TEnum

Category (enumeration)

Manually creating TEnum is typically not required. Options are generated automatically from the field settings and passed through EnumField.variants. When working with a form, you can temporarily add options to the EnumField.data.variants property via script. Such options are displayed in the UI and can be used during the current form session. After the page is refreshed, they are not saved; however, the selected values remain available in the context of the current form instance. Where TEnum appears:

  • as an available option — in EnumField.variants and Context.fields.<field>.data.variants;
  • as a selected value — in Context.data.<field> (single: TEnum<T>; multiple: TEnum<T>[]).

code

code: T

Value’s code.

It is set once and used in the logic and comparison. Generated automatically from the name of the option or specified manually. Code transformation rules:

  • Converted to lowercase.
  • Sapces are replaced with underscore (_).
  • Hyphen (-) is preserved.
  • Most special symbols are replaced with underscore (_).
  • Digits can be used. Usage examples:
  • Business-process — bisness-process;
  • Client Type — client_type;
  • Type#1 — type_1;
  • Orders v2.0 — orders_v2_0. Usage examples: 
    //  Getting an option by its code 
const dict = Context.fields.category.variants;  
// Codes with symbols invalid for JS identifier are specified only in  square brackets 
const vNum   = dict['1n'];           // Starts with a digit  
const vDash  = dict['order-type'];   // Includes a hyphen 
// Valid  identifier is specified via a dot or in square brackets 
const v_Ok1 =  dict.code1; 
const v_Ok2 = dict['code1']; 
// Setting selection for the  Catgeory type field (One) 
Context.data.category = v_Ok1; 
// Setting  selection for the Category type field (Multiple)  
Context.data.category_multi = [v_Ok1, vDash].filter(Boolean); 
// Adding  available options to the interface using `data.variants` 
// Temporary  options available only in the current form for testing or single actions  
Context.fields.category.data.variants.push ({ code: 'temp_one', name: 'Temp ONE' });  
Context.fields.category.data.variants.push ({ code: 'temp_two', name: 'Temp TWO' }); 
// Gettings codes of selected  values for the Category type field (Multiple) 
const selectedCodes: string[]  = (Context.data.category_multi ?? []).map(v => v.code); 
// Getting codes of  available options 
const availableCodes: string[] =  Context.fields.category.data.variants.map(v => v.code); 
// Comparing by a  code 
if (v_Ok1.code === 'code1') { 
// ... 
} 
// Displaying the name of  the option 
console.log(v_Ok1.name);

name

name: string
