Selenium 单击<li> 中的href 中的链接. [英] Selenium to click a link in href which in &lt;li&gt;

问题描述

我想使用 selenium 点击?currentPage=3"；例如，在网站本身上，您单击的按钮会重定向到 href，但是当我使用 selenium 时，没有任何反应.我尝试了很多迭代，也查找了类似的指南，但都无济于事.

<div class="epub"><div class="column epub-nav"><div class="epub-nav-inner"><div class="epub-meta"><p>uid:978-9949-559-55-8</p><p>创建者:</p><p>发布者:</p><p>主题:</＞
<nav epub:type="toc";id=toc"><ol><li><a href="?currentPage=3">Tööraamatu kasutajale</a><li><a href=?currentPage=4">1.Arvuhulgad ja avaldised</a><li><a href="?currentPage=4">1.1.Arvuhulgad </a><li><a href="?currentPage=7">1.2.Tehted astmete ja juurtega </a><li><a href="?currentPage=11">1.3.Ratsionaalavaldise lihtsustamine </a >

解决方案

To Click() 你必须为 ElementToBeClickable() 并且您可以使用以下任一定位器策略:

• LinkText:

  new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.ElementToBeClickable(By.LinkText("Tööraamatu kasutajale"))).Click();

• CssSelector:

  new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.ElementToBeClickable(By.CssSelector("li > a[href='?currentPage=3']"))).点击();

• XPath:

  new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.ElementToBeClickable(By.XPath("//li/a[@href='?currentPage=3' and text()='Tööraamatu kasutajale']"))).Click();

更新

可能您需要 SeleniumExtras.WaitHelpers，您可以使用以下任一解决方案:

• LinkText:

  new WebDriverWait(driver, TimeSpan.FromSeconds(10)).Until(SeleniumExtras.WaitHelpers.ExpectedConditions.ElementToBeClickable(By.LinkText("Tööraamatu kasutajale"))).Click();

• CssSelector:

  new WebDriverWait(driver, TimeSpan.FromSeconds(10)).Until(SeleniumExtras.WaitHelpers.ExpectedConditions.ElementToBeClickable(By.CssSelector("li > a[href='?currentPage=3']";))).点​​击();

• XPath:

  new WebDriverWait(driver, TimeSpan.FromSeconds(10)).Until(SeleniumExtras.WaitHelpers.ExpectedConditions.ElementToBeClickable(By.XPath("//li/a[@href='?currentPage=3')和 text()='Tööraamatu kasutajale']"))).Click();

I want to use selenium to click on the "?currentPage=3" for example, on the website itself the button you click redirects to the href, however when I use selenium, nothing happens. I have tried so many iterations and also looked up similar guides, yet to no avail.

                    </li>
                                        <li>
                        <a href="?currentPage=4">1.1. Arvuhulgad</a>
                    </li>
                                        <li>
                        <a href="?currentPage=7">1.2. Tehted astmete ja juurtega</a>
                    </li>
                                        <li>
                        <a href="?currentPage=11">1.3. Ratsionaalavaldise lihtsustamine</a>
                    </li>

解决方案

To Click() on the element you have to induce WebDriverWait for the ElementToBeClickable() and you can use either of the following Locator Strategies:

• LinkText:

  new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.ElementToBeClickable(By.LinkText("Tööraamatu kasutajale"))).Click();
  

• CssSelector:

  new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.ElementToBeClickable(By.CssSelector("li > a[href='?currentPage=3']"))).Click();
  

• XPath:

  new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.ElementToBeClickable(By.XPath("//li/a[@href='?currentPage=3' and text()='Tööraamatu kasutajale']"))).Click();
