html - 通过 VBA 使用 QuerySelector 单击 HTML 元素
问题描述
我正在尝试使用 VBA 自动访问网页。我正在通过登录屏幕，但我无法单击其中一个元素进入搜索屏幕。通常这并不太难，但似乎这个元素在 iframe 中？我不确定这是否是我看不到它的原因。我试图循环所有 A 标签并获得 nop 返回。我尝试使用查询选择器来访问它，我过去曾展示过它并工作过。两者都无济于事。我尝试了 4 种不同的方法来获取标签，想法是在匹配某些属性并单击之后执行 ForEach 循环：
Set HTMLAs = HTMLDoc.getElementsByTagName("a")
Set HTMLAs = HTMLDoc.getElementsByTagName("tr")
Set HTMLAs = HTMLDoc.getElementsByTagName("td")
Set HTMLAs = HTMLDoc.getElementsByTagName("div")
我试过了：
HTMLDoc.querySelector("a[title='Policy']").Click
'HTMLDoc.querySelector("a[href='/PolicySearch/policySearch_v30.cfm?module=policy&actionType=lookup']").Click 'no
'HTMLDoc.querySelector("a[href='/PolicySearch/policySearch_v30.cfm?module=policy&actionType=lookup']").Click 'no
'HTMLDoc.querySelector("A[href='/PolicySearch/policySearch_v30.cfm?module=policy&actionType=lookup']").Click 'NO
'HTMLDoc.querySelector("A[title='Policy']").Click 'no
这些都没有抓住元素。
这是我要单击的元素的 html：
<A title=Policy style="FONT-SIZE: 8pt; FONT-FAMILY: arial"
href="/PolicySearch/policySearch_v30.cfm?
module=policy&actionType=lookup" target=main nowrap> Lookup Policy
</A>
当我第一次进入我想要的页面时，这是框架的顶部：
<FRAMESET id=defaultFrame frameSpacing=0 border=0 frameBorder=no
rows=70,21,*,21,1><FRAME noResize src="/systemInfo/ScriptX/titleBar.cfm"
frameBorder=0 name=titleBar scrolling=no application="yes"><FRAME noResize
src="/producerTOC.cfm" frameBorder=0 name=producerTOC scrolling=no
application="yes"><FRAMESET id=BottomRow cols=1,*><FRAME noResize
src="toc.cfm" frameBorder=0 name=toc marginWidth=0 scrolling=no
application="yes"><FRAME noResize src="main.cfm" frameBorder=0 name=main
application="yes"></FRAMESET><FRAME noResize
src="/systemInfo/ScriptX/footerFrame.cfm" frameBorder=0 name=footerFrame
scrolling=no application="yes"><FRAME noResize src="" frameBorder=0
name=utilityFrame scrolling=no application="yes"><NOFRAMES></NOFRAMES>
但从这里我不知道如何进行。非常感谢任何建议或方向。

解决方案
选择器是正确的
a[title=Policy]
如果在其属性上使用框架/iframe，则可以访问其 contentDocument。例如，如果框架有一个 id
ie.document.getElementById(frameid").contentDocument.querySelector("a[title=Policy]").click
