  1.   

      document.getElementById("table1").firstChild.removeChild(document.getElementById("table1").firstChild.childNodes[1]);
      

  2.   

    兄弟，注意结贴。
    还有，这种方法在火狐下提示错误！！
    firstChild方法有异同
      

  3.   


      var xx=document.getElementById("table1").firstChild.childNodes[1];
      xx.parentNode.removeChild(xx);
      

  4.   

    请问我直接 document.getElementById("table1").removeChild(document.getElementById("table1").firstChild.childNodes[1]);这么写为什么不对那
      

  5.   

    要删除的节点不是前面的那个节点的子节点，
    a.removeChild(b);//一般情况下其中b要为a的直接子节点
