Can we use javascript in C# ?

Hi,

I want to use Javascript functionality in c#. Is it possible to use Javascript in c#? If yes how?

Can anyone provide me some guide or sample code?

Thanx

Answer 1

http://odetocode.com/code/80.aspx shows a simple dynamic JScript eval which can be called from C#, whether this is what you are looking for I am not 100% sure.

Answer 2

You can send JavaScript to the page in a number of methods.

1) You can put a literal control on your page and set the value to a script. 2) Use the ASP.NET scriptmanager to registerstartupscript.

Answer 3

For executing a javascript function on page load use,

Page.ClientScript.RegisterStartupScript(Page.GetType(), "jsstring", "urfunction()", true);

For executing on a button click event use,

ScriptManager.RegisterClientScriptBlock(urbuttonId, typeof(button), "jsstring", "urfuction()", true);

This is mostly useless but the JVM(Java Virtual Machine) has rhino a JavaScript engine. This is only mostly useless as IKVM is a Java implementation for .net including

* A Java Virtual Machine implemented in .NET
* A .NET implementation of the Java class libraries
* Tools that enable Java and .NET interoperability

allows you to use JavaScript in a very roundabout way as seen here:http://www.codeproject.com/KB/cs/EmbeddingJSCS.aspx

also Jint looks interesting.

No you can't invoke a function written in Javascript in C#.

You can, of course write C# inside an ASPX page that can invoke a Javascript function on the client page which is probably not what you are trying to do.

You can try to use JSC (jscript compiler) to compile your javascript code into a library which can then be referenced by .NET. However, jscript and javascript syntax differ, and you will more than likely be stuck having to make changes.

I ran into this problem several months ago. My solution was to port my javascript code to C# and use that.

Using the built in javascript debugging tools inside IE makes it pretty easy to do.
