How to check if element exists using Cypress.io
JavascriptSelenium WebdriverCypressJavascript Problem Overview
How to check if element is present or not, so that certain steps can be performed if element is present. Else certain different steps can be performed if element is not present.
I tried something like below but it didn't work:
Cypress.Commands.add('deleteSometheingFunction', () => {
cy.get('body').then($body => {
if ($body.find(selectors.ruleCard).length) {
let count = 0;
cy.get(selectors.ruleCard)
.each(() => count++)
.then(() => {
while (count-- > 0) {
cy.get('body')
// ...
// ...
}
});
}
});
});
I am looking for a simple solution, which can be incorporated with simple javascript if else block or then() section of the promise
Something similar to Webdriver protocol's below implementions:
driver.findElements(By.yourLocator).size() > 0
- check for presenece of element in wait
Kindly advise. Thanks

Solution 1 - Javascript
I'll just add that if you decide to do if condition by checking the .length
property of cy.find
command, you need to respect the asynchronous nature of cypress.
Example: Following condition evaluates as false despite appDrawerOpener button exists
if (cy.find("button[data-cy=appDrawerOpener]").length > 0) //evaluates as false
But this one evaluates as true because $body
variable is already resolved as you're in .then()
part of the promise:
cy.get("body").then($body => {
if ($body.find("button[data-cy=appDrawerOpener]").length > 0) {
//evaluates as true
}
});

Solution 2 - Javascript
it has been questioned before: https://stackoverflow.com/questions/55541171/conditional-statement-in-cypress
Thus you can basically try this:
cy.get('header').then(($a) => {
if ($a.text().includes('Account')) {
cy.contains('Account')
.click({force:true})
} else if ($a.text().includes('Sign')) {
cy.contains('Sign In')
.click({force:true})
} else {
cy.get('.navUser-item--account .navUser-action').click({force:true})
}
})

cypress all steps are async ,, so that you should make common function in commands file or page object file,,..
export function checkIfEleExists(ele){
return new Promise((resolve,reject)=>{
/// here if ele exists or not
cy.get('body').find( ele ).its('length').then(res=>{
if(res > 0){
//// do task that you want to perform
cy.get(ele).select('100').wait(2000);
resolve();
}else{
reject();
}
});
})
}
// here check if select[aria-label="rows per page"] exists
cy.checkIfEleExists('select[aria-label="rows per page"]')
.then(e=>{
//// now do what if that element is in ,,..
})
.catch(e=>{
////// if not exists...
})

I found a solution, hope it helps!
You can use this:
cy.window().then((win) => {
const identifiedElement = win.document.querySelector(element)
cy.log('Object value = ' + identifiedElement)
});
You can add this to your commands.js file in Cypress
Cypress.Commands.add('isElementExist', (element) => {
cy.window().then((win) => {
const identifiedElement = win.document.querySelector(element)
cy.log('Object value = ' + identifiedElement)
});
})
Solution 5 - Javascript
Using async/await gives a clean syntax:
const $el = await cy.find("selector")
if ($el.length > 0) {
...
