在这里先说说分页的主要思路，分页limit语句和count(*)这两个你要知道之后的就是你的逻辑问题了。在这里简单的展示一下
这里展示的是连接数据库的情况，分页一页5条数据如下代码
1.HTML
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>分页</title>
</head>
<script type="text/javascript" src="./js/jquery-1.8.3.js"></script>
<body>
<form id="form1" >
搜索：<input id="search" name="search" type="text"/><input value="提交" id="btn" type="button"/>
</form>
<table id="tables"> </table>
<div id="div1"></div>
</body>
<script type="text/javascript">
$("#btn").click(function(){
var tableHtml = "<tr><th>编号</th><th>名字</th><th>价格</th></tr>";
$.ajax({
url:"hui.hui",
type:"post",
dataType:"json",
data:{"search":$("#search").val(),"page":"0"},
success:function(data){
$.each(data.arr , function(i,item){
tableHtml = tableHtml + "<tr><td>"+item.bookNumber+"</td><td>"+item.bookName+"</td><td>"+item.bookPressTime+"</td></tr>";
});
let count = parseInt(data.count)%5;
if(count>0){
count = parseInt(parseInt(data.count)/5)+1;
}
var div1="";
for(var i=0;i<count;i++){ //注，如果想一次显示几页，就循环几次，
div1 = div1 + "<a href='javaScript:void(0);' onclick="page('"+i*5+"')">"+(i+1)+"</a> ";
}
$("#div1").html(div1+"总页数："+count);
$("#tables").html(tableHtml);
}
});
});
function page(pageNo){
var tableHtml = "<tr><th>编号</th><th>书名</th><th>时间</th></tr>";
$.ajax({
url:"hui.hui",
type:"post",
dataType:"json",
data:{"search":$("#search").val(),"page":pageNo},
success:function(data){
$.each(data.arr , function(i,item){
tableHtml = tableHtml + "<tr><td>"+item.bookNumber+"</td><td>"+item.bookName+"</td><td>"+item.bookPressTime+"</td></tr>";
});
let count = parseInt(data.count)%5;
if(count>0){
count = parseInt(parseInt(data.count)/5)+1;
}
var div1="";
for(var i=0;i<count;i++){ //在这里修改开始(int i =0)和结束(i<count)，就可以达到动态分页了
div1 = div1 + "<a href='javaScript:void(0);' onclick="page('"+i*5+"')">"+(i+1)+"</a> ";
}
$("#div1").html(div1+"总页数："+count);
$("#tables").html(tableHtml);
}
});
}
</script>
</html>
分页是一个静态分页，如果想动态的就把蓝色部分循环改一下就好了

上面的内容有什么不对的地方，请大家多多指教！
