How can i Get a Another Form Session Value in Java Script File Using ASP.Net?

Question

am having Sample.aspx and sample.js both are in different directory.

how can i get the Sample.aspx page session values in sample.js file ?

i cant get the value for the following types

    function session() {
        alert('<%=Session.getAttribute("hdn_CheckedData")%>');
        alert(document.getElementbyId("hdn_CheckedData").value);
        alert('<%=Session["CheckedData"]%>');
        alert('<%=Session("CheckedData")%>');
        alert('<%=Session["CheckedData"].ToString()%>');
        alert('<%=Session("CheckedData").ToString()%>');

One simple solution is to declare the session variables just before the load of your javascript file and inside the aspx page. Eg on sample.aspx you have

<script>
var sessionCheckData = "<%=session["CheckedData"].ToString()%>";
</script>
<script type="text/javascript" src="sample.js"></script>

and on sample.js you have

  function session() {
        alert(sessionCheckData);
    };

I don't think backticks are valid wrapper for JavaScript strings. confirmed.

@ShadowWizard I Lost you. What I am try to say here is the inside the javascript can not render the session variable, so can he render it before.

Andy T Over a year ago

While @ShadowWizard's solution will work, it makes the script dependent on a "global" variable that session.js does not if it will provided. I would recommend that rather than set the variable, why not simply pass it in as a parameter to the session() method?

user447356 Over a year ago

@QuetiMporta you miss the point; JavaScript can't directly read session variables and you can't have <%= in .js file since it's not parsed by the server.

Andy T Over a year ago

You are correct, however, you can still pass in the session variable by embedding it as the parameter to session()... <script type="text/javascript" src="sample.js"></script><script> session("<%=session["CheckedData"].ToString()%>"); </script>

You can save the session data to a hidden field on your page. After that you have direct access to that field in you js file.

Or you can declare a session variable as Aristos has proposed. That would more straightforward actually.

I would write a generic handler and use JSONP to pass any data to external Javascript.

Please take a look at here, here and here.

Since it is not cross domain, JSON should also work.
