Problems with ASP.Net 2.0 and JavaScript

[richard]

OK,

Im working with a DataList in .Net 2.0, the code shows the list when
the query has executed. I have the page feature in its own div and
display:none so its not visible until the list shows. Ive written
javascript in ASP.Net to show the DIV. The code is as follows:
jScript = "<script LANGUAGE=""java script"">" & vbNewLine
jScript = jScript & "function ToggleDiv(id){" & vbNewLine
jScript = jScript & "var elem = document.getEle mentById(id);" &
vbNewLine
jScript = jScript & "if (elem)" & vbNewLine
jScript = jScript & "{" & vbNewLine
jScript = jScript & " if (elem.style.dis play != 'block')" &
vbNewLine
jScript = jScript & " {" & vbNewLine
jScript = jScript & " elem.style.disp lay = 'block';"
&vbNewLine
jScript = jScript & " elem.style.visi bility = 'visible';"
& vbNewLine
jScript = jScript & " }" & vbNewLine
jScript = jScript & " else" & vbNewLine
jScript = jScript & " {" & vbNewLine
jScript = jScript & " elem.style.disp lay =
'none';" & vbNewLine
jScript = jScript & " elem.style.visi bility =
'hidden';" & vbNewLine
jScript = jScript & " }" & vbNewLine
jScript = jScript & " }" & vbNewLine
jScript = jScript & "}" & vbNewLine
jScript = jScript & "ToggleDiv('Pag e_Div');" & vbNewLine
jScript = jScript & "</sc" & "ript>"
Response.Write( jScript)
I dont get any errors, but the javascript doesn't execute either.
Anyone have any ideas?

I'm not a VB.NET specialist, but what happens if you replace vbNewLine with
"\n"

[sloan]

I think you gotta register it with the page (or are you not showing that
part?)

here is a sample I had ... written in vb.net

its actually a part of a class, where the constructor has the Page ... so I
can reuse it.

that's what _currentPage is all about.
I'd get a basic thing working first.. ( just an alert or something?) before
dealing with the hidden div stuff.


Private Sub CreateTrimJS()

Dim sb As StringBuilder = New StringBuilder

sb.Append("<!-- " & vbCrLf)
sb.Append("func tion trim(str) {" & vbCrLf)

''http://www.experts-exchange.com/Web/Web_Languages/JavaScript/Q_20959311.ht
ml

''sb.Append("al ert('got to trim function -->' + str);" &
vbCrLf)

sb.Append("var returnVal='';" & vbCrLf)

sb.Append("retu rnVal=str.repla ce(/^\s*|\s*$/g,"""");" &
vbCrLf)

''debug
''sb.Append("al ert('str -->*' + str + '*\nreturnVal--*' +
returnVal + '*');" & vbCrLf)
sb.Append("retu rn returnVal;" & vbCrLf)

''close the entire function
sb.Append("}" & vbCrLf)
sb.Append(vbCrL f & "// -->" & vbCrLf)


If (Not
_currentPage.Is StartupScriptRe gistered("someu niquevalueHere" )) Then
'prevents a "double register"

_currentPage.Re gisterStartupSc ript("someuniqu evalueHere", sb.ToString)
End If

End Sub

This works fine for me. However, It DOESN'T work if your div is AFTER
this block, it doesn't exist in the dom when you call the function with
the line:

ToggleDiv('Page _Div');

If your div is before this block, it works fine.

I advise putting the whole function in a .js file and including it into
your web page in a <scripttag between the <head.. </headsection.
That will make it easier to read/debug. I'd then put the
"ToggleDiv('Pag e_Div');" call in the onload event of the <bodytag.
That way, no matter where the DIV exists, IE will only call your toggle
function once the entire page is loaded into the DOM.
