I use js sdk to get data from facebook, I need to post this data to the server. and depending on this data I want to show something to the user.
if I use ajax I can't update sever text fields (and cant show the user the correct message).
is there a way to use ajax and to update a specific text box on the page?
$.ajax({
type: "POST",
url: 'myurl.aspx',
data: "id=" + id
});
on the load event of the page on the server side i have
If Not IsPostBack Then
Dim id As String = Request.Form("id")
If String.IsNullOrEmpty(id) Then
Else
Dim counter As Integer = 0
Dim code As String = ""
Dim flag As Boolean = True
If gotCode(id) Then
result.InnerHtml = "got already!"
Else
code = generateCode()
saveCodeInDB(code, id)
result.InnerHtml = code
End If
End If
End If
Jquery ajax has a setting method "success" that is called if the request succeeds, one of the parameters is the data returned from the server. You can return the data from the server and than update the html in jquery. For example:
You could also call the page from JavaScript but do not use Ajax. Just redirect to the page:
window.location.href = "myurl.aspx?id=" + id;
Then in the page behind for myurl.aspx get the data using the id (which it looks like you are doing) but instead of putting it on the response, just populate the values of textboxes or other controls on the page.
it's a great idea, no need for post, but in such a case I get into an endless loop. when the page is loaded again it try to retrieve the facebook id of the user again. and refresh again.

$.ajax({ url: url, type: "GET", dataType: "html", success: function (result) { $('#spanDetails').html(result); }, error: function (xhr, ajaxOptions, thrownError) { alert(thrownError); } });Look at JQuery Ajax: http://api.jquery.com/jQuery.ajax/
