JAVA自創分頁方法

頁面：

<!-- /頁碼 -->
<div class="pages" style="margin-top:30px;border: 0px solid black;">
	<div class="page-panel" style="border: 0px solid black;width: 100%;text-align: right;margin-top: 30px;">
		<div style="float: right;">
			<a href="javascript:searchOrder('previousPage')" class="prev on">上一頁</a>
			<a href="javascript:searchOrder('netPage')" class="next on">下一頁</a>
			<span>共10條</span>
			<span>跳到</span>
			<input type="text" name="pageIndex" id="pageIndex"/><span>頁</span>
			<a href="javascript:searchOrder('pageText')" class="next on">GO</a>
		</div>
	</div>
</div>

js:

$(function(){
	searchOrder(null);
});

function searchOrder(type) {
	var pageIndex=null;
	if(type=='pageText'){
		pageIndex=$("#pageIndex").val();
	}
	$.ajax({
		url : "${APP_PATH}/jewelry/queryProContller.do",
		type : "POST",
		data : {"type":type,"pageIndex" : pageIndex}, //當前頁面
		dataType : "json",
		success : function(data) {
			var html = "";
			if (data.success) {
				$.each(data.queryproList, function(i, procoll){
					$.each(procoll, function(j, proList){
						 html +="<div style='width:200px;height:250px;background-color: #f9f8f8;float: left;margin-right: 30px;margin-top:10px;margin-left: 5px;'>";
						 html+="<center>"
						 html+="<div style='width:100%;height:200px;;border: 0px solid black;' οnclick='productCommodity("+proList.pid+")'>";
						 html+="<img alt='圖片'  src="+proList.pro_imgs+" width='100%' height='100%' >";
						 html+="</div>";
						 html+="</center>";
						 html+="<span><b>"+proList.pro_name+"</b>&emsp; <b>￥:</b><b style='color:#d9ac80;'>"+proList.pro_price+"</b></span>";
						 html+="</div>"; 
					});
				});
				 $("#proList").html(html); 	
			} else {
				return;

		}
	});
