vb獲取webbrowser源碼
1. VB如何獲取webbrowser源碼指定文本
第一個紅框的文本:
WebBrowser1.Document.getElementById("list_uin").getElementsByTagName("label")(0).innerText
第二個紅框的文本:
WebBrowser1.Document.getElementById("list_uin").getElementsByTagName("label")(1).innerText
2. 如何用vb.net獲得網頁的源代碼
Dim url As String=" 網址"
Dim httpReq As System.Net.HttpWebRequest
Dim httpResp As System.Net.HttpWebResponse
Dim httpURL As New System.Uri(url)
httpReq = CType(WebRequest.Create(httpURL), HttpWebRequest)
httpReq.Method = "GET"
httpResp = CType(httpReq.GetResponse(), HttpWebResponse)
httpReq.KeepAlive = False ' 獲取或設置一個值,該值指示是否與
Internet資源建立持久連接。
Dim reader As StreamReader = _
New StreamReader(httpResp.GetResponseStream,
System.Text.Encoding.GetEncoding(-0))
Dim respHTML As String = reader.ReadToEnd() 'respHTML就是網頁源代碼
3. VB WebBrowser 獲取網頁內容~
private
sub
command1_click()
set
vdocs
=
webbrowser1.document.getelementsbytagname("ul")
text1.text
=
vdocs(32).innertext
end
sub
不過,你既然都打開網頁了,已經看到了,還提取它干什麼?
如果你是想用軟體自動提取這個信息,到其它地方用。那就不要用webbrowser,這個太慢。直接用
inet控制項,或者用xmlhttp等獲取源碼再取信息。
4. 如何用vb webbrowser獲取帶框架網頁的全部源代碼
用vb webbrowser獲取帶框架網頁的全部源代碼,指令如下:
WebBrowser1.Document.frames(0).Document.documentElement.outerHTML
遍歷框架就可以得到所有的(WebBrowser1.Document.frames(0).count框架個數)。
5. VB 獲取網頁源碼 你的這個是怎麼解決的.能和我說一下嗎.謝謝
1、提取:用這個vb小程序可以!
6. 用vb獲取任一網頁源代碼,要完整的!!!,可以用webbrowser控制項
'你把下面的代碼保存為Form1.frm,然後雙擊打開該文件,運行後按提示即可看到結果。
'呵呵,夠詳細了,再不會我也沒辦法了。
'====文件Form1.frm====
