Answer 1

我做了一个DIV，显示文件正在上传中:function Click()
{
CreateWaitDiv();
                try
                {
                    __doPostBack('<%=btnUpload.ClientID%>'.replace(/\_/g, '$'), '');
                }
                catch(e)
                {
                    document.body.removeChild($('___showConfirmDialog'));
                    document.body.removeChild($('___showConfirmDialogContainer'));
                    alert('文件不存在')
                }
                break;
}function CreateWaitDiv()
    {
         var tempTop = document.body.scrollTop;
        var bodyHeight = document.body.clientHeight;
        var bodyWidth  = document.body.clientWidth;
        var bodyScrollHeight = document.body.scrollHeight;
        var obj = document.createElement("div");
        var obj2 = document.createElement("div");
    
        obj.id="___showConfirmDialog";
        obj2.id="___showConfirmDialogContainer"
        obj.style.position = "absolute";
        obj2.style.position = "absolute";
        obj.style.backgroundColor="#000000";
        obj2.style.backgroundColor = "#ffffff";
        obj.style.filter = "alpha(opacity=50)";
        obj.style.opacity=0.5;
        obj2.className = "div_b2 Div";
        
        obj.style.height = bodyHeight+bodyScrollHeight;
        obj2.style.height = 100 + "px";
        obj.style.width = bodyWidth
        obj2.style.width = 300 + "px";
        obj.style.left = 0;
        obj2.style.left = (parseInt(bodyWidth) - 300)/2;
        obj.style.top = tempTop-bodyScrollHeight;
        obj2.style.top = parseInt(tempTop) + (parseInt(bodyHeight) - 100)/2;
        tempinnerHtml = "<BR><BR><table class='table_layout_w100'><tr><td class='td_middle td_center'>上传中...</td></tr></table>";
    
    obj2.innerHTML = tempinnerHtml;
        document.body.appendChild(obj);    
        document.body.appendChild(obj2);
    }

让asp.net默认的上传组件支持进度条反映

我现在考虑的不是进度条的问题是要弹出一个模态窗体的问题用div的方式不行，因为整个文件上传的窗体都在一个updatepanel里面，所以我的fileupload控件实际是放在一个iframe里面的
