使用onmouseover在框架中渲染文本 [英] Rendering text in a frame with onmouseover

问题描述

假设:我想在与另一个框架中的网格分开的框架中呈现文本.当光标经过单元格时，必须渲染文本，而当我移出单元格时，文本必须消失.我得到了数据，但是很奇怪，如果两个单词之间有空格，尽管有数据，但文本不会出现.

Suppose: I want to render text in a frame separated from a grid in another frame. When the cursor passes over a cell the text must be rendered and when I move out the text must disappear. I get the data but strange if there''s a space between two words, the text will not appear, although the data are there.

我在转发器中检索数据，并使用repeater_itemdatabound操作它们.

I retrieve the data in a repeater and I manipulate them with repeater_itemdatabound.

代码:

Sub Repeater_ItemDataBound(ByVal s As Object, ByVal e As RepeaterItemEventArgs)

    'here I retrieve the data
    Dim reader As SqlDataReader = cm.ExecuteReader()
    While reader.Read()
        'Response.Write(reader("DSOmschrijving"))
If reader("DSOmschrijving") <> "" Then
            var1 = 1
var2 = reader("DSOmschrijving").ToString
        End If
    End While
    ' Test to render them
    ' response.write(var2) ---> and indeed the text is rendered on
    ' the screen(principal frame).
    '  here the text must be in frame2
    If var1 = 1 Then
LabDSCode.Text = "<td bgcolor='#999999'>" & 
     "<a href='details.aspx?ds=" & dataLLDCode & 
     "&didsug=" & var2 & 
     "' onMouseOver=parent.frames[1].document.open();parent.frames[1].document.write('" & var2 & "');parent.frames[1].document.close();>".ToString & 
     "&nbsp&nbsp&nbsp&nbsp&nbsp" & "</a>"
    Else
    End If
    cn.Close()
    reader.Close()
    ' If I delete all the spaces (&nbsp) it works , but otherwise not.

如果有人知道解决方案?

If there''s someone who knows a solution ???

很多东西....

推荐答案

我假设您正在使用AJAX来完全正常工作. ;您为什么不将问题标记为关于ASP.NET?

I assume you''re using AJAX for this to work at all.  Why did you not tag your question as being about ASP.NET ?

添加一个额外的表格元素对我来说似乎很奇怪，为什么不布置您的表格并只操作它的内容呢?

Adding an extra table element seems odd to me, why not lay out your table and only manipulate it''s contents ?
