更改单选按钮名称javascript在IE中不工作

Question

我在jsp页面中有几个单选按钮。一旦页面加载后，我运行一个JavaScript方法，寻找某些单选按钮并更改它的名称，使它们像收音机组一样工作。

我这样做是因为单选按钮位于jsf表格内，编码时我无法访问name属性，我希望所有单选按钮都像收音机组一样工作。

不管怎样，脚本运行没有问题，单选按钮的名称已正确更改。

虽然这在FF 3（像收音机组那样工作）中工作，但它在IE 6或IE7中不起作用，虽然它们具有相同的“名称”属性。有谁知道我该如何解决这个问题？

function setRadioGroup (nombreRadio){ 
    var listaRadios = document.getElementsByTagName('input'); 
    var tam = listaRadios.length; 
    for (i = 0; i < tam; i++){ 
     if (listaRadios[i].type == 'radio' && listaRadios[i].title == 'Seleccionar'){ 
     listaRadios[i].name = nombreRadio; 
     } 
    } 
} 

编辑：添加网页的代码输出：

Answer 1

我终于得到了答案！

解决方案来自blog，但经过一些修改（博客，和其他许多人一样，解决了创建新元素的问题，而不是修改存在的问题）。

问题是Internet Explorer在运行时不允许修改某些属性。其中之一是属性名称。由于它不能被修改，行为不是你所期待的。解决方案是创建一个新元素，删除旧元素并将其替换为新元素。

这里的解决方案（与Firefox 3和IE 7的工作）：

<script> 
function setRadioGroup (name){ 
    var listaRadios = document.getElementsByTagName('input'); 
    var tam = listaRadios.length; 
    for (i = 0; i < tam; i++){ 
    cur = listaRadios[i]; 
    if (cur.type == 'radio'){ 
     try { 
     // if not IE, raise an error and go to catch.    
      element = document.createElement('<input onclick="alert(this.name + this.value);" type="radio" name="' + name + '" value="' + cur.value + '">'); 
      parentNode = cur.parentNode; 
      parentNode.insertBefore(element, cur); 
      parentNode.removeChild(cur); 
     } catch (err) { 
      cur.setAttribute('name', name); 
      cur.setAttribute('onclick', 'alert(this.name + this.value);'); 
     } 
    } 
    } 
} 
</script> 

<html> 
    <head> 
    <title>My Page</title> 
    </head> 
    <body onload="setRadioGroup('test')"> 
    <form name="myform" action="http://www.mydomain.com/myformhandler.cgi" method="POST"> 
     <div align="center"><br> 
     <input type="radio" value="Milk"> Milk<br> 
     <input type="radio" value="Butter" > Butter<br> 
     <input type="radio" value="Cheese"> Cheese 
     <hr> 
     <input type="radio" value="Water"> Water<br> 
     <input type="radio" value="Beer"> Beer<br> 
     <input type="radio" value="Wine" > Wine<br> 
     </div> 
    </form> 
    </body> 
</html>
