前言

有些网站是动态加载的，当拖动页面右侧滚动条后会自动加载网页下面的内容，或者通过鼠标滚轮操作。

鼠标滚轮操作

鼠标滚轮操作调用page.mouse.wheel() 方法

  • delta_x 横向移动距离
  • delta_y 纵向移动距离
def wheel(self, delta_x: float, delta_y: float) -> None:
    """Mouse.wheel

    Dispatches a `wheel` event.

    **NOTE** Wheel events may cause scrolling if they are not handled, and this method does not wait for the scrolling
    to finish before returning.

    Parameters
    ----------
    delta_x : float
        Pixels to scroll horizontally.
    delta_y : float
        Pixels to scroll vertically.
    """

使用示例

一边滚动一边加载网页

    page = browser.new_page()
    page.goto('http://events.jianshu.io/')

    for i in range(50):
        page.mouse.wheel(0, 100)
        page.wait_for_timeout(500)

    page.pause()
    browser.close()
