Python和Selenium-在离开页面时禁用警报

卸载前禁用警报 :

def super_get(url):
    driver.get(url)
    driver.execute_script("window.onbeforeunload = function() {};")

现在使用 super_get(whatever_url) driver.get(whatever_url)

禁用页面中的所有警报

def super_get(url):
    driver.get(url)
    driver.execute_script("window.alert = function() {};")

球门 通过getEventListeners(window)['beforeunload']获取所有侦听器,并将其全部删除。

步骤1。放入DOMDebugger。getEventListeners到窗口['getEventListeners']

Dim myChromeDriver as ChromeDriver = getMyDriver()
myChromeDriver.ExecuteChromeCommand("Runtime.evaluate", New Dictionary(Of String, Object)() From {
{"expression", "window['getEventListeners'] = getEventListeners;"},
{"includeCommandLineAPI", True}})

我们不需要这个命令的结果值。

includeCommandLineAPI=True是必需的,否则它将引发异常,因为getEventListeners是脚本执行上下文中未定义的CommandLineAPI

步骤2.删除所有侦听器

Dim jsCmd As String = "var eventlistener = window['getEventListeners'](window)['beforeunload'][0];" &
"    window.removeEventListener('beforeunload', " &
"    eventlistener.listener, " &
"    eventlistener.useCapture); "
myChromeDriver.ExecuteScript(jsCmd)

当删除所有侦听器时,此脚本将引发异常,您可以修复它。
