Jquery外掛程式實現分頁查詢__Jquery

1.情境分析

    近期在項目中很多地方都用到了分頁查詢，今天筆者就前端的Jquery外掛程式實現分頁詳細地跟大家講解下，希望能協助到需要的各位。 2.實現方案

①page.css樣式代碼

.page{        list-style: none;        }        .page>li{        float: left;        padding: 5px 10px;        cursor: pointer;        }        .page .pageItem{        border: solid thin #DDDDDD;        margin: 5px;        }        .page .pageItemActive{        border: solid thin #0099FF;        margin: 5px;        background-color: #0099FF;        color:white;        }        .page .pageItem:hover{        border: solid thin #0099FF;        background-color: #0099FF;        color:white;        }        .page .pageItemDisable{        border: solid thin #DDDDDD;        margin: 5px;        background-color: #DDDDDD;        }

②page.js動效代碼

 /**     * Created by zhangxing on 2017/4/26.     */    var  page = {            "pageId":"",        "data":null,        "maxshowpageitem":5,//最多顯示的頁碼個數        "pagelistcount":10,//每一頁顯示的內容條數        "init":function(listCount,currentPage,options){        this.data=options.data,        this.pageId=options.id,        this.maxshowpageitem=options.maxshowpageitem,//最多顯示的頁碼個數        this.pagelistcount=options.pagelistcount//每一頁顯示的內容條數        page.initPage(listCount,currentPage);        },        /**         * 初始化資料處理         * @param listCount 列表總量         * @param currentPage 當前頁         */        "initPage":function(listCount,currentPage){        var maxshowpageitem = page.maxshowpageitem;        if(maxshowpageitem!=null&&maxshowpageitem>0&&maxshowpageitem!=""){        page.maxshowpageitem = maxshowpageitem;        }        var pagelistcount = page.pagelistcount;        if(pagelistcount!=null&&pagelistcount>0&&pagelistcount!=""){        page.pagelistcount = pagelistcount;        }        page.pagelistcount=pagelistcount;        if(listCount<0){        listCount = 0;        }        if(currentPage<=0){        currentPage=1;        }        page.setPageListCount(listCount,currentPage);        },        /**         * 初始化分頁介面         * @param listCount 列表總量         */        "initWithUl":function(listCount,currentPage){        var pageCount = 1;        if(listCount>=0){        var pageCount = listCount%page.pagelistcount>0?parseInt(listCount/page.pagelistcount)+1:parseInt(listCount/page.pagelistcount);        }        var appendStr = page.getPageListModel(pageCount,currentPage);        $("#"+page.pageId).html(appendStr);        },        /**         * 設定列表總量和當前頁碼         * @param listCount 列表總量         * @param currentPage 當前頁碼         */        "setPageListCount":function(listCount,currentPage){        listCount = parseInt(listCount);        currentPage = parseInt(currentPage);        page.initWithUl(listCount,currentPage);        page.initPageEvent(listCount);        page.viewPage(currentPage,listCount,page.pagelistcount,page.data)//      fun(currentPage);        },        //頁面顯示功能        "viewPage":function (currentPage,listCount,pagelistcount,data){        var NUM=listCount%pagelistcount==0?listCount/pagelistcount:parseInt(listCount/pagelistcount)+1;        if(currentPage==NUM){        var result=data.slice((currentPage-1)* pagelistcount,data.length);        }        else{        var result=data.slice((currentPage-1)*pagelistcount,(currentPage-1)*pagelistcount+pagelistcount);        }        options.callBack(result);        },        "initPageEvent":function(listCount){        $("#"+page.pageId +">li[class='pageItem']").on("click",function(){        page.setPageListCount(listCount,$(this).attr("page-data"),page.fun);        });        },        "getPageListModel":function(pageCount,currentPage){        var prePage = currentPage-1;        var nextPage = currentPage+1;        var prePageClass ="pageItem";        var nextPageClass = "pageItem";        if(prePage<=0){        prePageClass="pageItemDisable";        }        if(nextPage>pageCount){        nextPageClass="pageItemDisable";        }        var appendStr ="";        appendStr+="<li class='"+prePageClass+"' page-data='1' page-rel='firstpage'>首頁</li>";        appendStr+="<li class='"+prePageClass+"' page-data='"+prePage+"' page-rel='prepage'>&lt;上一頁</li>";        var miniPageNumber = 1;        if(currentPage-parseInt(page.maxshowpageitem/2)>0&&currentPage+parseInt(page.maxshowpageitem/2)<=pageCount){        miniPageNumber = currentPage-parseInt(page.maxshowpageitem/2);        }else if(currentPage-parseInt(page.maxshowpageitem/2)>0&&currentPage+parseInt(page.maxshowpageitem/2)>pageCount){        miniPageNumber = pageCount-page.maxshowpageitem+1;        if(miniPageNumber<=0){        miniPageNumber=1;        }        }        var showPageNum = parseInt(page.maxshowpageitem);        if(pageCount<showPageNum){        showPageNum = pageCount;        }        for(var i=0;i<showPageNum;i++){        var pageNumber = miniPageNumber++;        var itemPageClass = "pageItem";        if(pageNumber==currentPage){        itemPageClass = "pageItemActive";        }        appendStr+="<li class='"+itemPageClass+"' page-data='"+pageNumber+"' page-rel='itempage'>"+pageNumber+"</li>";        }        appendStr+="<li class='"+nextPageClass+"' page-data='"+nextPage+"' page-rel='nextpage'>下一頁&gt;</li>";        appendStr+="<li class='"+nextPageClass+"' page-data='"+pageCount+"' page-rel='lastpage'>尾頁</li>";        return appendStr;        }        }

③首頁面query.html代碼
