1.用dom结构
兼容netscape
<body>
<input id="qx" type="button" value="全选" name="Button1">
<script language="JavaScript">
function selClick(e)
{
var e = (e)?e:window.event;
var src = (e.target)?e.target:e.srcElement;
src.value = (src.value=="改变")?"全选":"改变";
}
document.getElementById('qx').onclick = selClick;
</script>
</body>
2.直接传入元素对象
<body>
<script language="JavaScript">
function selClick(o)
{
o.value = (o.value=="改变")?"全选":"改变";
}
</script>
<input type="button" value="全选" onclick="selClick(this)" name="Button1">
</body>

是不是这个？
document.forms[0].Button1.value = "全";
document.forms[0].Button1.value = "全";
