• jQuery----分页插件实现


    1、效果

    2、html代码

    <!DOCTYPE html>
    <html>
    <head>
        <meta charset="utf-8">
        <title>jquery 分页插件</title>
        <link rel="stylesheet" type="text/css" href="css/pagination.less">
    </head>
    <body>
        <div class="pagination-container" id = 'pagination-container'>
        </div>
        <script type="text/javascript" src='js/jquery-2.2.1.min.js'></script>
        <script type="text/javascript" src='js/pagination.js'></script>
    </body>
    </html>
    

    3、less代码

    .pagination-container{
    	 800px;
    	height: 80px;
    	margin: 0 auto;
    	text-align: center;
    	.div{
    		height: 40px;
    		line-height: 30px;
    		margin: 0 auto;
    		div{
    			display: inline-block;
    		}
    		input,span,a{
    			margin: 0 10px 0 0;
    		}
    		input{
    			 40px;
    			height: 20px;
    		}
    		.search-page-btn{
    			height: 20px;
    			padding: 4px 10px;
    			background-color: #568DBD;
    			color: white;
    			border: 1px solid #568DBD;
    			&:hover{
    				background-color: #4681AF;
    			}
    		}
    		a{ 
    			padding: 6px 10px;
    			border: 1px solid #C5B7B7;
    			text-decoration: none;
    			color: #888888;
    			font-size: 12px;
    			&:hover{
    				border: 1px solid #568DBD;
    			}
    		}
    		.choose{
    			background-color: #568DBD;
    			color: white;
    			font-weight: bold;
    		}
    	}
    }
    

      4、jquery代码

    var pagination = $("#pagination-container");
    var now_page = 1;
    var total_page = 30;
    createPagination(pagination, now_page, total_page);
    function createPagination(pagination, now_page, total_page) {
        initPagination();
        addPaginationEvent();
        function initPagination() {
            pagination.empty();
            var lineOne = $("<div class = 'div'>" +
                "<span>当前页:</span>" +
                "<span class='now-page num'>" + now_page + "</span>" +
                "<span>/</span>" +
                "<span class='num total-page'>" + total_page + "</span>" +
                "<span>跳转到</span>" +
                "<input type='number' name='number' class='jump-top-page' value = '" + now_page + "' tabindex = '1'>" +
                "<a href='#' class='search-page-btn'>确定</a>" +
                "</div>");
            pagination.append(lineOne);
            var pageObj = $("<div class = 'div'>" +
                "<div class = 'left'>" +
                "<a href='#' class='first-page'>首页</a>" +

                "</div>" +
                "<div class = 'center'>" +
                "</div>" +
                "<div class = 'right'>" +
                "<a href='#' class='next-page'>下一页></a>" +
                "<a href='#' class='last-page'>尾页</a>" +
                "</div>" +
                "</div>");
            pagination.append(pageObj);
            fillNumberPage(1);
        }
        function addPaginationEvent() {
            var searchBtn = pagination.find(".search-page-btn");
            var firstPageBtn = pagination.find(".first-page");
            var lastPageBtn = pagination.find(".last-page");
            var prevPageBtn = pagination.find(".prev-page");
            var nextPageBtn = pagination.find(".next-page");
            var prevPagesBtn = pagination.find(".prev-pages");
            var nextPagesBtn = pagination.find(".next-pages");
            var searchVal = pagination.find(".jump-top-page");
            searchBtn.on("click", function() {
                var searchVal = pagination.find(".jump-top-page");
                var page = parseInt(searchVal.val());
                if (page <= total_page && page > 0) {
                    now_page = page;
                    fillNumberPage(page);
                }
            })
            firstPageBtn.on("click", function() {
                if (now_page != 1) {
                    fillNumberPage(1);
                    now_page = 1;
                }
            })
            lastPageBtn.on("click", function() {
                if (now_page != total_page) {
                    now_page = total_page;
                    fillNumberPage(total_page);
                }
            })
            prevPageBtn.on("click", function() {
                if (now_page > 1) {
                    now_page--;
                    fillNumberPage(now_page);
                }

                if (now_page < total_page) {
                    now_page++;
                    fillNumberPage(now_page);
                }
            })
            pagination.on("click", ".page", function() {
                var page = parseInt($(this).attr("data-page"));
                now_page = page;
                fillNumberPage(page);
            })
    
             $(document).on("keydown",function(event){
             	if(event.keyCode == '13'){
             		 searchBtn.click();
             	}
             })
        }
    
        function fillNumberPage(page) {
            pagination.find(".center").empty();
            pagination.find(".now-page").text(page);
            pagination.find(".jump-top-page").val(page);
            var start;
            var end;
            var p = page;
            if (total_page <= 7) {
                start = 1;
                end = total_page;
            } 
            else {
                if (page <= 4) {
                    start = 1;
                    end = 7;
                } else if (page > 4 && page < total_page - 4) {
                    start = page - 3;
                    end = page + 3;
                } else {
                    start = total_page - 7;
                    end = total_page;
                }
            }
            for (var i = start; i <= end; i++) {
                var pageCenter = $("<a href='#' class='page' data-page = '" + i + "'>" + i + "</a>");
                if (i == p) {
                    pageCenter.addClass("choose");
                }
                pagination.find(".center").append(pageCenter);
            }
        }
    }
    

      5、总结

    将父节点,当前页,总页数传给创建函数就可以生成分页。

    (还没加跳页的功能)
