我正在开发一个网络爬虫。代码如下：
'============ Module 1 ======================
Sub test()
Dim eRow As Long
Dim ele As Object
Set sht = Sheets("Sheet1")
RowCount = 1
sht.Range("A" & RowCount) = "Title"
sht.Range("B" & RowCount) = "Company"
sht.Range("C" & RowCount) = "Location"
sht.Range("D" & RowCount) = "Description"
eRow = Sheet1.Cells(Rows.Count, 1).End(xlUp).Offset(1, 0).Row
Set objIE = CreateObject("InternetExplorer.Application")
myjobtype = InputBox("Enter type of job eg. sales, admin ")
myzip = InputBox("Enter zipcode of area where you wish to work")
With objIE
.Visible = False
.navigate "http://www.jobs.com/"
Do While .Busy Or _
.readyState <> 4
DoEvents
Loop
Set what = .document.getElementsByName("q")
what.Item(0).Value myjobtype
Set zipcode = .document.getElementsByName("where")
zipcode.Item(0).Value = myzip
'*====================================================*
.document.getElementByld("JobsButton").Click
'*=====================================================*
Do While .Busy Or _
.readyState <> 4
DoEvents
Loop
For Each ele In .document.all
Select Case ele.classname
Case "Result"
RowCount = RowCount + 1
Case "Title"
sht.Range("A" & RowCount) = ele.innertext
Case "Company"
sht.Range(B & RowCount) = ele.innertext
Case "Location"
sht.Range("C" & RowCount) = ele.innertext
Case "Description”"
sht.Range("D" & RowCount) = ele.innertext
End Select
Next ele
End With
Macro1
Set objIE = Nothing
End Sub
'======================单元2 ======================================================================================================================================================================================================================================================
Sub Macro1()
' Macrol Macro
' Formatting imported data
Columns("A:D").Select
Selection.Columns.AutoFit
With Selection
.VerticalAlignment = xlTop
.Orientation = 0
.Addlndent = False
.IndentLevel = 0
.ShrinkToFit = False
.ReadingOrder = xlContext
End With
Range("D1").Select
Columns("D:D").ColwmnW1dth = 50
Columns("A:D").Select
Selection.Rows.AutoFit
End Sub
'================================================= ===========
此代码的问题在于，以前有一个单击按钮的ID，但现在他们已删除了该ID。我尝试使用许多示例将===中的内容替换为许多示例，但大多数情况下都没有成功，该错误是我在本网站上使用的其他建议的“必需对象”。有人可以帮我替换===内单击按钮的部分吗。
该站点上按钮的HTML现在已更改为
<button type="submit" class="btn">Search Now</button>
================================================== ===========这是代码的工作方式：http : //www.youtube.com/watch?v=cSoRVZKRkvY
.document.getElementsByTagName("button")(0) 应该能够捕获搜索按钮
而且我为您做了更多的工作。之后使用以下代码.document.getElementsByTagName("button")(0).click
Set resultset = .document.getElementsByTagName("article")
RowCount = 2
For Each result In resultset
sht.Range("A" & RowCount) = result.ChildNodes(0).innertext
sht.Range("B" & RowCount) = result.ChildNodes(1).innertext
sht.Range("C" & RowCount) = result.ChildNodes(2).innertext
sht.Range("D" & RowCount) = result.ChildNodes(3).innertext
RowCount = RowCount + 1
Next
