javascript怎么判断窗口宽度

javascript怎么判断ie窗口的宽度
如判断屏幕宽度：screen.width

[hbhbhbhbhb1021]

document.body.offsetWidth

[szsoho]

好像不行啊

[jiangtao088]

document.body.offsetTop
document.body.offsetWidth
要是不行那怪事还出了

[szsoho]

var width = screen.width;
if (isNS4) {
var divleft = document["divleft"];
if (width >= 1024) {
divleft.top = top.pageYOffset;
divleft.display = "";
divleft.visibility = "visible";
moveleftEdge();
}
我想把判断屏幕大小改成窗口大小，这样改了没有反应

[mingxuan3000]

var width = ...;
alert(width)
if (isNS4) {
alert("1111")
var divleft = document["divleft"];
if (width >= 1024) {
alert("222")
divleft.top = top.pageYOffset;
divleft.display = "";
divleft.visibility = "visible";
moveleftEdge();
}
alert("333")
