How Can I Tell the Difference Between CSS Selectors and jQuery Filters?

CSS Selectors vs. jQuery Filters

It is possible to pass CSS selectors to the jQuery function, as seen in:

jQuery('h1 + h2');

jQuery also has filters such as :even and :odd:

jQuery('tr:even');

Differentiating Between Selectors and Filters

While jQuery filters always use a colon (:), some CSS selectors also use it. Examples include:

• :last-child
• :root
• :empty
• :target

Identify CSS Selectors from jQuery Filters

There is no straightforward syntax rule to differentiate between CSS selectors and jQuery filters. However, there are some tips to help identify them:

• Match-Based Filters:

  • Selectors that apply to elements based on their position or order within a set
  • Examples: :eq(), :gt(), :lt(), :even, :odd

• Standard Pseudo-Classes:

  • Selectors that apply to elements based on their structure or content
  • Examples: :first-child, :last-child, :nth-child()

Ambiguity in jQuery Selectors

The jQuery selectors category called "Basic Filters" includes both match-based filters and standard pseudo-classes, which can be confusing. Always refer to the jQuery documentation to determine the specific behavior of a selector.
