Why would you want to call client side code on the server side (I know about node.js)? This doesn't make much sense.

What is so special about this javascript function that it can't be done using MVC/JsonResult Action that you use as an Ajax call in your client side?

To me this seems like an unnecessary layer of complexity that is probably going to be the cause of many head aches for you.

I have a function drawsvg(x,y,value) in cshtml, and i want to pass these values to the javascript function to draw svg diagram.

Don't compare ASP.NET Webform with ASP.NET MVC.Please post your scenario for calling Javascript inside the server side

Store the values in to ViewData from the controller and take the viewData value from the javascript

Solution 1

//from the javascript function you can take the ViewData value like below

C#

function YouJsFunction(){

var test = '@ViewData["NAME"].ToString()';

}


//Set the viewdata value befor returning view in the ActionResult
Public ActionResult YourAction()
{
ViewData["NAME"]="Hello";
return View();

}

Hope this helps

This is single value you are passing to the view. I want to pass an arraylist<object> to the view.. :)
