这是一个,自由移动的图片的代码:
<script>
//让指定的对象在窗口内移动
//obj 要移动的对象
//act 动作 start:移动 stop:停止
function move(obj, act)

this.h = obj.clientHeight;
this.xx = 0;
this.yy = 0;
this.timer1 = null;
}
function movechip(hy_movebar)
{
eval("chip=" + hy_movebar);
//chip = hy_movebar;
pageX = window.document.body.scrollLeft;
pageW = window.document.body.offsetWidth - 8;
pageY = window.document.body.scrollTop;
pageH = window.document.body.offsetHeight;
chip.xx = chip.xx + chip.vx;

}

}
if(chip.xx >= pageX+pageW-chip.w) {

}
