within
Scopes all subsequent cy commands to within this element. Useful when working
within a particular group of elements such as a <form>
.
It is unsafe to
chain further commands that rely on the subject after .within()
.
Syntax​
.within(callbackFn)
.within(options, callbackFn)
Usage​
Correct Usage
cy.get('.list')
.first()
.within(($list) => {}) // Yield the first `.list` and scope all commands within it
Incorrect Usage
cy.within(() => {}) // Errors, cannot be chained off 'cy'
cy.getCookies().within(() => {}) // Errors, 'getCookies' does not yield DOM element
cy.get('div').within(($divs) => {}) // Probably errors, because get('div') yields multiple elements
Arguments​
callbackFn (Function)
Pass a function that takes the current yielded subject as its first argument.
options (Object)
Pass in an options object to change the default behavior of .within()
.
Option | Default | Description |
---|---|---|
log | true | Displays the command in the Command log |
Yields ​
.within()
yields the same subject it was given.- It is unsafe
to chain further commands that rely on the subject after
.within()
.
Trying to return a different element the .within
callback have no effect:
<div id="within-yields">
The parent div
<div class="some-child">Child element</div>
</div>
cy.get('#within-yields')
.within(() => {
// we are trying to return something
// from the .within callback,
// but it won't have any effect
return cy.contains('Child element').should('have.class', 'some-child')
})
.should('have.id', 'within-yields')
Similarly, trying to change the subject by using the
cy.wrap command inside the .within
callback have no
effect:
<div id="wrap-inside-within">
The parent div
<div class="some-child">Child element</div>
</div>
cy.get('#wrap-inside-within')
.within(() => {
// returning cy.wrap(...) has no effect on the yielded value
// it will still be the original parent DOM element
return cy.wrap('a new value')
})
.should('have.id', 'wrap-inside-within')
Examples​
Forms​
Get inputs within a form and submit the form​
<form>
<input name="email" type="email" />
<input name="password" type="password" />
<button type="submit">Login</button>
</form>
cy.get('form').within(($form) => {
// you have access to the found form via
// the jQuery object $form if you need it
// cy.get() will only search for elements within form,
// not within the entire document
cy.get('input[name="email"]').type('[email protected]')
cy.get('input[name="password"]').type('password')
cy.root().submit()
})
Tables​
Find row with specific cell and confirm other cells in the row​
<table>
<tr>
<td>My first client</td>
<td>My first project</td>
<td>0</td>
<td>Active</td>
<td><button>Edit</button></td>
</tr>
</table>
cy.contains('My first client')
.parent('tr')
.within(() => {
// all searches are automatically rooted to the found tr element
cy.get('td').eq(1).contains('My first project')
cy.get('td').eq(2).contains('0')
cy.get('td').eq(3).contains('Active')
cy.get('td').eq(4).contains('button', 'Edit').click()
})
Temporarily escape​
You can temporarily escape the .within
context by starting a new command chain
with cy.root followed by .closest
commands.
<section class="example">
{/* note the input field outside the form */}
<input id="name" type="text" />
<form>
<input name="email" type="email" />
<input name="password" type="password" />
<button type="submit">Login</button>
</form>
</section>
cy.get('form').within(($form) => {
// temporarily escape the .within context
cy.root().closest('.example').find('#name').type('Joe')
// continue using the .within context
cy.get('input[name="email"]').type('[email protected]')
cy.get('input[name="password"]').type('password')
cy.root().submit()
})
Rules​
Requirements ​
.within()
requires being chained off a previous command that yields exactly one DOM element.
Assertions ​
.within()
will only run assertions you have chained once, and will not retry.
Timeouts ​
.within()
cannot time out.
Command Log​
Get the input within the form
cy.get('.query-form').within((el) => {
cy.get('input:first')
})
The commands above will display in the Command Log as:
When clicking on the within
command within the command log, the console
outputs the following:
