从optgroup中选择选项

Question

我正在尝试使用以下代码从optgroup中选择一个选项：

currency = Select(driver.find_element_by_xpath("//*[contains(text(), 'currencySelection_dropdown')]"))
currency.select_by_visible_text("U.S. Dollar (USD)")

但我有以下例外：

selenium.common.exceptions.UnexpectedTagNameException: Message: Select only works on <select> elements, not on <script>

我试图从中选择的下拉列表的html源是：

<select name="ppw-0h_PU_CUS_3cf45326-7ff2-49d1-b8a6-7834ec737a68_currencySelection_dropdown" autocomplete="off" id="pmts-portal-bbb6ae6f-f79e-4a31-bc4a-7128cea6c9c9" tabindex="0"

有什么帮助吗？我怎样才能解决这个问题

Answer 1

使用xpath尝试以下WebElement：

        WebElement element = driver.findElement(By.xpath("//select[@id=\"pmts-portal-bbb6ae6f-f79e-4a31-bc4a-7128cea6c9c9\"]"));
        element.click();
        Select selectCardCurrency = new Select(element);
        selectCardCurrency.selectByVisibleText("U.S. Dollar (USD)");

Answer 2

currency = Select(driver.find_element_by_xpath("//select[contains(@name, 'currencySelection_dropdown')]"))

您的主要问题是select标记和name标记的不规范

Answer 3

xpath应该对class属性执行contains()，而不是text()。text()函数返回元素的内部文本。此外，指定标记名而不是*：

currency = Select(driver.find_element_by_xpath("//select[contains(@class, 'currencySelection_dropdown')]"))
