CSSUnparsedValue - Web APIs 编辑

Experimental

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The CSSUnparsedValue interface of the CSS Typed Object Model API represents property values that reference custom properties. It consists of a list of string fragments and variable references.

Custom properties are represented by CSSUnparsedValue and var() references are represented using CSSVariableReferenceValue.

Constructor

CSSUnparsedValue.CSSUnparsedValue()

Creates a new CSSUnparsedValue object.

Properties

CSSUnparsedValue.length

Returns the number of items in the CSSUnparsedValue object.

Methods

CSSUnparsedValue.entries()

Returns an array of a given object's own enumerable property [key, value] pairs in the same order as that provided by a for...in loop (the difference being that a for-in loop enumerates properties in the prototype chain as well).

CSSUnparsedValue.forEach()

Executes a provided function once for each element of the CSSUnparsedValue object.

CSSUnparsedValue.keys()

Returns a new Array Iterator object that contains the keys for each index in the CSSUnparsedValue object.

CSSUnparsedValue.values()
