Question

Can someone please explain to me how the data passed to jquery object, so it’s then accessible from jquery.

I.E.:

PHP script:

// $isrc variable is added by me to existing grid..
    $isrc = isrc();
    $grid->isrc = $isrc;
    $grid->load();

object declared in js:

$.fn.loadGrid = function(user_opts) {
        return this.each(function() {

            // setup DEFAULT options
            var opts = $.extend({
                order_by : "",          // sql order by
                .....
            },user_opts);
            var $grid = $(this);
            ..some stuff to do....
        });
    }
    ... some additional function to call....
});

so how do i access $isrc data?
calling it after:

        var $grid = $(this);
        var isrc = $grid.data().isrc;

comes back as unidentified…

sorry i’m quite new to object oriented programming, although i did study Java and VB few years ago..

or at lease give me a link to a tutorial re subject?..

You have to pass the value from PHP to jQuery then do whatever you want with it.
You want to echo the value in php (Ideally in a JSON format). Then use jQuery $.ajax to call the page, get the data and then do whatever you want with it in javascript.
