WebElementelement=driver.findElement(By.id("myElement")); 1. 如果findElement方法找不到指定的元素,它会抛出NoSuchElementException异常。这就是为什么当选择器指定的元素不存在时,程序会卡住的原因。 解决方案 为了避免程序卡住,可以使用findElements方法代替findElement方法。findElements方法与findElement方法类似,但是...
// An array storing different ages int ages[] = {20, 22, 18, 35, 48, 26, 87, 70}; // Create a 'lowest age' variable and assign the first array element of ages to it int lowestAge = ages[0]; // Loop through the elements of the ages array to find the lowest age for (int...
Finally We use getAsInt() to access the first matching element. In this array, we get the value 25 (as it is greater than or equal to 20). import java.util.Arrays; import java.util.OptionalInt; import java.util.stream.IntStream; public class Program { public static void main(String[...
我们可以先定位其父元素,然后定位其子元素,方法如下: WebElement father = driver.findElement(By.id("father")); WebElement son = father.findElement(By.linkText("xxx")); 也可以将他们缩写成一行: 1 WebElement son = driver.findElement(By.id("father")).findElement(BylinkText("xxx")); 4. NoSu...

如果在使用 IntelliJ IDEA 编写 Java 程序时出现“can't find filter element”的错误提示，可以尝试以下方法解决：检查代码是否存在编译错误。可以在编辑器中使用快捷键Ctrl + Alt + L格式化代码，并检查是否存在编译错误。检查依赖的包是否正确导入。如果使用了第三方库，需要确保在程序中正确导入了相应的...
