Assigning JavaScript variable to a Java String variable

I am trying to assign an element of a JavaScript two dimensional array to a Java String variable. The element is a number but I want to assign it as a string but as there's no JavaScript string datatype it seems to cause problems. This variable must be contained in a Java String variable as we are using WebSphere classes and it will not accept it otherwise.

Here is an example of what I'm trying to do:

String content=two_dim[0][6];

two_dim is my JavaScript array.

Any help would be appreciated.

Hi Noelle,

I think that's not possible assign Javascript variables to Java variables, cause Java runs on server and Javascript in local. So, you can not exchange values.
In the other way, however, you can assign Java variables to Javascript variables. In JSP files would be like this:
'var a = <%=javaVar%>;'

I have since found a way around our problem - as the value we need is in a JavaScript array - and we want to pass it in through a form - I used

var content=two_dim[0][6];

document.forms[0].CatEntryId.value=content


This actually works - but thanks for the suggestions anyway.

They are correct, you just found another way to overcome your problem (with the exact scenario not mentioned in the question). IMHO the answers are correct for the question you gave us.

Personally I don't care much what ever you do. However, if you feel none of the above helped you in any way I suggest you delete this question.
