# GlideForm \(g\_form\) - Client

The GlideForm API provides methods to customize forms.

Only use GlideForm methods on the client. You can use these methods to make custom changes to the form view of records. All validation of examples was done using client scripts.

You can also use some of these methods in other client scripts \(such as Catalog Client Scripts or Wizard Client Scripts\), but you must first test this to determine whether they will work as expected.

**Note:** The methods getControl\(\), getHelpTextControl\(\), getElement\(\), and getFormElement\(\) are deprecated for mobile devices. For information on using GlideForm for mobile, see [Mobile Client GlideForm \(g\_form\) Scripting and Migration](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/scripts/r_MobilePlatformMigrationImpacts.md).

There is no constructor for the GlideForm class. Access GlideForm methods using the `g_form` global object.

**Parent Topic:**[Client API reference](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/api-client.md)

## GlideForm - addDecoration\(String fieldName, String icon, String title\)

Adds an icon on a field's label.

Adding the same item twice is prevented; however, you can add the same icon with a different title.

## GlideForm - getControl\(String fieldName\)

Returns the HTML element for the specified field.

Compound fields may contain several HTML elements. This method is generally not necessary as there are built-in methods that use the fields on a form.

If the field is a reference field and the control is a choice list, getControl\(\) may not return a control as expected. In this case, use `sys_select.<table name>.<field name>`.

This method is not available in mobile scripts or Service Portal scripts.

const options = g_form.getOptions('priority');
if (options) {
  console.log('Selected:', options.selected);
  options.getAvailable('high').then(available => {
    console.log('Available matching "high":', available);
  });
}
```

## GlideForm - getReference\(String fieldName, Function callBack\)

Returns the GlideRecord for a specified field.

If a callback function is present, this routine runs asynchronously. The browser \(and script\) processing continues normally until the server returns the reference value, at which time, the callback function is invoked. If a callback function is not present, this routine runs synchronously and processing halts \(causing the browser to appear to hang\) while waiting on a server response.

**Important:** It is strongly recommended that you use a callback function.

Callback function support for ServiceCatalogForm.getReference is available.

**Note:** Using this method requires a call to the server which requires additional time and may introduce latency to your page. Use this method with caution. For additional information, see [Client script design and processing](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/scripts/client-script-best-practices.md).

```

## GlideForm - getRelatedListNames\(\)

Returns an array of related list names from the current form.

|Name|Type|Description|
|----|----|-----------|
|None| | |

|Type|Description|
|----|-----------|
|Array of Strings|List of related list names from the current form. The related list names are listed in the order in which they appear on the form.|

```
var listNames = g_form.getRelatedListNames();

for (var i = 0; i < listNames.length; i++) {  
  this.showRelatedList(listNames[i]);

   // and hid a section when the "state" field was changed
   var sections = g_form.getSections();
   if (newValue == '2') {
      g_form.setSectionDisplay(sections[1], false);
   } else {
      g_form.setSectionDisplay(sections[1], true);
   }
}
```

## GlideForm - getTableName\(\)

Returns the name of the table to which this record belongs.

On the server side, the table for the current record can be retrieved with current.sys\_class\_name or current.getTableName\(\).

|Name|Type|Description|
|----|----|-----------|
|None| | |

|Type|Description|
|----|-----------|
|String|Name of the table.|

function onLoad() {
   var incSysid = g_form.getUniqueValue();
   alert(incSysid);
}
```

## GlideForm - getValue\(String fieldName\)

Returns the value of the specified form field.

This method also supports getting values from a multi-row variable set \(MRVS\). To obtain data from fields within an MRVS, you must first use `JSON.parse(getValue('<mrvs_field_name>') || '[]')` to obtain the MRVS array, and then use indexing to access the fields within the row objects. For more details, see the code example below.

|Name|Type|Description|
|----|----|-----------|
|fieldName|String|Name of the field whose value to return.|

|Type|Description|
|----|-----------|
|String|Value of the specified field.|

The following example shows how to get the short description from the current form.

