[英]Excel VBA: auto click and open file from website
Thanks to Qharr, I have successfully performed auto search on the website.(My previous question: Excel VBA: Cannot perform auto search on website ) I have another question concerning the next step: I would always like to click the first link that appears after clicking the search button, and open the file in order to extract certain data. 感谢Qharr,我已经成功地在网站上执行了自动搜索。(我的上一个问题: Excel VBA:无法在网站上执行自动搜索 )我还有一个关于下一步的问题:我总是想单击出现在页面后面的第一个链接。单击搜索按钮,然后打开文件以提取某些数据。 Is there any ways to do that?
有没有办法做到这一点? Thanks!
谢谢!
Codes that I have at present: 我目前拥有的代码:
Option Explicit
Sub Searchstockcode()
Dim SearchString As String, SearchBox As Object, SearchButton As Object, ie As Object
SearchString = "2828"
Set ie = CreateObject("InternetExplorer.Application")
ie.Visible = True
ie.navigate "http://www.hkexnews.hk/listedco/listconews/advancedsearch/search_active_main.aspx"
While ie.Busy Or ie.readyState < 4: DoEvents: Wend
Set SearchBox = ie.document.getElementById("ctl00_txt_stock_code")
SearchBox.Value = SearchString
Set SearchButton = ie.document.querySelector("[src*='/image/search.gif']")
SearchButton.Click
While ie.Busy Or ie.readyState < 4: DoEvents: Wend
'Click the first result
Set TargetFile = ie.document.getElementById("ctl00_gvMain_ctl02_hlTitle")
TargetFile.Click
'Here I would like to open the file in excel, but I am stuck at the "save as" pop up.
'As long as the file can be opened, I should be able to complete the data extraction with my own codes.
ie.Quit
End Sub
You can extract the URL for the file download and binary file download. 您可以提取文件下载和二进制文件下载的URL。 In the example below, the file is stored in a variable
wb
for later use. 在下面的示例中,文件存储在变量
wb
以备后用。
In the following the filedownload link is extracted via TargetFile.href and passed to a function to perform ADODB binary download. 接下来,通过TargetFile.href提取filedownload链接,并将其传递给函数以执行ADODB二进制下载。 You could also pass the URL for download to URLMon as shown in my answer here .
您也可以通过网址下载到URLMON如图我的答案在这里 。
