This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The Selection.addRange() method adds a Range to a Selection.
addRange(range)
None (undefined).
Note: Currently only Firefox supports multiple selection ranges, other browsers will not add new ranges to the selection if it already contains one.
<p> I <strong>insist</strong> that you <strong>try</strong> selecting the <strong>strong words</strong>. </p> <button>Select strong words</button>
let button = document.querySelector("button");
button.addEventListener("click", () => {
const selection = window.getSelection();
const strongElems = document.getElementsByTagName("strong");
if (selection.rangeCount > 0) {
selection.removeAllRanges();
}
for (const node of strongElems) {
const range = document.createRange();
range.selectNode(node);
selection.addRange(range);
}
});
