I am assigning some text to Label after button click as follows: protected void

  • 0

I am assigning some text to Label after button click as follows:

protected void Button1_Click(object sender, EventArgs e)
{
    Label1.Text = "Hello";
}

After some amount of time, say 30seconds, I would like to clear the Label text.
Can any one help me?
I tried the following script, but it doesn’t work for me.

$(document).ready(function() {
    $('#Label1').fadeOut(3000, function() {
        $(this).html(""); //reset the label after fadeout
    });
});

My design

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script type="text/javascript">
        $(document).ready(function() {
        $('#<%= myLabel.ClientID %>').fadeOut(3000, function() {
                $(this).html(""); //reset the label after fadeout
            });
        });
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    <asp:Label id="myLabel" runat="server"></asp:Label>
        <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
    </div>
    </form>
</body>
</html>

    In order to run some code after specified time you need to wrap the code in ready handler in

    setTimeout(code, timeInMsAfterWitchToRunCode)

    call. What you are doing is fading out immediately over a 3 seconds time. 3000ms that you are passing is parameter to fadeOut function telling it how long fading out should take.

    Here you have working example:

    Note that in case of ASP.NET app you should use:

    $('#<%= Label1.ClientID %>')

    to select label. That is because you don’t know the id of the control until runtime when control has runat=”server” attribute set.
