問題描述
我想點(diǎn)擊這個(gè)頁面的打印按鈕:
，還是有希望的，你會(huì)看到有相關(guān)的:
<塊引用>--disable-print-preview - 禁用打印預(yù)覽(用于測試和不喜歡我們的用戶.:[)
好的，我們試試看:
ChromeOptions 選項(xiàng) = new ChromeOptions();options.addArguments("--disable-print-preview");WebDriver driver = new ChromeDriver(options);driver.get(url);現(xiàn)在，顯示了一個(gè)系統(tǒng)打印對話框:
Selenium 也無法控制它.所以，不，沒有希望.哦，等等！
<小時(shí)>好的，如果我們超出了 selenium 的范圍，讓我們使用可以幫助我們單擊對話框中的 Print 按鈕的工具 - Robot 類:
該類用于為測試自動(dòng)化、自運(yùn)行演示和其他目的需要控制鼠標(biāo)和鍵盤的應(yīng)用程序.
我們將初始化 Robot 并在打印對話框出現(xiàn)時(shí)發(fā)送 Enter 鍵:
包c(diǎn)om.company；導(dǎo)入 org.openqa.selenium.By；導(dǎo)入 org.openqa.selenium.WebDriver；導(dǎo)入 org.openqa.selenium.WebElement；導(dǎo)入 org.openqa.selenium.chrome.ChromeDriver；導(dǎo)入 org.openqa.selenium.support.ui.ExpectedConditions；導(dǎo)入 org.openqa.selenium.support.ui.WebDriverWait；導(dǎo)入 java.awt.*；導(dǎo)入 java.awt.event.KeyEvent；公共類主要{public static void main(String[] args) 拋出 AWTException，InterruptedException {字符串 url = "https://www.google.com/maps/dir/40.4515849,-3.6903752/41.380896,2.1228198/@40.4515849,-3.6903752/am=t/?hl=en";機(jī)器人 r = new Robot();r.延遲(1000)；WebDriver driver = new ChromeDriver();driver.get(url);//打開打印下拉菜單WebDriverWait 等待 = new WebDriverWait(驅(qū)動(dòng)程序, 10);wait.until(ExpectedConditions.elementToBeClickable(By.cssSelector("button.print-button"))).click();//點(diǎn)擊打印按鈕WebElement printButton = driver.findElement(By.cssSelector("button.print-popup-button"));printButton.click();線程.sleep(2000);r.keyPress(KeyEvent.VK_ENTER);r.keyRelease(KeyEvent.VK_ENTER);}}使用其他選項(xiàng):

I want to click on the print button in this page :
https://www.google.com/maps/dir/40.4515849,-3.6903752/41.380896,2.1228198/@40.4515849,-3.6903752/am=t/?hl=en
and then save the PDF...
this is the code for click the button:
String url = "https://www.google.com/maps/dir/40.4515849,-3.6903752/41.380896,2.1228198/@40.4515849,-3.6903752/am=t/?hl=en";
WebDriver driver = new HtmlUnitDriver();
driver.get(url);
System.out.println(driver.getTitle());
System.out.println(driver.getCurrentUrl());
WebElement element = driver.findElement(By.xpath("http://*[@id="text-mode-options-header"]/div/div/div[2]/div[2]/div/button[1]"));
element.click();
System.out.println("Page title is: " + driver.getTitle());
driver.quit();
but I get the following error:
Exception in thread "main" org.openqa.selenium.NoSuchElementException: Unable to locate a node using //*[@id="text-mode-options-header"]/div/div/div[2]/div[2]/div/button[1]

how can I do this using Selenium? is there another way? thanks.
EDIT:
Here's my insight.
First of all, you need to wait for the page to load in order to interact with the Print button. The best way to go is to use built-in mechanism: selenium waits - wait for the Print button to be clickable:
// open print dropdown
WebDriverWait wait = new WebDriverWait(driver, 10);
wait.until(ExpectedConditions.elementToBeClickable(By.cssSelector("button.print-button"))).click();
// click print button
WebElement printButton = driver.findElement(By.cssSelector("button.print-popup-button"));
printButton.click();
Okay, if you run it using ChromeDriver:
package com.company;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
public class Main {
public static void main(String[] args) {
String url = "https://www.google.com/maps/dir/40.4515849,-3.6903752/41.380896,2.1228198/@40.4515849,-3.6903752/am=t/?hl=en";
WebDriver driver = new ChromeDriver();
driver.get(url);
// open print dropdown
WebDriverWait wait = new WebDriverWait(driver, 10);
wait.until(ExpectedConditions.elementToBeClickable(By.cssSelector("button.print-button"))).click();
// click print button
WebElement printButton = driver.findElement(By.cssSelector("button.print-popup-button"));
printButton.click();
// now what?
}
}
You'll see the Chrome Print Preview dialog, which is, unfortunately, out of scope for selenium:
But, there is a hope, if you examine available Chrome arguments, you would see that there is the relevant one:
--disable-print-preview - Disables print preview (For testing, and for users who don't like us. :[ )
Okay, let's try it out:
ChromeOptions options = new ChromeOptions();
options.addArguments("--disable-print-preview");
WebDriver driver = new ChromeDriver(options);
driver.get(url);
Now, there is a system print dialog being shown:
Selenium cannot control it too. So, nope, there is no hope. Oh, wait!
Okay, if we are out of scope of selenium, let's use tools that can help us to click that Print button in the dialog - Robot class:
This class is used to generate native system input events for the purposes of test automation, self-running demos, and other applications where control of the mouse and keyboard is needed.
We'll initialize the Robot and will send Enter key when the print dialog would show up:
package com.company;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import java.awt.*;
import java.awt.event.KeyEvent;
public class Main {
public static void main(String[] args) throws AWTException, InterruptedException {
String url = "https://www.google.com/maps/dir/40.4515849,-3.6903752/41.380896,2.1228198/@40.4515849,-3.6903752/am=t/?hl=en";
Robot r = new Robot();
r.delay(1000);
WebDriver driver = new ChromeDriver();
driver.get(url);
// open print dropdown
WebDriverWait wait = new WebDriverWait(driver, 10);
wait.until(ExpectedConditions.elementToBeClickable(By.cssSelector("button.print-button"))).click();
// click print button
WebElement printButton = driver.findElement(By.cssSelector("button.print-popup-button"));
printButton.click();
Thread.sleep(2000);
r.keyPress(KeyEvent.VK_ENTER);
r.keyRelease(KeyEvent.VK_ENTER);
}
}
Other options are to use:
sikuli- you would need an image of the print button in order for sikuli to locate it and clickautoit
