纯js移除元素 selenium

# class
JavascriptExecutor js_gold = (JavascriptExecutor) dr;
String js = "var elem = document.getElementsByClassName('mui-mbar-default')[0];"
                + "elem.parentNode.removeChild(elem);  ";
js_gold.executeScript(js);

如上，这里是selenium的用法

# id
String js2 = "var elem2 = document.getElementById('QunarPopBoxBG');"
                    + "elem2.parentNode.removeChild(elem2);  ";
js_gold.executeScript(js2);
