html - 通过 VBA 使用 QuerySelector 单击 HTML 元素

Question

我正在尝试使用 VBA 自动访问网页。我正在通过登录屏幕，但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达到我在过去展示过的效果。两者都无济于事。我已经尝试了 4 种不同的方法来获取标签，其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:

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

而且这些都没有捕获元素。

这是我要点击的元素的 html:

<A title=Policy style="FONT-SIZE: 8pt; FONT-FAMILY: arial" 
href="/PolicySearch/policySearch_v30.cfm? 
module=policy&amp;actionType=lookup" target=main nowrap>&nbsp; Lookup Policy 
&nbsp;</A>

这是我第一次进入我想要的页面时框架的顶部:

<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> 

但从这里我不确定如何进行。非常感谢任何建议或指导。

Answer 1

选择器正确

a[title=Policy]

如果有框架/iframe，则使用其属性来访问其 contentDocument。例如。如果框架有一个 id

ie.document.getElementById(frameid").contentDocument.querySelector("a[title=Policy]").click
