怎么按顺序取一组文本框的值？急啊，大家帮帮忙
打个比方一组input框
<input type= "text " name= "a1 " id= "b1 ">
<input type= "text " name= "a2 id= "b2>
<input type= "text " name= "a3 id= "b3>
<input type= "text " name= "a4 id= "b4>
怎么按顺序取得这组input框的值，然后组成个集合，还有判定这组框中有没有空值。。
这里的name何id是动态生成的，不知道这组input框的数量，关键是如何按顺序取得这组框的值？
------解决方案--------------------
var textCollection = new Array();
var inputs = document.getElementsByTagName( "input ");
for(var i=0;i <inputs.length;i++)
{
if((s=inputs[i]).type== "text ")
{
if(v=s.value.replace(/(^\s+)|(\s+$)/g, " ").length> 0)
textCollection.push(s.value);
else
alert(s.id + ": 为空 ");
}
}
alert(textCollection);
------解决方案--------------------
看看行不，俺先去吃饭了，哈
