推荐答案

Selenium无法点击您想要选择的元素被视为不可见（非活动）。所以唯一的方法（imho）使用js来解决这个问题。
这对我在java工作：

Selenium won't be able to click as element you want to select is considered to be invisible(inactive). So the only way(imho) to use js to resolve this issue. That worked for me in java:

 @Test
    public void neeededDropdownSelect() throws InterruptedException {
        driver.get("https://mbsdisclosure.fanniemae.com/PoolTalk2/index.html");
          jsClickOnElement("li#tab_1>a>span");
        WebElement dropdownMenu = fluentWait(By.cssSelector("span#asSelectedSecType"));
        dropdownMenu.click();


        jsClickOnElement("div[class=\"fg-menu-container ui-widget ui-widget-content ui-corner-all fg-menu-flyout\"] ul[class=\"fg-menu ui-corner-all\"]>li>a[id=\"MEGA_INTERIM\"]");
        jsClickOnElement("div[class=\"fg-menu-container ui-widget ui-widget-content ui-corner-all fg-menu-flyout\"] ul[class=\"fg-menu ui-corner-all\"]>li>ul.ui-corner-all a[id=\"MEGA_INTERIM_ARM\"]");

    }

  public WebElement fluentWait(final By locator){
        Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)
                .withTimeout(30, TimeUnit.SECONDS)
                .pollingEvery(5, TimeUnit.SECONDS)
                .ignoring(NoSuchElementException.class);

        WebElement foo = wait.until(
                new Function<WebDriver, WebElement>() {
                    public WebElement apply(WebDriver driver) {
                        return driver.findElement(locator);
                    }
                }
        );
        return  foo;              }     ;

    public void jsClickOnElement(String cssSel){
        JavascriptExecutor js = (JavascriptExecutor) driver;
        StringBuilder stringBuilder = new StringBuilder();
        stringBuilder.append("var x = $(\'"+cssSel+"\');");
        stringBuilder.append("x.click();");
        js.executeScript(stringBuilder.toString());

    }
