Any way to pass an object from c# code behind to javascript?

Question

I want to pass an object from my c# code behind to my javascript. I know that I can use

var myVar = '<%# myVar %>' 

to pass variables. However, that method seems to pass everything as a string. I want an object.

Is there any way to accomplish that?

Answer 1

You can serialize it to JSON using the JavaScriptSerializer.

Something like:

System.Web.Script.Serialization.JavaScriptSerializer oSerializer = 
         new System.Web.Script.Serialization.JavaScriptSerializer();

string sJSON = oSerializer.Serialize(myVar);

Then you in your aspx code you can use:

var myVar = <%# sJSON %>; 

Which will output something like:

var myVar = {"Name":"John","Age":"30","ID":"111"}; 

Answer 2

Use JSON serialization to convert a .NET object into JS which can be deserialized into an object (or, exec'd into an object).
