从模型弹出窗口获取Fileuploader的值 [英] Get Value of Fileuploader from model popup

问题描述

我有一个带有模型弹出扩展器的aspx页面。它包含FileUploader.I在上传时需要Progrss栏，但我没有得到fileuploader的值。它正在给0.Their没有单独的子页面和父页面。我用过仅在父页面上模型弹出扩展器..

I have a aspx page with model popup extender.And that contains FileUploader.I want Progrss bar while Uploading but i am not getting value of fileuploader.It is giving 0.Their are no separate child and parent page.I have used model popup extender on parent page only..

<asp:ModalPopupExtender ID="mpnlPopup" runat="server" TargetControlID="btnModalTarget"

                PopupControlID="Panel2" BackgroundCssClass="modalBackground" DropShadow="false"

                OnOkScript="onOk()" DynamicServicePath="" Enabled="True" RepositionMode="RepositionOnWindowResize"

                CancelControlID="btnCloseImage">
            </asp:ModalPopupExtender>

现在此弹出控件ID包含面板

Now This Popup Control Id contains panel

<asp:FileUpload ID="UploadImage" runat="server" Width="200px" CssClass="appfileupload" />                                            
                                                                                                     <asp:Button ID="btnUpload" runat="server" Text="Save" CausesValidation="true" ValidationGroup="CheckImage" OnClick="btnUpload_OnClick" OnClientClick="return ProgressBar()" />  
  <asp:Button ID="btnCloseImage" runat="server" Text="Close" />

现在 OnClientClick =return ProgressBar（） 转到function.bUT UploadImage.ClientID VALUE为0.如何获得此值并使我的进度条处于工作状态

Now OnClientClick="return ProgressBar()" goes to the function.bUT UploadImage.ClientID VALUE is 0.hOW TO GET THIS VALUE AND MAKE MY PROGRESS BAR IN WORKING CONDITION

<script language="javascript" type="text/javascript">
        var size = 2;
        var id = 0;

        function ProgressBar() {
            alert("in");

            var ID = $("<%#UploadImage.ClientID %>").parent.valueOf();
           alert(id);
           if (document.getElementById('<%#UploadImage.ClientID %>').value != "") {

               alert("va");
                document.getElementById("divProgress").style.display = "block";
                document.getElementById("divUpload").style.display = "block";
                id = setInterval("progress()", 20);
                return true;
           }
            else {
                alert("Select a file to upload");
                return false;
           }

        }

        function progress() {
            size = size + 1;
            if (size > 299) {
                clearTimeout(id);
            }
            document.getElementById("divProgress").style.width = size + "pt";
            document.getElementById("<%#lblPercentage.ClientID %>").firstChild.data = parseInt(size / 3) + "%";
        }

    </script>

推荐答案

（ <％＃UploadImage.ClientID％>）。parent.valueOf（）;
alert（id）;
if （ document .getElementById（' <％＃UploadImage.ClientID％>'）。value！= ）{

alert（ VA）;
document .getElementById（ divProgress).style.display = block;
document .getElementById（ divUpload).style.display = block;
id = setInterval（ progress（）， 20 ）;
return true ;
}
else {
alert（ 选择要上传的文件）;
return false ;
}

}

function progress（）{
size = size + < span class =code-digit> 1 ;
if （size> 299 ）{
clearTimeout（id）;
}
document .getElementById（ divProgress）。style.width = size + pt;
document .getElementById（ <％ #lblPercentage.ClientID％>）。firstChild.data = parseInt （size / 3 ）+ ％;
}

< / script>

("<%#UploadImage.ClientID %>").parent.valueOf(); alert(id); if (document.getElementById('<%#UploadImage.ClientID %>').value != "") { alert("va"); document.getElementById("divProgress").style.display = "block"; document.getElementById("divUpload").style.display = "block"; id = setInterval("progress()", 20); return true; } else { alert("Select a file to upload"); return false; } } function progress() { size = size + 1; if (size > 299) { clearTimeout(id); } document.getElementById("divProgress").style.width = size + "pt"; document.getElementById("<%#lblPercentage.ClientID %>").firstChild.data = parseInt(size / 3) + "%"; } </script>
