bread_crumb.onload("innerHTMLに入れるID", "セパレータ", "〜/で表示されるファイル名");

例) 現在のページ http://www.hoge.com/page1/page2/index.html
// 出力
※sitemap.jsが別途必要
sitemap.js（サイトマップ）の記述方法
sitemap.js内の文字は現在のURLを小文字に変換するため
オブジェクト名も小文字で記述すること
例）/index.html
/page1/index.html
/page1/page2/index.html
// 1.フォルダー単位でオブジェクトを生成
var Root = new Object();
Root.page1 = new Object();
Root.page1.page2 = new Object();
// 2.ページ名を記述(index.htmlの場合はindexとする)
Root.index = "HOME";
Root.page1.index = "PAGE1";
Root.page1.page2.index = "PAGE2";
※フォルダー内にindex.htmlしか存在しない場合は以下の記述も許可
Root.page1.page2 = "PAGE2";
※その他
