You can try to use the following script to make element visible: document.getElementById('periodId').style.display='block';
您可以尝试使用以下脚本使元素可见： document.getElementById('periodId').style.display='block';
In java code this script can be executed with the following code:
在 java 代码中，可以使用以下代码执行此脚本：
JavascriptExecutor executor = (JavascriptExecutor)driver;
executor.executeScript("document.getElementById('periodId').style.display='block';");
If you just want to select an option in drop down you can use the following java code:
如果您只想在下拉列表中选择一个选项，您可以使用以下 java 代码：
Select select = new Select(driver.findElement(By.id("periodId")));
select.deselectAll();
select.selectByVisibleText("Last 4 Weeks");
