量角器：sendKeys 不适用于 type="number"

Question

I'm trying to send numeric input using sendKeys but it isn't working. This is my HTML:

<input type="number" maxlength="3950">

And this is how I'm trying to locate the input box and add a number to it:

var input = element(by.css('input'));
input.clear();
browser.sleep(5000);
input.sendKeys('2'); //Here's the error
browser.sleep(1000);
var btn = element(by.css(".btn.btn-action.btn-ok" ));

And this is the error:

Failed: No element found using locator: By(css selector, .btn.btn-action.btn-ok)

Answer 1

First off all post the error you are getting, secondly it looks obvious that you are using a very generic selector and you may have more than one input on a given page. Try something unique like,

var input = element(by.css('input[type='number']'));
input.clear();
input.sendKeys('2');
