I would use Cheeriofor this.
我会为此使用Cheerio。
module.exports = {
"login": function (browser) {
var cheerio = require("cheerio")
browser
.url("http://www.wikipedia.org")
.waitForElementVisible('body', 1000)
.waitForElementVisible('select#searchLanguage', 1000)
.source(function(result) { // .source() dump the page source in the variable
$ = cheerio.load(result.value)
var num_languages = $('select#searchLanguage option').length
console.log('Wikipedia.org Languages: ' + num_languages);
})
.end();
}
};
or simply using the .execute()command
或者简单地使用.execute()命令

Just click the desired option.
只需单击所需的选项。
driver.findElement(webdriver.By.css('#mySelection > option:nth-child(4)'))
.click();
Note that I've changed your 'By' to a css selector. I'm lazy and like to just drill into the option from developer tools and select Copy CSS Path (chrome) or Copy Unique Selector (firefox).
请注意，我已将您的“By”更改为 css 选择器。我很懒，喜欢从开发人员工具中钻取选项并选择复制 CSS 路径 (chrome) 或复制唯一选择器 (firefox)。

You can create a function that select the value you desire
您可以创建一个函数来选择您想要的值
like this...
像这样...
driver.wait(
until.elementLocated(By.id("continents")), 20000
).then(element => {
selectByVisibleText(element, "Africa")
});
function selectByVisibleText(select, textDesired) {
select.findElements(By.tagName('option'))
.then(options => {
options.map(option => {
option.getText().then(text => {
if (text == textDesired)
option.click();
});
});
});
}

For anyone stuck on this, heres how I did it for a option:
对于任何坚持这一点的人，这是我如何做的一个选项：
<select id='mySelection'>
<option value='0'>Hello</option>
<option value='1'>Everybody</option>
<option value='2'>Got</option>
<option value='3'>It</option>
</select>
In Selenium for NodeJS, you would grab the "It" :
在用于 NodeJS 的 Selenium 中，您将获取 "It" ：
var webdriver = require('selenium-webdriver');
var driver = new webdriver.Builder().
withCapabilities(webdriver.Capabilities.chrome()).
build();
driver.findElement(webdriver.By.id('mySelection')).sendKeys('3');
When you .sendKeys() for the option it has to equal the value=''
当您为选项使用 .sendKeys() 时，它必须等于 value=''
In your case just grab the parent element then sendKeys() for the child element.
在您的情况下，只需获取父元素，然后为子元素使用 sendKeys() 即可。
