Change Form Header Background Color

ust a quick scripting tip today based on a solution that I helped someone with on the ServiceNow community site. The request I received was to be able to change the form header background color based on changes to values in a record. You’re probably aware that ServiceNow provides a global CSS property to set the form and list header color. This is usually one of the first things that gets customized during a deployment. The global property can be found by navigating to System Properties -> CSS, and changing the ‘Banner and list caption background color’ property.

This request required something more dynamic so that the color could change based on specific table and record values and specific changes to a specific form. In order to accomplish this, I came up with a simple client script that can be used anywhere you need it.

Changing a Number Prefix for Existing Records

had a customer ask me this morning if it was possible to change the number prefix for records in the Change Request table. Specifically, they wanted to change the prefix from the default ‘CHG’ to ‘RFC’. The answer to this question is ‘Yes’, but there are a couple of things you need to do and be careful about…especially if you’re changing the prefix in a table that has existing records using the prefix. In this post, I’ll explain how you can adjust the number prefix of a table using the ‘Number Maintenance‘ module. I’ll also show how you can use a script to adjust the number prefix on existing records.

Customizing the dirty form alert popup

I

had a colleague come to me recently for help on a client issue. The customer wanted two things; the first was to set up the capability to warn users when they were navigating away from a modified form without saving it, but to do this only on selected forms rather than globally. The second was to modify the text included in the alert dialog to be whatever they wanted. In this post I’ll explain some of the options that ServiceNow provides in this area and how you can get even more flexibility and control over this behavior through scripting.

Attach an event listener to a related list button

ecently a colleague asked me for assistance with a customer request. The requirement was to pop up an information or alert message when a user clicked the ‘Edit’ button on the ‘Affected CIs’ related list. The alert message would give them some information or a warning, allow the user to confirm, and then continue on to the edit screen. ServiceNow gives you a lot of control over the behavior of some buttons with the configuration of UI actions. There are other buttons in the system, however, that you can’t easily control…including many related list buttons. In order to meet this requirement I created an ‘onLoad’ client script to attach an event listener and onclick function to the necessary button. Read on to see how it’s done!

Automatically adjust the height of text area to fit contents

ere are a couple of script examples you might find useful. Say you’ve got a multi-line text field or variable that contains a lot of text. To save time in scrolling (or clicking the ‘+’ icon next to the field) to see all of the text you just want to auto-expand the height of the field to fit its contents based on some other client-side trigger. Here are a couple of scripts that allow you to do that.

Schedule-based Date/Time Addition

was recently asked to help a colleague figure out some date calculations based on a schedule. The requirement was to calculate a future date based on the existing value of a date/time field. I decided to document this solution (and come up with a solution for a similar problem…date addition from the current date/time based on a schedule). Working with dates and schedules can really be a pain if you don’t have good examples to work from so hopefully these help somebody at some point. Read on for the full scripts.

ere’s a quick tip for a Monday. This post comes in response to a question on the ServiceNow forums asking if it is possible to change the label of a field dynamically based on some record criteria (such as record type). It is possible, and this post will show you how it can be done.

Animate ServiceNow with jQuery and Prototype Effects!

while ago, I was trying to figure out how I could add some javascript animations and effects to a ServiceNow instance. What I really wanted was something like the jQuery Effects API but I didn’t want to have to incorporate a separate API and deal with the loading the bulk of jQuery everywhere in the instance. I knew that ServiceNow provided some limited collapse/expand effects but I was hoping for a little bit more.

I’m happy to report that I found it! Somebody smarter than me decided to convert the jQuery effects library for use with Prototype (which ships with ServiceNow) and incorporate those effects and animations directly in ServiceNow.

co-worker asked me for some help yesterday fulfilling an interesting requirement. He needed to set up a configuration item reference field or catalog variable that would display a calendar macro that, when clicked, would open a popup window containing a change calendar report for that configuration item. I figured this idea might be of use to others so I’m posting it here!

Set Default Date/Time Picker Dialog Time

ave you ever wondered how you can change the default time displayed in a Date/Time dialog? In general, the Date/Time dialog is controlled by back-end code so there’s not much you can do with it. I’ve seen this question a few times now so I decided to come up with a solution.
