如何使用excel visual basic单击节点树中的元素
如何使用excel visual basic单击节点树中的元素
提问于 2020-05-15 11:00:45
我正在尝试使用Excel VBA自动执行一项任务，并且我可以将所需的数据发送到网页，但是在网页中有一个节点树，要使我的代码正常工作，需要在将数据发送到网页以填充信息之前选择一个选择，而我不知道如何选择该节点树中的元素。我尝试通过id获取元素，但没有帮助。这棵树大约有18个元素，下面是其中一个元素的代码：
<span class="x-tree-node-indent"><img alt="" src="data:image/gif;base64,R0lGODlhAQABAID/AMDAwAAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw==" class="x-tree-icon"></span><img alt="" src="data:image/gif;base64,R0lGODlhAQABAID/AMDAwAAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw==" class="x-tree-ec-icon x-tree-elbow"><img alt="" src="data:image/gif;base64,R0lGODlhAQABAID/AMDAwAAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw==" class="x-tree-node-icon" unselectable="on"><a hidefocus="on" class="x-tree-node-anchor" href="" tabindex="1"><span unselectable="on">Credit And Rebill</span></a>我尝试了这个代码doc.getElementById("nd_17").Click，但对我不起作用。任何帮助我们都将不胜感激。
到目前为止，我用来填充数据的VBA代码是
Sub testing()
Dim IE As Object
Dim doc As HTMLDocument
Set IE = CreateObject("InternetExplorer.Application")
IE.Visible = True
IE.navigate "www.example.com"
Do While IE.Busy
Application.Wait DateAdd("s", 1, Now)
Loop
Set doc = IE.document
doc.getElementById("nd_17").Click
doc.getElementById("credit_and_rebill_bill_id").Value = "test"
End Sub完整的树代码是

我检查了您想要单击的节点的以下HTML代码。
<span class="x-tree-node-indent"><img alt="" src="data:image/gif;base64,R0lGODlhAQABAID/AMDAwAAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw==" class="x-tree-icon"></span><img alt="" src="data:image/gif;base64,R0lGODlhAQABAID/AMDAwAAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw==" class="x-tree-ec-icon x-tree-elbow"><img alt="" src="data:image/gif;base64,R0lGODlhAQABAID/AMDAwAAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw==" class="x-tree-node-icon" unselectable="on"><a hidefocus="on" class="x-tree-node-anchor" href="" tabindex="1"><span unselectable="on">Credit And Rebill</span></a>您可以尝试遍历所有锚标记，并尝试匹配类名、制表符索引属性和内部文本值。如果匹配，则可以单击该元素。
示例：
Sub test()
Dim URL As String
Dim IE As Object
Dim elements, element, attr
Dim item As String
Set IE = CreateObject("InternetExplorer.Application")
IE.Visible = True
URL = "D:\Tests\16.html"
IE.Navigate URL
Do While IE.ReadyState = 4: DoEvents: Loop 'Do While
Do Until IE.ReadyState = 4: DoEvents: Loop 'Do Until
Set elements = IE.document.getElementsByTagName("a")
For Each element In elements
If element.className = "x-tree-node-anchor" And element.tabIndex = "1" And element.innerText Like "*Credit And Rebill*" Then
element.Click
End If
Next element
Set IE = Nothing
End Sub输出：
此外，您可以根据自己的需求修改代码示例。

假设你想通过锚元素点击选项，那么你可以使用nth-of-type。您需要指定要单击的选项。你可以创建一个字典，它自动收集锚点的相关视觉文本，例如Settle Invoice，然后添加适当的索引，例如1作为字典的值。您可以通过在0 to ie.document.querySelector(".x-tree-node-ct .x-tree-node .x-tree-node-anchor").Length -1的循环中填充一个字典并简单地将+1添加到循环计数器来获得适当的索引值来插入到dict中，从而很容易地做到这一点。使用返回的nodeList中的索引项并获取.innerText来获取键。
一般而言：
ie.document.querySelector(".x-tree-node-ct .x-tree-node:nth-of-type(n) .x-tree-node-anchor") 其中n将是适当的索引。
如上所述，选择19个中的第一个将是：
ie.document.querySelector(".x-tree-node-ct .x-tree-node:nth-of-type(1) .x-tree-node-anchor").click页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
