What is GlideAjax in ServiceNow? GlideAjax is a class in ServiceNow which is used to execute server side code from client side. So, definition clearly says that we must define GlideAjax in client side scripts. But the Server side code which has to be executed through GlideAjax class should be defined in Script Include.

While defining GlideAjax call in client side script we have should take care of below points: We should initialize GlideAjax with name of script include which we have to use. The script includes which we will use, we should make sure that client callable checkbox must be checked. The client-side script passes parameters using GlideAjax to the Script Include.

The parameter uses naming conventions. For example, GlideAjax pass function name in parameter which it requires to execute at server end.

Some example syntax are mentioned below: ga. So here the question is, that why we execute server side code from client side? There are lot of scenario, where to validate the things we need to execute server side code from client side.

So here for validation we can get managers group name from the database or from server. So, in this scenario we execute server side code for validating the details. Different type of GlideAjax in ServiceNow with examples?

We can call execute glide ajax code in two ways synchronously and asynchronously. So, because of that user can proceed with other fields filling etc.

Synchronous Glide Ajax in ServiceNow Synchronous GlideAjax use getXMLWait function, so user cannot process with other fields filling or other fields will get freeze until the response is not received from the server.

Example of Synchronous GlideAjax ServiceNow: For example in Login window, until the username and password are not validated user cannot proceed further. In a form, if one field in dependent on another field than we can use Synchronous GlideAjax. Such as Location and Time zone. If the user selects the location, then based on location time zone will get populated.

Call Script Include from Client Script in ServiceNow using GlideAjax

So, till the time zone is loading user must wait for the same. Actually, It depends on us that for what requirement we are coding. Do we want user to proceed with other fields while process is running on or do we want user to wait until the response is received from the server?

But for normal operation always use Asynchronous GlideAjax. For better and seamless end user experience. The function is said to be callback function, when it is passed as an argument to another function so that it can be called back later. This function is used to avoid application halt while the data is being fetched from the database or server. Example is mentioned below:. I hope this ServiceNow Tutorial provide you complete understanding of glideajax in servicenow and i believe clear you all doubts you have in servicenow glideajax concept.This app is provided free of charge, with no support and I can't be held liable for anything that goes wrong in your unique instance.

I hope you get value, but please use it only at your own risk! The reason I developed this is because I had a requirement to introduce a number of different default portals with not only different branding depending on which Company the user worked for, but also to allow different user types to see different content based on Role or Group.

This table is basically a list of rules that will run in ascending order which have 2 main attributes; a A Redirect Destination of either the Platform UI or a Portal reference b A Redirect Condition consisting of a choice of which type of rule is being run along with a field value and Condition. When you create a Portal Redirect Rule, firstly set up the order that you want it to run lowest order first, highest order last.

This should work for complex dot-walks and also allow queries of field values on the related user's table. Again, this should allow some dotwalks and other capabilities that might be handy. All in all, these three query types should allow a reasonable level of flexibility in what you might want to do, but it will depend on your instance.

Remember also that because the rules run in order until they find a match, you might be able to have conflicting rules based on complex conditions I haven't done a lot of thorough testing at this stage to push the limits, but it's better than the flat, hard-coded version of SPEntryPage that ServiceNow gives you. After the user logs in, the Redirect Script include will cycle through all the rules until it finds a match. This is where the app gets a little trickier to implement.

My original intent was to have a fully scoped version of the SPEntryPage script so that all you'd need to do is create your redirect rules, then replace the glide.

Syntax to call the functions in the Script include for those who haven't dealt with scoped apps much requires the namespace of the scoped app to be appended:.

This was written in a personal instance - I may at some point replatform to a TPP developer instance to get a nicer namespace, but it's likely I'll leave it as-is. This allows you to set up a standalone portal to contain the default landing page and theme for a login attempt prior to passing a user through to whichever portal or native UI they are entitled to.

For this reason, it is generally good practice to move any complex processing, large requests more than a hundred or so recordsand multi-level dot-walking to server-side scripts such as business rules which can present the data to the client.

This can be done in a few ways, such as by using GlideAjax. It's also a good idea to utilize callback functions in almost every case where you're doing record lookups client-side. In this article, we'll go over some of the best ways to get the greatest client-side performance out of ServiceNow, by using good coding practices, callback functions, and GlideAjax to push some of the work off onto the server, rather than the client and prevent the client from having to wait around for the server to respond.

This article got a little bit away from me, and ended up being kind of enormous. Therefore, I'll include a little 'index' here, to help you navigate:. Understanding Client-Side GlideRecord. Callback Functions Asynchronous Queries. Private GlideAjax Functions. Client-Side Encoded Queries. Update : Since ServiceNow removed the ability to do synchronous GlideRecord or GlideAjax calls completelyyou might find yourself in a bind if you need to use GlideAjax or a GlideRecord query in an onSubmit client script.

It provides functions for us to interact with the database, run queries, and so on. Client scripts, are scripts that run inside the user's browser the 'client' when a page is loaded, when a form is modified, or when the form is submitted.

