document.getElementById('id').style.width=value
document.getElementById('id').style.height=value
document.getElementById('id').style.top=value
document.getElementById('id').style.left=value
获取:
value=document.getElementById('id').offsetLeft
value=document.getElementById('id').offsetTop
value=document.getElementById('id').offsetWidth
value=document.getElementById('id').offsetHeight
