class: Dialog
[Dialog] 对象通过 ‘dialog’ 事件的页面分发。
一个使用 Dialog 类的例子:
const puppeteer = require('puppeteer');puppeteer.launch().then(async browser => {const page = await browser.newPage();page.on('dialog', async dialog => {console.log(dialog.message());await dialog.dismiss();await browser.close();});page.evaluate(() => alert('1'));});
dialog.accept([promptText])
promptText<[string]> 提示中输入的文本。 如果对话框的类型不提示,不会产生任何影响。- returns: <[Promise]> Promise which resolves when the dialog has been accepted.
dialog.defaultValue()

dialog.dismiss()
- returns: <[Promise]> Promise which resolves when the dialog has been dismissed.
dialog.message()

dialog.type()
