innerHTML在Firefox中运行良好,而当我在Chrome中尝试同样的方法时,它不起作用

 try 
     {
         String mouseOverScript = "if(document.createEvent){var evObj = document.createEvent('MouseEvents');evObj.initEvent('mouseover',true, false); arguments[0].dispatchEvent(evObj);} else if(document.createEventObject) { arguments[0].fireEvent('onmouseover');}";
         ((JavascriptExecutor) driver).executeScript(mouseOverScript,uploadFileInputFieldWebElement);
         Thread.sleep(1000);
         invalidLicenseFileTypeMessag = (String)((JavascriptExecutor)driver).executeScript("return arguments[0].innerHTML;",tooltipWebElement);


    } catch (Exception e) {
        exception message;

    }
