默认为打开的js，如何修改默认关闭。

var status = 1;
var Menus = new DvMenuCls;

document.onclick=Menus.Clear;
function switchSysBar(){
var switchPoint=document.getElementById("switchPoint");
var frmTitle=document.getElementById("frmTitle");
     if (1 == window.status){
  window.status = 0;
  //alert(switchPoint);

          switchPoint.style.backgroundImage = 'url(images/left.gif)';
          frmTitle.style.display="none"
     }
     else{
  window.status = 1;
          switchPoint.style.backgroundImage = 'url(images/right.gif)'; 
          frmTitle.style.display=""
     }
}

function DvMenuCls(){
var MenuHides = new Array();
this.Show = function(obj,depth){
var childNode = this.GetChildNode(obj);
if (!childNode){return ;}
if (typeof(MenuHides[depth])=="object"){
this.closediv(MenuHides[depth]);
MenuHides[depth] = '';
};
if (depth>0){
if (childNode.parentNode.offsetWidth>0){
childNode.style.left= childNode.parentNode.offsetWidth+'px';

}else{
childNode.style.left='100px';
};

childNode.style.top = '-2px';
};

childNode.style.display ='none';
MenuHides[depth]=childNode;

};
this.closediv = function(obj){
if (typeof(obj)=="object"){
if (obj.style.display!='none'){
obj.style.display='none';
}
}
}
this.Hide = function(depth){
var i=0;
if (depth>0){
i = depth
};
while(MenuHides[i]!=null && MenuHides[i]!=''){
this.closediv(MenuHides[i]);
MenuHides[i]='';
i++;
};

};
this.Clear = function(){
for(var i=0;i<MenuHides.length;i++){
if (MenuHides[i]!=null && MenuHides[i]!=''){
MenuHides[i].style.display='none';
MenuHides[i]='';
}
}
}
this.GetChildNode = function(submenu){
for(var i=0;i<submenu.childNodes.length;i++)
{
if(submenu.childNodes[i].nodeName.toLowerCase()=="div")
{
var obj=submenu.childNodes[i];
break;
}
}
return obj;
}

}


function getleftbar(obj){
var leftobj;
var titleobj=obj.getElementsByTagName("a");
leftobj = document.all ? frames["frmleft"] : document.getElementById("frmleft").contentWindow;
if (!leftobj){return;}
var menubar = leftobj.document.getElementById("menubar")
if (menubar){
if (titleobj[0]){
document.getElementById("leftmenu_title").innerHTML = titleobj[0].innerHTML;
}
var a=obj.getElementsByTagName("ul");
for(var i=0;i<a.length;i++){
menubar.innerHTML = a[i].innerHTML;
//alert(a[i].innerHTML);
}
}
}

这段代码，默认是处于打开状态，我想他默认处于关闭状态，该如何修改？

试试

function switchSysBar(){
var switchPoint=document.getElementById("switchPoint");
var frmTitle=document.getElementById("frmTitle");


     if (  window.status!=1){
  
  //alert(switchPoint);
  window.status = 1;
          switchPoint.style.backgroundImage = 'url(images/right.gif)'; 
          frmTitle.style.display=""
     }
     else{
     window.status = 0;
          switchPoint.style.backgroundImage = 'url(images/left.gif)';
          frmTitle.style.display="none"
     }
}

}

switchSysBar();  // 马上执行，如出错放到 window.onload 里执行
