web自動化（5）----selenium運行JavaScript代碼

selenium運行JavaScript

String JavaScriptString = ""；

JavascriptExecutor js = (JavascriptExecutor) driver;

js.executeScript(JavaScriptString, element);

模擬鼠標懸停在元素上

<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可以模擬各種鼠標操作、鍵盤操作，這方面需要進一步學習。很強大的一個功能
