与IFrames和frames一起工作

框架是一种现在已被弃用的方法，用于从同一域中的多个文档构建站点布局。除非你使用的是 HTML5 之前的 webapp，否则你不太可能与他们合作。内嵌框架允许插入来自完全不同领域的文档，并且仍然经常使用。

如果您需要使用框架或 iframe, WebDriver 允许您以相同的方式使用它们。考虑 iframe 中的一个按钮。 如果我们使用浏览器开发工具检查元素，我们可能会看到以下内容:

<div id="modal">
  <iframe id="buttonframe"name="myframe"src="https://seleniumhq.github.io">
   <button>Click here</button>
 </iframe>
</div>

如果不是 iframe，我们可能会使用如下方式点击按钮:

// 这不会工作
driver.findElement(By.tagName("button")).click();
    # 这不会工作
driver.find_element(By.TAG_NAME, 'button').click()
// 这不会工作
driver.FindElement(By.TagName("button")).Click();
    # 这不会工作
driver.find_element(:tag_name,'button').click
// 这不会工作
await driver.findElement(By.css('button')).click();
// 这不会工作
driver.findElement(By.tagName("button")).click()

但是，如果 iframe 之外没有按钮，那么您可能会得到一个 no such element 无此元素 的错误。 这是因为 Selenium 只知道顶层文档中的元素。为了与按钮进行交互，我们需要首先切换到框架， 这与切换窗口的方式类似。WebDriver 提供了三种切换到帧的方法。

使用 WebElement

使用 WebElement 进行切换是最灵活的选择。您可以使用首选的选择器找到框架并切换到它。

         //switch To IFrame using Web Element
         WebElement iframe = driver.findElement(By.id("iframe1"));
         //Switch to the frame
         driver.switchTo().frame(iframe);
         assertEquals(true, driver.getPageSource().contains("We Leave From Here"));
         //Now we can type text into email field
         WebElement emailE = driver.findElement(By.id("email"));
         emailE.sendKeys("admin@selenium.dev");
         emailE.clear();
