Get ID of Previous Table in the DOM issue

When i use the fn below it returns the current table as previous..

I "tweaked" the index in the slice to get the results I was looking for. This is a hack and I am looking for explanation/answer if there is something I am missing.

Each tables is nested in a div or 2. But using the selector I would assume the previous would be the previous of the selector specified.

hack: ? $all.slice(0, $all.index(this)-10).reverse() : $all.slice($all.index(this) + 2)

original func:

$.fn.reverse = function () {
    return this.pushStack(this.get().reverse(), arguments);
};

// create two new functions: prevALL and nextALL.
$.each(['prev', 'next'], function (unusedIndex, name) {
    $.fn[name + 'ALL'] = function (matchExpr) {
        // get all the elements in the body, including the body. 
        var $all = $('body').find('*').andSelf();

        // slice the $all object according to which way we're looking 
        $all = (name == 'prev')
             ? $all.slice(0, $all.index(this)).reverse()
             : $all.slice($all.index(this) + 1)
        ;
        // filter the matches if specified 
        if (matchExpr) $all = $all.filter(matchExpr);
        return $all;
    };
});

elements: these are looped, I am trying to navigate from one table to the next using up, down, left right arrow keys.. and need to be able to get the ID of the previous & next table

                    "<div id='divOuter" + div.divCode + "' class='BoxOuterDiv' >"
                    + " <div id='div" + div.divCode + "' class='BoxDiv' >"
                    + "         <table class='grid' id='" + div.divCode + "' width='100%'>"

                    + "                     <span id='spn0" + div.divCode + "' class='rgCollapse' onclick='Collapse(this)'>&nbsp&nbsp</span>"
                    + "                     Division: " + div.divCode
                    + "                 </td>"
                    + "                 <td class='col1' width='5%' style='padding-left:15px' nowrap='nowrap'>"

Credit to Author: jQuery to find all previous elements that match an expression

Another question.. This blows up in IE! any idea why??

$.fn.reverse = function () {
return this.pushStack(this.get().reverse(), arguments);

};

// create two new functions: prevALL and nextALL. $.each(['prev', 'next'], function (unusedIndex, name) { $.fn[name + 'ALL'] = function (matchExpr) { // get all the elements in the body, including the body. var $all = $('body').find('*').andSelf();

    // slice the $all object according to which way we're looking 
    $all = (name == 'prev')
         ? $all.slice(0, $all.index(this)-10).reverse()
         : $all.slice($all.index(this) + 2)
    ;

    // filter the matches if specified 
    if (matchExpr) $all = $all.filter(matchExpr);
    return $all;
};

});

try

$("table").parent("#divOuter").prev("#divOuter").find("table"); //up one

$("table").parent("#divOuter").next("#divOuter").find("table"); //down one

also i would change your ids to classes if you are looping as only 1 unique id is allowed per page.
