我要从一个text表单i中取得value；然后再判断一个radio的value；然后再在另一个表单的value显示i+"A"或"B"!
请直接给出代码！！快呀！大哥！
var str1
str1=i.value
if(radio.checked=true){
text2.value=str1 & "A"
}else{
text2.value=str1 & "B"
}
不知是不是这个意思

是判断radio的value么？
<SCRIPT LANGUAGE="JavaScript">
<!--
function clk()
{
if( form1.r1.value != 0 )
form1.t1.value = form1.i.value + "A"
else
form1.t1.value = form1.i.value + "B"
}
//-->
</SCRIPT>
<form name=form1>
<br><input name=i>i
<br><input type=radio name=r1 value=1 onClick="clk()">r1
<br><input name=t1>
</form>
<html>
<head>
<script>
function add()
{
var a=document.getElementsByName("rr")
var str=""
for(i=0;i<a.length;i++)
{
if(a[i].checked){str=a[i].value}
}
f1.t2.value=f1.t1.value+str
}
</script>
</head>
<body>
<form name="f1" method="POST" action="">
<p>
<input type="text" name="t1" size="20"><input type="radio" value="A" checked name="rr">A<input type="radio" name="rr" value="B">B</p>
<p><input type="text" name="t2" size="20"></p>
<p><input type="button" value="按钮" name="B1" onclick="add()"></p>
</form>
</body>
</html>
参见如下程序：
_______________________________________________________________
<script>
function doit(){
bbvalue=document.aa.source1.value;
if(document.aa.source2[0].checked)
bbvalue+=document.aa.source2[0].value;
else
bbvalue+=document.aa.source2[1].value;
document.bb.showit.value=bbvalue;
return false;
}
</script>
<form name=aa onclick="return doit()">
<input type=text name=source1>
<input type=radio value=radio1 name=source2>
<input type=radio value=rado2 name=source2>
<input type=submit value=ok>
</form>
<form name=bb>
<textarea name=showit></textarea>
</form>
