HTMLAnchorElement.relList - Web APIs 编辑

The HTMLAnchorElement.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 <a> element and the current document.

The property itself is read-only, meaning you can't substitute the DOMTokenList with another one, but its contents can still be changed.

Syntax

var relstr = anchorElt.relList;

Example

var anchors = document.getElementsByTagName("a");
var length = anchors.length;
for (var i = 0; i < length; i++) {
  var list = anchors[i].relList;
  var listLength = list.length;
  console.log("New anchor node found with", listLength, "link types in relList.");
  for (var j = 0; j < listLength; j++) {
    console.log(list[j]);
  }
}
