filter

Get the DOM elements that match a specific selector.

Opposite of .not()

The querying behavior of this command matches exactly how .filter() works in jQuery.

Syntax

.filter(selector)
.filter(selector, options)

Usage

Correct Usage

cy.get('td').filter('.users') // Yield all el's with class '.users'

Incorrect Usage

cy.filter('.animated') // Errors, cannot be chained off 'cy'
cy.clock().filter() // Errors, 'clock' does not yield DOM elements

Arguments

selector (String selector)

A selector used to filter matching DOM elements.

options (Object)

Pass in an options object to change the default behavior of .filter().

Option	Default	Description
`log`	`true`	Displays the command in the Command log
`timeout`	`defaultCommandTimeout`	Time to wait for `.filter()` to resolve before timing out

Yields

.filter() yields the new DOM element(s) it found.
.filter() is a query, and it is safe to chain further methods.

Examples

Selector

Filter the current subject to the elements with the class 'active'

<ul>
  <li>Home</li>
  <li class="active">About</li>
  <li>Services</li>
  <li>Pricing</li>
  <li>Contact</li>
</ul>

// yields <li>About</li>
cy.get('ul').find('>li').filter('.active')

Contains

Filter by text

You can use the jQuery

selector to perform a case-sensitive text substring match.

<ul>
  <li>Home</li>
  <li>Services</li>
  <li>Advanced Services</li>
  <li>Pricing</li>
  <li>Contact</li>
</ul>

Let's find both list items that contain the work "Services"

cy.get('li').filter(':contains("Services")').should('have.length', 2)

Non-breaking space

If the HTML contains a non-breaking space entity   and the test uses the jQuery

selector, then the test needs to use the Unicode value \u00a0 instead of  .

<div data-testid="testattr">
  <span>Hello&nbsp;world</span>
</div>

cy.get('[data-testid="testattr"]').filter(':contains("Hello\u00a0world")')

Rules

Requirements

.filter() requires being chained off a command that yields DOM element(s).

Assertions

.filter() will automatically retry until the element(s) exist in the DOM
.filter() will automatically retry until all chained assertions have passed

Timeouts

.filter() can time out waiting for the element(s) to exist in the DOM .
.filter() can time out waiting for assertions you've added to pass.

Command Log

Filter the li's to the li with the class 'active'.

cy.get('.left-nav>.nav').find('>li').filter('.active')

The commands above will display in the Command Log as:

When clicking on the filter command within the command log, the console outputs the following:
