利用JavaScriptDOM函数动态创建radiobuttons后在IE里无法做选择问题的解决

function createCxtjRadioButtons(data,cxtjId,cxtjTagId){
    var tagCxtj = document.getElementById(cxtjTagId);
    tagCxtj.removeChild(tagCxtj.childNodes[0]);
    for (var key in data) {
      var val = data[key];
      var input = document.createElement("input");
      input.setAttribute("name",cxtjId);
      input.setAttribute("type","radio");
      input.setAttribute("value",key);
      tagCxtj.appendChild(input);
      var label = document.createElement("label");
      label.setAttribute("for",input_id);
      label.appendChild(document.createTextNode(val));   
      tagCxtj.appendChild(label); 
    }    
}

function createCxtjRadioButtons(data,cxtjId,cxtjTagId){
    var tagCxtj = document.getElementById(cxtjTagId);
    tagCxtj.removeChild(tagCxtj.childNodes[0]);
    for (var key in data) {
      var val = data[key];
      var input = createElement("input", cxtjId); 
      input.setAttribute("type","radio");
      input.setAttribute("value",key);
      tagCxtj.appendChild(input);
      var label = document.createElement("label");
      label.setAttribute("for",input_id);
      label.appendChild(document.createTextNode(val));   
      tagCxtj.appendChild(label); 
    }    
}

function createElement(type, name) {
   var element = null;

   try {
      // First try the IE way; if this fails then use the standard way
      element = document.createElement('<'+type+' name="'+name+'">');
   } catch (e) {
      // Probably failed because we’re not running on IE
   }
   if (!element) {
      element = document.createElement(type);
      element.name = name;
   }
   return element;
}
