HTMLAreaElement.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 <area> element and the current document.

The property itself is read-only, meaning you can't substitute the DOMTokenList by another one, but the content of the returned list can be changed.

句法

var relstr = areaElt.relList;

范例

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