框架

简介​

一个Page可以附加一个或多个Frame对象。每个页面都有一个主框架，页面级别的交互（如click）默认在主框架中操作。

A page can have additional frames attached with the iframe HTML tag. These frames can be accessed for interactions inside the frame.

// Locate element inside frame
var username = await page.FrameLocator(".frame-class").GetByLabel("User Name");
await username.FillAsync("John");

Frame对象​

可以通过Page.Frame() API访问框架对象：

// Create a page.
var page = await context.NewPageAsync();

// Get frame using the frame's name attribute
var frame = page.Frame("frame-login");

// Get frame using frame's URL
var frame = page.FrameByUrl("*domain.");

// Get frame using any other selector
var frameElementHandle = await page.EvaluateAsync("window.frames[1]");
var frame = await frameElementHandle.ContentFrameAsync();

// Interact with the frame
await frame.FillAsync("#username-input", "John");
