Add border on mouseover

I want to have a table border (which I can set using css, rather than the inline border= attribute) to be set to border: 1px solid black; when I mouseover the table.

How do I go about doing this in jQuery. I think it's identical to what's happening to the buttons at the top of this page (Questions, Tags, Users etc) except that is a div having it's background color changing whereas I want to change the border of a table. But the concept is the same.

Alternatively, "outline" as opposed to "border" will not take up extra space in the element layout.

It may be better to swap classes on the table instead of editing the CSS properties directly - that would be a more scalable/extendable solution:

table {
   border:0;
}

table.border {
   border:1px solid #000;
}

Of course your table will 'jump' in position 1px when the border is added so maybe it's better to use margin or a white border when you are not hovering:

table {
   border:1px solid #fff;
}

table.border {
   border:1px solid #000;
}

Or best yet, if you don't need to be compliant with IE6 you can do it all with pure CSS:

table {
   border:1px solid #fff;
}

table:hover {
   border:1px solid #000;
}

This would be the best/simplest/scalable approach!

For hovering effects, jQuery provides the hover() pseudo-event, which behaves better than moueseenter/mouseleave. Also, it's a good idea to create a CSS class for each state (normal and hovered), and then change the class on hover:

$(document).ready(function() {
    $("#tableid").hover(
        function() { $(this).addClass("Hover"); },
        function() { $(this).removeClass("Hover"); }
    );
});

Your CSS could look like this:

table.Hover { border: 1px solid #000; }

Check out this article on the mouseenter and mouseleave events.

$("table#mytable").mouseenter(function(){
      $("table#mytable",this).css("border", "solid 1px black");
    }).mouseleave(function(){
      $("table#mytable",this).css("border", "o");
    });
