Calling C# code method with parameters in javascript using razor

Question

I am trying to call a C# method in my javascript code and also trying to pass parameter to it using razor syntax but not able to do it correctly. Below is my code:

function RecallNoFmatter(cellvalue) {
    var value = @(Precall.S300FormatRecall(+cellvalue+));
    return value;

}

I get this error message:

Compiler Error Message: CS0103: The name 'cellvalue' does not exist in the current context.

Can someone tell me the correct syntax of how to pass parameter in above?

Answer 1

C# runs server-side. The @ code is running server-side before the script is delivered to the client and has no access to the JavaScript values.

Your JavaScript runs client-side and has no ability to call server-side methods.

If you want to expose server-side functionality to the client, you're going to have to use AJAX and provide some service for the client to call.
