[jQuery] Re: jQuery newbie - working through Learning jQuery book

[Karl Swedberg]

Ooops. Yeah, that second one was originally a .gt(), so we should  
leave it as .slice( (currentPage + 1) * numPerPage - 1)

That little chunk of code should look like this:

    $table.bind('repaginate', function() {
      $table.find('tbody tr').show()
        .slice(0,currentPage * numPerPage)
          .hide()
        .end()
        .slice((currentPage + 1) * numPerPage - 1)
          .hide()
        .end();
    });

Hi Karl,

Thanks, that did help in getting the links to work correctly.

However, the new code (with slice) isn't working for displaying only
10 rows per page.
I'm using the downloaded page and tables.js code (with the slice
modifications) from the Learning jQuery website, not my own code.

On page 1, all rows are shown, on the page 2, rows 20 through the end
of the list display, on page 3, rows 30 through the end of the list
display, you get the idea.

Any thoughts?

Hi there,

Sorry about the confusion with the API change. If you're replacing
the .lt() method, you're going to need to use 2 arguments with
the .slice() method, with the first argument being 0.

So, try .slice(0, currentPage * numPerPage) instead.

That will select the elements with an index between 0 and the value  
of
currentPage* numPerPage

Same goes with the other slice:

      .slice(0, (currentPage + 1) * numPerPage - 1)

Hope that helps.

I'm working my way through chapter 7 of the Learning jQuery book,  
and
encountered issues with .lt and .gt. After discovering that .lt
and .gt had been deprecated in the current release of jquery, I
replaced the sample code with the slice method.

However, I have had no luck getting:

1. the page to display only 10 rows of a table on each page
2. getting more than one page to display (none of the links for  
pages
1-7 work)

Has anyone worked their way through the table sorting/pagination  
code
in chapter 7?
Here's the code I used, which is not working:

var repaginate = function () {
  $table.find('tbody tr').show()
     .slice(currentPage * numPerPage)
        .hide()
     .end()
     .slice((currentPage + 1) * numPerPage - 1)
         .hide()
  .end();
};
