lt( )

Refines a query or filter to match items whose specified property value is less than the specified value.

Description

The lt() function refines a WixDataQuery or WixDataFilter to only match items where the value of the specified property is less than the specified value.

It only matches values of the same type. For example, a number value stored as a String type does not match the same number stored as a Number type.

If a property contains a number as a String, that value will be compared alphabetically and not numerically. Items that do not have a value for the specified property are ranked lowest.

The following types of properties can be compared:

Number: Compares numerically.
Date: Compares JavaScript Date objects.
String: Compares lexicographically, so "Text" is less than "text".
Reference: Compares by the ID of the referenced item as a String.

Syntax

function lt(propertyName: string, value: string | number | Date): WixDataQuery
