JSP 全选问题
做一个邮件系统的时候，我想实现当点击全选的时候，把所有选中的Email都显示在一个文本框中，Email地址是循环读取出来的，，但读取的时候，只读取到第一个Email地址..
哪位大虾帮帮忙......急！
JS页面代码
function SetChecked(boxname,phone){
f=document.form1;
for( i=0 ; i<f.elements.length ; i++){
if (f.elements[i].name==boxname) {
f.elements[i].checked=true;
for(j = 0; j<f.elements[i]..length;j++){
var send = document.getElementById("phone1").value;
document.getElementById("phone1").value = document.getElementById("phone1").value + phone + ";";
}
}
}
}
}

[解决办法]
设计思路有问题，不能在选中checkbox的时候就进行拼串，那要是先选中然后取消然，岂不是没有去掉；要是先选中再取消再选中，岂不是拼两次；应该是再最后提交的时候，进行拼串；其实根本用不着拼串，下个页面可以直接接收的，前台只需要判断最少选中一个进行发送就行
[解决办法]
用复选框的value
