Hi,
I am retrieving all records from database and displaying in table using JSP.
my problem is i want to show 10 records at a time only.. i dont need to show all records at a time. when i click previous and next link then it has to move.
i am using JavaScript for this it working well and it showing 10 records at a time but it displays all the page numbers in current page. i dont want to show all the page numbers in current page. will u please help me for this
This is i am using JS file:
function Pager(tableName, itemsPerPage) {
this.tableName = tableName;
this.itemsPerPage = itemsPerPage;
this.currentPage = 1;
this.pages = 0;
this.inited = false;
this.showRecords = function(from, to) {
var rows = document.getElementById(tableName).rows;
// i starts from 1 to skip table header row
for (var i = 1; i < rows.length; i++) {
if (i < from || i > to)
rows.style.display = 'none';
else
rows.style.display = '';
}
}
this.showPage = function(pageNumber) {
if (! this.inited) {
alert("not inited");
return;
}
var oldPageAnchor = document.getElementById('pg'+this.currentPage);
oldPageAnchor.className = 'pg-normal';
this.currentPage = pageNumber;
var newPageAnchor = document.getElementById('pg'+this.currentPage);
newPageAnchor.className = 'pg-selected';
var from = (pageNumber - 1) * itemsPerPage + 1;
var to = from + itemsPerPage - 1;
this.showRecords(from, to);
}
this.prev = function() {
if (this.currentPage > 1)
this.showPage(this.currentPage - 1);
}
this.next = function() {
if (this.currentPage < this.pages) {
this.showPage(this.currentPage + 1);
}
}
this.init = function() {
var rows = document.getElementById(tableName).rows;
var records = (rows.length - 1);
this.pages = Math.ceil(records / itemsPerPage);
this.inited = true;
}
this.showPageNav = function(pagerName, positionId) {
if (! this.inited) {
alert("not inited");
return;
}
var element = document.getElementById(positionId);
var pagerHtml = '<span onclick="' + pagerName + '.prev();" class="pg-normal"> « Prev </span> | ';
for (var page = 1; page <= this.pages; page++)
pagerHtml += '<span id="pg' + page + '" class="pg-normal" onclick="' + pagerName + '.showPage(' + page + ');">' + page + '</span> | ';
pagerHtml += '<span onclick="'+pagerName+'.next();" class="pg-normal"> Next »</span>';
element.innerHTML = pagerHtml;
}
}
