Question

我找不到伪造具有动态ID的html表笨拙的方法- 每当我打开新会话时，id都会更改。

如果我手动用“ 1”（小时）填充列（1/10/2019）-在下一个会话中，列（1/10/2019）的ID变为常量，我可以使用“ application.sendkeys（例如，将“ 7”）更改为“ 7”（小时）。

如何填充html表中以前没有手动插入任何值的列？处理此任务的正确方法是什么？

Sub Treport()

'Make the app work faster?
Application.ScreenUpdating = False
Application.DisplayAlerts = False
'--------------------------------
Dim sht As Worksheet
Set sht = ThisWorkbook.Sheets("Report_Time") 'my data will be stored here
'--------------------------------
Dim LastRow As Long
LastRow = sht.Cells(sht.Rows.Count, "A").End(xlUp).Row 'range definition
'--------------------------------
Dim i As Long            'Will be used for a loop that navigate to different url
For i = 2 To LastRow     'variable range
Dim IE As Object         'Internet Explorer declaration
Set IE = CreateObject("InternetExplorer.Application") 'Opens browser
IE.Visible = True

IE.navigate sht.Range("A" & i).Value 'My url that I want to navigate to
While IE.readyState <> 4 Or IE.Busy: DoEvents: Wend 'wait until site fully loads

Dim Doc As New HTMLDocument 'Will be used for the main html page
Set Doc = IE.document

Doc.getElementById("imgLastWeek").Click 'Here I click to navigate within the timesheet to the desired time range
While IE.readyState <> 4 Or IE.Busy: DoEvents: Wend 'wait untill page loads again
Doc.getElementById("9da306a8-b813-46ff-b94f-45636f401ba8").Click 'need to click the column before inseting a value
Application.Wait Now + TimeValue("00:00:2")
Application.SendKeys ("7") 'here I change value from "1" to "7" in a clumn that I have manualy inserted number before, that is why the id is constant

Next i

Application.DisplayAlerts = True
Application.ScreenUpdating = True

End Sub

我希望根据任务ID +列日期在列中插入小时。如果需要更多的html来了解表的结构，请提出建议，我将复制更多的代码。

Answer 1

使用IE浏览器时，您可以访问范围更广的选择器，包括一些pseudo class css selectors，例如nth-of-type（最后我触摸:last-child）。这与通过.querySelector使用HTMLDocument对象的MSHTML方法可以应用的方法相反。

因此，对于所显示的HTML，您可以使用nth-of-type选择器来抓取感兴趣的行（显示红色和蓝色矩形的行），以tr标签选择第n个出现的行，父表由ID标识（＃是id selector）。

让我们看看根据返回的元素进行匹配时该行的外观：

应该类似（请记住，在我添加td元素选择器之前，不会显示空的td元素-下一步显示）：

现在，让我们细分一下，使用后代组合器和td元素选择器在该行中包括子元素td（表单元）：

在上面，您现在可以查看该行内的所有表格单元格，并使用您看到的属性，位置或两者的组合来定位感兴趣的元素（表格单元格）。

例如，如果您提前知道红色星期一7号的日期，则可以使用celldate属性定位并将其添加到选择器链中：

#tblTimeSheet_tblMain tr:nth-of-type(4) td[celldate='1/7/2019']

如果不知道日期，则可以再次使用位置，并在nth-of-type行的td单元格中使用tr索引（请注意，这是base-1而不是0）：

#tblTimeSheet_tblMain tr:nth-of-type(4) td:nth-of-type(7)

这很像通过x行y列语法进行引用。

上面显示的css选择器通过.querySelector的{{1}}方法来应用，例如

ie.document

或

ie.document.querySelector("#tblTimeSheet_tblMain tr:nth-of-type(4) td:nth-of-type(7)").value = "xyx"

我无法使用浏览器和vba库对此进行测试，但我知道ie.document.querySelector("#tblTimeSheet_tblMain tr:nth-of-type(4) td:nth-of-type(7)").innerText = "xyx"以及attribute = value selectors和descendant combinators均受支持。

在这种情况下，应该知道还支持last-child选择器，并且在引用最后nth-of-type行时，还可以使用：

tr

其他注意事项：

选择器越长，选择器将越慢。尽管使用现代浏览器，您在谈论的性能差异很小。
此外，最右边的是键选择器，并且应该尽可能地具有选择性，例如id选择器（如果可能），否则类选择器...选择的顺序已记录在案。所有这些都应该尽可能有选择性，但是记住从右到左的阅读很重要。
此#tblTimeSheet_tblMain tr:last-child td:nth-of-type(7)应该类似于以下链接：#tblTimeSheet_tblMain tr:nth-of-type(4) td:nth-of-type(7)，但性能更高。
