Rather than use JavaScript alertfor a cleaner look, you can display an error on the form itself. The methods showFieldMsg and hideFieldMsg can be used to display a message just below the field itself. This example demonstrates how to modify a GlideDateTime field value using a script.

Global variables are available to all business rules. Often you may need to provide users with a way to specify when a task or process is due. Using the DurationCalculator script include, you can calculate the due date, using either a simple duration or relative duration. How much work is required to complete a task can be expressed as a "relative duration". Typically, setting a due date requires that you calculate the actual work time required for completion rather than the total time that elapses until the due date.We are experimenting with new training content delivery methods.

This tutorial blog post is one of those experiments. We are very interested in your feedback. Please let us know what you think about this format and the content in the comments below. Scripts - Background was this magical place in the platform where you could run any server-side script. It became my testing ground for any server-side method I wanted to learn about or new script I wanted to test because I did not need to configure When to run logic around it like a Business Rule.

Running a script in Scripts - Background was as easy as putting a script in the field and clicking the Run script button.

In this post, you learn how to work with Scripts - Background to add some demo data. You also learn how to work with the rollback capability to remove the demo data.

Execute in sandbox? Refer to the documentation on The script sandbox property for details on what methods are restricted. Executing in sandbox can prevent potentially harmful methods from running, but could prevent the script from its intended purpose. This example shows the messages logged when insert methods are run in sandbox. Cancel after 4 hours : Cancel long running scripts after 4 hours. Keep this selected unless you are sure your script needs more time. Even then, you should consider breaking up the work into smaller chunks.

In this section of the tutorial, you run a script in Scripts - Background to create some sample user records. Copy this script and paste it into the Run Script JavaScript executed on server field. If the Record for rollback? Access the Script Execution History from the Scripts - Background results by clicking available here in the Script execution history and recovery available here message.

Confirm the rollback. After that, the execution history is no longer available to view or roll back. Did you do the hands-on exercise in this blog? Click here to let us know!

What I do want to address is the topic of Advanced Reference Qualifiers…specifically how to leverage a Script Include instead of a global Business Rule to run your qualifier script.

Up until recently, the only way to get Advanced Reference Qualifiers to work was to create a global business rule to run the qualifier script. The best practice guidance for advanced reference qualifiers should be to use a Script Include rather than a global Business Rule to run the qualifier script. Using a Script Include means that the script only gets loaded and used when you actually need to use it! The other piece is obviously the Script Include.

Since Script Includes now allow you to use On-Demand functions, your script is identical to the one you would use in a global business rule.

Script Includes can be a single function, too. That would reduce the complexity of this a bit. Is it possible that i can dynimically change reference table on a field based on value in the another field? A is of type string. B is of type reference.

Can I change reference table on B based on value in A? I am using a Script Include as a reference qualifier, but it is behaving rather strangely. The reference field filters Business Services related to the company of the caller, I created a m2m table with a related list on both Company as well as Business Services.

The GlideAjax class allows the execution of server-side code from the client. GlideAjax calls pass parameters to the script includes, and, using naming conventions, allows the use of these parameters.

For additional information on GlideAjaxrefer to GlideAjax in the development portal. There are two parts to the asynchronous GlideAjax script: client-side and server-side code. This code runs on the client the web browser.

Create a client script as normal. This sends the parameters to server, which then does the processing. So that the client does not wait for the result, a callback function is used to return the result, passed to the getXML function.

In this case it is called HelloWorldParse. Since the response is an XML document we are not limited to returning a single answer value. Here is a more complex example returning multiple XML nodes and attributes.

Use synchronous when your script cannot continue without the GlideAjax response. This stops the session until the response is received.

If your use case demands that no further processing can occur until the GlideAjax response has been received, you can use getXMLWait. However, because this will slow down your code and lock the user session until the response is received, it is generally recommended that you use getXML with a callback function.

Provides helper functions for Ajax clients to generate Choice Lists and retrieve displayed values from a choice list. Use this script include wherever your need to generate choice lists or retrieve a value from an Ajax client.

Note: This functionality requires a knowledge of JavaScript. Hello World: Returning a value from the server Example: Client side This code runs on the client the web browser. The getXMLWait function does not need a separate callback function, but this will block the client. If the client-server communication takes a long time for example on slow networksthe application will seem unresponsive and slow.

An example of getXMLWait is in the following section. Example: Server side The server-side code for the above function.Create script includes to store JavaScript functions and classes for use by server scripts. Each script include defines either an object class or a function. Consider using script includes instead of global business rules because script includes are only loaded on request. Script includes have a name, description and script. They also specify whether they are active or not, and whether they can be called from a client script.

The script must define a single JavaScript class or a global function. The class or function name must match the Name field. You can call existing script includes from a script. To create an entirely new script include, you can follow the format of any of the existing script includes. In the example, the name of your Script Include is 'NewInclude' and there is a single function called 'myFunction.

When you create a new script include and give it a name, the system provides you a code snippet with the class and prototype set up properly. The privacy setting for a client-callable script-include can be public or private.

Most client-callable script-includes are marked private by default. The private privacy-setting means that guests who access public pages cannot access the client-callable script-include.

A private script cannot be executed by a non-logged-in user. A public privacy-setting means that the client script can be executed by non-logged-in users that create an appropriate HTTP request. This can create a security problem if the client script provides confidential information. To provide further control over all client-callable script includes, administrators can add the property glide.

This property changes the visibility of client-callable script includes by making them all public or private.

Configure the property as follows:. Change the privacy setting for a single client-callable script include by adding the isPublic function. The isPublic setting takes precedence over the glide. For example, if the property is set to false making all client-callable script-includes private, and a script sets isPublic to true, the script is public.

To change the privacy for a single client-callable script include, add the following method to the script include:.

Script includes are used to store JavaScript that runs on the server. Table 1. Script include form Field Description Name The name of the script include.

If you are defining a class, this must match the name of the class, prototype, and type. If you are using a classless on-demand script include, the name must match the function name. Application The application where this script include resides.UI scripts provide a way to package client-side JavaScript into a reusable form, similar to how script includes store server-side JavaScript. Administrators can create UI scripts and run them from client scripts and other client-side script objects and from HTML code.

You can create a UI script and designate it as global, which makes the script available on any form in the system. You cannot create a global UI script in a scoped application. You can mark a UI script as Global to make it available on any form in the system.
