    this.showPageNav = function(pagerName, positionId) {

    	var element = document.getElementById(positionId);
    	
    	var pagerHtml = '<span onclick="' + pagerName + '.prev();" class="pg-normal"> &#171 Prev </span> | ';
        for (var page = 1; page <= this.pages; page++) 
            pagerHtml += '<span id="pg' + page + '" class="pg-normal" onclick="' + pagerName + '.showPage(' + page + ');">' + page + '</span> | ';
        pagerHtml += '<span onclick="'+pagerName+'.next();" class="pg-normal"> Next &#187;</span>';            
        
        element.innerHTML = pagerHtml;
    }
}

 

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;
}
