Cypress: Feature request: paste text into textarea

[kgish]

Currently it is only possible to enter text into a textarea by using the type() method. For larger amounts of text this can be quite cumbersome, as each character is inserted separately, even if the delay is reduced, e.g.{delay: 0}.

To speed up this action, it'd be nice if all of the text could be pasted into the textarea in one go, without having to enter the text one character at a time.

Therefore, I'd like to propose a new method called paste() which inserts larger amounts of text in one go.

Thanks in advance for considering this.

Can you just put "el.value = text" command?

This is the proposal for what you're asking about: https://github.com/cypress-io/cypress/issues/566

We won't do cy.paste, we'll simply make cy.type type synchronously which would type all the characters in one shot (and make that the default).

Currently as @bahmutov suggests just do cy.get('textarea').invoke('val', myValue').trigger('change')

[bahmutov]

That's right - with Cypress you have _full and immediate_ access to the DOM so you can do anything you can do from the devtools

@brian-mann when using your approach I find that the fields in my form get filled but they're not picked up by the Vue.js two-way binding (which does work when using cy.type. Is there an alternative?

[slaby93]

@nachocab Same with react-form -> it does not pickup this paste.

@bahmutov Maybe I'm doing it wrong, but in the console I can do $0.textContent = 'really long text' and I see the text appear in my contenteditable, but when I run it in Cypress it doesn't do anything:

cy.get(`.beam-sequence > .beam--current [contenteditable]`).then($span => {
      $span.textContent = 'really long text';
});

[nachocab]

Ah, never mind. I caught my mistake. This works:

cy.get(`.beam-sequence > .beam--current [contenteditable]`).then($span => {
      $span.text('really long text');
});

I realize this is closed, but for those mentioning they couldn't get change detection to work with some of the SPA libraries/frameworks, here's what worked for me with Angular:

cy.get('[data-cy=markdown-textarea]').clear().invoke('val', text).trigger('input');

Thank you @DanWahlin. I have been trying so many things. Yours did it!

[DanWahlin]

Glad that helped!

Should this works fine instead of type({cmd} v)

/**
 * Simulates a paste event.
 *
 * @param pasteOptions Set of options for a simulated paste event.
 * @param pasteOptions.destinationSelector Selector representing the DOM element that the paste event should be dispatched to.
 * @param pasteOptions.pastePayload Simulated data that is on the clipboard.
 * @param pasteOptions.pasteFormat The format of the simulated paste payload. Default value is 'text'.
 */
function paste({ destinationSelector, pastePayload, pasteType = 'text' }) {
    // https://developer.mozilla.org/en-US/docs/Web/API/Element/paste_event
    cy.get(destinationSelector).then($destination => {
        const pasteEvent = Object.assign(new Event('paste', { bubbles: true, cancelable: true }), {
            clipboardData: {
                getData: (type = pasteType) => pastePayload,
            },
        });
        $destination[0].dispatchEvent(pasteEvent);
    });
}

Cypress.Commands.add('paste', {
  prevSubject: true,
  element: true
}, ($element, text) => {
  const subString = text.substr(0, text.length - 1);
  const lastChar = text.slice(-1);

  $element.text(subString);
  $element.val(subString);
  cy.get($element.selector).type(lastChar);
});

Thank you @jamiljay , I really like your approach!

BTW at least in my case I had to change the last line to avoid conflicts with multiple candidate elements:

Cypress.Commands.add('paste', {
    prevSubject: true,
    element: true
}, ($element, text) => {

    const subString = text.substr(0, text.length - 1);
    const lastChar = text.slice(-1);

    $element.text(subString);
    $element.val(subString);
    cy.get($element).type(lastChar);
});

[navmed]

This mostly works for me, but the last line type(lastChar) clears the rest of the text and enters only the last character.

[Archinowsk]

I had to click the field first though it might be implementation specific.

Cypress.Commands.add(
  'paste',
  {
    prevSubject: true,
    element: true,
  },
  ($element, text) => {
    const subString = text.substr(0, text.length - 1);
    const lastChar = text.slice(-1);

    cy.get($element)
      .click()
      .then(() => {
        $element.text(subString);
        $element.val(subString);
        cy.get($element).type(lastChar);
      });
  }
);

Splicing substrings was giving me issues since I had "s in my input text. The following sets the text and value of the element to the given text, unmodified. Then cypress types a space followed by a backspace in order to properly trigger events.

/**
 * @param text: text to be pasted in
 */
// https://github.com/cypress-io/cypress/issues/1123#issuecomment-672640129
Cypress.Commands.add(
    "paste",
    {
        prevSubject: true,
        element: true
    },
    ($element, text) => {
        cy.get($element)
            .click()
            .then(() => {
                $element.text(text)
                $element.val(text)
                cy.get($element).type(" {backspace}")
            })
    }
)
