你如何用另一个 ddl 填充一个 ddl 并与 Internet Explorer 兼容，同时仍然能够横穿选项数组来设置选定的选项？

function func_copy_all()
{

  var ln_start_location = ((Number(document.getElementById('page_index').value) - 1) * Number(document.getElementById('page_size').value)) +1;
  for(i = ln_start_location; i < (ln_total_rows + 1); i++){
    //load the current city ddl with options
    var lo_city = document.getElementById('city_'+i);
    var lo_temp_city = document.getElementById('temp_city_selection');
         /*For IE*/
         var node = document.getElementById('city_cell_' + i);
         var lo_cell = document.createElement("TD");
         var lo_textNode = document.createTextNode(lo_temp_city);
         lo_cell.appendChild(lo_textNode);
         node.appendChild(lo_cell);

    //Believe innterHTML inside a div might be a problem for IE
    //lo_city.innerHTML = lo_temp_city.innerHTML;  

    //option value that needes to be selected
    var ls_selected_city = document.getElementById('city2_'+i).value;
    //Get the length of the ddl
    var optCount = lo_temp_city.options.length;
    //Traverse the array to get the index and set it to the city to selected
    for(var ln_j = 0; ln_j < optCount; ln_j++){
      if(lo_temp_city.options[ln_j].value == ls_selected_city){
      //set selected and break
      lo_city.options[ln_j].selected = "true";
      //break
      ln_j = optCount + 1;
      }
    }
  }
}

如果我使用innerHTML，我可以让它在firefox上正常工作，但不能在IE上工作？如果我避免使用 innerHTML，我有一个文本节点，我无法遍历该节点来设置所选值。

}

这适用于 Firefox 和 IE8。
