HTMLLinkElement.relList - Web APIs 编辑

The HTMLLinkElement.relList read-only property reflects the rel attribute. It is a live DOMTokenList containing the set of link types indicating the relationship between the resource represented by the <link> element and the current document.

The property itself is read-only, meaning you can substitute the DOMTokenList by another one, but the content of the returned list can be changed.

Syntax

var relstr = linkElt.relList;

Example

var links = document.getElementsByTagName("link");
var length = links.length;
for (var i = 0; i < length; i++) {
  var list = links[i].relList;
  var listLength = list.length;
  console.log("New link found.");
  for (var j = 0; j < listLength; j++) {
    console.log(list[j]);
  }
}
