Java:无效选择器:指定了无效或非法的选择器

Question

我正在尝试点击付款弹出窗口中的一个元素:

<label data-v-533987c6="" xpath="1">Card Number:</label>
<input data-v-533987c6="" type="tel" data-mask="#### #### #### ####" data-previous-value="" xpath="1">

具有以下 xPath:

@FindBy(name = "//div[contains(@class,'买票')]//div/label[text()='卡号:']/following-sibling::input")

但我收到此错误:

org.openqa.selenium.InvalidSelectorException: invalid selector: An invalid or illegal selector was specified

*** Element info: {Using=name, value=//div[contains(@class,'buy-tickets')]//div/label[text()='Card Number:']/following-sibling::input}

为什么？希望你能帮助我!

Answer 1

根据错误信息

Element info: {Using=name, value=//div[contains(@class,'buy-tickets')]//div/label[text()='Card Number:']/following-sibling::input}

您正在尝试使用另一个xpath

//div[contains(@class,'buy-tickets')]//div/label[text()='Card Number:']/following-sibling::input`

与By.name，这是无效的。您需要使用By.xpath。
