Question

I am Working in ASP.NET and C#.

In my Application i have a registration form in which there is a label which shows the success and failure of the registration.The text for that label is from codebehind based on the condition.Now what i need is to hide the label after sometime (say 5sec) on clicking the submit button.I have tried this using javascript but its not working properly.please let me know whats the mistake or give ur sugessions.

Script:

    function HideLabel() {
        document.getElementById('<%= lbl1.ClientID %>').style.display = "none";
    }
    setTimeout("HideLabel();", 5000);

Answer 1

You have wrong syntax of setTimout. You have to pass name of function, remove the quotes and also pass name not call the function. One more thing to take care is to put the code just before the closing body tag to ensure the availability of html elements.

Change

setTimeout("HideLabel();", 5000);  

To

setTimeout(HideLabel, 5000);
