<style type =“text / css”media =“print”>和jQuery？

Question

I have a site where the HTML is just a mess (generated by SharePoint designer).

I need to print the the page, but it looks like crap in IE7/8 print preview, so I need to use <style type="text/css" media="print"> to alter some tables, divs etc, but a lot of the elements have no class or ID. Is there a way to use the print stylesheet and jQuery together to find elements? When I search on Google, most of the links are about switching stylesheets.

Thanks in advance.

You could use jQuery's powerful selectors to actually ADD classes that you might need, which will then be accessible from your print stylesheet.

For example.

$("p:last-child").addClass("last-para");
$("tr:odd").addClass("odd-row");
$("table:eq(5)").addClass("table6"); // 6th table, starting from a 0 index!

Just for fun, here's some jQuery magic that will add a class (numbered) to all your tables AND all your rows within a table.

$("table").each(function(index, value) {
    $(this).addClass("table" + index);
    $("tr", this).each(function(index, value) {
        $(this).addClass("row" + index);
    });
});

If you need help with specifying particular elements, post them in your question and we'd be happy to help.
