使用JSON实现分页可直接用
Fenye.html
<!DOCTYPE html> <html> <head> <title>JSON分页</title> </head> <body> <script type="text/javascript"> function getPageList(pageno){ var req=new XMLHttpRequest(); req.open('get','./JSON_Fenye.php?pageno='+pageno); req.onreadystatechange=function(){ if(req.readyState==4 && req.status==200){ //将传来的字符串转化为对象 eval('var info='+req.responseText); var str='<tr><th>ID</th><th>姓名</th><th>邮箱</th><th>等级</th></tr>'; //循环取出info对象中的数据 for(var i=0,n=info.length-1;i<n;i++){ str+='<tr><td>'+info[i].id+'</td><td>'+info[i].name+'</td><td>'+info[i].email+'</td><td>'+info[i].level+'</td></tr>'; } //分页链接 str+='<tr><td colspan="4" align="center">'; for(var i=1;i<=info[info.length-1];i++){ str+='<a href="javascript:void(0)" onclick="getPageList('+i+')">'+i+'</a> '; console.log(i); } str+='</td></tr>'; //把数据输出到浏览器 document.getElementById('result').innerHTML=str; } } req.send(null); } //默认显示第一页 window.onload=function(){ getPageList(1); } </script> <table id='result'></table> </body> </html>
