Can see that you already passing regid as querystring to open your popup ? Are you looking to pass multiple query strings? can you make the question clear?

Thats because you are not passing the parameter to your JS method call . Pass the clientid of your label to the calling code and handle the value of the label in the JS function

TrushnaK 29-Nov-13 2:00am

you havent pass value to javascript Demand(regid) through onclientclick='Demand()'.

Solution 1

Hi Parmendra,

based on my understanding or ur problem i have come with one solution..

i guess it will work for your requirement...

Note these things:

i dont know why you r making the label as invisible.
if it is invisible , it wont render in the browser, then u wont get the value of it...
instead u can use a hidden field to store in the browser...

XML

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <script src="jquery-1.10.2.min.js" type="text/javascript"></script>
   <script type="text/javascript">

       var Demand = function () {
           var Label1 = document.getElementById('Label1').innerText;
           debugger;
           window.open("AddM.aspx?Id=" + Label1, 'Define', 'width=1000,height=600,left=0,top=0,scrollbars=yes,resizable=yes,menubar=yes');
           return false;
       }


    </script>
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <asp:Label ID="Label1" runat="server" Text="12313322" Visible="true" />
    <br />
     <asp:Button ID="AddM" runat="server" Text="Add Medicine" CssClass="nm"
        onclientclick='return Demand()'   />
    </form>
</body>
</html>

XML

<script type ="text/javascript">
    function Demand() {
        var regid = $('#<%=Label1.ClientID%>').html();
        window.open("AddM.aspx?Id=" + regid, 'Define', 'width=1000,height=600,left=0,top=0,scrollbars=yes,resizable=yes,menubar=yes');

Solution 3

Problem

1. You have set Visible = "false" for that Label. So, it will not render on Browser. Instead do style = "display:none;".

ASP.NET

<asp:Label ID="Label1" runat="server" Text="Label" style="display:none;"></asp:Label>

Now, it will render but will be hided. So, you can get its value.

2. You are not sending any value on function call inside the Button onclientclick='Demand()'. But you are reading the parameter regid, which will always by undefined.
As you are trying to read the Label's value, so don't pass any parameter. Directly read its value in function like below...

XML

<script type ="text/javascript">
function Demand() {
    var regid = document.getElementById('Label1').innerText;
 
    window.open("AddM.aspx?Id=" + regid, 'Define', 'width=1000,height=600,left=0,top=0,scrollbars=yes,resizable=yes,menubar=yes');
}
</script>

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 29-Nov-13 2:37am

Can you debug and see what is the value of regid inside the function.

Just do like below...

function Demand() {
debugger;
var regid = document.getElementById('Label1').innerText;

window.open("AddM.aspx?Id=" + regid, 'Define', 'width=1000,height=600,left=0,top=0,scrollbars=yes,resizable=yes,menubar=yes');
}

Parmendra choudhary 29-Nov-13 4:29am

no solution same error
http://localhost:2193/Web/OutPatient/AddM.aspx?Id=undefined

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 29-Nov-13 5:31am

I am asking- what is the value of Label when you hit the debugger.

Parmendra choudhary 29-Nov-13 5:34am

when debugger go there the value show is undefined

Parmendra choudhary 29-Nov-13 5:36am

Level1 also filled by initial querystring, Is it problem

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 29-Nov-13 5:42am

Can you show the code where you are setting the Lable Text?
Have you removed Visible = "false" property from that Label?
Otherwise, it will not work.

Parmendra choudhary 29-Nov-13 5:55am

sir my level is ............

<asp:Label ID="Label1" runat="server" Text="12313322" Visible="true" />

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 29-Nov-13 5:38am

Now try like this...

Just do like below...

function Demand() {
var regid = document.getElementById('<%= Label1.ClientID %>').innerText;

debugger;

window.open("AddM.aspx?Id=" + regid, 'Define', 'width=1000,height=600,left=0,top=0,scrollbars=yes,resizable=yes,menubar=yes');
}

Parmendra choudhary 29-Nov-13 5:47am

popup window will not open when we use this code

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 29-Nov-13 8:01am

Do you understand what I am asking you to do? I am asking you to debug and see what is the value of that Label inside function.

Make sure that Label is Visible.

Parmendra choudhary 29-Nov-13 8:04am

sir your code is all right but its not work on Mozila......when a debug the level show null value, When i use crome its work correctly

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 29-Nov-13 8:12am

Okay try like below... User innerHTML.

var regid = document.getElementById('<%= Label1.ClientID %>').innerHTML;

Change
var regId = document.getElementById('Label1').innertext;
to
var regId = document.getElementById('Label1').textContent;
it will work fine

Instead of using InnerHtml Use value Property of control in your js function
try this hope this will help you

XML

<script type="text/javascript">
var Demand = function () {
    var Label1 = document.getElementById('Label1').value;
    debugger;
    window.open("AddM.aspx?Id=" + Label1, 'Define', 'width=1000,height=600,left=0,top=0,scrollbars=yes,resizable=yes,menubar=yes');
    return false;
