Server side session in asp.net
Question:
Tag: asp.net,web-services,session
I want to set one value in server side session in client side and need to access that session in web service, so i tried below
In client side :
//Set the server side session like below
var vr_="demo.png";
'<%Session["path"] = "' + vr_ + '"; %>';
//In alert,checked the server side session value like below
alert('<%=Session["path"] %>');
the value getting in alert is fine and i called the web service but when try to access the session in web service i am getting the following as session value
' + vr_ + ' not the original value "demo.png"
Please find the source code below,
In Javascript :
var vr_="G:\\13-06-15-demo\\app1\\uploads\\demo.png"
In Jquery ajax request, i called the webservice like below
$.ajax({
url: "../webservice/email.asmx/senmail",
data: "{'tomail': '" + tomail + "','subject': '" + subject + "','message': '" + message + "','attachment': '" + vr_+ "'}",
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
In web service, the method is like below
public bool senmail(string toMailId, string subject, string message,string attachment)
{
Answer:
You've got a quotes problem, fix it like this:
<% Session["path"] = "'" + vr_ + "'"; %>
EDIT 1:
Javascript and ASP.NET are not the same, so you cannot access the variables, so you can't do it on the client side. You must send something to the server like a POST request using Javascript or easier using jQuery.
Here are some resources:
Using AJAX and Javascript:
http://www.w3schools.com/php/php_forms.asp http://www.w3schools.com/ajax/ajax_xmlhttprequest_send.asp
jQuery AJAX: http://api.jquery.com/jQuery.ajax/
http://api.jquery.com/jQuery.post/
EDIT 2:
The answer was to create a normal javascript object/array and then convert it to JSON using JSON.stringify(), like seen in this example: Jquery Ajax Posting json to webservice.
JSON.stringify(): https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify
