Disable All Links with JavaScript

window.onload= function(){
        DisableEnableLinks(true)
}

function DisableEnableLinks(xHow){
  objLinks = document.links;
  for(i=0;i<objLinks.length;i++){
    objLinks[i].disabled = xHow;
    //link with onclick
    if(objLinks[i].onclick && xHow){ 
        objLinks[i].onclick = new Function("return false;" + objLinks[i].onclick.toString().getFuncBody());
    }
    //link without onclick
    else if(xHow){ 
      objLinks[i].onclick = function(){return false;}
    }
    //remove return false with link without onclick
    else if(!xHow && objLinks[i].onclick.toString().indexOf("function(){return false;}") != -1){           
      objLinks[i].onclick = null;
    }
    //remove return false link with onclick
    else if(!xHow && objLinks[i].onclick.toString().indexOf("return false;") != -1){ 
      strClick = objLinks[i].onclick.toString().getFuncBody().replace("return false;","")
      objLinks[i].onclick = new Function(strClick);
    }
  }
}

String.prototype.getFuncBody = function(){
  var str=this.toString();
  str=str.replace(/[^{]+{/,"");
  str=str.substring(0,str.length-1);  
  str = str.replace(/\n/gi,"");
  if(!str.match(/\(.*\)/gi))str += ")";
  return str;
}


how can I disable only the links in a certain div?
objLinks = document.getElementById("divID").getElementsByTagName("a");
