Script

...

Includes are used to store JavaScript functions and classes that will execute on the server. Script

...

Includes generally

...

specify either an object class or a function.

...

Tip

Role required: admin.

...

Creating a script include

...

A script include has a name, a description, and a script itself. Also, it is possible to specify

...

options active or client-callable.

...

To create a new script include, please complete the following steps:

  1. Navigate

...

  1. to System Settings → ScriptIncludes.
  2. Click New and fill in the fields.
  3. Click Save or Save and Exit to apply changes.

...

Script Include form fields

FieldMandatoryDescription
NameYScript include name.

...

 Should match with the class name declared in the script field. Also, script include name should be unique and can not contain spaces.
DescriptionNShort action description.
Active

...


Select this checkbox to activate this script. When selected, the script will execute when called; otherwise, it will not execute.
Client

...

Callable
Select this checkbox to make this script available to call on the client-side scripts.
Disable ACL Check
Select this checkbox to let this script include do go through an ACL check when executed within Client Scripts.
ScriptY

Define the server-side script to run when called from other scripts.

Note

When invoking script includes in other server-side scripts, please use the ss.importIncludeScript method of the SimpleSystem class like shown on the example below:

Code Block
languagejs
themeEclipse
linenumberstrue
ss.importIncludeScript('EmailHelper');
const helper = new EmailHelper();

Otherwise, the script would be unavailable.

...


Practical case

You can

...

use client callable script includes in case

...

you need to use server-side methods on the client-side. For more clarity, let us consider two simple examples of calling a script include from:

  • a client-side
  • a server-side

...

Using client callable script include on forms

A practical case is a calculation of the time period between two specified values using a specific schedule.

For this, let us create script include with parameters like shown below:

NameDurationCalculator
Activetrue
Client Callabletrue
Script

Enter a script from the code example below:

Code Block
languagejs
themeEclipse
title

...

Client callable script include

...

linenumberstrue
ss.importIncludeScript('AbstractAjaxProcessor');

...


var DurationCalculator = Class.create();
DurationCalculator.prototype = Object.extendsObject(AbstractAjaxProcessor, {

...

    getDuration() {

...

        const start =

...

 new SimpleDateTime(this.getParameter('sysparm_start'));

...

        const end =

...

 new SimpleDateTime(this.getParameter('sysparm_end'));

...

        const scheduleID =

...

 this.getParameter('sysparm_schedule');

...

        const schedule =

...

 new SimpleSchedule(scheduleID);

...

        // value that would be passed to client-side

...


        return schedule.duration(start, end).getDurationSeconds() * 1000;
    }
});

...


Note

When you call values passing from the client-side, use this.getParameter like shown in a code example above to get the sysparm_ parameter value.


On the client-side, we use SimpleAjax:

  1. Create a SimpleAjax instance.
  2. Transfer the called method name using the reserved parameter sysparm_name.
  3. Transfer values from a form using the sysparm_start, sysparm_end, sysparm_schedule parameters.
  4. Call an include script using the getXML(callback) method.
    1. Process its response in the callback-function listed below.
  5. The answer variable will contain value return by the getDuration() method.

linenumberstrue

...

if (s_form.getValue('start') &&

...

 s_form.getValue('end') &&

...

 s_form.getValue('schedule_id')) {

...


    const calculate =

...

 new SimpleAjax('DurationCalculator');

...

 // call script include

...

    calculate.addParam('sysparm_name',

...

 'getDuration'); // call method

...

    calculate.addParam('sysparm_start', s_form.getValue('start')); // pass param

...

    calculate.addParam('sysparm_end', s_form.getValue('end')); // pass param

...

    calculate.addParam('sysparm_schedule', s_form.getValue('schedule_id')); // pass param

...

    calculate.getXML(callback);

...


    function callback(response) {
    	// value received from server-side
        const answer = response.responseXML.documentElement.getAttribute('answer');
        s_form.setValue('duration', answer);
    }
}

Using client callable script include on lists

Another example is the calculation of list items after filtering.

For this, let us create script include with parameters like shown below:

NamegetListItemsCount
Activetrue
Client Callabletrue
Script

Enter a script from the code example below:

Code Block
languagejs
themeEclipse
titleClient callable script include
linenumberstrue
ss.importIncludeScript('AbstractAjaxProcessor');
 
var getListItemsCount = Class.create();
getListItemsCount.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    
  getCount() {
    const table_name = this.getParameter('sysparm_table_name');
    const condition = this.getParameter('sysparm_condition_query');
    const list = new SimpleRecord(table_name);
    list.addEncodedQuery(condition);
    list.selectAttributes('sys_id');
    list.query();
    // value that would be passed to client-side
    return list.getRowCount();
  }
  });

Note

When you call values passing from the client-side, use this.getParameter like shown in a code example above to get the sysparm_ parameter value.


The client-side code will be the following:

Code Block
languagejs
themeEclipse
titleUsing script include on the client-side
linenumberstrue
const queryString = window.location.search;
const urlParams = new URLSearchParams(queryString);

const sAjax = new SimpleAjax('getListItemsCount'); // initialize script include
sAjax.addParam('sysparm_name', 'getCount'); // call method
sAjax.addParam('sysparm_table_name', s_list.getTablesName()[0]); // pass param
sAjax.addParam('sysparm_condition_query', urlParams.get('condition') || '()'); // pass param
sAjax.getXML(callback);

function callback(response) {
    // value received from server-side

...

    const answer = response.responseXML.documentElement.getAttribute('answer');
    s_list.clearMessages();
    s_list.addInfoMessage(`List items count: ${answer}`, 2000);
}
