Cypress mixes charCodes and keyCodes in `type()` function

Current behavior:

Reference to ASCII table: https://www.asciitable.com

Normall ASCII charcode of dot character . is 46:

But cypress with type() function uses charcode 190:

Using code bellow it doesn’t work too. Cypress just converts String.fromCharCode(46) to 190 and normal . is also 190.

Code:

cy.get('#dateField').type('3' + String.fromCharCode(48) + String.fromCharCode(46) + '12.2020', {delay: 100});

What it does:

And here is our problem: preventedDefault Our JS verifies input and it preventDefault by this RegExp: var regex = new RegExp("^[0-9.]+$");.

(snippet of) JS:

date: function (event) {
	if (event.charCode != 0) {
		var regex = new RegExp("^[0-9.]+$");
		var key = String.fromCharCode(!event.charCode ? event.which : event.charCode);
			if (!regex.test(key)) {
				event.preventDefault();
				return false;
			}
	}
}

Desired behavior:

Well… Cypress’ type() function should use right charcodes.

Steps to reproduce:

I already posted these steps above.

Versions

Cypress ['3.0.1', '3.0.2'] on ['macOS 10.13', 'macOS 10.14', 'Windows 10 1803', 'Ubuntu 18.04']

A workaround that fixed it for me was just to delete the key mapping from the cypress internals in the beforeEach method:

    beforeEach(() => {
        delete Cypress.Keyboard.charCodeMap[47]; // Delete the '/' key from the mapping so it works as expected
    });

This might break other stuff though…

Wow, well done cypress team! I literally just hit this issue and apparently it’s just been fixed! 👏
