打破Javascript中的嵌套循环的最佳方法是什么？

//Write the links to the page.
for (var x = 0; x < Args.length; x++)
{
   for (var Heading in Navigation.Headings)
   {
      for (var Item in Navigation.Headings[Heading])
      {
         if (Args[x] == Navigation.Headings[Heading][Item].Name)
         {
            document.write("<a href=\"" 
               + Navigation.Headings[Heading][Item].URL + "\">" 
               + Navigation.Headings[Heading][Item].Name + "</a> : ");
            break; // <---HERE, I need to break out of two loops.
         }
      }
   }
}
