g_form is used very heavily all over in ServiceNow.
As such it has a lot of documented and undocumented functions.
Below I go over all of them and how to use them.

These methods I've found in the script that dictates it's available on
the portal/mobile clients.

Mobile addDecoration

Adds an icon on a field's label. This method is available starting with
the Fuji release. Icons available
here
Adding the same item twice is prevented; however, you can add the same
icon with a different title.

 g_form.addDecoration('caller_id', 'icon-star', 'VIP');

Mobile getLabel

 if (g_user.hasRole('itil')) {
    // getLabel returns the label for the field listed
    // I'd suggest using getLabelOf as it's supported
    // both on desktop and on mobile / sp
    var oldLabel = g_form.getLabel('comments');
    g_form.setLabel('comments', oldLabel + ' (Customer visible)');
 }

Mobile hasField

 // returns true if form has 'assignment group';
 g_form.hasField('assignment_group');

Mobile removeDecoration

 // this removes a decoration
 g_form.removeDecoration('caller_id', 'icon-star', 'VIP');

Mobile setLabel

 if (g_user.hasRole('itil')) {
    var oldLabel = g_form.getLabel('comments');
    g_form.setLabel('comments', oldLabel + ' (Customer visible)');
 }

Mobile addErrorMessage

Displays an error message at the top of the form

 g_form.addErrorMessage('ERROR!');

Mobile addInfoMessage

Displays an informational message at the top of the form

 g_form.addInfoMessage('The top five fields in this form are mandatory');

Mobile addOption

Adds a choice to a choice list field If the index is not specified, the
choice is added to the end of the list.

Optional: Use the index field to specify a particular place in the list

 g_form.addOption('priority', '6', '6 - Really Low');
 g_form.addOption('priority', '2.5', '2.5 - Moderately High', 3);

Mobile clearMessages

Removes all informational and error messages from the top of the form.

Removes informational and error messages added with
g_form.addInfoMessage() and g_form.addErrorMessage().

 g_form.clearMessages();

Mobile clearOptions

Removes all options from a choice list

 g_form.clearOptions('priority');

Mobile clearValue

Removes any value(s) from the specified field

g_form.clearValue('short_desciption');

of the UI Action clicked Note: not available to Wizard Client Scripts

 function onSubmit() {
   var action = g_form.getActionName();
   console.log('You pressed ' + action);
 }

Mobile getBooleanValue

Returns false if the field's value is false or undefined, otherwise true
is returned. Useful with checkbox fields Returns true when the checkbox
is checked

 // Returns false if the field value is false or undefined;
 // otherwise returns true.
 var active = g_form.getBooleanValue('active');

Mobile getDecimalValue

 function onChange(control, oldValue, newValue, isLoading) {
   console.log(g_form.getDecimalValue('percent_complete'));
 }

Mobile getDisplayValue

 g_form.getDisplayValue();//returns record displayvalue, not field displayvalue
 g_form.getDispalyValue('caller_id');//returns record displayvalue, not field displayvalue

Mobile getEncodedRecord

 // returns '' or _options.encodedRecord normally that's null
 // I don't see when that would be set to something else.  Doesn't
 // seem to work on catalog items, or on form's in service portal.
 g_form.getEncodedRecord();

}

Desktop isLiveUpdating

Desktop isMandatory

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 UI16 with live forms enabled.

  g_form.isLiveUpdating();

Desktop isNewRecord

Returns true if the record has never been saved Returns false if the
record has been saved

Desktop setDisplay

Displays the field if true. Hides the field if false. This method cannot
hide mandatory fields with no value. If the field is hidden, the space
is used to display other items

  var bool = true;
  g_form.setDisplay('caller_id', true);

Desktop setLabelOf

Sets the plain text value of the field label. This method is available
starting with the Fuji release

if (g_user.hasRole('itil')) {
  var oldLabel = g_form.getLabelOf('comments');
  g_form.setLabelOf('comments', oldLabel + ' (Customer visible)');
}

Desktop setMandatory

Makes the field required if true. Makes the field optional if false.
Best Practice: Use UI Policy rather than this method whenever possible

g_form.setMandatory('quantity',true);// changes field to required or not

Desktop setReadOnly

Makes the field read-only if true Makes the field editable if false.
Note: Both setReadOnly and setReadonly are functional. Best Practice:
Use UI Policy rather than this method whenever possible

g_form.setValue('milestone', milestone);
g_form.setReadonly('end_date', milestone);
g_form.setReadonly('duration', milestone);

Desktop setSectionDisplay

Shows or hides a section Works in both tab and flat modes. This method
is available starting with the Fuji release

function onChange(control, oldValue, newValue, isLoading) {

   var sections = g_form.getSections();
   if (newValue == '2') {

   } else {
      g_form.setSectionDisplay(sections[1], true);
   }
}

Desktop setValue

Sets the value and the display value of a field Will display value if
there is no displayValue

g_form.setValue('quantity','10');// sets the value to 10

Desktop setVisible

Displays the field if true. Hides the field if false. If the field is
hidden, the space is left blank. This method cannot hide mandatory
fields with no value

function onLoad() {
  g_form.setVisible('u_environment', false);
}

Desktop showErrorBox

Displays an error message under the specified form field (either a
control object or the name of the field). If the control or field is
currently scrolled off the screen, it will be scrolled to. A global
property (glide.ui.scroll_to_message_field) is available that
controls automatic message scrolling when the form field is offscreen
(scrolls the form to the control or field). The showFieldMsg() method is
a similar method that requires a 'type' parameter

var scroll = true;
g_form.showErrorBox('caller_id','message',scroll)

Desktop showFieldMsg

Displays either an informational or error message under the specified
form field (either a control object or the name of the field). Type may
be either 'info' or 'error.' If the control or field is currently
scrolled off the screen, it will be scrolled to. A global property
(glide.ui.scroll_to_message_field) is available that controls
automatic message scrolling when the form field is offscreen (scrolls
the form to the control or field)

 // parameters are;
 // field, string, info||error, scrollToField
 g_form.showFieldMsg('stage', 'text info', 'info', false);
 g_form.showFieldMsg('stage', 'text erro', 'error', false);

  } else if(newValue == 'show') {
    g_form.showRelatedList('sc_request');
  } else if(newValue == 'hide all'){
    g_form.hideRelatedLists();
  } else if(newValue == 'show all'){
    g_form.showRelatedLists();
  }
}

Desktop showRelatedLists

Displays all related lists on the form

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
  if (isLoading || newValue === '') {
    return;
  }
  if(newValue == 'hide'){
    g_form.hideRelatedList('sc_request');
  } else if(newValue == 'show') {
    g_form.showRelatedList('sc_request');

    g_form.hideRelatedLists();
