node.js - 错误消息: Unable to find element with xpath in phantomsJS

Question

我正在使用简单的 NodeJS 脚本来测试 google.com。使用phantomJS浏览器。

var webdriver = require('selenium-webdriver');
var assert = require('assert');

var driver = new webdriver.Builder().
withCapabilities({
    browserName : "phantomjs"
}).
usingServer('http://127.0.0.1:4444/wd/hub').build();

//driver.manage().timeouts().implicitlyWait(60000);

driver.get('http://www.google.com');
driver.findElement(webdriver.By.xpath('//*[@id="gbqf"]')).sendKeys('webdriver');
driver.findElement(webdriver.By.name('btnG')).click();
driver.getTitle().then(function(title) {
    assert.equal("webdriver - Google Search", title);
 });

driver.quit();

使用运行独立的 selenium 服务器

> java -jar selenium-server-standalone-2.35.0.jar

使用 node 命令并行运行脚本。

我收到以下错误

Answer 1

该页面是否有可能尚未完全加载，因为我知道当我访问 google.com 时，它会将我重定向到本地 google.co.uk 网站。

严格出于调试目的，请在 findElement 命令之前休眠 5 秒。如果有效，请替换为 webdriver，等待该对象出现在屏幕上。

但是，我也注意到您正在将 key 发送到“form”元素。这行得通吗？您不想将 key 发送到输入字段吗？
