anchors retorna uma lista de todas as âncoras no documento.

Sintaxe

nodeList = document.anchors;

Exemplo

if ( document.anchors.length >= 5 ) {
  dump("dump found too many anchors");
  window.location = "http://www.google.com";
}

O c├│digo a seguir ├ę um exemplo que popula automaticamente um ├şndice de conte├║do com cada ├óncora encontrada na p├ígina:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>Test</title>
<script>
function init() {
  var toc = document.getElementById("toc");
  var i, li, newAnchor;
  for (i = 0; i < document.anchors.length; i++) {
    li = document.createElement("li");
    newAnchor = document.createElement('a');
    newAnchor.href = "#" + document.anchors[i].name;
    newAnchor.innerHTML = document.anchors[i].text;
    li.appendChild(newAnchor);
    toc.appendChild(li);
  }
}
</script>

</head>
<body onload="init()">

<h1>Title</h1>
<h2><a name="contents">Contents</a></h2>
<ul id="toc"></ul>

<h2><a name="plants">Plants</a></h2>
<ol>
    <li>Apples</li>
    <li>Oranges</li>
    <li>Pears</li>
</ol>

<h2><a name="veggies">Veggies</a></h2>
<ol>
    <li>Carrots</li>
    <li>Celery</li>
    <li>Beats</li>
</ol>

</body>

Notas

Por motivos de compatibilidade, o conjunto de ├óncoras retornadas por anchors cont├ęm apenas as ├óncoras criadas com o atributo name, n├úo incluindo as ├óncoras criadas com o atributo id.
