只有firefor下可以显示进度条。。。IE，Google Chrome下都是不行的，只有整个for跑完才能显示出来...

<div class="adminMainTitle">
    <div class="adminSidebarTitleInternal">
        正在导入，请稍后....</div>
</div>
<div class="adminMainPanel">
    <textarea id="iting" cols="200" rows="20"></textarea>
</div>
<script>
    var hisIds = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15];
    $(document).ready(function () {
        if(hisIds.length==0){
            $("#iting").val("已导入");
            return;
        }
        setTimeout("go()",1000);
    });
    function go()
    {
        //导入
        for (var i = 0; i < hisIds.length; i++) {
           var id = hisIds[i];
           $.ajax({
              type: "POST",
              url: "Importting.aspx?ajax=true",
              data: "id="+id,
              async: false,
              success: function(msg){
                 
                $("#iting").val($("#iting").val() + "\r\n" + msg);
                document.getElementById("iting").scrollTop=document.getElementById("iting").scrollHeight;
              },
              error:function(msg)
