web自动化（5）----selenium运行JavaScript代码

selenium运行JavaScript

String JavaScriptString = ""；

JavascriptExecutor js = (JavascriptExecutor) driver;

js.executeScript(JavaScriptString, element);

模拟鼠标悬停在元素上

<span style="font-size:18px;">WebElement ele = dr.findElement(By.xpath("/html/body/div[1]/div[3]/div[2]/div[1]/div[3]/div/ul/li[3]"));// action.moveToElement(ele).perform();String mouseHoverjs = "var evObj = document.createEvent('MouseEvents');"+ "evObj.initMouseEvent(\"mouseover\",true, false, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null);"+ "arguments[0].dispatchEvent(evObj);";JavascriptExecutor js = (JavascriptExecutor) dr;js.executeScript(mouseHoverjs, ele);</span>

JS可以模拟各种鼠标操作、键盘操作，这方面需要进一步学习。很强大的一个功能