```
function onChange(control, oldValue, newValue, isLoading) {
   alert(g_form.getValue('short_description'));
}
```

The following example shows how to get values from an MRVS. In this example, salaries are being managed through the Service Catalog. The client script searches all rows within the MRVS for the value entered in the **Job title** and then updates the matching entries within the MRVS with what is entered in the **Salary** field. The MRVS is named "variable\_set\_1" and contains the following fields within each row object: Employee name \[employee\_name\], Job title \[employee\_job\_title\], and Salary \[employee\_salary\]. In addition, the Catalog Item contains: Job title \[job\_title\] and Salary \[salary\].

```
function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
 
// Get the MRVS
var vs1 = g_form.getValue('variable_set_1') || '[]';
var multiRowVariableSet = JSON.parse(vs1);
 
for (var i = 0; i < multiRowVariableSet.length; i++) {
// Check if the entered job title matches the title in the current MRVS row
  if (multiRowVariableSet[i].employee_job_title == g_form.getValue("job_title")){
    // Update the value of a matching field with the new salary
    multiRowVariableSet[i].employee_salary = newValue;
  }
}
 
// Update the MRVS
g_form.setValue('variable_set_1', JSON.stringify(multiRowVariableSet));
}
```

Use the [GlideForm - showFieldMsg\(String field, String message, String type\)](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/c_GlideFormAPI.md) or [GlideForm - showFieldMsg\(String field, String message, String type, Boolean scrollForm\)](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/c_GlideFormAPI.md) methods to display messages on a form.

For example, the following code snippet shows how to display two messages on the `work_notes` field of a form and then hide the first message:

```
g_form.showFieldMsg('work_notes', 'First message', "error");
g_form.showFieldMsg('work_notes', 'Second message', "error");
g_form.hideFieldMsg('work_notes', false); // This call hides the 'First message'

## GlideForm - isLiveUpdating\(\)

Returns true while a live update is being done on the record the form is showing.

This can be used in an onChange\(\) client script to determine if a change to the record is because of a live update from another session. The client script can then decide what action to take, or not to take. This applies to systems using Core UI with live forms enabled.

## GlideForm - isMandatory\(String fieldName\)

Returns true if the field is mandatory.

Mandatory fields are visually distinguished by an asterisk next to the field label. The asterisk is red if the field is empty, and black if the field is not empty. The system displays a validation message if a user attempts to save or submit the form without completing those fields. For more information, see [Form fields](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/platform-user-interface/c_FormFields.md).

```

## GlideForm - onUserChangeValue\(Function fn\)

Registers a custom event listener that detects when any field in the current form is modified by a user.

When a form field is modified, the event listener calls the function that is passed in when the listener is initially registered. This listener is only triggered when a user makes a change to a field on the form. Changes from client scripts, UI policies, or any other non-user interactions, do not trigger the listener.

**Note:** This method does not work for journal fields or Service Catalog items in the classic environment.

Whenever possible, use a UI policy instead of this method.

To make a mandatory field read-only, you must first remove the mandatory requirement for that field by using the setMandatory\(\) method.

Once you set a field to read-only, you cannot use the [setValue\(\)](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/c_GlideFormAPI.md) method to update the value of that field. If you need to set the value in this way, you must set the **readOnly** value to `false.`

## GlideForm - setRelatedLinksDisplay\(Boolean display\)

Show or hide the Related Links section in the form UI using Boolean values.

[GlideForm - hideRelatedLinks\(\)](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/c_GlideFormAPI.md) hides related link UI Actions on the form, while [GlideForm - showRelatedLinks\(\)](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/c_GlideFormAPI.md) shows them. The g\_form.setRelatedLinksDisplay\(boolean: display\) method, however, can be used to either show or hide related links with more flexibility in your scripts.

## GlideForm - setValue\(String fieldName, String value, String displayValue\)

Sets the value of a specified form field to the specified value or the value of a specified display value in a reference record.

To improve performance by preventing a round trip when setting the value for a reference field, use this method, not setValue\(fieldName, value\). When setting multiple reference values for a list collector field, pass arrays in the **value** and **displayValue** parameters.

This method also supports setting values in a multi-row variable set \(MRVS\). You must first use `JSON.parse(getValue('<mrvs_field_name>'))` to obtain the MRVS array and then use indexing to update the fields within the row objects. Once all values are updated in the MRVS, use the setValue\(\) method to save the updated MRVS array. For more details, see the code example below.

**Note:** This method can't be used to update fields set to strict read only. If this method is called on strict read only fields, the field isn't updated and a warning is logged in the browser console. For more information, see [Configuring read-only security options](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/platform-administration/read-only-option.md).

**Note:** This method can't be used to update fields set to strict read only. If this method is called on strict read only fields, the field isn't updated and a warning is logged in the browser console. For more information, see [Configuring read-only security options](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/platform-administration/read-only-option.md).

**Note:** The method setValue\(\) can cause a stack overflow when used in an `onchange` client script. This is because every time the value is set, it will register as a change, which may re-trigger the OnChange client script. To prevent this, perform a check that will validate that the new value will be different from the old value. For example, before performing `setValue(shortDesc, newValue.toUpperCase());`, validate that the short description is not already uppercase. This will prevent the client script from applying the toUpperCase\(\) more than once.

The following example shows how to set the short description in the current form.

