How to pass a variable value from the code behind to an external JavaScript file (jQuery file)?

Question

Suppose I have this:

<asp:LinkButton runat="server" CssClass="lFilename" ID="grdlinkFilename" Text='<%#Eval("FILEPATH")%>' CommandArgument='<%#Eval("FILEPATH")%>'  OnCommand="grdlinkFilename_click"> </asp:LinkButton>

How can I pass the <%#Eval("FILEPATH")%> to an external JavaScript (jQuery) file?

You can take help of html tage data-id to do this.

 <asp:LinkButton runat="server" CssClass="lFilename"
 ID="grdlinkFilename" Text='<%#Eval("FILEPATH")%>'
 CommandArgument='<%#Eval("FILEPATH")%>' 
 OnCommand="grdlinkFilename_click" data-id='<%#Eval("FILEPATH")%>' >
 </asp:LinkButton>

and in Jquery you can get that value as

var result = $("#grdlinkFilename").attr("data-id");

Thank you for this. Let me try this.

Hi I tried it and I know it should work. But for some reason it not. I believe it's because of the way I convert the address. For example filepath = "d:\folder\image.jpg" In my Jquery file I try to change it this way var result = $("#grdlinkFilename").attr("data-id"); result = result.replace("D:\\", "wwwsite/VirtualDrive/"); result = result.replace("\\", "/");

Add I'm editing my JQuery file directly from Visual Studio 2008.

I could'nt understand what you really want to do with address that you are getting from data-id ? Could you plz elaborate this so that I can get the point you want to get ?

Is this what it is you need ?

HTML

   var valueLink = document.getElementById('grdlinkFilename').innerText

ASP

   var valueLink = document.getElementById('<%=grdlinkFilename.ClientID %>').innerText

What is the output of this code is it the value of "filepath"?

Mehdi Bugnard Over a year ago

this example, you should just return the value 'Filepath' attribute text. It should work. Have you tried?

I have an external javascript(jquery) file. What I want to do is to pass the value of <%#Eval("FILEPATH")% to my external js file.

You can pass it using different state management available in ASP.NET and out of it. For ASP.NET "specific" state management , can have a look on good description on :

A Beginner's Tutorial on ASP.NET State Management

Or, simply assign value to some UI element with display:none,and read it's value from javascript.
