Question

I have got an ASP page that does some back-end processing. It calls a stored procedure which will return a status value if the process is complete. The whole processing time can last around 10-30 seconds, depending on the amount of input data.

During this period of time, I guess it’d be much better to display a loading image or text than just a blank page. At least in this way the user knows the her request is being processed and just need to wait for it to finish.

I am not sure how we could implement this with classic ASP. Any ideas?

Thanks very much.

EDIT:

Well I guess there’s something I didnt explain very clearly earlier. The actual scenario here is:

I have got 2 asp pages, A.asp and B.asp. User clicks a button on A.asp and it will submit form to B.asp, and B.asp is the processing page that will call the back-end stored procedure. When the B.asp is done with processing, it will redirect user to another page.

So the problem I have is, whenever user clicks the button of A.asp and gets to B.asp, there’s just a blank page, even though I already had HTML code (displaying a loading image) placed at the very beginning of B.asp (the asp code that connects the database is way below). I don’t know why it’s not displaying image when it’s loaded.

When you say displaying loading message, I interpret that you’re using ajax. In ajax start you can display that image, and in ajax complete callback you can hide the loading image. Please provide some code examples if possible.

In case if jQuery ajax, you can use:

$('#loaderImage').show();
$.ajax({
    // Other ajax parameters
    success: function () {
       // hiding the image here
       $('#loaderImage').hide();
    }
});
