Struts2 pagination
My Struts2 application needs the pagination functionality applied to some records, but what I need to customize is the "Last 1 - 2 - 3 Next" appearance and also have the ability to use a combo box for the selection of how many records should be visible(10 - 20 - 30 - 40 -50).
I have tried two way to accomplish this goal: 1) use display tag library, but I'm not able to customize the appearance, because is auto-generated by the library, and I don't how implement the combo box for select how many records should be visible 2) create my own code for accomplish this functio开发者_开发知识库nality but is a job too long and not enough time due to the expiry. My question is: exists some Struts2 library for realize this functionality? Or, is possible to customize the display tag library for the page scroll bar and the records combo box?
I can give insight from struts2 code base there is no functionality as described by you provided by struts2 in itself..
Regarding the Display tag i have not used them much but since they are the part of oprn source i am sure we can customize that one more thing regarding the customization of display tag ask question under display tag you will get better answer at at quick pace
I wrote a custom tld just for the purpose as below and then just use it like this:
Usage:
paginate.tag 1}">
<c:set var="showingPage"
value="${param.pageNumber == null ? 1 : param.pageNumber}" />
<c:url value="${postUrl}" var="previousUrl">
<c:param name="pageNumber" value="${showingPage - 1}" />
<c:param name="perPage" value="${perPage}" />
</c:url>
<c:url value="${postUrl}" var="nextUrl">
<c:param name="pageNumber" value="${showingPage +1}" />
<c:param name="perPage" value="${perPage}" />
</c:url>
<div class="pagination" />
<c:if test="${showingPage > 1}">
<a href="${previousUrl}"> << Previous</a>
</c:if>
<fmt:formatNumber var="endCounter" pattern="0">
<%= totalCount % perPage > 0 ? Math.ceil(totalCount/perPage) + 1 : totalCount/perPage %>
</fmt:formatNumber>
<c:forEach begin="1" end="${endCounter}" var="index">
<c:url value="${postUrl}" var="url">
<c:param name="pageNumber" value="${index}" />
<c:param name="perPage" value="${perPage}" />
</c:url>
<a href="${url}" class="${index == showingPage ? 'selected' : ''}">${index}</a>
</c:forEach>
<c:if test="${endCounter != showingPage}">
<a href="${nextUrl}"> Next >></a>
</c:if>
</div>
</c:if>
