document.getElementsByName返回的是个数组

记住这个返回的是个数组document.getElementsByName. 取radio的值就这样取 l=document.getElementsByName("sitesearch");                 for(i=0;i<l.length;i++)                  {                      if(l[i].checked)                      {                                 ...........................                      }                                                                                  }
