Word.Font class

Package:

word

Represents a font.

Extends

OfficeExtension.ClientObject

Remarks

[ API set: WordApi 1.1 ]

Examples

// Change the font color
// Run a batch operation against the Word object model.
await Word.run(async (context) => {

    // Create a range proxy object for the current selection.
    const selection = context.document.getSelection();

    // Queue a command to change the font color of the current selection.
    selection.font.color = 'blue';

    // Synchronize the document state by executing the queued commands,
    // and return a promise to indicate task completion.
    await context.sync();
    console.log('The font color of the selection has been changed.');
});

Properties

bold	Specifies a value that indicates whether the font is bold. True if the font is formatted as bold, otherwise, false.
color	Specifies the color for the specified font. You can provide the value in the '#RRGGBB' format or the color name.
context	The request context associated with the object. This connects the add-in's process to the Office host application's process.
doubleStrikeThrough	Specifies a value that indicates whether the font has a double strikethrough. True if the font is formatted as double strikethrough text, otherwise, false.
hidden	Specifies a value that indicates whether the font is tagged as hidden. True if the font is formatted as hidden text, otherwise, false.
highlightColor	Specifies the highlight color. To set it, use a value either in the '#RRGGBB' format or the color name. To remove highlight color, set it to null. The returned highlight color can be in the '#RRGGBB' format, an empty string for mixed highlight colors, or null for no highlight color. Note: Only the default highlight colors are available in Office for Windows Desktop. These are "Yellow", "Lime", "Turquoise", "Pink", "Blue", "Red", "DarkBlue", "Teal", "Green", "Purple", "DarkRed", "Olive", "Gray", "LightGray", and "Black". When the add-in runs in Office for Windows Desktop, any other color is converted to the closest color when applied to the font.
italic	Specifies a value that indicates whether the font is italicized. True if the font is italicized, otherwise, false.
name	Specifies a value that represents the name of the font.
size	Specifies a value that represents the font size in points.
strikeThrough	Specifies a value that indicates whether the font has a strikethrough. True if the font is formatted as strikethrough text, otherwise, false.
subscript	Specifies a value that indicates whether the font is a subscript. True if the font is formatted as subscript, otherwise, false.
superscript	Specifies a value that indicates whether the font is a superscript. True if the font is formatted as superscript, otherwise, false.
underline	Specifies a value that indicates the font's underline type. 'None' if the font isn't underlined.

Methods

load(options)	Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(propertyNames)	Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(propertyNamesAndPaths)	Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
set(properties, options)	Sets multiple properties of an object at the same time. You can pass either a plain object with the appropriate properties, or another API object of the same type.
set(properties)	Sets multiple properties on the object at the same time, based on an existing loaded object.
toJSON()	Overrides the JavaScript toJSON() method in order to provide more useful output when an API object is passed to JSON.stringify(). (JSON.stringify, in turn, calls the toJSON method of the object that's passed to it.) Whereas the original Word.Font object is an API object, the toJSON method returns a plain JavaScript object (typed as Word.Interfaces.FontData) that contains shallow copies of any loaded child properties from the original object.
track()	Track the object for automatic adjustment based on surrounding changes in the document. This call is a shorthand for context.trackedObjects.add(thisObject). If you're using this object across .sync calls and outside the sequential execution of a ".run" batch, and get an "InvalidObjectPath" error when setting a property or invoking a method on the object, you need to add the object to the tracked object collection when the object was first created. If this object is part of a collection, you should also track the parent collection.
untrack()	Release the memory associated with this object, if it has previously been tracked. This call is shorthand for context.trackedObjects.remove(thisObject). Having many tracked objects slows down the host application, so please remember to free any objects you add, once you're done using them. You'll need to call context.sync() before the memory release takes effect.

Returns

void

set(properties)

Sets multiple properties on the object at the same time, based on an existing loaded object.

set(properties: Word.Font): void;

Parameters

properties

Word.Font

Returns

void

toJSON()

Overrides the JavaScript toJSON() method in order to provide more useful output when an API object is passed to JSON.stringify(). (JSON.stringify, in turn, calls the toJSON method of the object that's passed to it.) Whereas the original Word.Font object is an API object, the toJSON method returns a plain JavaScript object (typed as Word.Interfaces.FontData) that contains shallow copies of any loaded child properties from the original object.

toJSON(): Word.Interfaces.FontData;

Returns

Word.Interfaces.FontData

track()

Track the object for automatic adjustment based on surrounding changes in the document. This call is a shorthand for context.trackedObjects.add(thisObject). If you're using this object across .sync calls and outside the sequential execution of a ".run" batch, and get an "InvalidObjectPath" error when setting a property or invoking a method on the object, you need to add the object to the tracked object collection when the object was first created. If this object is part of a collection, you should also track the parent collection.

track(): Word.Font;

Returns

Word.Font

untrack()

Release the memory associated with this object, if it has previously been tracked. This call is shorthand for context.trackedObjects.remove(thisObject). Having many tracked objects slows down the host application, so please remember to free any objects you add, once you're done using them. You'll need to call context.sync() before the memory release takes effect.

untrack(): Word.Font;

Returns

Word.Font
