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...

Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e.,0 1 2 4 5 6 7might become4 5 6 7 0 1 2). Find the minimum element. You may assume no duplicate exists in the array. 二、分析 这题难度有,因为他默认的是数组中所有的元素是不同的。只有分为两种情况...
findElement: 1. By id 使用id,name,class属性是定位元素的首选方法。其中,用元素的id是最首选的方法,是最快速的策略。 当发生下列情况时,无法使用id属性: 不是所有的页面元素都拥有id属性 id属性的值是动态生成的 2. findElement()方法定位元素时,会查询整个DOM,然后返回第一个匹配的元素 ...
