Function generateFormElementsConditionallyShown

Given a form element and submission data, evaluate which elements are currently shown. The function also takes an optional errorCallback for handling errors caught during the evaluation.

Example

const formElementsConditionallyShown =
  conditionalLogicService.generateFormElementsConditionallyShown({
    submission: {
      radio: ['hide'],
      text: 'hidden text',
    },
    formElements: [
      {
        name: 'radio',
        label: 'Radio',
        type: 'radio',
        required: false,
        id: '5ef3beb8-8ac8-4c8d-9fd3-d8197113bf54',
        conditionallyShow: false,
        options: [
          {
            id: '9a44e15a-5929-419d-825e-b3dc0a29591f',
            label: 'Show',
            value: 'show',
          },
          {
            id: 'd776ed42-072c-4bf8-9879-874b2bef85d3',
            label: 'Hide',
            value: 'Hide',
          },
        ],
        readOnly: false,
        isDataLookup: false,
        isElementLookup: false,
        buttons: false,
        optionsType: 'CUSTOM',
        conditionallyShowOptions: false,
      },
      {
        name: 'text',
        label: 'Text',
        type: 'text',
        required: false,
        id: '8fbddb41-348d-494c-904b-56a2c4361f13',
        requiresAllConditionallyShowPredicates: false,
        conditionallyShow: true,
        conditionallyShowPredicates: [
          {
            elementId: '5ef3beb8-8ac8-4c8d-9fd3-d8197113bf54',
            optionIds: ['9a44e15a-5929-419d-825e-b3dc0a29591f'],
            type: 'OPTIONS',
          },
        ],
        readOnly: false,
        isDataLookup: false,
        isElementLookup: false,
      },
    ],
    parentFormElementsCtrl: undefined,
    errorCallback: (error) => {
      //do something with the error here
      console.error(error)
    },
  })
Copy

The above example returns an object like below

{
  "radio": {
    "isHidden": false,
    "type": "formElement"
  },
  "text": {
    "isHidden": true,
    "type": "formElement"
  }
}
Copy
