如何构建一种方法来遍历WebElements并返回使用Selenium和Java显示的方法？

因此，页面充满了很多类似的属性，例如下面的两个元素。例子：

<button id="exibe_codigo_de_barras_210888-1" data-context="minhas-contas_conta_codigo-barras_btn-ver-codigo-barras-colapse" font-size="0.875rem" width="100%"xpath="1">VER CÓDIGO DE BARRAS <span><svg width="12px" height="8px" viewBox="0 0 12 8" version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"><defs><polygon id="chevron" points="7.41 8 12 12.9446694 16.59 8 18 9.52226721 12 16 6 9.52226721"></polygon></defs><g id="Symbols" stroke="none" stroke-width="1" fill="none" fill-rule="evenodd"><g id="Interface/Seta-expandir" transform="translate(-6.000000, -8.000000)"><mask id="mask-2" fill="white"><use xlink:href="#chevron"></use></mask><use id="Seta-expandir" fill="#D82482" fill-rule="nonzero" xlink:href="#chevron"></use></g></g></svg></span></button>
<button id="exibe_codigo_de_barras_210888-2" data-context="minhas-contas_conta_codigo-barras_btn-ver-codigo-barras-colapse" font-size="0.875rem" width="100%"xpath="1">VER CÓDIGO DE BARRAS <span><svg width="12px" height="8px" viewBox="0 0 12 8" version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"><defs><polygon id="chevron" points="7.41 8 12 12.9446694 16.59 8 18 9.52226721 12 16 6 9.52226721"></polygon></defs><g id="Symbols" stroke="none" stroke-width="1" fill="none" fill-rule="evenodd"><g id="Interface/Seta-expandir" transform="translate(-6.000000, -8.000000)"><mask id="mask-2" fill="white"><use xlink:href="#chevron"></use></mask><use id="Seta-expandir" fill="#D82482" fill-rule="nonzero" xlink:href="#chevron"></use></g></g></svg></span></button>

我正在使用PageObject和PageFactory来获取元素，并将它们放入这样的数组中：

@FindAll(@FindBy(how = How.CSS, using = "[data-context=minhas-contas_conta_codigo-barras_btn-ver-codigo-barras-colapse]"))public List<WebElement> btnVerCodigoDeBarras;

问题是这样的：我需要单击这些类似的按钮之一，而不使用索引（ 因为事实证明，要维护它很麻烦
）。我想到了一种方法，我可以收集列表中的所有webElement并返回显示在屏幕上的单个webElement（我乐于接受新想法），所以这是我尝试的两种方法，但均未成功：

public static WebElement WaitForElementVisibleInArray(List<WebElement> elements) {    boolean arrayNotEmpty = elements.size() > 0;    if (arrayNotEmpty) {        for (Iterator<WebElement> i = elements.iterator(); i.hasNext(); ) {            WebElement element = i.next();            if (element.isEnabled() && element.isDisplayed()) {                return element;            }        }    }    return null;}
public static WebElement WaitForElementVisibleInArray(List<WebElement> elements) {    boolean arrayNotEmpty = elements.size() > 0;            if (arrayNotEmpty) {                    Iterator<WebElement> it = elements.iterator();        WebElement element;        while (it.hasNext()) {            element = it.next();            if (element.isEnabled() && element.isDisplayed()) {                return element;            }        }    }    return null;}

我进行了很多搜索，无法解决这个问题。先感谢您！

小编典典

我将展示如何解决这个问题，但是问题可能出在硒元素不总是根据元素类型正确返回isDisplayed（）的问题上。

public WebElement getFirstVisibleElement(List<WebELement> elements) {    for (WebElement ele : elements)        if (ele.isEnabled() && ele.isDisplayed())            return ele;    return null;}

检查是否显示Web元素的一种更可靠的方法是检查其尺寸（高度和宽度）。如果它们均为零，则不显示。

public WebElement getFirstVisibleElement(List<WebELement> elements) {    for (WebElement ele : elements)        if (ele.isEnabled() && ele.getSize().getHeight() > 0 && ele.getSize().getWidth() > 0 )            return ele;    return null;}

Java Selenium，如何从链接WebElement获取linkText（锚）

Java Selenium，如何从链接WebElement获取linkText（锚）

如何解决Java Selenium，如何从链接WebElement获取linkText（锚）？

试试这个：

System.out.println(link.getText());

解决方法

我有一个包含由url找到的链接的WebElement。我可以通过以下方式提取网址：

element.getAttribute("href");

但是问题是：如何提取它的锚点，我正在尝试这样：

webElement.getAttribute("linkText");

它给了我空值。我100％确信此链接具有锚点。有什么办法获得锚点吗？它更加复杂，但是示例简化的代码可能如下所示：

WebDriver driver = new FirefoxDriver();
        driver.get("http://stackoverflow.com/questions/tagged/java");
        WebElement link  = driver.findElement(By.linkText("Bicycles"));

        System.out.println(link.getAttribute("href")); // shows http://bicycles.stackexchange.com/
        System.out.println(link.getAttribute("linkText")); // shows null

java – WebElement或WebDriver调用findElement方法？

java – WebElement或WebDriver调用findElement方法？

如果我们使用WebElement或WebDriver调用findElement方法有什么区别？他们每个人都有优势吗？提前致谢.

解决方法

WebElement和WebDriver之间的findElement的区别在于上下文.

WebDriver的上下文是当前页面,而WebElement的上下文就是该元素. WebDriver将搜索整个文档,而WebElement将尝试从该节点中查找第一个子元素.

请注意,通过XPath使用WebElement进行搜索时,从//开始仍将搜索整个文档,而不仅仅是当前节点的子项.您可以使用.//将搜索结果限制为该WebElement的子项.