Client-side scripts that execute when a page loads or a field is modified, "block" the user from interacting with the page. Pro Tip : While most scripts only take microseconds or milliseconds to execute, many Client Scripts that run when the page loads should generally be changed to display Business Rules, since they prevent the browser from having to load and work with the form while the user is still waiting.

Callback functions, if you aren't familiar with them, are wondrous things. Once they 'click' in your mind and start making sense, they become the solution to a great many questions. Callback functions enable asynchronous operations such as querieswhich means queries that don't wait for the server to respond, before returning control of the browser to the user or the rest of the script s on the page.

The down-side to client scripts, is that if they don't use a callback function the user must wait for them to finish executing before they can interact with the page. Their browser effectively 'locks up' the page until all scripts are finished executing. You've probably seen the effects of this yourself when a page SEEMS to be finished loading, but its' browser icon is still "spinning", and you can't interact with it.Take control of IT chaos and transform your business.

Scripts in ServiceNow can do many, many things. Examples of things server-side scripts can do include:. Two types of server-side scripts:.

Business Rules Business Rules are server-side logic which execute when database records are queried, updated, inserted, or deleted. Business Rules respond to database interactions regardless of access method: for example, users interacting with records through forms or lists, web services, data imports configurable. The When option determines when, relative to database access, Business Rule logic executes:.

The forms shown in the graphics on this page represent a user interacting with the database by loading and saving records in a form.

Advanced Reference Qualifier Using a Script Include

Before Before Business Rules execute their logic before a database operation occurs. Use before Business Rules when field values on a record need to be modified before the database access occurs. Before Business Rules run before the database operation so no extra operations are required. For example, if you want to concatenate two fields values and write the concatenated values to the Description field. Use after Business Rules when no changes are needed to the record being accessed in the database.

For example, use an after Business Rule when updates need to be made to a record related to the record accessed. If a record has child records use an after Business Rules to propagate a change from the parent record to the children. Async Like after Business Rules, async Business Rules execute their logic after a database operation occurs. Unlike after Business Rules, async Business Rules execute asynchronously. Async Business Rules execute on a different processing thread than before or after Business Rules.

They are queued by a scheduler to be run as soon as possible. Use Async Business Rules when the logic can be executed in near real-time as opposed to real-time after Business Rules. They go in and out of the queue very quickly and can be hard to catch on the schedule.

Display Display Business Rules execute their logic when a form loads and a record is loaded from the database. They must complete execution before control of the form is given to a user. The order in which the Business Rules execute is:. Set Field Values The Set field values option allows you to set values of fields without scripting.

Values can be:. Only reference fields have the dynamic option. In the example, the Requested for value is dynamically set to the currently logged in user as determined at runtime. The Description field has the same value as the Short description field. The State field is hard coded to the value Awaiting Approval.

Add Message Use the Add message field to add a message to the top of a page.Scripts can be used in many places. The most important detail is whether the script runs on the client or the server. Can have a condition which must be true for the script to run.

Commonly used to call a Script Include. Contains scripts which can be functions or classes. These scripts run only when called by other scripts often Business Rules. Any server script which is complicated or reusable should be a Script Include especially complicated Business Rules. Creates the ability to choose a specific action such as clicking a button or a link. Defines which "right-click menu" will pop-up in which area, and the menu choices that will be available.

Contains modular, reusable components that can contain Jelly and are called by UI pages. They also contain different types of scripts and may be called multiple times on the same page. Used to create and display pages, forms, dialogs, lists and other UI components.

Can be displayed on a standalone basis, or called as a usable component, as part of a larger page. Contains client scripts stored for re-use. Only used when called from other scripts.

Business Rules

For example, a validation script can verify that the only value allowed in a specific field is an integer. Used to create or change a workflow. Scripts can be run at any point in a workflow, or different scripts can be run at different points.

Scripts also can be found inside every workflow activity and can be modified although do so with extreme caution. Table 1. Script types and where they run Script Description Runs on Access Control Determines whether access will be granted for a specified operation to a specific entity. Used for making changes to the appearance of forms, displaying different fields based on values that are entered or other custom display options.

Contains scripts which run when an event occurs, for example approval is cancelled change is approved problem is assigned. Used for importing data. UI Actions put these items on forms and lists: buttons links context menu items list choices.

Note: If you use a left-handed mouse configuration, right-click means "click the other button. Defines the behavior and visibility of fields on a form. Use UI Policies rather than client scripts whenever possible. UI Policies are always attached to one table UI Policies often have a condition which must be true in order for them to run. Access Control. Determines whether access will be granted for a specified operation to a specific entity.

Ajax Scripts. Enables the client to get data from the server to dynamically incorporate into a page without reloading the whole page. Ajax Client Scripts request that information be returned, or that action be taken, or sometimes both Ajax Server Scripts fulfill Ajax Client Script requests.

Business Rules. Customizes system behavior runs when a database action occurs query, insert, update or delete the script may run before or after the database action is performed runs as part of the database operation asynchronously at some point after the database operation on display when displaying the data in a form. Service Catalog UI policies. Defines the display of a variable set or a catalog item from the service catalog.

Client Scripts.
