 DK_MOVE_total += DK_MOVE_amount;

}

var DK_MOVE_amount=0;
var DK_MOVE_total=0;
var DK_MOVE_handle ;
var DK_MOVE_winHeight, DK_MOVE_winWidth;

//启动滚动窗口
function DK_MOVE_START(){
 DK_MOVE_winHeight= document.body.offsetHeight + 30;
 DK_MOVE_winWidth = document.body.offsetWidth + 10 ;
 window.moveTo(window.screen.availWidth-DK_MOVE_winWidth, window.screen.availHeight);
 DK_MOVE_handle = setInterval("DK_MOVE_moveWindowUp()",70);
}

document.body.oncontextmenu = new Function("return false;");
document.body.onselectstart =  new Function("return false;");
document.body.onload =  new Function("return DK_MOVE_START();");

/*调用方法*/
请在需要自动上升的页面内加入以下代码：
