Question

I want to send a string I built using the StringBuilder to the HTML page, which then I want to use in my JavaScript code.

Right now here’s what I am doing:

On the client side:

<div id="data">
    <asp:Literal ID="Literal1" runat="server"></asp:Literal>
</div>

In my JS block:

var data = $("#data").html();

In the code behind:

Literal1.Text = strXml.ToString();

The thing is, this data can be seen by going through the source of the data div, which I dont want to allow.

I want this string as soon as the page loads, so I guess making an AJAX call after the page has loaded to the server is out of the way.

Any smoother way ?

It’s a .NET rookie here.. 🙂

Answer 1

you can save your string in an HiddenField then read its value using javascript something like this

<asp:HiddenField runat="server" ID="MyHidden">

in code behind

MyHidden.Value = strXml.ToString();

javascript

var data = $('#<%=MyHidden.ClientID%>').val();

or you can define strXml as protected variable and use it inside .aspx like that

public class _MyPage:Page
{
    Protected String strXml;
    private void Page_Load(Object sender,EventArgs e)
    {
         StringBuilder mystrBuilder = new StringBuilder();
         //append some text to mystrBuilder
         strXml = mystrBuilder.ToString();
    }
} 

javascript code will like this

 var data = '<%=strXml%>';
