Javascript access to a Java object

[Marilyn de Queiroz]

I have a Java object on my JSP page
<% Object javaObject = myClass.getJavaObject(); %>

Can my JavaScript script access javaObject? How would it reference it?

i dunno if will work with jsp, but there is a library called rhino, which has some bridging between java & javascript

The only way that JavaScript can access Java is either having Java Write the information to the page in some format that the JavaScript can decipher, post the page back to the server, or using Ajax ro communicate with the server.

What if I put the text in a sentence on the page like:

The status of the object is <%= javaObject.getStatus() %>.

Can I get a word out the the sentence if the sentence is not in a form? What if the sentence is in a table? If I can't get a 'word' out of the sentence, could I somehow get the whole sentence?

I'm trying to do a "confirm", but only in the case where the object has a certain state and not on every 'submit'.

You could do it as simple as:

<script type="text/javascript">
  var status = "<%= javaObject.getStatus() %>";
  alert(status);
</script>

or as complicated as:

<span id="spanStatus"><%= javaObject.getStatus() %></span>
<script type="text/javascript">
  var status = document.getElementById("spanStatus").innerHTML;
  alert(status);
</script>

Thanks, Eric.

I'm stuck again.
I'm trying to do something like this:

onSubmit:

var inputFromForm = getInputFromForm();
var state = <%= javaObject.getStatus( inputFromForm ) %>
alert( "The status of the object is " + state )

Is it possible to use the input from the form in the jsp tag?

(I also seem to be having problems getting my input from the form, but if I can't even use the input, I'm not going to worry about that right now.)

[Eric Pascarello]

var state = "<%= javaObject.getStatus( inputFromForm ) %>"
alert( "The status of the object is " + state )

think you may need the quotes around it....
If that does not work do a view source after the page has been rendered and see if what is being written to the page is what you wanted to appear. Are you getting an error? If so what does it say?
