driver.findElementById("kw")
……
引入包：import org.openqa.selenium.By;
driver.findElement(By.id())
driver.findElement(By.name())
driver.findElement(By.className())
driver.findElement(By.tagName())
driver.findElement(By.linkText())
driver.findElement(By.partialLinkText())

Eclipse中通过对象名.方法名即可调出所有Web Element的方法:参考网址：https://blog.csdn.net/woiangaoiowe/article/details/99285868
WebElement element = driver.findElement(By.id("kw"));
clear()：void——如果元素是一个文本类型的元素，则我们可以通过该方法来清空文本内容。语法：element.clrea();
sendkeys():void——向元素中填入值
click()：void——这个方法模拟用户在UI页面上点击元素的动作
isDisplayed():Boolean——该方法用来判断页面上该元素当前是否显示
isEnabled():boolean——用来判断界面元素是否是可用的，返回值为boolean值。返回boolean值，则可以考虑结合判断语句一起使用
isSelected():boolean——通过该方法来判断界面上的某个元素是否是选中状态
submit():boolean——通过该方法用来提交form表单。html中我们学习到form表单是通过submit方法来提交的，所以针对form元素，selenium也同样提供了我们submit这种提交数据的方法。
gettext():String——获取元素的文本内容。什么是文本内容？就是html尖括号对中间所写的文字
getTagName():String——tagname即html标签的标签类型，比如a、input、table等。
getCssValue():String——获取元素的css样式的值，入参string类型为元素内某个样式名称，比如背景色、长、宽等
getAttribute():String——获取元素内属性的值，入参内容为元素的某个属性名称
getLocation():Point——获取元素在页面上的坐标位置
