java code in javascript

Hello:

I'm new to javascript. I have a JSP page which has Javascript inside it. Could I put the java code like create an object in Javascript? I try to
do it, but I cannot get the result I excepted.

Thanks in advance!

You can use JSP to write JavaScript code, just like you'd do it with HTML.
Remember that JSP runs in the server-side, while JavaScript runs in the browser (client-side).

The following script should work:

<script> function foo() { alert("<%= aJSPVariable %>"); } </script>

Suppose aJSPVariable is the String "Bar". The code's output would be:

<script> function foo() { alert("Bar"); } </script>

JavaScript objects do exist, but they're not commonly used. A JavaScript "class" has the same syntax as a JavaScript "function".

function myObj() { this.propertyOne = 2; this.propertyTwo = 4; this.toString = new Function("return ('myObj\\\'s toString method');"); }

This is advanced JavaScript stuff and, like I said, not frequently used. Since you're a beginner, I think you should focus on learning basic JavaScript and creating dynamic scripts with JSP or Servlets.
