jquery background color change on button click

Question

Why doesnt this work?

jquery

$("#button").click(function(){ 
 $("go").css("background-color","yellow");
 });

html

<table><tr id=go bgcolor=#010609><td>hello</td></tr</table>
<input type=button id=button>

Answer 1

go is an id :

$("#button").click(function(){ 
    $("#go").css("background-color","yellow");
});

Answer 2

Your selector for go is wrong.

Try

$('#go').css({backgroundColor: 'yellow'});
