javascript實現json頁面分頁實例代碼
這篇文章主要介紹了javascript實現json頁面分頁實例代碼,需要的朋友可以參考下
下午有個朋友問json 數據怎麼分頁 就搗鼓了一個東東出來 下面直接代碼： 代碼如下: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>無標題文檔</title> <script> var a={"code":1,"list":[{"category1_id":"1","category1_name":"u9152u6c34u996eu6599","category1_intro":"u6e05u51c9u53efu53e3 u7684u9152u6c34u996eu6599","category1_images":"http://www.songcuomen.com/attachments/pro ductType/2014-01/10/21_1389343628.jpg"},{"category1_id":"2","category1_name":"u7c73u9762u7caeu6cb9","category1_intro":"u5bb6u5eadu5fc5u5907", "category1_images":"http://www.songcuomen.com/attachments/productType/2014-01/10/21_1389343865.jpg"},{"category1_id":"3","category1_name":"u7f8eu5bb9u6d17u62a4","category1_intro":"u62a4u80a4u5fc5u5907"," category1_images":"http://www.songcuomen.com/attachments/productType/2014-01/10/21_1389343935.jpg"},{"category1_id":"4","category1_name":"u6e05u6d01u6d17u6da4","category1_intro":"u7ed9u60a8u4e00u4e2a u5e72u51c0u7684u751fu6d3bu73afu5883","category1_images":"http://www.songcuomen.com/attachm ents/productType/2014-01/10/21_1389343986.jpg"},{"category1_id":"5","category1_name":"u751fu6d3bu7528u54c1","category1_intro":"u5bb6u5eadu5fc5u5907"," category1_images":"http://www.songcuomen.com/attachments/productType/2014-01/10/21_1389344445.jpg"},{"category1_id":"6","category1_name":"u4f11u95f2u98dfu54c1","category1_intro":"u597du5403u7f8eu5473", "category1_images":"http://www.songcuomen.com/attachments/productType/2014-01/10/21_1389344494.jpg"}]}; var y=1;//表示頁數 var t=2;//表示每頁現實幾條數據 var z=a["list"].length; var zy= Math.ceil(z/t); window.onload=function (){ fanye(0); } function fanye(f) { if(y==1 && f==-1) { alert('已經是第一頁了'); f=0; } if(y==zy && f==1) { alert('已經是最後一頁了'); f=0; } var otbod=document.getElementById('table').tBodies[0]; var s=otbod.rows.length; for(i=0;i<s;i++) { otbod.removeChild(otbod.rows[0]); } y+=f; var q=(y-1)*2;//頁數-1 乘以每頁現實多少條 結果為 本頁從第幾條開始 for(var i=1;i<3;i++) { var otr=document.createElement('tr'); var otd1=document.createElement('td'); var otd2=document.createElement('td'); var otd3=document.createElement('td'); var otd4=document.createElement('td'); otd1.innerHTML=a["list"][q]['category1_id']; otd2.innerHTML=a["list"][q]['category1_name']; otd3.innerHTML=a["list"][q]['category1_intro']; otd4.innerHTML=a["list"][q]['category1_images']; otr.appendChild(otd1); otr.appendChild(otd2); otr.appendChild(otd3); otr.appendChild(otd4); otbod.appendChild(otr); if(q==zy) { break; } q++; } } </script> </head> <body> <table border="1" id="table"> <thead> <tr><td>category1_id</td><td>category1_name</td><td>category1_intro</td><td>category1_images</td></tr> </thead> <tbody> </tbody> </table> <a href="javascript:fanye(1);">下一頁</a> <a href="javascript:fanye(-1);">上一頁</a> </body> </html>- 上一頁:js獲取和設置屬性的方法
