自己在项目中写的一个Jquery插件和Jquery tab 功能

后台查询结果 PDFSearchResult实体类：

  [DataContract(Name = "PDFSearchResult")]
    public class PDFSearchResult
    {

        public PDFSearchResult(string title, string fileUrl)
        {
            Title = title;
            FileUrl = fileUrl;
        }

        [DataMember(Name = "title")]
        public string Title { get; set; }

        [DataMember(Name = "fileUrl")]
        public string FileUrl { get; set; }

    }

另外，有一个PagedResult泛型类，PagedResult<T>

  [DataContract(Name = "pagedCollection", Namespace = "")]
    public class PagedResult<T>
    {
        public PagedResult(long totalItems, long pageNumber, long pageSize);

        [DataMember(Name = "items")]
        public IEnumerable<T> Items { get; set; }
        [DataMember(Name = "pageNumber")]
        public long PageNumber { get; }
        [DataMember(Name = "pageSize")]
        public long PageSize { get; }
        [DataMember(Name = "totalItems")]
        public long TotalItems { get; }
        [DataMember(Name = "totalPages")]
        public long TotalPages { get; }

        //
        // Summary:
        //     Calculates the skip size based on the paged parameters specified
        //
        // Remarks:
        //     Returns 0 if the page number or page size is zero
        public int GetSkipSize();
    }

后台，采用Web Api (/api/SearchApi/GetPDFSearchResults/), 返回值类型为 PagedResult<PDFSearchResult>, 是Json类型返回值

在页面表现UI层，有两个tab,左边的tab显示的是页面的搜索结果searchResult, 右边的tab显示的是pdf文件的搜索结果PDFSearchResult

页面SearchResult.cshtml如下:

<section id="searchListing" class="row search">
        <div>

            <div class="tabs">
                <ul class="tab">
                    <li data-ui="tab-nav"><a href="#">Web Page Results</a></li>
                    <li data-ui="tab-nav"><a href="#">PDF Results</a></li>
                </ul>
            </div>
                <div class="tabContent">
                    <div id="resultsArea" class="search-results" style="display:block;" data-ui="tab-content">
                        <div id="NoResultsMessage" style="display:none;">
                            <p class="results-title">No Results For<strong class="search-term"></strong>'</p>
                        </div>
                        <div id="HasResultsMessage" style="display:none;">
                            <p class="results-title">Search Results For<strong class="search-term"></strong>'</p>
                        </div>
                        <div class="results" id="SearchResultsContainer">
                            <article class="row">
                                <a href="#">
                                    <div>
                                        <h2></h2>
                                        <p></p>

                                        <p class="link">Read more</p>
                                    </div>
                                </a>
                            </article>
                        </div>
                        <ul class="pagination">
                            <li><a href="#" class="prev"><i class="gi icon-arrow"></i></a></li>
                            <li class="page"><a href="#"></a></li>
                            <li><a href="#" class="next"><i class="gi icon-arrow"></i></a></li>
                        </ul>
                    </div>
                    <div id="PDFResultArea" class="search-results" style="display:none;" data-ui="tab-content">
                        <div id="NoPDFResultsMessage" style="display:none;">
                            <p class="results-title">No Results For<strong class="search-term"></strong>'</p>
                        </div>
                        <div id="HasPDFResultsMessage" style="display:none;">
                            <p class="results-title">Search Results For<strong class="search-term"></strong>'</p>
                        </div>
                        <div class="results" id="SearchPDFResultsContainer">
                            <article class="row">
                                <a href="#">

                                </a>
                            </article>
                        </div>
                        <ul class="pagination">
                            <li><a href="#" class="prev"><i class="gi icon-arrow"></i></a></li>
                            <li class="page"><a href="#"></a></li>
                            <li><a href="#" class="next"><i class="gi icon-arrow"></i></a></li>
                        </ul>

                    </div>
                </div>
            </div>
</section>

这里，在页面展示上，应该看上去如下图：

为了在同一个页面，也就是SearchResult.cshtml中实现这个tab功能，我用JQuery写了个tab功能，如下

tab.js

function tabs(state,control,show){

    $(control + "> li").on(state, function(){

        $(this).addClass("on").siblings().removeClass("on");

        var index = $(this).index();

        $(show + "> div").eq(index).show().siblings().hide();
 })

    $(control + "> li").eq(0).attr("class", "on");
    $(show + "> div").eq(0).show();
}

tabs("click", ".tab", ".tabContent");

