For my asp.net project, I have incorporated an external javascript file. Is there a way to access the session value within this javascript file?
Appreciate any guidance on this matter!
<script>
var currentSession = '<%= Session["SessionName"].ToString() %>';
alert(currentSession)
</script>
This particular code can be implemented in Aspx. If you prefer to include it in a js.file, there are two options:
To retrieve the session variable, use the following syntax: '<%= Session["VariableName"]%>'
The text enclosed in single quotes will display the session value. 1)
<script>
var session ='<%= Session["VariableName"]%>'
</script>
2) Another way is to utilize a hidden field and set its value on the server-side;
hiddenfield.value= session["xyz"].tostring();
//Then in your script, access the hidden field like
alert(document.getElementbyId("hiddenfield").value);
This JavaScript code worked perfectly for me!
<%= session.getAttribute("variableName")%>
Hopefully it works for you too...
I have successfully implemented the following code with ASP.NET MVC 5:
var sessionData = "@Session["SessionName"]";
During the Page_Load event, the code sets a session variable called "MyTest" to a value of "abcd". It then checks if a client script named "OnSubmitScript" is already registered and if not, it registers a JavaScript function that sets the value of an HTML element with ID "TextBox1" to a combination of the session variable "MyTest" and a string "efgh".
The HTML structure includes a form with a textbox (TextBox1) that allows auto postback and a submit button.
When the form is submitted, the value entered in the textbox is stored in the session variable "MyTest" only if the textbox is not empty.
When utilizing VB as the code behind, it is necessary to utilize parentheses "()" instead of square brackets "[]".
Here's an example for VB:
<script type="text/javascript">
var accesslevel = '<%= Session("accesslevel").ToString().ToLower() %>';
</script>
let energyUnit = '@Session["EnergyUnit"]';
console.log(energyUnit);
