for(var i=0;i<names.length;i++){
//创建li标签
var liobj=document.createElement("li");
//添加li中的文本

//将li放入ul标签中
ulobj.appendChild(liobj);
liobj.onmouseover=onmouseoverHaddle();
liobj.onmouseout=onmouseoutHaddle();
}
}
function onmouseoverHaddle(){
this.style.backgroundColor="red";
}
function onmouseoutHaddle(){
this.style.backgroundColor="#fff";
}
</script>
