    Class SingleSelectField

    A [[Field]] type that allows a single value from a limited, pre-defined input. The possible input values are a list of [[OptionItem]]s (aka Option List).

    Say you want the user to select a month. There are only 12 months in a year, and you know all of them already. Making this a [[SingleSelectField]] instead of a [[TextField]] will greatly improve the quality of the inputted data.

    Methods

    • Returns an array of all active [[OptionItem]]s for this field.

      Returns EList<OptionItem>

      // get the CSS classes of all the active OptionItems
      const activeClasses = field.activeOptions().map(op => [op, op.cssClass()])
      explore example
      [[OptionItem.cssClass]]

    • Adds the key-value pair to the AltIds of this object. This will overwrite any existing value for the key on any object that has the same classId without warning you, so use this with caution.

      Parameters

      • key: string
      • value: string

      Returns void

    • Returns an array of all possible [[OptionItem]]s for this field, active, disabled, locked, and obsolete.

      Returns EList<OptionItem>

      // get the stati of all the OptionItems
      const statuses = field.allOptions().map(op => [op, op.status()]);
      explore example
      [[OptionItem.status]]```javascript // get an option by ID and set it field.allOptions().filter(op => op.id().toString() === id)[0].selected(true); ``` ```javascript // get an object of options indexed by ID const optionsById = Object.fromEntries(field.allOptions().map(op => [op.id().toString(), op])); ```

    • An object of alternate ids for this object, with values as [[AltId]]

      Returns { [name: string]: AltId<SingleSelectField> }

      // you've marked certain forms with the FID of deprecated and want to filter for those
      const warningMessage = baseObject.altIdsObject().FID.value().includes('deprecated') && 'Please use a different form';

    • An object of alternate ids for this object, with values as strings

      Returns { [name: string]: string }

      // you've marked certain forms with the FID of deprecated and want to filter for those
      const warningMessage = baseObject.altIds().FID.includes('deprecated') && 'Please use a different form';

    • An array of alternate ids for this object.

      Returns EList<SingleSelectField>

      // you've marked certain forms with the FID of deprecated and want to filter for those
      const warningMessage = baseObject.altIds().FID.includes('deprecated') && 'Please use a different form';

    • Same as calling optAncestor(var).orElse(null)

      Type Parameters

      Parameters

      • classType: string | number

      Returns B

    • If this object is a Collection it returns it as an array. The majority of objects in the system are Collections. For most objects, this is the same as calling [[children]].

      Returns EList<BaseObject<any>>

      const ids = obj.asArray().map(ob => ob);

    • Get the children of the object. This retrieval goes one level deep.

      Parameters

      • OptionalclassType: string | number

      Returns EList<BaseObject<any>>

      const childrenNames = obj.children().map(child => child.displayName());

    • Sets all options to unchecked.

      Returns void

      // deselect all OptionItems
      selectField.clear();

    • The "created at" timestamp of this object.

      Returns Instant

      const createdAt = `<div class="created-at">${baseObject.created()}</div>`;

    • The creator of this object.

      Returns User

      alert(`Guess who created this. It was ${baseObject.creator().fullName()}. They are to blame.`);

    • The deleted children of this object. Only looks one level deep. E.g. a form's deleted children could include fields and form entries. A folder's deleted children could include folders, forms, and formulas, but not any of those forms' entries.

      Returns EList<BaseObject<any>>

      const deleted = baseObject.deletedChildren();

    • Returns a delete URL for this object, else a blank string. Following the URL will delete the object, so proceed with caution.

      Returns string

      const deleteBtn = `<button data-href="${baseObject.deleteUrl()}">Go to ${baseObject.displayName()}</button>;

    • Returns an array of all disabled [[OptionItem]]s for this field. A disabled [[OptionItem]] will show up on a form, but it won't be selectable.

      Returns EList<OptionItem>

      // get the indexes of all the disabled OptionItems
      const disabledIndexes = field.disabledOptions().map(op => [op, op.index()])
      explore example
      [[OptionItem.index]]

    • The default display name of this object. For the most part, this is the same as calling toString(), which is the same as inserting the object into a string.

      Returns string

      The following assumes you have already aggregated a selection of baseObjects into an array

      const displayNames = [];
      for (const o of baseObjects) displayNames.push(o.displayName());
      const namesList = `<ul><li>${displayNames.join('</li><li>')}</li></ul>`;

    • Sets the Display Name.

      Parameters

      • name: string

      Returns void

    • Returns this field's [[FormMetaData]] object.

      Returns FormMetaData

      const form = firstName.form();
      const fieldNames = [];
      for (field in form) fieldNames.push(form[field].displayName());

    • Gets an array of all the object's ancestors.

      Returns EList<BaseObject<any>>

      const numberOfAncestors = obj.getAncestors().length;

      Returns Id<SingleSelectField>


      const displayDiv = `<div class="object-card" id="${baseObject.id()}">

      </div>;

      const isLocked = baseObject.isLocked();

    • Returns whether the field is multi-select.

      Returns boolean

      // get selected export values without knowing if it's single or multi
      const selectedExport = field.isMultiSelect() ?
        field.selectedExportValues() : field.optSelected().exportValue();
      explore example
      [[MultiSelectField.selectedExportValues]], [[SingleSelectField.optSelected]], [[OptionItem.exportValue]]

    • Returns whether the object is pending a lock or not.

      Returns boolean

      Part of the [[Lock]] API.

      const isPendingLock = baseObject.isPendingLock();

      Returns boolean

      Part of the [[Lock]] API.

      const lockPendingUnlock = baseObject.isPendingUnLock();

    • Returns whether the field is writable

      Returns boolean

      const firstNameClass = firstName.isWritable() ? 'active' : 'inactive';

    • Returns the Local Cache object for this Thread/Base Object.

      Returns LocalCache

    • Same as calling optLock().orElse(null)

      Returns Lock

    • Returns an array of all locked [[OptionItem]]s for this field. A locked [[OptionItem]] will show up on a form, but it won't be selectable.

      Returns EList<OptionItem>

      // see if any locked OptionItems are selected
      const selectedLocked = field.lockedOptions().filter(op => op.isSelected())
      explore example
      [[OptionItem.isSelected]]

    • The lookup function finds a single option in the list of options using the custom lookup properties of the option items. Custom lookup properties come in two varieties: unique and non-unique. Names beginning with an underbar (_) do not have to be unique. Names that do not begin with an underbar must be unique name/value pair for any one type of Relate element within a single organization. Thus, if the name begins with an underbar there could be more than one option that has the same name/value pair associated with it. In this case, the first matching option will be returned.

      Parameters

      • name: string
      • value: string

      Returns OptionItem

      // see whether the lowest or highest priority options were selected
      // assumes you already have the functions handleLowest, handleHighest, and handleOther
      const selExpVal = field.optSelected().map(op => op.exportValue());
      const low = field.lookup('_priorityLevel', 'lowest');
      const high = field.lookup('_priorityLevel', 'highest');
      low.isSelected() && handleLowest(low);
      high.isSelected() && handleHighest(high);
      !low.isSelected() && !high.isSelected() && handleOther(selExpval);
