html div往下移,HTML 层(DIV) 随鼠标事件移动?

div20*20||+rh;//右上角20*20的关闭区域

if(rh=20 && rw180 )document.title=rw+||可选||+rh;//绝对拖动条选择区域;

}

function dargit(o,e){

thiso = o;

canDrg = true;

if(!document.all){

lx = e.clientX; ly = e.clientY;

}else{

lx = event.x; ly = event.y;

}

if(document.all) thiso.setCapture();

st(o);//置前或置后

}

document.onmousemove = function(e){

if(!document.all){ x = e.clientX; y = e.clientY; }else{ x = event.x; y = event.y; }

if(canDrg){

//if(rh=20 && rw180 ){//如果要设定拖动区域可以作判断

var ofsx = x - lx;

thiso.style.left = parseInt(thiso.style.left) + ofsx;

lx = x;

var ofsy = y - ly;

thiso.style.top = parseInt(thiso.style.top) + ofsy;

ly = y;

//}else{canDrg=false;}

}

}

document.οnmοuseup=function(){

canDrg=false;//拖拽变量设为false

if(document.all && thiso != null){

//ie下，将清捕获;

thiso.releaseCapture();

thiso = null;

}

}

function set(obj){

obj=obj.parentNode.parentNode;

if(obj.getAttribute(rel));

//obj.style.zIndex=1;

}

function st(o){

var p = o.parentNode;

if(p.lastChild != o){

p.appendChild(o);

}

if(rh=20 && rw=180){

canDrg=false;

window.status=rw+|+rh;

if(p.firstChild == o) return;

p.insertBefore(o, p.firstChild);

}
