【问题描述】：

来自本网站：https://etherscan.io/address/0x6eed5b7ec85a802428f7a951d6cc1523181c776a#writeContract。 1.程序首先点击“连接网络”。 2.然后我想点击“Wallet Connect”.

目前，只有在删除 driver.execute_script('''window.open("http://bings.com","_blank");''') 时，Wallet Connect 才会点击。 driver.switch_to.window(driver.window_handles[0]) 只有在只有一个选项卡时才会切换到包含钱包的弹出窗口。当有另一个选项卡（或任意数量的选项卡）时，如何切换到弹出窗口；即当driver.execute_script('''window.open("http://bings.com","_blank");''') 包含在脚本中时。

【问题讨论】：

它只输出2个句柄，每个选项卡一个，没有弹出句柄
弹出窗口也不在 iframe 中。

【解决方案1】：

wait=WebDriverWait(driver,10)
driver.get("https://etherscan.io/address/0x6eed5b7ec85a802428f7a951d6cc1523181c776a#writeContract")
driver.execute_script('''window.open("http://bings.com","_blank");''')#code works only if this is removed

driver.switch_to.window(driver.window_handles[0])
wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button#btnCookie"))).click()
wait.until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe#writecontractiframe")))
elem=wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button#connectStatus")))
driver.execute_script("arguments[0].click();", elem)
driver.switch_to.default_content

##wait.until(EC.number_of_windows_to_be(1))
driver.switch_to.window(driver.window_handles[0])
wait.until(EC.element_to_be_clickable((By.XPATH, """//button[@onclick="connectWalletConnect('writecontractiframe')"]"""))).click()

您从来没有真正关闭窗口，因为窗口数量为 1。而且你从来没有离开过 iframe。
