SVGSVGElement: getElementById() method

The getElementById() method of the SVGSVGElement interface searches the SVG document fragment (i.e., the search is restricted to a subset of the document tree) for an Element whose id property matches the specified string.

Syntax

getElementById(id)

Parameters

• id
  • : The ID of the element to locate. The ID is a case-sensitive string which is unique within the SVG document fragment; only one element should have any given ID.

Return value

An Element object describing the DOM element object matching the specified ID, or null if no matching element was found in the SVG document fragment.

Examples

</svg>
<button id="getElementButton">Get Element</button>
<p id="elementDisplay"></p>

const svgElement = document.getElementById("exampleSVG");
const getElementButton = document.getElementById("getElementButton");
const elementDisplay = document.getElementById("elementDisplay");

getElementButton.addEventListener("click", () => {
  const circleElement = svgElement.getElementById("circle1");
  if (circleElement) {
    elementDisplay.textContent = `Element found: ${circleElement.tagName}`;
  } else {
    elementDisplay.textContent = "Element not found.";
  }
});
