Processing... Please wait child window

[Karan Jain]

Hi,
I am writing an upload application.
My requirement is:
I need to show a modal child window when i submit a file for upload saying "Processing... Please wait". The request should get submitted after this window is shown and when the request completes and response comes back this window should get closed while loading the main page.
So the window should remain visible while the request is being processed and closed when the request completes.

Is is possible to do this? if Yes... How?

1) I was tring to do window.ShowModalDialog and the control will not pass till i close this dialog...
2) then i was trying window.open(jspPage)... but i was not able to close this small window when i am coming back in OnLoad.

Anyhelp is appreciated...
Thanks,
Karan

Reveal a hidden positioned div just prior to submitting.

Hi Bear,
Thanks for the reply...

I am using hidden div but and i wanted to show an animated image to do so.
So what i did is loaded 4 images and call method to animate them with 500 ms delay.

  
timeDelayInms = 500;
imageNumber = 0;
totalImageCount = 4;
var uploadingImageArray;
 
uploadingImageArray = new Array(4);
 
for (i = 0; i < totalImageCount; i++) {
uploadingImageArray[i] = new Image();
uploadingImageArray[i].src = 'images/uploading_ani_' + (i) + '.gif';
} 
 
function rotate() { 
 
document.getElementById("uploading").src = uploadingImageArray[imageNumber].src;
imageNumber++;
        if(imageNumber >= totalImageCount) imageNumber = 0;
 
setTimeout("rotate()", timeDelayInms);
}

The images are getting loaded and working fine on my local host. But when i deploy the same on my test server the image does not show up.

I used IEWatch to see the problem and found that the get is aborted when trying to fetch the image.

I am not sure why its having this problem. When the page is loading its able to load all the images in array, but when it tries to animate it is having problem.

Any help is appreciated.

Thanks and regards,
Karan

Once you submit the page, all processing stops, so you can't do anything active like animations or even show animated gifs. If you want the page to remain alive during the processing, you'll need to submit it in the background with something like AJax, or to an iframe.
