SVGTextContentElement

Baseline Widely available *

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

* Some parts of this feature may have varying levels of support.

The SVGTextContentElement interface is implemented by elements that support rendering child text content. It is inherited by various text-related interfaces, such as SVGTextElement, SVGTSpanElement, and SVGTextPathElement.

Instance properties

This interface also inherits properties from its parent, SVGGraphicsElement.

SVGTextContentElement.textLength Read only: An SVGAnimatedLength reflecting the textLength attribute of the given element.
SVGTextContentElement.lengthAdjust Read only: An SVGAnimatedEnumeration reflecting the lengthAdjust attribute of the given element. The numeric type values represent one of the LENGTHADJUST_* constant values.

Instance methods

This interface also inherits methods from its parent, SVGGraphicsElement.

SVGTextContentElement.getNumberOfChars(): Returns a long representing the total number of addressable characters available for rendering within the current element, regardless of whether they will be rendered.
SVGTextContentElement.getComputedTextLength(): Returns a float representing the computed length for the text within the element.
SVGTextContentElement.getSubStringLength(): Returns a float representing the computed length of the formatted text advance distance for a substring of text within the element. Note that this method only accounts for the widths of the glyphs in the substring and any extra spacing inserted by the CSS 'letter-spacing' and 'word-spacing' properties. Visual spacing adjustments made by the 'x' attribute is ignored.
SVGTextContentElement.getStartPositionOfChar(): Returns a DOMPoint representing the position of a typographic character after text layout has been performed.

Note: In SVG 1.1 this method returned an SVGPoint.
SVGTextContentElement.getEndPositionOfChar(): Returns a DOMPoint representing the trailing position of a typographic character after text layout has been performed.

Note: In SVG 1.1 this method returned an SVGPoint.
SVGTextContentElement.getExtentOfChar(): Returns a DOMRect representing the computed tight bounding box of the glyph cell that corresponds to a given typographic character.
SVGTextContentElement.getRotationOfChar(): Returns a float representing the rotation of typographic character.
SVGTextContentElement.getCharNumAtPosition(): Returns a long representing the character which caused a text glyph to be rendered at a given position in the coordinate system. Because the relationship between characters and glyphs is not one-to-one, only the first character of the relevant typographic character is returned.
SVGTextContentElement.selectSubString() Deprecated: Selects text within the element.

Static properties

LENGTHADJUST_UNKNOWN (0): The type is not one of predefined types. It is invalid to attempt to define a new value of this type or to attempt to switch an existing value to this type.
LENGTHADJUST_SPACING (1): Corresponds to the value spacing.
LENGTHADJUST_SPACINGANDGLYPHS (2): Corresponds to the value spacingAndGlyphs.
