如果要实现美观效果 可自己加入css

实例扩展如下

相应css代码

 

#pageNavPosition{
    margin: 20px 0 0;
    padding: 3px;
    text-align: center;
}
.pg-normal {
	border: 1px solid #DDDDDD;
	cursor:pointer;
	color: #61AF3F;
	margin-left: 2px;
	padding: 2px 5px;
	text-decoration: none;
}
.pg-selected {
	background-color: #A1D888;
	border: 1px solid #B2E05D;
	color: #638425;
	padding: 2px 5px;
	cursor:pointer;
