本人刚学jquery,以前一直用mootools。现要对一个id为t1的table中的所有tr添加mouseenter和mouseout事件，我是这样弄的，但是有错误：
function HighLightTR(color,objId)
{
var trBgcolor;
var ArrTR = $(objId+" tr");
ArrTR.each(function(index,element){
element.mouseout(function(){
element.css('background-color','red');
});
element.mouseenter(function(){
element.css('background-color','blue');
});
}); return ArrTR;}
function HighLightTR(color,objId)
{
var trBgcolor;
var ArrTR = $(objId+" tr");
ArrTR.each(function(index,element){
element.mouseout(function(){
element.css('background-color','red');
});
element.mouseenter(function(){
element.css('background-color','blue');
});
}); return ArrTR;}
{ var trBgcolor; var ArrTR = $(objId+" tr");
ArrTR.each(function(index,element){$(element).mouseout(function(){$(this).css('background-color','red');
});
$(element).mouseenter(function(){
$(this).css('background-color','blue');
});
}); return ArrTR;}
试试
http://download.csdn.net/detail/p2227/3936926另外你只给出函数是不全面的，相关的HTML也要有最后，jQuery中根据ID获取DOM是$("#id")
$(function(){
$("#t1 tr").hover(function(){
$(this).css('background-color','red');
},function(){
$(this).css('background-color','blue');
})
});
