JQuery to achieve table interlacing color change and mouse over the two methods of color change

One, alternate color

 
$("tr:odd").css("background-color","#eeeeee"); 
$("tr:even").css("background-color","#ffffff"); 

Or one line:

 
$("table tr:nth-child(odd)").css("background-color","#eeeeee"); 

: NTH -child matches the NTH child or even element under its parent element

Two, the mouse changes color

 
$("tr").live({ 
mouseover:function(){ 
$(this).css("background-color","#eeeeee"); 
}, 
mouseout:function(){ 
$(this).css("background-color","#ffffff"); 
} 
}) 

or

 
$("tr").bind("mouseover",function(){ 
$(this).css("background-color","#eeeeee"); 
}) 
$("tr").bind("mouseout",function(){ 
$(this).css("background-color","#ffffff"); 
}) 

Of course, both live() and bind() can bind multiple events simultaneously or separately.
