I am getting null value from ascx file

问题

I am getting null value from Plaka .How can I solve this problem.pages created dynamically inside the ascx file .

javascript part:

   var myFunction = function()
     {
                            Vp=  #{txtPlaka}.getValue();
           $("#<%=FileUpload1.ClientID%>").uploadify('upload','*');
     };



    $(document).ready(function () {

          var Vp ="";
          $('#btnMusteriEkle').click(myFunction);

        $("#<%=FileUpload1.ClientID%>").uploadify({
            'uploader': 'Upload.ashx',
            'swf': 'uploadify/uploadify.swf',
            'script': 'Upload.ashx',
            'cancelImg': 'images/cancel.png',
            'folder': 'upload',
            'multi': true,
            'method': 'post',
            'buttonText': 'RESIM SEC',
            'fileExt': '*.jpg;*.png;*.gif;*.bmp;*.jpeg',
            'auto': false,
            'formData': { 'id': 'id', 'Plaka': Vp, 'Foo':'foooo'},
            onAllComplete: function (event, data) {

            }

        });

    });


</script>

upload.ashx file

/// I am getting null value here(pwd5).pwd1 and pwd2 is okey, ///I can catch them values

            string pwd5 = context.Request.Form["Plaka"]; 
            string pwd1 = context.Request.Form["Id"];
            string pwd2 = context.Request.Form["Foo"];

and here is the markup syntax

<ext:TextField ID="txtPlaka" runat="server" FieldLabel="Plaka" Flex="1" AllowBlank="false" ClientIDMode="Static">
        </ext:TextField>


 <ext:Button runat="server" ClientIDMode="Static" ID="btnMusteriEkle" Text="Yeni müşteri ekle">
          <Listeners>
           <Click Handler="
          $('#FileUpload1').uploadify('upload','*'))">  
          </Click>
           </Listeners>
    </ext:Button>

Here is the my logic I followed: first inside the ready function created var Vp="";later bind the function called myFunction, later, run the uplodify function.when the user clicked the button, this binding already defined ($('#btnMusteriEkle').click(myFunction);), directly run the myFunction and asigned Vp value as #{txtPlaka}.getValue();and run uplodify() function, those value(Vp), should pass the uploadify function but so far, nope doesn't work.

回答1:

Gonna take a wild guess here, i don't know much about ascx files.

Question: Is this the part you use to upload?

    $("#<%=FileUpload1.ClientID%>").uploadify({
    'uploader': 'Upload.ashx',
    'swf': 'uploadify/uploadify.swf',
    'script': 'Upload.ashx',
    'cancelImg': 'images/cancel.png',
    'folder': 'upload',
    'multi': true,
    'method': 'post',
    'buttonText': 'RESIM SEC',
    'fileExt': '*.jpg;*.png;*.gif;*.bmp;*.jpeg',
    'auto': false,
    'formData': { 'id': 'id', 'Plaka': Vp, 'Foo':'foooo'},
    onAllComplete: function (event, data) {

Meanwhile try this:

var upload;
var myFunction = function()
 {
       Vp=  {txtPlaka}.getValue();
       upload()
 };



$(document).ready(function () {

    var Vp ="";
    $('#btnMusteriEkle').click(myFunction);

    upload = function(){
        $("#<%=FileUpload1.ClientID%>").uploadify({
        'uploader': 'Upload.ashx',
        'swf': 'uploadify/uploadify.swf',
        'script': 'Upload.ashx',
        'cancelImg': 'images/cancel.png',
        'folder': 'upload',
        'multi': true,
        'method': 'post',
        'buttonText': 'RESIM SEC',
        'fileExt': '*.jpg;*.png;*.gif;*.bmp;*.jpeg',
        'auto': false,
        'formData': { 'id': 'id', 'Plaka': Vp, 'Foo':'foooo'},
        onAllComplete: function (event, data) {

        }

    });
  }

});
