java - Selenium getAttribute(href) 使用 java 返回 null 值 - Salesforce 应用程序

Question

这是 salesforce 应用程序。我想从 <a> 获取以下属性值标签

1. 引用

2. 标题

HTML 代码

<one-app-nav-bar-item-root one-appnavbar_appnavbar="" data-id="home" data-assistive-id="operationId" aria-hidden="false" draggable="true" class="navItem slds-context-bar__item slds-shrink-none slds-is-active" role="listitem" xpath="1">
<a href="/lightning/page/home" title="Home" tabindex="0" draggable="false" aria-describedby="operationId-14" class="slds-context-bar__label-action dndItem" style="">
<span class="slds-truncate">Home</span>
</a></one-app-nav-bar-item-root>

Selenium 代码(groovy 脚本语言)

for(int i:(1..size)){
            WebElement getHref = driver.findElement(By.xpath("//one-app-nav-bar-item-root[${i}]//a[1]"))
            println getHref.getAttribute("href")
            println getHref.getAttribute("title")
}

输出

null
null

注意:当我在 FireFox 中执行上述代码时，我得到了预期的结果

要提取 href 和 title 属性的值，您必须为 visibilityOfElementLocated() 引入 WebDriverWait或 elementToBeClickable() 并且您可以使用以下 Locator Strategies :

• xpath:

  • href:

    System.out.println(new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//one-app-nav-bar-item-root/a[//span[text()='Home']]"))).getAttribute("href"));
    

  • 标题:

    System.out.println(new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//one-app-nav-bar-item-root/a[//span[text()='Home']]"))).getAttribute("title"));