```
g_form.setValue('short_description', 'replace this with appropriate text');
```

The following example shows how to set values in an MRVS. In this example, salaries are being managed through the Service Catalog. The client script searches all rows within the MRVS for the value entered in the **Job title** and then updates the matching entries within the MRVS with what is entered in the **Salary** field. The MRVS is named "variable\_set\_1" and contains the following fields within each row object: Employee name \[employee\_name\], Job title \[employee\_job\_title\], and Salary \[employee\_salary\]. In addition, the Catalog Item contains: Job title \[job\_title\] and Salary \[salary\].

```
function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}

// Get the MRVS
var multiRowVariableSet = JSON.parse(g_form.getValue('variable_set_1'));

for (var i = 0; i < multiRowVariableSet.length; i++) {
// Check if the entered job title matches the title in the current MRVS row
  if (multiRowVariableSet[i].employee_job_title == g_form.getValue("job_title")){
    // Update the value of a matching field with the new salary
    multiRowVariableSet[i].employee_salary = newValue;
  }
}

// Update the MRVS
g_form.setValue('variable_set_1', JSON.stringify(multiRowVariableSet));
}
```

This example shows passing the sys\_id of the reference record that contains the userName field to use to update the **assigned\_to** form field.

```
g_form.setValue('assigned_to', userSysID, userName);
```

This example shows passing an array of reference record sys\_ids and an array of corresponding display value names to use to update the form fields in the GlideList **glide-list\_field\_name**.

```
g_form.setValue('glide-list_field_name', sysIDArray, displayNameArray);
```

## GlideForm - setVariablesReadOnly\(Boolean isReadOnly\)

Makes a Service Catalog variable editor read only.

**Note:** This method is only applicable to Service Catalog variable editors in the core UI. This method is not supported in the Service Catalog form.

The method must be placed in the client script of the table in which the variable editor is added, such as Requested Item \[sc\_req\_item\], Incident \[incident\], and so on. To set variables to read only in other tables, use the [setReadOnly\(\)](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/c_GlideFormAPI.md) method.

See also: [Service Catalog variable editors](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/servicenow-platform/service-catalog-variable-editor.md)

Displays a message under the specified form field \(either a control object or the name of the field\). If the control or field is off the screen, the method automatically scrolls the form to that field.

A global property \(glide.ui.scroll\_to\_message\_field\) is available that controls automatic message scrolling when the form field is off screen \(scrolls the form to the control or field\).

The showErrorBox\(\) method is a shorthand method that does not require the type parameter.

**Note:** This method does not work with the **journal\_field** type field in Core UI.

## GlideForm - toggleAnnotations\(\)

Hides or shows all annotations on the form.

[Annotations](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/platform-administration/configure-form-layout.md) are visual separators between form elements, or blocks of colored text used to highlight form elements. If annotations are visible on the form, calling toggleAnnotations\(\) hides them. Similarly if annotations are hidden on the form, calling this method displays them.
