Definition and Usage

The querySelectorAll() method returns all elements in the document that matches a specified CSS selector(s), as a static NodeList object.

The NodeList object represents a collection of nodes. The nodes can be accessed by index numbers. The index starts at 0.

Tip: You can use the length property of the NodeList object to determine the number of elements that matches the specified selector, then you can loop through all elements and extract the info you want.

For more information about CSS Selectors, visit our CSS Selectors Tutorial and our CSS Selectors Reference.

// Get all <p> elements in the document with class="example"
var x = document.querySelectorAll("p.example");

// Set the background color of the first <p> element with class="example" (index 0)
x[0].style.backgroundColor = "red";
