You’ve probably seen these used in various places in your ServiceNow instance.
To show a loading dialog…
var loadingDialog = new GlideDialogWindow("dialog_loading", true);
loadingDialog.setTitle('Loading...'); //Set the loading dialog title here...
To hide that same loading dialog…
Another great example is a customization I created to deal with long-loading forms. The customization required that a loading dialog be displayed before the form loaded, and that the loading dialog be destroyed when everything on the form finished.
ON my incident form I’m calling client scripts to show hide various fields but if I try using showLoadingDialog(); before the script its not showing it. Any reason why it is not shown on the form.
I’m not sure why this would happen, but I can’t reproduce it at https://demo.service-now.com. The best thing to do is try it out there and see what you get. If you’re still having an issue when you try it on the demo instance then post your code here and I’ll see if I can help.
I saw your script on Demo instance. And if there is a alert in the script then dialogBox is displayed. But if alert is removed and the script is modifed as below it does not show dialog box.
//Type appropriate comment here, and begin script below
var s = 3;
var n=new Date();
The code is working, but it is blowing right by the dialog and hiding it before it gets a chance to display. It takes a second for the dialog to get initiated and by the time it does, your script has finished and closed the dialog.
A very cool tip indeed! Is it by any chance possible to alter the title of the dialog window?
Good question. I haven’t tested this extensively, but it looks like you can by using the long-hand way of initiating the dialog and including ‘setTitle’. Let me know how this works…
loadingDialog.setTitle('Hello World!'); //Set the loading dialog title here...
I’ve tried this suggestion to change the dialogue window title, and it works great – Thanks Mark.
Can the “showloadingdialog” be issued from a List Context UI Action? I have a UI action setup to execute a scheduled job and I wanted to display the Loading dialog for a few seconds while the import completed.
Thanks for any help.
It can be. You just need to use a ‘Client’ type of UI action to call the function containing the loading dialog. I think the challenge will be hiding the loading dialog once it is loaded though. You’ll have to figure out when and how you can initiate that trigger. Maybe if you used a synchronous ajax call you could initiate the loading dialog, make the ajax call, and then wait until the call came back to hide the dialog, all in the same UI action script.
This works great. Thanks for the solution.
But for some users who uses IE this is not working, and these users use IE8. Did you see the issue before.
I haven’t seen that issue but if I had to guess I would say it is because of a failure somewhere else in one of your client scripts. Check the event log to see if there are any errors.
I checked event and error logs, but nothing is showing up there. Also, if there is a failure in some thing else, all the users should be affected. But only this specific user is affected and for this particular user it is working on other browsers but not on IE8. He is facing this error after this implementation.
How to modify the position and background color etc of Dialog?
we call showLoadingDialog() in a few places in our client scripts and it’s working great, but now I’m looking into how it works, and I can’t find a UI Page called “dialog_loading”. Should there be one?
I haven’t dived into the specifics of it, but there isn’t always a UI page that corresponds with a dialog. A lot of times ServiceNow will store the logic in a back-end XML file by the same name. If it’s working and you don’t see a UI page it’s probably back-end XML.
