Question

I think that this should be pretty easy but I’m not quite sure how to wire things up.

I have a page on which the user can define a query. When done, the user enters a name for the query and presses a button. I’d like to process the button click, make a text label (or Span) visible for a few seconds and then have it fade out.

Since it is a postback, I can turn an ASP:Label control to visible – that’s easy. Now how do I get jquery to make the label fade away after a few seconds? In a broader sense, how do you get a postback to trigger a jquery method?

Bonus for the simplest solution!

Start the asp label text as empty.

<asp:Label id="myLabel" runat="server"></asp:Label>

Then you can fade out the label every page load and set the text of the asp label after hitting the button.

Protected Sub btn_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btn.Click
  myLabel.Text = "You hit the button"
End Sub

    $(document).ready(function() {
        $('#myLabel').fadeOut(3000, function() {
            $(this).html(""); //reset the label after fadeout
        });
    });
