我打印时为什么要让父窗口处理程序和子窗​​口处理程序相同？

Question

String parentWindowHandler = browser.getWindowHandle(); // Store your parent window
System.out.println(parentWindowHandler);

browser.findElement(By.cssSelector("button.btn-danger")).click();
String subWindowHandler = null;

Set<String> handles = browser.getWindowHandles(); // get all window handles
Iterator<String> iterator = handles.iterator();
while (iterator.hasNext()){
    subWindowHandler = iterator.next();
}
browser.switchTo().window(subWindowHandler);
System.out.println(subWindowHandler);// switch to popup window

Answer 1

集合顶部的迭代器。当您到iterator.next()时，它将只是您的父窗口。如果您想要获取子窗口句柄，请执行更多iterator.next()

while (iterator.hasNext()){
parentWindowHandler = iterator.next();
subWindowHandler = iterator.next();

}
