Question

我正在尝试在nodejs中获取网页标题，并且以下代码可以正常工作。我可以通过console.log（“标题为-” + webpagetitle）

var afterLoad=require('after-load');

var webdriver = require('selenium-webdriver'),
	By = webdriver.By,
	until = webdriver.until;

var chrome = require('selenium-webdriver/chrome');

var options = new chrome.Options();
options.addArguments("-headless");

var driver = new webdriver.Builder()
	.forBrowser('chrome')
	.setFirefoxOptions(options)
	.build();

	
	driver.get('https://www.google.com/').then(function()
	{
	driver.getTitle().then(function (webpagetitle) {
			 console.log("Title is - "+webpagetitle);
			 }
	)});

但是，当尝试使用如下所示的afterLoad时，则无法正常工作。

var afterLoad=require('after-load');

var webdriver = require('selenium-webdriver'),
	By = webdriver.By,
	until = webdriver.until;

var chrome = require('selenium-webdriver/chrome');

var options = new chrome.Options();
options.addArguments("-headless");

var driver = new webdriver.Builder()
	.forBrowser('chrome')
	.setFirefoxOptions(options)
	.build();

			
	
	afterLoad('https://www.google.com/', function (){
			driver.getTitle().then(function (webpagetitle) {
			 console.log("Title is - "+webpagetitle);
			 }
			 )}
			 );

错误- 打开空白页面，并且在控制台中标题为空白，见下文：

Answer 1

 afterLoad('https://google.com',function(html){
        browser.getTitle().then(function (webpagetitle) {
           console.log("Heyyyyyy title is - "+webpagetitle);
        })
 })

不需要function关键字，因为afterLoad包中已经声明了after-load函数，因此您只需调用它即可。用法示例here

无法通过AfterLoad函数传递网址
