SVGPointList: initialize() method
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.
The initialize()
method of the SVGPointList
interface clears the list then adds a single new SVGPoint
object to the list.
Syntax
js
initialize(obj)
Parameters
Return value
The added SVGPoint
object.
Exceptions
NoModificationAllowedError
DOMException
-
Thrown if the list is read-only.
Examples
The following example shows an SVG which contains a <polyline>
with five coordinate pairs. Returning SVGPointList.length
gives the value 5
. After calling initialize()
, returning SVGPointList.length
gives the value 1
.
html
<svg id="svg" viewBox="-10 -10 120 120" xmlns="http://www.w3.org/2000/svg">
<polyline
id="example"
stroke="black"
fill="none"
points="50,0 21,90 98,35 2,35 79,90" />
</svg>
js
let example = document.getElementById("example");
console.log(example.points.length); //5;
let svgPoint = document.getElementById("svg").createSVGPoint();
example.points.initialize(svgPoint);
console.log(example.points.length); //1
