiz (W3C recommendations). Use the "Type, URL, Data" mnemonic (e.g., $.get("/api/items", {id:1}, callback)) and handle success/error callbacks to build robust async calls.
- DOM Traversal Techniques -
DOM traversal methods such as .find(), .parent(), .siblings(), and .closest() are frequently tested on the jquery exam (DOM Level 3 spec). For example, $("#menu").find("li").last() targets the last list item - use these methods instead of manual loops for cleaner code.
