在量角器中模拟慢打字 [英] Simulate slow typing in Protractor

问题描述

sendKeys() 方法将一次发送所有密钥(实际上，一次发送一个，但速度非常快):

sendKeys() method would send all the keys at once (actually, one at a time but very quickly):

var elm = element(by.id("myinput"));
elm.sendKeys("test");

有没有办法减慢打字速度，以便量角器每次发送一个字符，每个字符之间有一个小的延迟?

Is there a way to slow the typing down so that Protractor would send one character at a time with a small delay between each of the characters?

我们可以完全减慢量角器的速度，但这不会改变 sendKeys() 的工作方式，它也会减慢一切，而我们只需要发送密钥"部分，并且只在特定情况下.

We can slow down Protractor entirely, but that does not change the way sendKeys() works and it would also slow everything down while we just need the "send keys" part and only in specific cases.

推荐答案

想法是使用 browser.actions() 并构造一系列发送密钥"命令 - 一个字符串中的每个字符.在每个发送密钥"命令之后，我们通过引入一个自定义sleep动作.最后，这是我们提出的可重用函数:

The idea is to use browser.actions() and construct a series of "send keys" command - one for every character in a string. After every "send keys" command we are adding a delay by introducing a custom sleep action. At the end, here is a reusable function we've come up with:

function slowType(elm, keys, delay) {
    var action = browser.actions().mouseMove(elm).click();

    for (var i = 0; i < keys.length; i++) {
        action = action.sendKeys(keys[i]).sleep(delay);
    }

    return action.perform();
}

用法:

slowType(elm, "some text", 100);
