java+selenium——详解介绍Selenium常用API的使用--Java语言（完整版）

=================================================================================================================================================

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())

driver.findElement(By.xpath())

driver.findElement(By.cssSelector())

定位一组元素：

driver.findElements(By.id())

driver.findElements(By.name())

driver.findElements(By.className())

driver.findElements(By.tagName())

driver.findElements(By.linkText())

driver.findElements(By.partialLinkText())

driver.findElements(By.xpath())

driver.findElements(By.cssSelector())

==========================================================================================================================================

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

System.out.println(title); //打印的是当前浏览器的title值

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

操作浏览器的cookie：

driver.manage().getCookies(); //获取当前页面下所有cookies

driver.manage().deleteAllCookies(); //删除所有cookies

driver.manage().deleteCookieNamed("cookie的某个key值"); //删除某个指定的cookie
