CI UI Macro Actions for the Affected CIs List

he ability to associate Affected Configuration Items against a task is one of the most basic pieces of the various task forms in ServiceNow. ServiceNow gives you the ‘Configuration Item’ field to associate a single CI and the ‘Affected CIs’ related list in the event that your task needs to be associated to multiple CIs. I’ve written before about the benefits of tracking all of this information in one place to simplify reporting and usage requirements. During an onsite visit with a customer this week I noticed another opportunity to improve the functionality of the ‘Affected CIs’ related list. It would be very useful to be able to right-click items in the ‘Affected CIs’ related list and show a BSM Map or associated tasks just like you can do for the ‘Configuration Item’ field UI Macro icons. This post will show you how you can set these list context UI Actions up in your instances.

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.

Customizing the dirty form alert popup

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.

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.

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.

Hiding Related Lists and Embedded Lists

I

just saw a question on the ServiceNow forums asking how you could show and hide an embedded related list on a form. I just created some client scripts to accomplish this task so I figured I would share them here. I’ll also review the methods and limitations for showing and hiding standard related lists using client scripting.
