    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]]

    • 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

      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<I> }

      // 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<I>

      // 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 an edit URL for this object, else a blank string.

      Returns string

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

    • 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;

    • The [[Id]] of this object bounded to T.

      Returns Id<I>


      const displayDiv = `<div class="object-card" id="${baseObject.id()}">
        <div class="title">${baseObject}</div>
        <div class="body">Hello World!</div>
      </div>;

      Returns boolean

      Part of the [[Lock]] API.

      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 whether the object is pending an unlock or not.

      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);
      explore example
      [[Java.Optional.map]], [[SingleSelectField.optSelected]], [[OptionItem.isSelected]]

    • Parameters

      • Optionaloptions: string

      Returns string

    • Returns the [[FieldMetaData]] object that this describes this field.

      Returns FieldMetaData<T>

      const firstNameClass = firstName.metaData().styleClass();
      explore example
      [[FieldMetaData.styleClass]]

    • The modified date of this object.

      Returns Instant

      const isModified = baseObject.modified();

    • The [[User]] that last modified this object.

      Returns User

      const modifierName = baseObject.modifier().fullName();

    • Returns an array of all obsolete [[OptionItem]]s for this field. [[OptionItem]]s are marked obsolete if they are never going to be used again, but still need to exist for legacy data. Will not show up on a form.

      Returns EList<OptionItem>

      // get the groups containing each of the obsolete OptionItems
      const obsoleteGroups = field.obsoleteOptions().map(op => [op, op.groups()])
      explore example
      [[OptionItem.groups]]

    • Optional value for this field. Same as [[valOpt]]. Try to use this as often as you can over val(); Null-pointer exceptions can be a pain, and this will provide a measure of safety. Try to reserve val() for situations where a field is required and you know that the value cannot be null.

      Returns Optional<T>

      const middleName = middleName.opt().orElse('No Middle Name Set!');
      // or, similarly 
      const middleName = middleName.val() || 'No Middle Name Set!'
      explore example

      Parameters

      • classType: string | number

      Returns Optional<BaseObject<any>>

      const ancestors = obj.optAncestor(1000001).ifPresent(a => console.log('${a} exists'));
      explore example
      [[Java.Optional.ifPresent]]

    • Returns an object where the members are the export value and the values are [[OptionItem]].

      Returns { [exportValue: string]: OptionItem }

      // get an alphabetized list of the export values
      const orderedExportVals = Object.keys(field.optionsByExport()).sort();

    • Returns an object where the members are the name and the values are [[OptionItem]].

      Returns { [name: string]: OptionItem }

      // only get the options shorter than 20 characters
      const onlyShortOps = Object.keys(field.optionsByName()).filter(key => key.length < 20)

    • Returns the [[Lock]]

      Returns Optional<Lock>

      Part of the [[Lock]] API.

      const lockExpire = baseObject.optLock();

    • A [[Java.Optional]] of the current object's parent object.

      Parameters

      • OptionalclassType: string | number

      Returns Optional<BaseObject<any>>

      const ancestors = obj.optAncestor(1000001).ifPresent(a => console.log('${a} found'));

      Type Parameters

      Parameters

    • Reset the current object so that it is cleared from the cache and looked up from the database.

      Returns void

    • Returns a list of selected [[OptionItem]]s.

      // get the stati of the selected OptionItems
      const selStatus = field.selectedOptions().map(op => [op, op.status()]);

    • Sets or clears the OptionItem with the given ID. Returns true if successful.

      Parameters

      • id: string | Id<OptionItem>

        The ID of the OptionItem to set

      • Optionalchecked: boolean

        Defaults to true

      Returns boolean

    • Sets or clears the OptionItem with the given export value. Returns true if successful.

      Parameters

      • id: string

        The export value of the OptionItem to set

      • Optionalchecked: boolean

        Defaults to true

      Returns boolean

    • Sets or clears the OptionItem with the given name. Returns true if successful.

      Parameters

      • name: string

        The name of the OptionItem to set

      • Optionalchecked: boolean

    • The [[Id]] or [[AltId]] that the system deems most relevant.

      Returns AltId<I> | Id<I>


      const displayDiv = `<div class="object-card" id="${baseObject.topId()}">
        <div class="title">${baseObject}</div>
        <div class="body">Hello World!</div>
      </div>;

    • Returns the bluestep.js classpath for the current object.

      Returns string

      const isBool = testForm.fields.mysteryField.typeName().toLowerCase().includes('boolean')

    • Makes changes to the database for this object

      Returns void

    • Gets the field's value if there is one, and will otherwise return null. Some overrides of this method have default return-values for convenience but, that would not make sense for this: the general-use case. In situations where the value might be null (e.g. non required field), consider using optional chaining: field.val()?.toString(). The preferred method to handle nulls in bs.js is simply [[opt]]/[[valOpt]]; as the methods available off of that can handle virtually any situation.

      This is identical to calling field.opt().orElse(null).

      Returns T

      // it is important to notice that, due to how JavaScript works, doubleVal will evaluate to 0 if numberField.val() is null.
      const doubleVal = numberField.val() * 2;

    • Set the field's value.

      Parameters

      • newValue: T

        The value to be put into the field.

      Returns void

      // make the field say `hello`
      field.val('hello');

    • Optional value for this field. Alias for [[opt]].

      Returns Optional<T>

      date.valOpt().map(val => `Report Date: ${val}`).orElse('No Date');
      explore example
      [[Java.Optional.map]], [[Java.Optional.orElse]]

    • Returns string

    • The version of this object or empty string if it doesn't exist.

      Returns string

      const version = baseObject.version();

    • The versions of this object.

      Returns EList<BaseObject<I>>

      const versions = baseObject.versions();

    • Returns a view URL for this object, if it has one. This value is always a relative URL, meaning it does not contain the protocol prefix or domain name such as http://xyz.bluestep.net.

      Returns string

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