解决方案 »

  1.   

    var userid = seleObj.children[0].innerText; //不兼容FF, 改成
    var isie=document.all?true:false;
    var userid = (isie) ? seleObj.children[0].innerText : seleObj.children[0].innerText;.textContent;
      

  2.   

    var isie=document.all?true:false;
    var userid = (isie) ? seleObj.children[0].innerText : seleObj.children[0].textContent;
      

  3.   

    还是不行呀，报seleObj.children is undefined
    [Break on this error] var userid = seleObj.children[0].textContent
      

  4.   

    试下这个
    var userid = seleObj.childNodes[0].innerHTML;
