前言

我们使用selenium进行元素拖拽时，通常要使用ActionChains来实现drag_and_drop的操作，playwright同样可以实现元素的拖拽和释放的操作。

按住元素从页面的一个位置拖动到另外一个位置，有2种方式可以实现

locator.drag_to(target: locator) 先定位元素，调用drag_to方法到目标元素page.drag_and_drop(source: str, target: str) page对象直接调用示例场景

我们以这个网页为例，介绍playwright的元素拖拽和释放的操作，网页地址：https://sahitest.com/demo/dragDropMooTools.htm，页面如下：

拖拽操作

locator.drag_to()可以实现拖放操作，该操作将：

将鼠标悬停在要拖动的元素上按鼠标左键将鼠标移动到将接收放置的元素松开鼠标左键

语法示例：

page.locator("#item-to-be-dragged").drag_to(page.locator("#item-to-drop-at"))

示例如下：

from playwright.sync_api import Playwright, sync_playwright, expect def run(playwright: Playwright) -> None: browser = playwright.chromium.launch(headless=False) context = browser.new_context() page = context.new_page() page.goto("https://sahitest.com/demo/dragDropMooTools.htm") page.locator("#dragger").drag_to(page.locator("text=Item 1")) page.pause() context.close() browser.close() with sync_playwright() as playwright: run(playwright) 拖动和释放操作

page.drag_and_drop可以实现通过page对象调用drag_and_drop ,部分源码如下：

def drag_and_drop( self, source: str, target: str, *, source_position: typing.Optional[Position] = None, target_position: typing.Optional[Position] = None, force: typing.Optional[bool] = None, no_wait_after: typing.Optional[bool] = None, timeout: typing.Optional[float] = None, strict: typing.Optional[bool] = None, trial: typing.Optional[bool] = None ) -> None:

注：source 和 target 是字符串格式，也就是传selector 选择器的方法

语法如下：

page.drag_and_drop(locator, loacator) from playwright.sync_api import Playwright, sync_playwright, expect def run(playwright: Playwright) -> None: browser = playwright.chromium.launch(headless=False) context = browser.new_context() page = context.new_page() page.goto("https://sahitest.com/demo/dragDropMooTools.htm") page.drag_and_drop('#dragger', 'text=Item 2') page.pause() context.close() browser.close() with sync_playwright() as playwright: run(playwright)

运行脚本，结果如下图：

鼠标拖动

想精确控制拖动操作，可以使用较低级别的方法，如locator.hover()、mouse.down()、mouse.move()和mouse.up()。代码如下：

from playwright.sync_api import Playwright, sync_playwright, expect def run(playwright: Playwright) -> None: browser = playwright.chromium.launch(headless=False) context = browser.new_context() page = context.new_page() page.get_by_text('Drag me').hover() page.mouse.down() page.locator('text=Item 3').hover() page.mouse.up() page.pause() context.close() browser.close() with sync_playwright() as playwright: run(playwright)

运行脚本，界面如下所示：

总结

本文主要介绍了playwright的元素拖拽和释放操作，与selenium一样，playwright同样支持元素拖拽操作，不过playwright的拖拽操作比selenium更加简单。
