我的表格单击某行实现颜色的改变，我已经实现。里面有个td项为radio,现在想把radio项隐藏，通过单击某行实现该行对应的radio项被选中，并通过一个button实现该行信息的显示，想问下如何实现？谢谢:)

HTML code


<style>
.hide{display:none;}
</style>

<script>
dodo.selected=null;
function dodo(tr){
    var rs=tr.getElementsByTagName("input");
    if(rs.length==0)return;
    rs[0].checked=true;
    rs[0].className='';
    if(rs[0]!=dodo.selected&&dodo.selected!=null)dodo.selected.className="hide";
    dodo.selected=rs[0];
}
function show(){
    var rows=document.getElementById("tab").rows;
    for(var i=0;i<rows.length;i++){
        var rs=rows[i].getElementsByTagName("input");
        if(rs.length==0)continue;
        if(rs[0].checked){
            alert(rows[i].innerHTML);//不知道你要显示这一行的什么信息
            break;
        }
    }
}
</script>

<table id="tab">
<tr onclick="dodo(this)"><td><input type=radio name=choose class="hide" ></td><td>1111</td><tr>
