原理：所有數據已加載好，js通過遍歷部分顯示，實現分頁效果

</html>js實現分頁
/**
* 分頁函數
* pno--頁數
* psize--每頁顯示記錄數
* 分頁部分是從真實數據行開始，因而存在加減某個常數，以確定真正的記錄數
* 純js分頁實質是數據行全部加載，通過是否顯示屬性完成分頁功能
**/
function goPage(pno,psize){
var itable = document.getElementById("idData");
var num = itable.rows.length;//表格所有行數(所有記錄數)
console.log(num);
var totalPage = 0;//總頁數
var pageSize = psize;//每頁顯示行數
//總共分幾頁
if(num/pageSize > parseInt(num/pageSize)){
totalPage=parseInt(num/pageSize)+1;
}else{
totalPage=parseInt(num/pageSize);
}
var currentPage = pno;//當前頁數
var startRow = (currentPage - 1) * pageSize+1;//開始顯示的行 31
var endRow = currentPage * pageSize;//結束顯示的行 40
endRow = (endRow > num)? num : endRow; 40
console.log(endRow);
//遍歷顯示數據實現分頁
for(var i=1;i<(num+1);i++){
var irow = itable.rows[i-1];
if(i>=startRow && i<=endRow){
irow.style.display = "block";
}else{
irow.style.display = "none";
}
}
var pageEnd = document.getElementById("pageEnd");
var tempStr = "共"+num+"條記錄 分"+totalPage+"頁 當前第"+currentPage+"頁";
if(currentPage>1){
tempStr += "<a href=\"#\" onClick=\"goPage("+(1)+","+psize+")\">首頁</a>";
tempStr += "<a href=\"#\" onClick=\"goPage("+(currentPage-1)+","+psize+")\"><上一頁</a>"
}else{
tempStr += "首頁";
tempStr += "<上一頁";
}
if(currentPage<totalPage){
tempStr += "<a href=\"#\" onClick=\"goPage("+(currentPage+1)+","+psize+")\">下一頁></a>";

}效果：
