Read JavaScript array values in Java class

I have an application where
1) Objects are added in JavaScript Array.
2) After form submission, this Array needs to be accessed in Java and the contents of the Array needs to be read in Java class.
3) The GUI user can use ","(comma) while providing the input. Therefore I cannot separate the elements in Array using ","(comma) as delimiter in Java class.
Is there a way to assign the value in JavaScript variable to a Java Variable in the JSP and then pass this Java variable to Java class, instead of JavaScript Array.
e.g.
var arrType= new Array();
for( i = 1; i < document.all.tblContent.rows.length; i++)
{
arrType[i-1] = document.all.tblContent.rows[i].cells[1].innerText;
}
Now, this "document.all.tblContent.rows[i].cells[1].innerText" can contain any character.
So, if I pass the "arrType" to Java Class, how can I separate out the elements in arrType inside Java class.

Note: document.all is outdated and IE only so do not use it. Instead use document.getElementById("theId"). Also innerText is IE only so you need to use innerHTML.

Now why don't you join the informaiton with something other then a comma then such as a pipe |.

so

document.FormName.elementName.value = arrType.join("|");

If you absolutely cannot join the elements with some odd character like pipe (|) or tilde (~) because those characters may appear in the data, your best bet would be to create multiple hidden elements each with the same name. You will then be able to retrieve them as a string array on the back end.

In fact, that's the way I'd do it any case.

Can u explain this in little more detail?. I also have same problem. I need to get a String array in server. I also wanna avoid using 'odd characters' to separate values. I want to send value from a javascript array to the server and from server i need a java string array. I use Struts.

Thanks

If you have a construct such as:

<input type="hidden" name="xyz" value="1"/> <input type="hidden" name="xyz" value="2"/> <input type="hidden" name="xyz" value="3"/> <input type="hidden" name="xyz" value="4"/>

You can use

String[] values = request.getParameterValues( "xyz" );

on the server side to get the string array of values.

The order is non-deterministic, however.

Kewl..BB, and dont take rest. I'll come back with some more tommorow(Same thread).

Thanks.
