how to get existing fieldGroup ID in suitescript

AI generated answer (using internal Slack threads):

In SuiteScript, there isn't a direct way to get the ID of an existing field group. However, there are a few workarounds you can use: 1. Using `form.insertField()`: This method allows you to insert a field at a specific location on the form. The inserted field will inherit the field group of the location where it's inserted. Here's an example:

javascript
form.insertField({
    field: yourField,
    nextfield: 'existingFieldInDesiredFieldGroup'
});

In this example,

yourField

is the field you're inserting, and

existingFieldInDesiredFieldGroup

is an existing field in the field group where you want to insert your field. The new field will be inserted before the specified

nextfield

. 2. Inspecting the Form's HTML: You can inspect the HTML of the form to find the

id

attribute of the

<td>

tag that contains the Field Group. The

id

attribute will have the Field Group's script ID, prefixed with

fg_

, e.g.

fg_custpage_grp_prompt

. However, this method is more of a hack and may not be reliable. Please note that these methods are workarounds and may not work in all situations. Also, the behavior of

form.insertField()

can be affected by the layout type and break type of the fields. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
