B4J Question [ABMaterial] How to download text file from remote server

[jinyistudio]

Hi

My ABMaterial App run in the VPS(not local). How to download text file from VPS to local(browser side) ?

 

[Cableguy]

I was under the impression that any link pointing to a file would automatically become a download on client (browser) side... have you tried it?

I want to download file use a sub not to click a link.

You need to do an Ajax call.

Sub btn1_Clicked(Target As String)
    page.CallAjax("0001", "../uploads/myCSV.csv", "GET", "", "")
End Sub

Sub Page_AjaxError(uniqueId As String, error As String)
    Log(error)
End Sub

Sub Page_AjaxResult(uniqueId As String, result As String)
    Log(result)
End Sub

I try to use following code to download a csv file from VPS

File.Writestring(fd1,filename,csv.ToString)
page.CallAjax("0001", jyString.Slash($"..\uploads\${filename}"$), "GET", "", "")

its event can work but it cann't downalod anything to browser side

Sub Page_AjaxResult(uniqueId As String, result As String)
    Log(result)
End Sub
