Passing a string from .NET to a javascript variable

Question

I have tried many ways to pass a string from .net to javascript including .NET serializer, and register startup scripts.

I am looking for the simplest way to populate a javascript variable with a string generated in code behind.

This is what I am currently trying but output is ""

I am open to other suggestions.

VB.NET

Public Property ServerVariable As String

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
  Dim ServerVariable = "'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'"
End Sub

JAVASCRIPT

var data = "<%= ServerVariable %>";
...
List : [data]

DESIRED RESULT

List : ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']

@OP: why have you deleted your last question. I just wanted to post my answer. You've asked me to show you an example. — Tim Schmelter

@TimSchmelter because I was being savaged by the vultures for not posting a question to their liking. If you could offer me advice on the right direction to take It would be greatly appreciated. — DreamTeK

@Obsidian: some people have an off-day. Edit your question by providing the result of what you've tried(a compiler error). Then the close-vote("Questions seeking debugging help ("why isn't this code working?") must include the desired behavior, a specific problem or error") is pointless. Then undelete it. If you don't want to do that, use a collection type rather than multiple properties. You could do what you want with reflection but that is the very last resort and unnecessary in this case. — Tim Schmelter

This should be a comment, sorry, btw you can access to public props in the aspx;ascx, so this should help

vb.net

Public Property ServerVariable As String

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
  ServerVariable = "['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']"

End Sub

JS

var data = "<%= ServerVariable %>";

You are doing it correctly, only thing is that you need to do .split(",") in javascript to get desired result.

Like var list = console.log(data.split(","));

Does this mean I should remove my commas from string in vb?

Arindam Nayak Over a year ago

No you should keep it as it is, that is the key point here, as you can see that i am splitting that with comma.

Missing get and set values. Passed variable ServerVariable needs to have a value applied to it.

  Private MyVar As String = ""

  Public Property ServerVariable As String
    Get
      Return MyVar
    End Get
    Set(value As String)
      MyVar = value
    End Set
  End Property

  MyVar = "['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']"
