Specific Methods

There are no specific methods for this object.

Inherited Methods

The following methods are common to all Item objects: Ⓓ Ⓞ

🅼 addClasses(classes) itemapItem

Description: This method adds one or more custom CSS class names to an item, allowing for dynamic styling. You can pass a single class name, multiple class names separated by spaces, or an array of class names. If any class names are invalid, the method returns false and no classes are added.

Example:

item.addClasses("emphasized error");

In this example, the item will have the CSS classes emphasized and error added to it for styling purposes.

🅼 clearRequiredMessage() itemapItem

Description: Validates the item data but prevents any required field error messages from being displayed. This is useful in scenarios where you want to perform validation without user feedback.

Example:

item.clearRequiredMessage();

Use this method when you need to validate the item but do not wish to show error messages to the user.

🅼 connectEvent(eventName, callbackFunction) itemapItem

Description: Connects a method to an item event, allowing for dynamic behavior based on user actions or item changes. It returns a handle object that represents the connection, which can be used to disconnect the event later.

Example:

var hndl = item.connectEvent('onItemChange', function ()
{
    if (item.getBOAttr().getValue() === 'Yes') {
        form.getBO().F_SectionA.setVisible(true);
    }
}
)
;

Here, we connect a method to the onItemChange event that makes a section visible if the item's value is 'Yes'.

🅼 disconnectEvent(eventHandle) itemapItem

Description: Disconnects a previously connected event handler using the handle object returned by item.connectEvent. This is essential to prevent multiple instances of the event handler from being attached.

WARNING

If you connect an item event, you must also disconnect it in the same event. Otherwise, multiple versions of the connected code are attached every time the event is triggered.

Example:

var hndl = item.connectEvent('onItemChange', function()
{
    if (item.getBOAttr().getValue() === 'Yes')
        form.getBO().F_SectionA.setVisible(true);
}
)
;
item.disconnectEvent(hndl);

This example demonstrates connecting to an event and then immediately disconnecting it to ensure the event handler does not persist unnecessarily.

🅼 getActive() itemapItem

Description: Returns true if the item is active and false if it has been made read-only by a rule, stage, or custom JavaScript.

Example:

var isActive = item.getActive();

Use this method to check whether an item is active or read-only in your application logic.

🅼 getChildren() item

• Description: If an item contains children (e.g., a Section or Tab Folder), it returns a list object providing access to all direct children items. This list has getLength() and get(index) methods.
• Example: Rest all numbers inside a section to 0:

  var list = item.getChildren();
  for(var i = 0; i < list.getLength(); i++) {

If the user is not editing, then it will be the same as setValue(). This method works on direct input items such as single line, multi line, number, currency, email and website.

  // Sets the title of an item to "Email Address".

🅼 setValid(valid, msg) apItem

• Description: Overrides the current validity state of data in an item. Setting valid to false marks the data as invalid and can prevent form submission, with an optional custom error message.

• Example:

  item.setVisible(true); // Makes the item visible
  item.setVisible(false); // Hides the item

🅼 validate() apItem

• Description: Triggers the validation process for a data item. Use this method to manually initiate the validation rules applied to the item, ensuring the data entered by the user meets the required criteria before proceeding. validate() takes no parameters.

🅼 getColumnHeaders() item

• Description: Retrieves the current configuration of column headers for a table, including each column's ID, title, and width.

  var headers = item.getColumnHeaders();
  for(var h in headers) {
    console.log("ID=" + headers[h].id + ", Title=" + headers[h].title + ", Width=" + headers[h].width);
  }

• Description: Allows you to dynamically set or update the column headers of a table.

  var headers = [
    {id: "F_Currency1", title: "Currency", width: 20},