The css style 如下

.tabs {
  position: relative;
  margin-top: 60px;
  margin-bottom: 20px; }
  .tabs > ul {
    list-style: none;
    border-bottom: 1px solid #c0c0c0;
    margin-top:;
    padding:; }
    .tabs > ul > li {
      float: left;
      margin-bottom: -1px; }
      [dir="rtl"] .tabs > ul > li {
        float: right; }
      .tabs > ul > li a {
        display: block;
        line-height:;
        margin-right: .2rem;
        padding: 0 1rem;
        border: 1px solid transparent;
        text-decoration: none;
        cursor: pointer; }
        [dir="rtl"] .tabs > ul > li a {
          margin-right:;
          margin-left: .2rem; }
        .tabs > ul > li a:hover {
          background: #fff !important;
          border: 1px solid #fff !important;
          color: #ff7900; }
      .tabs > ul > li > [aria-selected="true"], .tabs > ul > li > [aria-selected="true"]:hover {
        background: red !important; }
    .tabs > ul li.on {
      background-color: #fff;
      border: 1px solid #c0c0c0;
      border-bottom-color: transparent;
      color: #454545;
      cursor: default; }
    .tabs > ul li.on a {
      color: #ff7900; }
  .tabs > * {
    display: none; }
  .tabs > ul,
  .tabs [tabIndex="0"] {
    display: block; }

然后，我写了一个Jquery Plugin来实现PDFSearchResult的展示功能，也就是说JSON结果，展示到SearchResult.cshtml页面上

在这个Jquery plugin中，调用ajax来调用web api (/api/SearchApi/GetPDFSearchResults/),返回json结果，展现到web页面上

view.pdfsearch.js

(function ($) {

    $.fn.PDFSearch = function (options) {

        return this.each(function () {

            var pdfSearch = $(this);

            pdfSearch.pdfResultArea = pdfSearch.find("#PDFResultArea");

            pdfSearch.noPDFResultMessage = pdfSearch.pdfResultArea.find("#NoPDFResultsMessage");
            pdfSearch.hasPDFResultMessage = pdfSearch.pdfResultArea.find("#HasPDFResultsMessage");
            pdfSearch.PDFResultContainer = pdfSearch.pdfResultArea.find("#SearchPDFResultsContainer");

            pdfSearch.searchPDFResultTemplate = pdfSearch.PDFResultContainer.find("article").clone();

            pdfSearch.queryField = $("input[name='search']");

            pdfSearch.searchTermLabel = $(".search-term");

            pdfSearch.oldTerm = undefined;
            pdfSearch.term = pdfSearch.queryField.val();

            //Paging elements
            pdfSearch.paginationWrapper = pdfSearch.pdfResultArea.find('ul.pagination');
            pdfSearch.pageTemplate = pdfSearch.paginationWrapper.find('.page').clone();
            pdfSearch.pagePrevious = pdfSearch.paginationWrapper.find('.prev');
            pdfSearch.pageNext = pdfSearch.paginationWrapper.find('.next');

            // Page tracking
            pdfSearch.pageSize = 10;
            pdfSearch.pageNumber = 1;
            pdfSearch.totalPages = 0;

            // Sets up pagination for search results.
            pdfSearch.paginate = function (data) {

                pdfSearch.totalPages = data.totalPages;
                pdfSearch.paginationWrapper.find('.page').remove();
                if (pdfSearch.totalPages > 1) {
                    pdfSearch.pagePrevious.toggle(data.pageNumber > 1);
                    pdfSearch.pageNext.toggle(data.pageNumber < pdfSearch.totalPages);

                    for (i = 1; i < pdfSearch.totalPages + 1; i++) {
                        var page = pdfSearch.pageTemplate.clone();
                        var link = page.find('a');
                        if (i == data.pageNumber)
                            page.addClass('active');
                        page.data('page', i);
                        link.text(i);

                        pdfSearch.pageNext.parent().before(page).before('\n\r');
                    }

                    pdfSearch.paginationWrapper.show(0);
                } else {
                    pdfSearch.paginationWrapper.hide(0);
                }
            }

            pdfSearch.previous = function (evt) {
                return pdfSearch.goToPage(evt, pdfSearch.pageNumber - 1);
            }

            pdfSearch.next = function (evt) {
                return pdfSearch.goToPage(evt, pdfSearch.pageNumber + 1);
            }

            pdfSearch.goToPage = function (evt, pageNumber) {
                pdfSearch.pageNumber = pageNumber || $(this).data('page');
                if (pdfSearch.pageNumber > pdfSearch.totalPages) pdfSearch.pageNumber = pdfSearch.totalPages - 1;
                if (pdfSearch.pageNumber < 1) pdfSearch.pageNumber = 1;

                pdfSearch.searchPDF();
                return false;
            }

            // filter change handler
            pdfSearch.handleQuery = function (evt) {

                pdfSearch.term = $(this).val();
                if (pdfSearch.oldTerm != pdfSearch.term) {
                    pdfSearch.oldTerm = pdfSearch.term;
                    pdfSearch.searchPDF();
                }
                return false;
            }

            pdfSearch.searchPDF = function () {
                pdfSearch.pdfResultArea.addClass("loading");

                $.ajax({
                    type: "GET",
                    url: "/umbraco/api/SearchApi/GetPDFSearchResults/",
