JSP - Help in generating fixed number of link in pagination
my pagination works good but I'm not able to understand how generate a fixed number of links to the pages. For example, I need to have 5 fixed links in this way: 1 - 2 - 3 - 4 - 5 > if I click on the third page I will see always 5 links: < 3 - 4 - 5 开发者_StackOverflow中文版- 6 -7 >
Now with my algorithm I'm only able to generate all the links, but I have no idea how create what I have explained above. This is my code(only for href generation):
<div class="pageBoxRight">
<c:if test="${param.pageNumber > 1}">
<a href="javascript: previousRecords();" class="previous"><em>previous</em></a>
</c:if>
<c:forEach var="i" begin="1" end="${tot + 1}" step="1" varStatus ="status">
<a href="javascript: goToPage(${i});" id="paginator${i}" class="pageNumber"><span class="pageNumberRight">${i}</span></a>
</c:forEach>
<c:if test="${param.pageNumber < tot}">
<a href="javascript: nextRecords();" class="next"><em>next</em></a>
</c:if>
</div>
Can someone help me? Thanks a lot.
It get complicated.
<c:set var="p" value="${param.pageNumber}" /> <%-- current page (1-based) --%>
<c:set var="l" value="5" /> <%-- amount of page links to be displayed --%>
<c:set var="r" value="${l / 2}" /> <%-- minimum link range ahead/behind --%>
<c:set var="t" value="${tot}" /> <%-- total amount of pages --%>
<c:set var="begin" value="${((p - r) > 0 ? ((p - r) < (t - l + 1) ? (p - r) : (t - l)) : 0) + 1}" />
<c:set var="end" value="${(p + r) < t ? ((p + r) > l ? (p + r) : l) : t}" />
<c:forEach begin="${begin}" end="${end}" var="page">
${page}...
</c:forEach>
