jQuery counter question

I have a table and i want to count how many tr i hide.

The code:

<rich:jQuery query="ready(function() {
var i = 0;
jQuery('#inbox:_inboxTable_').find('span[title=isArchivedStatusPlusIncludeArchive]').each(function(i, o){
        if (jQuery(this).text() == 'true+false' ){
                i++;
                alert(i);
                jQuery(this).parent().parent().parent().fadeOut();
        }
    jQuery('#inbox').find('span[title=documentProccesedCountTitle]').html(i+' documents are beeing processed to be remove开发者_如何学Pythond from the inbox');
});
})"/>

For a page with 10 tr, in my test 7 are hidden by this part of code but 'i' is 10 instead of 7 at the last step...

I just have no clue...why? Does anyone see the reason?

Thanks in advance.

What about:

$("#table_id tr:hidden").length

i=10 because you are using it as an index of the function, try using j or something else:

jQuery('#inbox:_inboxTable_').find('span[title=isArchivedStatusPlusIncludeArchive]').each(function(j, o){
...
}

Also, instead of using jQuery(this).parent().parent().parent().fadeOut(); you could use the closest jQuery(this).closest('tr').fadeOut(); (if the tr is your target).
