之前取网页是如何取全部页共280条记录的？求分享。

看到你在另一个帖子上的回复了，就是抓网址，page翻页也可以，你抓的那个更方便

我的“body”里为什么是空白的呢？

我是照着你的例子来操作的，我再检查下

此用户被禁言

不明白为什么，使用IE对象与msxml2对象的时候，表格不一样
这个是在第二个

1. Sub 作业()
   
2.     Dim url, html
   
3.     Set html = CreateObject("htmlfile")
   
4.     url = "http://data.bank.hexun.com/lccp/Jrxp.aspx?col=1&tag=desc&date=2014-10-26&page="
   
5.     With CreateObject("msxml2.xmlhttp")
   
6.         For p = 1 To 3
   
7.             .Open "POST", url & p, False
   
8.             .send
   
9.             html.body.innerhtml = .responsetext
   
10.             Set tb = html.all.tags("table")(1).Rows
    
11.             For i = 0 To tb.Length - 1
    
12.                 n = n + 1
    
13.                 For j = 0 To tb(i).Cells.Length - 1
    
14.                     Cells(n, j + 1) = tb(i).Cells(j).innertext
    
15.                 Next
    
16.             Next
    
17.         Next
    
18.     End With
    
19. End Sub

复制代码

IE的是在第3个

1. Sub 作业3() 'ie
   
2.     Set ie = CreateObject("internetexplorer.application")
   
3.     ie.navigate "http://data.bank.hexun.com/lccp/Jrxp.aspx?col=1&tag=desc&date=2014-10-26&page=1"  '没有循环，只是看表在第几个
   
4.     ie.Visible = True
   
5.     Do While ie.ReadyState <> 4
   
6.         DoEvents
   
7.     Loop
   
8.     Set a_s = ie.Document.all.tags("table")(2).Rows   ''''''''''这是不同，msxml2这个表后面要填写数字1
   
9.             For i = 0 To a_s.Length - 1
   
10.                  n = n + 1
    
11.                   For j = 0 To a_s(i).Cells.Length - 1
    
12.                     Cells(n, j + 1) = a_s(i).Cells(j).innertext
    
13.                   Next
    
14.              Next
    
15.     MsgBox "数据抓取已经完成", 0 + 64, "此用户被禁言提示"
    
16. End Sub

不明白为什么。。。表格在的位置不一样，
