python-3.x - Selenium Python没有定位元素

问题描述

我有一个 Selenium python 代码，我在内部动态 CRM 网站上运行以下载数据。在大多数情况下，代码一直工作到最后一步，它没有找到元素“导出数据”。导出数据出现在我们上一步触发的工具栏上的新功能区中。下面是代码和HTML。还附上了导出的 HTML 部分。我究竟做错了什么？如果您需要更多信息，请帮助并告诉我

屏幕 1 CRM 在单击时显示结果按钮将我们带到屏幕 2，它是工具栏上的一个新选项卡： 相关图片 屏幕 2 带有工具栏上的新选项卡 相关图片 导出 HTML 代码 相关图片

解决方案

您可能只需要在代码中等待元素：

    web_results = browser.find_element_by_xpath('//*[@id="apttusps.ApplicationRibbon.{!EntityLogicalName}.Button2.Button-Large"]') 
web_results.click()


    element = WebDriverWait(driver, 10).until(
    EC.presence_of_element_located((By.ID, "apttus_apts_agreement|NoRelationship|SubGridStandard|Mscrm.SubGrid.apttus_apts_agreement.MainTab.ExportData"))
)

# ribbonframe = browser.find_element_by_id('apttus_apts_agreement|NoRelationship|SubGridStandard|Mscrm.SubGrid.apttus_apts_agreement.MainTab.ExportData')
