Client side Session Variables

Question

Does SharePoint support session variables that can be accessed by the client side? Using client side jQuery or JS or even placing code on an ASPX acsset attached to a webpart to set variable on the page in a web part that can be read by the jQ, JS, etc.

Answer 1

Define JavaScript variable like this:

<script type="text/javascript">
var myVariable = '<%= this.Session["VariableName"] %>';
</script>

In this example your variable will have string type. If it is e.g. integer, you don't need to use quotes ''. The idea is the same as described in this article: Pass locale of current web site (SPWeb) in SharePoint into JavaScript.

Note that you can't use this technique in separate .js files. You can only use it if JavaScript is embedded to the page as shown above. However it is not big limitation. You may define variable as shown above and pass it to the function which is defined in separate .js file.

• You may use HiddenField control to "send" value from server to client, where you can read it from JavaScript
