我有一个在页面加载事件中动态创建的 ASP 表。在那种情况下,我用标题填充 ASP 表,然后是一个指向 .ashx 页面的 ASP .NET 超链接控件,以提供一个文件供客户端下载。
对于特定文件(图像文件),我想启动一个 javascript 函数来打开一个新窗口,其中显示该文件。我拥有执行此操作的所有代码,但我无法让我的 Javascript 函数在超链接 NavigateURL 属性中工作。我是 Javascript 的新手,所以我不确定我错过了什么。我可以做我想做的事吗?我不能使用表格控件吗?
ASP代码隐藏
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim iWineID As Integer
If Not Integer.TryParse(Request.Params("WineID"), iWineID) Then Throw New InvalidOperationException("Invalid request")
Me.lblWineName.Text = Utils.GetWineName(iWineID)
Dim dtDocs As New dsDocs.docsDataTable
Using taDocs As New dsDocsTableAdapters.docsTableAdapter
dtDocs = taDocs.GetDataByProdIDOrWineID((Utils.GetProducerIDByWineID(iWineID)), True, iWineID)
End Using
If dtDocs.Rows.Count = 0 Then
Me.lblDocsFound.Text = "No documents available for this wine."
Else
Me.NumberDocs(dtDocs)
For Each drDoc As dsDocs.docsRow In dtDocs
Dim myRow As New TableRow
Dim myTitleCell As New TableCell
Dim myDLCell As New TableCell
Dim myHL As New HyperLink
Select Case drDoc.doc_type_id
'window.open('preview.aspx?WineID=' + nWineID', 'height=' + nWindowHeight + ',width=' + nWindowWidth + ',status=no,toolbar=no,menubar=no,location=no,scrollbars=' + bScrollbars + ',resizable=' + bScrollbars + ',titlebar=no');
Case Constants.DocType.BottleShot, Constants.DocType.Label, Constants.DocType.Logo
myHL.NavigateUrl = "javascript:OpenPrev('" & drDoc.doc_id & "');return false;" '"javascript:window.open('~/Home/docpreview.aspx?DocID=" & drDoc.doc_id '& "','_blank', 'height=600, width=600,status=no,toolbar=no,menubar=no,location=no,scrollbars=no,resizable=no,titlebar=no'"
'"~/Home/docpreview.aspx?DocID=" & drDoc.doc_id
myHL.Text = "View"
Case Else
myHL.NavigateUrl = "~/Home/docs.ashx?DocID=" & drDoc.doc_id
myHL.Text = "Download"
End Select
myTitleCell.Text = StrConv(drDoc.doc_type_name, VbStrConv.ProperCase)
myDLCell.Controls.Add(myHL)
myRow.Cells.Add(myTitleCell)
myRow.Cells.Add(myDLCell)
Me.tableDocs.Rows.Add(myRow)
Next
End If
End Sub
Javascript
function OpenPrev(DocID){
var objWin
var myURL
alert("GO!");
myURL='~/Home/docpreview.aspx?DocID=' + DocID;
objWin=window.open(myURL, 'Doc View', 'width=600,height=600,resizable=no,scrollbars=yes,toolbar=no');
}
最佳答案
您需要先解析 URL。
尝试更改您设置 NavigateURL 的任何地方,例如:
myHL.NavigateUrl = "~/Home/docs.ashx?DocID=" & drDoc.doc_id
收件人:
myHL.NavigateUrl = HttpContext.Current.Request.Url.Scheme + "://" + HttpContext.Current.Request.Url.Authority + HttpContext.Current.Request.ApplicationPath + "Home/docs.ashx?DocID=" & drDoc.doc_id
