are these variable values same that you are setting in your Ajax call, or you are receiving them as Ajax response?

Both variables come from a different page. I want to initiate the variable in javascript before i make ajax call.
what do you mean by 'different page'?
if you are able to use the value in Ajax call, there is no reason that you can't put that in a javascript variable.
Just tell me from where you are getting these values and in what format (which line of code?).

My 'different page' is a product list: www.something.com/product. I want to edit a product with id = 87, so when I clicked the link, it pointed me to www.something.com/product/87.
I want to make sure that I can retrieve the productid (87) from url before I make update by ajax call to my product's table.

My url is not in variable. How to get url value using javascript?
var url = "www.something.com/product/87";
var productId = url.substring(url.lastIndexOf("/")+1 );
just the way you are getting it now
var url = "<?php echo site_url('/product/additem
var url = "<?php echo site_url('/product/additem
ASKER
var url = "<?php echo site_url('/product/additemI can't set like this way, because my page haven't know yet what productid will be set.'); ?>";
your page will know by the time it is loaded into the browser.
Otherwise you need to tell me that from where i will get the information
