In my ASP.NET MVC 3 application I want to use Jquery’s pagination plugin to make my forum…
So I want, to do all page changes with Ajax, and want to use history plugin for working browser’s back and next buttons…
What the most efficient javascript/jquery code for that?
I wrote this code month ago, but now it seems me ugly..Check that
$(document).ready(function () {
$.history.init(function (hash) {
if (hash != "") {
NavigateToPage(hash.substring(0,hash.indexOf("page")),hash.substring(hash.lastIndexOf("_")+1));
} else {
if(firstTimeOpen==true){
firstTimeOpen=false;
}
else
{
window.location.replace("/Forum");
}
}
});
$(".more-button").click(function () {
currentForumId=$("#pagination-td").parent().prev().attr("id").substring(5);
$.history.load($(this).parents("tr").attr("id").substring(5)+"page_1");
});
});
function NavigateToPage(forumId,page) {
lastForumId=currentForumId;
currentForumId=forumId;
var elem=$("#forum"+forumId);
var elemStr="#forum"+forumId;
if($("#pagination-td").parent().prev().attr("id").substring(5)!=forumId)
{
forumChanged=true;
MakeChanges(elem,page);
}
else
{
if($(".pagination").html()==null)
{
if(elem.find("a").attr("id")>@MyProject.Constants.THREAD_COUNT)
{
$("#pagination-td").pagination(elem.find("a").attr("id"), {
items_per_page: @MyProject.Constants.THREAD_COUNT,
callback: handlePaginationClick
});
}
}
}
$.get('/Forum/ForumThreads', { id: forumId, beginNumber: page - 1, count: @MyProject.Constants.THREAD_COUNT }, function (data) {
RemoveElements(elem.prev(), @MyProject.Constants.THREAD_COUNT);
elem.before(data);
elem.hide();
$("tr:not("+elemStr+"):hidden").show(300);
});
CorrectPagination(page);
}
function RemoveElements(element)
{
if (element.hasClass("forum-desc")) return false;
var prevElement=element.prev();
element.remove();
RemoveElements(prevElement);
}
function MakeChanges(elem,page)
{
var element=elem.prev();
if(forumChanged==true)
{
$.get('/Forum/ForumThreads', { id: lastForumId, beginNumber:0, count: @MyProject.Constants.THREAD_VISIBLE_COUNT }, function (data) {
RemoveElements($("#pagination-td").parent().prev().prev());
$("#pagination-td").parent().prev().before(data);
$("#pagination-td").parent().prev().hide();
$("#pagination-td").parent().remove();
elem.after('<tr style="display:none"><td id="pagination-td" colspan="3" style="border-bottom:none;"></td></tr>');
if(elem.find("a").attr("id")> @MyProject.Constants.THREAD_COUNT)
{
$("#pagination-td").pagination(elem.find("a").attr("id"), {
items_per_page: @MyProject.Constants.THREAD_COUNT,
callback: handlePaginationClick
});
}
$("tr:hidden").show(300);
CorrectPagination(page);
$("#pagination-td").parent().prev().hide();
});
}
}
function handlePaginationClick(new_page_index,pagination_container)
{
$.history.load(currentForumId+"page_"+(new_page_index+1));
return false;
}
function CorrectPagination(page) {
$(".pagination span.current:not(.prev):not(.next)").replaceWith('<a href="#">' + $(".pagination span.current:not(.prev):not(.next)").html() + '</a>');
$(".pagination a:not(.prev):not(.next)").eq(page - 1).replaceWith('<span class="current">' + $(".pagination a:not(.prev):not(.next)").eq(page - 1).html() + "</span>");
if ($(".pagination span.current:not(.prev):not(.next)").next().html() == "Next") {
$(".pagination span.prev").replaceWith('<a class="prev" href="#">Prev</a>');
$(".pagination a.next").replaceWith('<span class="current next">Next</span>');
}
else {
if ($(".pagination span.current:not(.prev):not(.next)").prev().html() == "Prev") {
$(".pagination a.prev").replaceWith('<span class="current prev" >Prev</span>');
$(".pagination span.next").replaceWith('<a class="next" href="#">Next</a>');
}
else {
$(".pagination span.prev").replaceWith('<a class="prev" href="#">Prev</a>');
$(".pagination span.next").replaceWith('<a class="next" href="#">Next</a>');
}
}
}
There are threads of forum in page and I use one pagination(to active thread)… By clicking other more button, the current thread is changed to that thread.
So in the html I have this
<table id="forum-table" class="border-top">
@foreach (var forum in Model)
{
<tr class="forum-desc">
<td class="forum-name" colspan="4"><a class="label-h4 purple" href="/Forum/Forums/@forum.Key.Forum.Id">@forum.Key.Forum.Name</a>
@if (forum.Key.Forum.Description != null)
{
<span> - </span>
<span>@forum.Key.Forum.Description</span>
}</td>
</tr>
for(int index = 0; index < forum.Value.Count; index++)
{
<tr>
<td class="thread-pic"><img src="/img/forum/thread-icon.png" alt="" /></td>
<td class="thread-name">
<a href="/Forum/Thread/@forum.Value[index].Thread.Id" class="blue linked">@forum.Value[index].Thread.Title</a>
</td>
<td class="thread-post-count">
<span>Posts:</span>@forum.Value[index].PostCount
</td>
<td class="thread-information">
<span>by </span><a class="blue" href="/Home/UserProfile/@forum.Value[index].LastPostUserName">@forum.Value[index].LastPostUserName</a> <br />
@if (forum.Value[index].LastPostDate != DateTime.MinValue)
{
@forum.Value[index].LastPostDate
}
</td>
</tr>
}
if (forum.Key.ThreadCount > @MyProject.Constants.THREAD_VISIBLE_COUNT)
{
<tr id="forum@(forum.Key.Forum.Id)">
<td class="more-td">
<a href="javascript:void" class="blue linked more-button" id="@forum.Key.ThreadCount">more</a>
</td>
</tr>
}
if (forum.Key.Forum.Id == Model.Keys.FirstOrDefault().Forum.Id)
{
<tr style="display:none">
<td id="pagination-td" colspan="3" style="border-bottom:none;"></td>
</tr>
}
if (forum.Key.ThreadCount == 0)
{
<tr>
<td colspan="4"><span>No threads available in this forum</span></td>
</tr>
}
}
</table>
So I want shortest(efficient) javascript/jquery code for mixing this two plugins.
Dylan, I think changing
parent().prev()withclosest()isn’t anything big problem… There are such a big problems with large code… For example take a look at that functionIn that question I found a more efficient slutuion for it… Take a look at this
jquery history plugin set current page possible?
There is same function with less code
And then
Let’s check yourself…For other functions may be shortest way too…
