var _rect = document.all.ipt1.getBoundingClientRect();
alert("top:" + _rect.top + ",left:" + _rect.left + ",right:" + _rect.right+",bottom:" + _rect.bottom);

将下更代码改一下就可以了，它是设置控件值的！
function MM_findObj(n, d) { //v4.01
var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
if(!x && d.getElementById) x=d.getElementById(n); return x;
}
function MM_changeProp(objName,x,theProp,theValue) { //v6.0
var obj = MM_findObj(objName);
if (obj && (theProp.indexOf("style.")==-1 || obj.style)){
if (theValue == true || theValue == false)
eval("obj."+theProp+"="+theValue);
else eval("obj."+theProp+"='"+theValue+"'");
}
}
function MM_findObj(n, d) { //v4.01
var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
if(!x && d.getElementById) x=d.getElementById(n); return x;
}
function MM_changeProp(objName,x,theProp,theValue) { //v6.0
var obj = MM_findObj(objName);
if (obj && (theProp.indexOf("style.")==-1 || obj.style)){
if (theValue == true || theValue == false)
eval("obj."+theProp+"="+theValue);
else eval("obj."+theProp+"='"+theValue+"'");
}
}
