实现模拟网页点击按钮的功能代码如下:
Private Sub Command1_Click()
WB1.Navigate Text1
End Sub
Private Sub Command2_Click()
Timer1.Enabled = True
End Sub
Private Sub Command3_Click()
Unload Me
End Sub
Private Sub Command4_Click()
Dim vDoc, vTag
Dim I As Integer
Set vDoc = WB1.Document
List1.Clear
For I = 0 To vDoc.All.length - 1
If UCase(vDoc.All(I).tagName) = "INPUT" Then
Set vTag = vDoc.All(I)
If vTag.Type = "submit" Then
List1.AddItem vTag.Name
Select Case vTag.Name
Case "btnBack"
vTag.Click
End Select
End If
End If
Next I
End Sub
Private Sub Form_Load()
Timer1.Enabled = False
Timer1.Interval = 1000
End Sub
Private Sub Timer1_Timer()
Dim a As Long
a = a + 1
Label1 = "已经运行了" & Fix(a / 60) & "分钟"
If a Mod 600 = 0 Then
Command4_Click
End If
End Sub
Private Sub Command1_Click()
WB1.Navigate Text1
End Sub
Private Sub Command2_Click()
Timer1.Enabled = True
End Sub
Private Sub Command3_Click()
Unload Me
End Sub
Private Sub Command4_Click()
Dim vDoc, vTag
Dim I As Integer
Set vDoc = WB1.Document
List1.Clear
For I = 0 To vDoc.All.length - 1
If UCase(vDoc.All(I).tagName) = "INPUT" Then
Set vTag = vDoc.All(I)
If vTag.Type = "submit" Then
List1.AddItem vTag.Name
Select Case vTag.Name
Case "btnBack"
vTag.Click
End Select
End If
End If
Next I
End Sub
Private Sub Form_Load()
Timer1.Enabled = False
Timer1.Interval = 1000
End Sub
Private Sub Timer1_Timer()
Dim a As Long
a = a + 1
Label1 = "已经运行了" & Fix(a / 60) & "分钟"
If a Mod 600 = 0 Then
Command4_Click
End If
End Sub

看一下dom吧,web控件有一个属性叫document,我们可以使用它的函数:getelementById或者getelementByTagName来查找页面中的元素,然后调用它的click方法就ok了。

源代码为INPUT type="image" src="images/cx_enter.gif" width="41" height="16" border=0 name="imageField">
可否写成 vDoc.All.Item("imageField").Click

貌似不行哦,你用getelementByName获得这个input后,再调用不久得啦
